Periodical surveys of oil content meters
(Annex I, Regulation 15(3))
A periodical survey of an oil discharge monitoring and control system would include a functional test asdescribed in Resolution MEPC 13(19) but not a test with oil to verify the continuing accuracy of the oilcontent meter.
Operational manuals for oil dischargemonitoring and control systems
(Annex I, Regulation 15(3) (c))
For compliance with Regulation 15(3) (a) and (c) of MARPOL 73/78 - Annex I and IMO Resolutions A 496 (XII) and MEPC 13 (19), the Oil Discharge Monitoring and Control System Operational Manualis to contain all the details necessary to operate and maintain the system and should include at least thefollowing information. The information may be grouped as indicated, or in an equivalent manner.
Introduction : Particulars of the ship, together with the date on which the system was/is to be installed and index to remainder of manual.Text of Regulations 15(3) (a) and 9(1) to be quoted in full.
Section 1 : Manufacturer's equipment manuals for major components of the system. These may include installation, commissioning, operating and fault finding procedures for the oil content monitor.
Section 2 : Operations manual comprising a description of the ship's cargo ballast systems, designated overboard discharges with sampling points, normal operational procedures, automatic inputs, manual inputs (as applicable), starting interlock and discharge valve control (as applicable), override system, audible and visual alarms, outputs recorded and, where required for manual input, flow rate when discharging by gravity and when pumping ballast overboard. It should also include instructions for the discharge of oily water following mal-function of the equipment.The above information is to be supported by copies of relevant approved diagrams.Reference may be made to Section 1, where applicable.
Section 3 : Technical manual comprising fault finding schedules, maintenance record and electrical, pneumatic and hydraulic schematic diagrams and descriptions of the complete system.Reference may be made to Section 1, where applicable.
Section 4 : Test and check-out procedures to include a functional test at installation and guidance notes for the Surveyors carrying out initial and in-service surveys.Reference may be made to Section 1, where applicable.
Appendix I : Technical installation specification including location and mounting of components, arrangements for maintaining integrity of 'safe' zones, safety requirements for electrical equipment installed in hazardous zones supported by copies of approved drawings, sample piping layout and sample delay calculations, design and arrangements of sampling probes, flushing arrangements and zero setting.Reference may be made to Section 1, where applicable.

Machinery space oil discharge monitoringand control systems
(Annex I, Regulation 16(5))
As neither Regulation 16(5) nor Resolution A444(XI) specifically require it, a Classification Societycannot insist on automatic recording of date and time in an oil discharge monitoring and control systemprovided for 100 ppm oily water separating equipment.
Discharge of segregated ballast
(Annex I, Regulation 18(6))
For new construction ships, an overboard discharge outlet for segregated ballast should be providedabove the deepest ballast waterline in order to facilitate compliance with Regulation 18(6).For other ships (without this facility), the Regulation requires that the surface of the ballast water beexamined immediately before discharge, to ensure that no contamination with oil has taken place.Further guidance from the Committee on how this should be done would be appreciated, particularly inthe case of double bottom tanks. One solution could be the provision of a sampling line to the oilcontent meter or an arrangement similar to a part flow system.
Minimum vertical depth of each doublebottom tank or space
(Annex I, Regulation 13E (4) (b))
For the purpose of determining the minimum vertical depth of each double bottom tank or space to betaken into account when calculating the protecting area PAg, suction wells may be neglected, providedsuch wells are not excessive in area and extend below the cargo tank for a minimum distance and in nocase more than half the height of the double bottom tank or space.

Calculation of the aggregate capacity ofSBT(Regulation 13F (3) (d) 4.12
In calculating the aggregate capacity under regulation 13F (3) (d), the following should be taken intoaccount:
.1 the capacity of engine-room ballast tanks should be excluded from the aggregate capacity ofballast tanks;
.2 the capacity of ballast tank located inboard of double hull should be excluded from the aggregatecapacity of ballast tanks (see figure 1).
Note: This IACS Unified Interpretation was submitted to IMO and is contained in MEPC/Circ. 316 of25th July 1996.

Interpretation to MARPOL I/27 Regulation 27 Intact stability 1 Every oil tanker of 5,000 tonnes deadweight and above delivered on or after 1 February 2002, as defined in regulation 1.28.7, shall comply with the intact stability criteria specified in paragraphs 1.1 and 1.2 of this regulation, as appropriate, for any operating draught under the worst possible conditions of cargo and ballast loading, consistent with good operational practice, including intermediate stages of liquid transfer operations. Under all conditions the ballast tanks shall be assumed slack. .1 In port, the initial metacentric height GMo, corrected for the free surface measured at 0°
heel, shall be not less than 0.15 m; .2 At sea, the following criteria shall be applicable: .2.1 the area under the righting lever curve (GZ curve) shall be not less than 0.055
m.rad up to θ = 30° angle of heel and not less than 0.09 m.rad up to θ = 40° or other angle of flooding fθ * if this angle is less than 40°. Additionally, the area under the righting lever curve (GZ curve) between the angles of heel of 30° and 40° or between 30° and fθ , if this angle is less than 40°, shall be not less than 0.03 m.rad;
.2.2 the righting lever GZ shall be at least 0.20 m at an angle of heel equal to or
greater than 30°; .2.3 the maximum righting arm shall occur at an angle of heel preferably exceeding
30° but not less than 25°; and .2.4 the initial metacentric height GMo, corrected for free surface measured at 0° heel,
shall be not less than 0.15 m. * fθ is the angle of heel at which openings in the hull superstructures or deckhouses which cannot be closed weathertight immerse. In applying this criterion, small openings through which progressive flooding cannot take place need not be considered as open. Note: 1. This UI is to be uniformly implemented by IACS Members and Associates from 1 April
2005. 2. The damage stability requirements in MARPOL I/28 shall not apply for the purpose of
demonstrating compliance with MARPOL Reg. I/27. 3. Rev.1 of this UI is to be uniformly implemented by IACS Societies from 1 July 2013.

2 The requirements of paragraph 1 of this regulation shall be met through design measures. For combination carriers simple supplementary operational procedures may be allowed. 3 Simple supplementary operational procedures for liquid transfer operations referred to in paragraph 2 of this regulation shall mean written procedures made available to the master which: .1 are approved by the Administration; .2 indicate those cargo and ballast tanks which may, under any specific condition of
liquid transfer and possible range of cargo densities, be slack and still allow the stability criteria to be met. The slack tanks may vary during the liquid transfer operations and be of any combination provided they satisfy the criteria;
.3 will be readily understandable to the officer-in-charge of liquid transfer operations; .4 provide for planned sequences of cargo/ballast transfer operations; .5 allow comparisons of attained and required stability using stability performance
criteria in graphical or tabular form; .6 require no extensive mathematical calculations by the officer-in-charge; .7 provide for corrective actions to be taken by the officer-in-charge in case of
departure from recommended values and in case of emergency situations; and .8 are prominently displayed in the approved trim and stability booklet and at the
cargo/ballast transfer control station and in any computer software by which stability calculations are performed.
Interpretation For proving compliance with Reg. I/27, either paragraph 1 or 2, below, shall be applied. 1. The vessel shall be loaded with all cargo tanks filled to a level corresponding to the maximum combined total of vertical moment of volume plus free surface inertia moment at 0° heel, for each individual tank. Cargo density shall correspond to the available cargo deadweight at the displacement at which transverse KM reaches a minimum value, assuming full departure consumables and 1% of the total water ballast capacity. The maximum free surface moment shall be assumed in all ballast conditions. For the purpose of calculating GMo, liquid free surface corrections shall be based on the appropriate upright free surface inertia moment. The righting lever curve may be corrected on the basis of liquid transfer moments. 2. An extensive analysis covering all possible combinations of cargo and ballast tank loading is to be carried out. For such extensive analysis conditions it is considered that: (a) Weight, centre of gravity co-ordinates and free surface moment for all tanks are to
be according to the actual content considered in the calculations. (b) The extensive calculations are to be carried out in accordance with the following:

MPC 11 (cont)
1. The draughts are to be varied between light ballast and scantling draught. 2. Consumables including but not restricted to fuel oil, diesel oil and fresh
water corresponding to 97%, 50% and 10% content are to be considered. 3. For each draught and variation of consumables, the available deadweight is
to comprise ballast water and cargo, such that combinations between maximum ballast and minimum cargo and vice-versa, are covered. In all cases the number of ballast and cargo tanks loaded is to be chosen to reflect the worst combination of VCG and free surface effects. Operational limits on the number of tanks considered to be simultaneously slack and exclusion of specific tanks are not permitted. All ballast tanks are to have at least 1% content.
4. Cargo densities between the lowest and highest intended to be carried are
to be considered. 5. Sufficient steps between all limits are to be examined to ensure that the
worst conditions are identified. A minimum of 20 steps for the range of cargo and ballast content, between 1% and 99% of total capacity, are to be examined. More closely spaced steps near critical parts of the range may be necessary.
At every stage the criteria described in MARPOL Reg. I/27 paragraphs 1.1 and 1.2 are to be met.

Chapter 2.2.4 reads as follows:
There are engines which, due to their size, construction and delivery schedule, cannot be pre-certified on a test-bed. In such cases, the engine manufacturer, shipowner or ship builder shallmake application to the Administration requesting an on-board test (see 2.1.2.2). The applicantmust demonstrate to the Administration that the on-board test fully meets all of therequirements of a test-bed procedure as specified in chapter 5 of this Code. Such a survey maybe accepted for one engine or for an engine group represented by the parent engine only, but itshall not be accepted for an engine family certification. In no case shall an allowance begranted for possible deviations of measurements if an initial survey is carried on board a shipwithout any valid pre-certification test.
Interpretation:
For engines undergoing an on-board certification test, to be issued with an EIAPP Certificate,the same procedure apply as if the engine had been pre-certified on a test-bed:
(a) the survey on-board meets the pre-certification survey requirements; and
(b) the on-board test fully meets all of the requirements of a test-bed procedure as specified in chapter 5 of the NOx Technical Code; and

Resolution 2 of the 1997 MARPOL ConferenceTechnical Code on Control of Emission ofNitrogen Oxides from Marine Diesel EnginesChapter 2.2.5
Chapter 2.2 Procedures for pre-certification of an Engine Group
Chapter 2.2.5 reads as follows:If the pre-certification test results show that an engine fails to meet the NOx emission limits asrequired by regulation 13 of Annex VI, a NOx–reducing device may be installed. This device,when installed on the engine, must be recognised as an essential component of the engine andits presence will be recorded in the engine’s technical file. To receive an EIAPP Certificate forthis assembly, the engine, including the reducing device, as installed, must be re-tested to showcompliance with the NOx emission limits. However, in this case, the assembly may be retestedin accordance with the simplified measurement method addressed in 6.3. The NOx–reducingdevice shall be included on the EIAPP Certificate together with all other records requested bythe Administration. The engine’s technical file shall also contain on-board NOx verificationprocedures for the device to ensure it is operating correctly.
Interpretation:
This section shall be interpreted as follows:
(a) An engine does not need to be shown, at the pre-certification survey, to fail to meet the Regulation 13 NOx emission limit requirements before a NOx reducing device is installed. Where it is intended from the outset that a NOx reducing device is to be fitted in accordance with Regulation 13(3)(b)(i) then the whole assembly shall be tested in accordance with the requirements of the test bed procedure as specified in Chapter 5.
In those cases where it is proposed that the engine with a NOx-reducing device is to be tested onboard to demonstrate compliance, as a ‘Parent Engine + device’ the requirements of 2.2.4 shall apply.
(b) Where the pre-certification test of an engine, undertaken in accordance with Chapter 5, shows that a NOx reducing device would need to be fitted in order to meet the Regulation 13 NOx emission limit requirements, and the whole assembly is subsequentlyretested in accordance with the simplified measurement method, the test reports from both the engine pre-certification test and the subsequent simplified measurement method test shall be included in the Technical File.
Where the simplified measurement method is used to verify that the whole assembly meets the Regulation 13 NOx emission limit requirements the allowances as given under 6.3.11 shall not be granted.
(c) In cases (a) and (b) the approval is on the basis of the complete assembly of engine and NOx reduction device. Consequently Item 1.15 of the Supplement to EIAPP Certificate shall give the actual NOx emission value (g/kWh) for the engine with the NOx reduction device in operation.
(d) The efficiency of the NOx–reducing device (as demonstrated) shall be considered as unique to the Engine Group as tested and therefore non-transferable. Hence should the same NOx – reducing device be used for another Engine Group the whole assemblage (engine + NOx reducing device) shall be tested. An after-treatment device shall not be certified independent of the engine to which it is to be coupled.

In those cases where the Technical File includes tolerances in respect of NOx emission settings then the effect upon the as measured emission value of those tolerances shall be stated and the basis of the emission value, as stated under 1.15 of the EIAPP Certificate, be given. In no cases shall the effect tolerances be such as to exceed the limit value as stated under 1.14 of the EIAPP Certificate.

The shipowner shall have the option of direct measurement of NOx emissions during engineoperation. Such data may take the form of spot checks logged with other engine operating dataon a regular basis and over the full range of engine operation or may result from continuousmonitoring and data storage. Data must be current (taken within the last 30 days) and must havebeen acquired using the test procedures cited in this NOx Technical Code. These monitoringrecords shall be kept on board for three months for verification purposes by the Parties to theProtocol of 1997. Data shall also be corrected for ambient conditions and fuel specification, andmeasuring equipment must be checked for correct calibration and operation, in accordance withthe procedures specified by the measurement equipment manufacturer in the engine’s technicalfile. Where exhaust gas after-treatment devices are fitted which influence the NOx emissions,the measuring point(s) must be located downstream of such devices.
Interpretation:
For application of this section it shall be interpreted that any system or procedure utilised tomonitor engine NOx emissions by the direct measurement method shall meet the requirementsof MEPC Resolution 103(49) ‘Guidelines for On-board NOx Verification Procedure – DirectMeasurement and Monitoring Method’.

Chapter 2.3.11 reads as follows:
If any adjustment or modification is made which is outside the approved limits documented inthe technical file, the IAPP Certificate may be issued only if the overall NOx emissionperformance is verified to be within the required limits by: a direct on-board NOx monitoring,as approved by the Administration; a simplified on-board NOx measurement; or, reference tothe test-bed testing for the relevant engine group approval showing that the adjustments ormodifications do not exceed the NOx emission limits.
Interpretation:
This section shall be interpreted as follows:
(a) Verification by the direct on-board NOx monitoring method is only applicable to the re-issue of IAPP Certificates at periodical surveys or their endorsement at intermediate / annual surveys.
(b) The demonstration of compliance in accordance with either direct on-board NOxmonitoring or simplified on-board NOx measurement does not establish a new Engine Group but does define the on-board verification procedure to be used thereafter to verify continuing compliance for that particular engine.
In these instances it shall be understood that the Parent Engine emission value, as given in the EIAPP Certificate, thereafter only relates to the condition of that engine at the Pre-certification Survey stage.

Interpretation:
For application of this section the term “according to those specifications” shall be interpretedas follows:
(a) It is considered that in this context “specification” may be read as identification marking and as such the identification of a NOx influencing component by a manufacturer’s part number or specific marking scheme would be sufficient.
In such instances the identification marking would be tied to a particular drawing or other data defining the features of that component with regard to its influence on NOx formation in the combustion process. Those drawings or other data shall form part of the conformity of production procedures as required under Chapter 4.
(b) The “specification” need only address those aspects of the design of the component which directly affect its function as a NOx critical component. For some components it may be possible to define these components by means of an outline dimensioned drawingwithin the conformity of production procedures or as a drawing directly included within the Technical File.

Chapter 4 Approval for serially manufactured engines: engine family and engine group concepts
Chapter 4.1 General
Chapter 4.1.1 reads as follows:To avoid certification testing of every engine for compliance with the NOx emission limits, oneof two approval concepts may be adopted, namely the engine family or the engine groupconcept.
Chapter 4.1.2 reads as follows:The engine family concept may be applied to any series-produced engines which, through theirdesign, are proven to have similar NOx emission characteristics, are used as produced, and,during installation on board, require no adjustments or modifications which could adverselyaffect the NOx emissions.
Chapter 4.1.3 reads as follows:The engine group concept may be applied to a smaller series of engines produced for similarengine application and which require minor adjustments and modifications during installationor in service on board. These engines are normally large power engines for main propulsion.
Chapter 4.1.4 reads as follows:Initially the engine manufacturer may, at its discretion, determine whether engines should becovered by the engine family or engine group concept. In general, the type of application shallbe based on whether the engines will be modified, and to what extent, after testing on a test-bed.
Interpretation:
The Engine Family concept shall be interpreted as applicable to mass produced small boreengines (generally high speed) that may, for design purposes, include adjustable features but aregenerally dispatched with the intent that no ‘installation’ or ‘in service’ setting modificationsare undertaken.
For marine engine applications the Engine Group concept shall be interpreted as applicable toany engine intended for main propulsion or auxiliary duties, where adjustment and modificationfollowing installation (and through the service life of the engine) is considered routine.
For application of the Engine Family or Engine Group concepts it shall be interpreted thatengines within an Engine Family may have different cylinder bore and stroke dimensions(within the defined limits - see Chapter 4.3.8.2.3) and that engines within an Engine Groupconcept effectively have identical bore and stroke dimensions as a result of only one of theparameters defined under Chapter 4.4.5.2 being permitted to vary within the defined enginegroup.
An Onboard NOx Verification Procedure shall be included within the Technical Files of allengines irrespective of whether they are included within an Engine Family or Engine Group.

Chapter 4.3 Application of the engine family concept
Chapter 4.3.1 reads as follows:
The engine family concept provides the possibility of reducing the number of engines whichmust be submitted for approval testing, while providing safeguards that all engines within thefamily comply with the approval requirements. In the engine family concept, engines withsimilar emission characteristics and design are represented by a parent engine within the family.
Chapter 4.4 Application of the engine group concept
Chapter 4.4.1 reads as follows:
These are engines used primarily for main propulsion. They normally require adjustment ormodification to suit the on-board operating conditions but which should not result in NOxemissions exceeding the limits in 3.1 of this Code.
Interpretation:
For application of these sections it shall be interpreted that where the measured performance ofa Member Engine to an Engine Family or Engine Group is fundamental to the verification thatthat member engine is operating within the parameters defined by the approved engine familyor group, then that performance data (emissions, engine performance, ambient conditions) andother necessary data shall have been obtained in accordance with NOx Technical Code Chapter5.

This requirement maynot be necessary for families established for the purpose of engine modifications on board afteran EIAPP Certificate has been issued.
Chapter 4.4 Certification of an engine groupChapter 4.4.8 Certification of an engine groupChapter 4.4.8 reads as follows:The requirements of 4.3.10 apply mutatis mutandis to this section.
Interpretation:For application of these sections it shall be interpreted that the conformity of productionscheme would need to demonstrate the following aspects:
(a) The connection between the NOx critical component part / ID numbers as proposed for the Engine Family or Engine Group and the drawing numbers (and revision status if applicable) defining those components.
(b) The means by which the Administration will be able, at the time of a survey, to verify that the drawings used for the production of the NOx critical components correspond to the drawings established as defining the Engine Family or Engine Group.
(c) Drawing revision control arrangements. Where it is proposed by a manufacturer that revisions to the NOx critical component drawings defining an Engine Family or Engine Group may be undertaken through the life of an engine, then the conformity of production scheme would need to demonstrate the procedures to be adopted to cover the cases where revisions (a) will not, or (b) may affect NOx emissions. These procedures shall cover drawing number allocation, effect on the identification markings on the NOxcritical components and the provision for providing the revised drawings to the Administration responsible for the original Engine Family or Engine Group approval.
Where these revisions may affect the NOx emissions the means to be adopted to assess / verify performance against the parent engine performance are to be stated together with the subsequent actions to be taken regarding advising the Administration and, where necessary, the declaration of a new Parent Engine prior to the introduction of those modifications into service.
(d) The implemented procedures that ensure any NOx critical component spare parts supplied to a certified engine will be identified as given in the approved Technical File and hence will be produced in accordance with the drawings as defining the Engine Family or Engine Group.
It would also be interpreted that all items (a) – (d) are applicable to Engine Family, EngineGroup and single engines.

Chapter 4.3.9.1 reads as follows:
The method of selection of the parent engine for NOx measurement shall be agreed to andapproved by the Administration. The method shall be based upon selecting an engine whichincorporates engine features and characteristics which, from experience, are known to producethe highest NOx emissions expressed in grams per kilowatt hour (g/kWh). This requiresdetailed knowledge of the engines within the family. Under certain circumstances, theAdministration may conclude that the worst case NOx emission rate of the family can best becharacterised by testing a second engine. Thus, the Administration may select an additionalengine for test based upon features which indicate that it may have the highest NOx emissionlevels of the engines within that family. If engines within the family incorporate other variablefeatures which could be considered to affect NOx emissions, these features must also beidentified and taken into account in the selection of the parent engine.
Chapter 4.4.7 Guidelines for the selection of the parent engine of an engine group
Chapter 4.4.7 reads as follows:
The selection of the parent engine shall be in accordance with the criteria in 4.3.9, asapplicable. It is not always possible to select a parent engine from small-volume productionengines in the same way as the mass-produced engines (engine family). The first engineordered may be registered as the parent engine. The method used to select the parent engine torepresent the engine group shall be agreed to and approved by the Administration.
Interpretation:
For application of these sections it shall be interpreted that where a Parent Engine (e.g. largebore 2-stroke engine) cannot be adjusted (e.g. maximum pressure, compression pressure,exhaust back pressure, charge air temperature) to the defined reference or maximum toleranceconditions at the test bed the measured NOx emission values shall be corrected to the definedreference and maximum tolerance conditions on the basis of sensitivity tests. This correctionshall be approved by the Administration. The resulting corrected average weighted NOxemission value is to be stated under 1.15 of the EIAPP Certificate.

The following criteria for selecting the parent engine for NOx emission control shall beconsidered, but the selection process must take into account the combination of basiccharacteristics in the engine specification:
.1 main selection criteria
- higher fuel delivery rate
.2 supplementary selection criteria
- higher mean effective pressure
- higher maximum cylinder peak pressure
- higher charge air/ignition pressure ratio
- dp/d�, the lower slope of the combustion curve
- higher charge air pressure
- higher charge air temperature
Interpretation:
For application of this section the term “main selection criteria” shall be interpreted as apossible selection criterion if no knowledge about the emission behavior of an Engine Familyor Engine Group is available. In all cases the final selection criteria for the Parent Engine is thehighest resulting average weighted NOx emission, at the applicable test cycle, according tosection 4.3.9.1.

Generally, if the parameters required by 4.4.5.2 are not common to all engines within aprospective engine group, then those engines may not be considered as an engine group.However, an engine group may be accepted if only one of those parameters or specifications isnot common for all of the engines within a prospective engine group provided the enginemanufacturer or the shipowner can, within the technical file, prove to the Administration thatsuch a transgression of that one parameter or specification would still result in all engineswithin the engine group complying with the NOx emission limits.
Interpretation:
For application of these sections it shall be interpreted that rated power per cylinder at ratedspeed is one parameter. Derating and uprating, in terms of power per cylinder and rated speed,outside the approved power or speed ranges shall be interpreted as deviations according tochapter 4.4.5.3.

Chapter 5.2 Test conditions
Chapter 5.2.2.2 reads as follows:
All engines when equipped as intended for installation on board ships must be capable ofoperating within the allowable NOx emission levels of regulation 13 (3) of Annex VI at anambient seawater temperature of 25OC.*
* 25OC seawater temperature is the reference ambient condition to comply with the NOx limits.An additional temperature increase due to heat exchangers installed on board, e.g., for the low-temperature cooling water system, shall be taken into consideration.
Interpretation:
For application of this section it shall be interpreted that the 25OC seawater temperature definesan ambient reference value for which compliance with the NOx emission limits as defined byregulation 13 (3) must be demonstrated (tested or calculated with TSC Ref specified by themanufacturer).
The application of this reference primary coolant value shall be considered in accordance withthe charge air cooling arrangement applicable to the individual installation as follows:
(a) Direct seawater cooling to engine charge air coolers. Compliance with the NOx limits shall be demonstrated (or otherwise justified) with a charge air / scavenge air cooler coolant inlet temperature of 25OC.
(b) Intermediate ‘freshwater’ cooling to engine charge air coolers. Compliance with the NOxlimits shall be demonstrated (or otherwise justified) with the charge air / scavenge air cooling system operating with the highest allowable in service coolant inlet temperature regime comparable with an ambient seawater temperature of 25OC.
Demonstration of compliance at a Parent Engine test for a direct seawater cooled system,as given by (a) above, does not demonstrate compliance in accordance with the higher charge air temperature regime inherent with an intermediate ‘freshwater’ cooling arrangement as given under (b).
(c) For those installations incorporating no seawater cooling, either direct or indirect, to the charge air coolers e.g. radiator cooled ‘freshwater’ systems, air / air charge air coolers, then it shall be interpreted that compliance with the NOx limits must be demonstrated with the engine and charge air cooling systems operating “as intended for installation on board”.

The sampling probes for the gaseous emissions shall be fitted at least 0.5m or 3 times thediameter of the exhaust pipe – whichever is the larger – upstream of the exit of the exhaust gassystem, as far as practicable, but sufficiently close to the engine so as to ensure an exhaust gastemperature of at least 343K (70oC) at the probe.
Interpretation:
Recognising that successful measurement of gaseous HC requires an exhaust gas temperatureof at least 190oC, the 70oC requirement shall be interpreted as a minimum exhaust gastemperature requirement at the NOx sampling probe where that differs from the HC samplingprobe. In the latter case a minimum temperature of 463 K (190oC) at the probe is required.
With regard to the HC sampling system, a heated filter and sampling line shall be providedbetween the sampling probe and the HC analyser. The filter shall extract any solid particlesfrom the gas sample before the analyser and be changed as necessary. The temperature of theheated filter and the wall temperature of the heated line shall be 463 K (190oC) ± 10 K.

Chapter 5.9.3.2 reads as follows:
In the case of a multi-cylinder engine with a branched exhaust manifold, the inlet of the probeshall be located sufficiently far downstream so as to ensure that the sample is representative ofthe average exhaust emission from all cylinders. In multi-cylinder engines having distinctgroups of manifolds, such as in a “Vee” engine configuration, it is permissible to acquire asample from each group individually and calculate an average exhaust emission. Other methodswhich have been shown to correlate with the above methods may be used. For exhaust emissioncalculation, the total exhaust mass flow must be used.
Interpretation:
In the case of multiple turbocharger arrangements it shall be interpreted that where it is notpossible to sample the exhaust gas from a position after where the individual turbochargertailpipes have combined into a single duct then the exhaust gas must be sampled downstream ofeach turbocharger and analysed. The individual measurement readings shall be averaged asnecessary to provide the emission concentrations which are representative of the emissionsfrom all cylinders.

Monitoring of combustion flue gas outlet temperature shall be required at all times andwaste shall not be fed into a continuous-feed shipboard incinerator when thetemperature is below the minimum allowed temperature of 850°C. For batch-loadedshipboard incinerators, the unit shall be designed so that the temperature in thecombustion chamber shall reach 600°C within five minutes after start-up.
Interpretation
The minimum combustion chamber flue gas outlet temperature of 850°C is equallyapplicable to continuous-feed and batch-loaded shipboard incinerators[1]. Monitoring ofthe combustion flue gas outlet temperature shall be required at all times for both typesof incinerators.
[1] Refer to MEPC/Circ.473 for applicable incinerators.

Regulation 22(5), Annex I of MARPOL 73/78as amended by resolution MEPC.117(52)
Regulation 22, Pump-room bottom protection
Regulation 22 (entering into force on 1 January 2007) reads:
“ 1. This regulation applies to oil tankers of 5,000 tonnes deadweight and above constructedon or after 1 January 2007.
2. The pump-room shall be provided with a double bottom such that at any cross-section thedepth of each double bottom tank or space shall be such that the distance h between thebottom of the pump-room and the ship’s base line measured at right angles to the ship’s baseline is not less than specified below:
h = B/15(m) orh = 2 m, whichever is the lesser.
The minimum value of h = 1 m.
3. In case of pump rooms whose bottom plate is located above the base line by at least theminimum height required in paragraph 2 above (e.g. gondola stern designs), there will be noneed for a double bottom construction in way of the pump-room.
4. Ballast pumps shall be provided with suitable arrangements to ensure efficient suction fromdouble bottom tanks.
5. Notwithstanding the provisions of paragraphs 2 and 3 above, where the flooding of thepump room would not render the ballast or cargo pumping system inoperative, a doublebottom need not be fitted.”.
Interpretation
1. The term “pump-room” means a cargo pump room. Ballast piping is permitted to be locatedwithin the pump-room double bottom provided any damage to that piping does not render theship’s pumps located in the “pump room” ineffective.

Annex I of MARPOL 73/78 Regulation 12A asamended by Resolution MEPC.141(54)Regulation 12A.9, as amended by Resolution MEPC.141(54), reads:
“Lines of oil fuel piping located at a distance from the ship’s bottom of less than h, asdefined in paragraph 6, or from the ship’s side less than w, as defined in paragraphs 7 and 8shall be fitted with valves or similar closing devices within or immediately adjacent to the oilfuel tank. These valves shall be capable of being brought into operation from a readilyaccessible enclosed space the location of which is accessible from the navigation bridge orpropulsion machinery control position without traversing exposed freeboard or superstructuredecks.The valves shall close in case of remote control system failure (fail in a closed position) andshall be kept closed at sea at any time when the tank contains oil fuel except that they maybe opened during oil fuel transfer operations.”
Regulation 12A.10, as amended by Resolution MEPC.141(54), reads:
“Suction wells in oil fuel tanks may protrude into the double bottom below the boundary linedefined by the distance h provided that such wells are as small as practicable and thedistance between the well bottom and the bottom shell plating is not less than 0.5 h.”
Interpretation:
1. Valves for oil fuel tanks located in accordance with the provisions of paragraphs 6, 7and 8 of MARPOL regulation I/12A may be treated in a manner similar to the treatment ofsuction wells as per MARPOL regulation I/12A.10 and therefore arranged at a distance fromthe ship’s bottom of not less than h/2 (see the figure below).
2. Valves for tanks which are permitted to be located at a distance from the ship’sbottom or side at a distance less than h or w, respectively, in accordance with the accidentaloil fuel outflow performance standard of MARPOL regulation I/12A.11 may be arranged at thedistance less than h or w, respectively.
3. Fuel tank air escape pipes and overflow pipes are not considered as part of‘lines of fuel oil piping” and therefore may be located at a distance from the ship’s side of lessthan w.
Note:This Unified Interpretation is to be applied by all Members and Associates on ships deliveredon or after 1 August 2010 as defined in MARPOL regulation I/28.9.

Volatile Organic Compounds (VOCs)Management Plan
MARPOL VI, Regulation 15.6 and 15.7
6 A tanker carrying crude oil shall have on board and implement a VOC ManagementPlan approved by the Administration. Such a plan shall be prepared taking into account theguidelines developed by the Organization. The plan shall be specific to each ship and shall atleast:
.1 provide written procedures for minimizing VOC emissions during the loading,sea passage and discharge of cargo;
.2 give consideration to the additional VOC generated by crude oil washing;
.3 identify a person responsible for implementing the plan; and
.4 for ships on international voyages, be written in the working language of themaster and officers and, if the working language of the master and officers isnot English, French, or Spanish, include a translation into one of theselanguages.
7 This regulation shall also apply to gas carriers only if the type of loading andcontainment systems allow safe retention of non-methane VOCs on board or their safe returnashore.
Interpretation
The requirement for a VOC Management Plan applies only to a tanker carrying crude oil.
Note:
1. This UI is to be uniformly implemented by IACS Societies from 1 August 2010.

“Time of the Replacement or Addition”for the Applicable Tier StandardFor the Supplement to the IAPP Certificate
MARPOL Annex VI Regulation
Reg 13.2.2 For a major conversion involving the replacement of a marine diesel engine with anon-identical marine diesel engine or the installation of an additional marine diesel engine,the standards in this regulation in force at the time of the replacement or addition of theengine shall apply.
Interpretation
The "time of the replacement or addition" of the engine is to be taken as the date of:
a. the contractual delivery date of the engine to the ship*; or
b. in the absence of a contractual delivery date, the actual delivery date of the engine tothe ship*, provided that the date is confirmed by a delivery receipt; or
c. in the event the engine is fitted onboard and tested for its intended purpose on or after 1July 2016, the actual date that the engine is tested onboard for its intended purpose appliesin determining the standards in this regulation in force at the time of the replacement oraddition of the engine.
The date in a), b) or c), provided the conditions associated with those dates apply, is the“Date of major conversion – According to Reg. 13.2.2” to be entered in the IAPPCSupplement.In this case the “Date of installation”, which applies only for identical replacement engines,shall be filled in with “N.A.”
If the engine is not tested before 1 July 2016 due to unforeseen circumstances beyond thecontrol of the ship owner, then the provisions of “unforeseen delay in delivery” may beconsidered by the Administration in a manner similar to MARPOL Annex I UI4.
_________
Footnote:
*) The engine is to be fitted onboard and tested for its intended purpose before 1 July 2016.
Note
1. This UI is to be uniformly applied by IACS Societies to IAPP Certificates which arenewly issued on or after 1 January 2013. Existing IAPP Certificates onboard are validuntil their expiry.

.2. shall have no discharge connections to the bilge system, oily bilge waterholding tank(s), tank top or oily water separators except that the tank(s) may befitted with drains, with manually operated self-closing valves and arrangements forsubsequent visual monitoring of the settled water, that lead to an oily bilge waterholding tank or bilge well, or an alternative arrangement, provided such arrangementdoes not connect directly to the bilge piping system.
MARPOL 73/78 Annex I Unified Interpretation to regulation 12.2.2 introduced byMEPC.1/Circ.753
2 There should be no interconnections between the sludge tank discharge piping andbilge-water piping other than possible common piping leading to the standard dischargeconnection referred to in regulation 13.
Interpretation
Screw-down non-return valves arranged in lines connecting to common piping leading to thestandard discharge connection required by regulation 13, to prevent sludge from dischargingto the bilge system, oily bilge water holding tank(s), tank top or oily water separators, providea means equivalent to an arrangement that has “no interconnection” or “no dischargeconnections” as so specified in regulation 12.2 and Unified Interpretation thereto.
It is understood that the common piping may serve only one purpose and that is to connectthe discharge lines of the bilge and sludge pumps to the standard discharge connectionreferred to in regulation 13, or any other approved means of disposal.
NOTE
1. This Unified Interpretation is to be uniformly implemented by IACS Societies from1 July 2012.

Date of Delivery under SOLAS and MARPOL Conventions Under certain provisions of the SOLAS and MARPOL Conventions, the application of regulations to a new ship is governed by the dates:
1. for which the building contract is placed on or after dd/mm/yyyy; or
2. in the absence of a building contract, the keel of which is laid or which is at a similar stage of construction on or after dd/mm/yyyy; or
3. the delivery of which is on or after dd/mm/yyyy.
Interpretation For the purpose of determining the application of mandatory requirements of the SOLAS and MARPOL Conventions to a new ship, the date of “delivery" means the completion date (day, month and year) of the survey on which the certificate is based (i.e. the initial survey before the ship is put into service and certificate issued for the first time) as entered on the relevant statutory certificates. Note: This UI is to be uniformly implemented by IACS Societies from 28 June 2012.

Supplement to the International Air Pollution Prevention (IAPP) Certificate – Section 2.3 MARPOL Annex VI, Regulation 8 “The International Air Pollution Prevention Certificate shall be drawn up in a form corresponding to the model given in appendix I to this Annex and shall be at least in English, French or Spanish. If an official language of the issuing country is also used, this shall prevail in case of a dispute or discrepancy.” Revised form of Supplement to the IAPP Certificate as per MEPC.194(61)
Interpretation Section 2.3 of the Supplement ("as documented by bunker delivery notes") allows for an "x" to be entered in advance of the dates indicated in all of the relevant check boxes recognizing that the bunker delivery notes, required to be retained on board for a minimum period of three years, provide the subsequent means to check that a ship is actually operating in a manner consistent with the intent as given in section 2.3.
Note: This UI is to be uniformly implemented by IACS Societies not later than the first IAPP renewal survey carried on/after 1 January 2013. End of

Surveys and certification relating to the Ship Energy Efficiency Management Plan (SEEMP) (MARPOL Annex VI Regulation 5.4.4) Regulation 5.4 as amended by Resolution MEPC.203(62) reads: 4 Ships to which Chapter 4 applies shall also be subject to the surveys specified below, taking into account Guidelines adopted by the Organization1: .4 For existing ships, the verification of the requirement to have a SEEMP on board
according to regulation 22 shall take place at the first intermediate or renewal survey identified in paragraph 1 of this regulation, whichever is the first, on or after 1 January 2013
Regulation 6.4 as amended by Resolution MEPC.203(62) reads: 4 An International Energy Efficiency Certificate for the ship shall be issued after a survey in accordance with the provisions of regulation 5.4 to any ship of 400 gross tonnage and above before that ship may engage in voyages to ports or offshore terminals under the jurisdiction of other Parties. Interpretation 1. The International Energy Efficiency Certificate (IEEC) shall be issued for both new and
existing ships. 2. For existing ships a Ship Energy Efficiency Management Plan (SEEMP) required in
accordance with Regulation 22, shall be verified onboard according to Regulation 5.4.4, and an IEEC shall be issued, not later than the first Intermediate or Renewal MARPOL Annex VI Chapter 2 survey, whichever is the sooner, on or after 1 January 2013, i.e. a survey connected to a intermediate/renewal survey of the IAPP Certificate.
3. The Intermediate or Renewal survey referenced in 2. relates solely to the timing for the
verification of the SEEMP onboard, i.e. these IAPPC survey windows will also become the IEEC initial survey date for existing ships. The SEEMP is however a survey item solely under the new MARPOL Annex VI Chapter 4, and is not a survey item relating to IAPPC surveys.
4. In the event that the SEEMP is not found onboard during the first intermediate/renewal
survey of the IAPP Certificate on or after 1 January 2013, then the RO should seek the advice of the Administration concerning the issuance of an IEEC and be guided accordingly. However, the validity of the IAPP Certificate is not impacted by the lack of a SEEMP as the SEEMP is a survey item solely under the new MARPOL Annex VI, Chapter 4, and not under the IAPPC surveys.

Identical Replacement Engines(MARPOL Annex VI Regulation 13)
Regulation
MARPOL Annex VI Regulation 13
13.1.1.2 each marine diesel engine with a power output of more than 130 kW whichundergoes a major conversion on or after 1 January 2000 except when demonstrated to thesatisfaction of the Administration that such engine is an identical replacement to the enginewhich it is replacing and is otherwise not covered under paragraph 1.1.1 of this regulation.
13.2.2 For a major conversion involving the replacement of a marine diesel engine with anon-identical marine diesel engine or the installation of an additional marine diesel engine,the standards in this regulation in force at the time of the replacement or addition of theengine shall apply. …...”
Interpretation
In regulation 13.1.1.2 the term “identical” (and hence, by application of the converse, inregulation 13.2.2 the term “non-identical”) as applied to engines under Regulation 13 is to betaken as:
An ‘identical engine’ is, as compared to the engine being replaced*, an engine which is of thesame:
design and model;
rated power;
rated speed;
use;
number of cylinders;
fuel system type (including, if applicable, injection control software); and
(a) for engines without EIAPP certification, have the same NOx critical components and settings**; or
(b) for engines with EIAPP certification, belonging to the same Engine Group / Engine Family.
NOTE:
1. This Unified Interpretation is to be uniformly implemented by IACS Societies for“.. a time of the replacement ..” of an engine, as interpreted by UI MPC 98, occurring on or after 1 January 2014.

* In those instances where the replaced engine will not be available to be directly comparedwith the replacing engine at the time of updating the Supplement to the IAPP Certificatereflecting that engine change it is to be ensured that the necessary records in respect of thereplaced engine are available in order that it can be confirmed that the replacing enginerepresents “an identical engine”.
** For engines without EIAPP Certification there will not be the defining NOx criticalcomponent markings or setting values as usually given in the approved Technical File.Consequently in these instances the assessment of ‘... same NOx critical components andsettings...’ shall be established on the basis that the following components and settings arethe same:
Fuel system
(a) Fuel pump model and injection timing(b) Injection nozzle model
Charge air
(a) Configuration and, if applicable, turbocharger model and auxiliary blowerspecification
(b) Cooling medium (seawater / freshwater)
