19.5 Engine coupling

Figure 19.3: Engine coupling, fitted bolt arrangement

WARNING The illustrations above and below do not necessarily represent the actual configuration or the stage of development, nor the type of your engine. In order to have all the relevant and prevailing information available, please consult the drawings in the section "Drawings" at the end of present chapter.

19.5.1 Fitting of coupling boltsDrilling and reaming of the engine and shaft couplings is to be carried out using a computer controlled drilling machine or an accurately centred jig. Great care is to be taken in matching and machining mating flanges together. Fitted bolt hole tolerances are to be H7 and fitted bolts are to be available for inserting in the holes on completion of reaming. Each fitted bolt is to be stamped with its position in the coupling, with the same mark stamped adjacent to the hole. In the event of a pitch circle error leading to a misalignment of bolt holes, the situation has to be remedied by applying joint cylindrical reaming to an oversize hole and fitting an individually machined fitted bolt. Fitted bolts are to locate with a slight interference fit, but not requiring heavy hammer blows. If there is any doubt that a fitted bolt is too slack or too tight, refer to the classification society surveyor and a representative of the engine builder.

Figure 19.4: Details of coupling bolt and nut

When tightening the coupling bolts it is essential to work methodically, taking up the threads on opposite bolts to hand-tight, followed by sequential torque tightening.

19-124

Version a1



Mark each bolt head in turn, 1, 2, 3, etc., and tighten opposite nuts in turn to an angle of 55, making sure the bolt head is securely held and unable to rotate with the nut. Castellated nuts are to be locked according to the requirements of class with either locking wires or split pins. Use feeler gauges during the tightening process to ensure that the coupling faces are properly mated with no clearance.

19.6 Engine earthingElectric current flows when a potential difference exists between two materials. The creation of a potential difference is associated with thermoelectric by the application of heat, tribo-electric between interactive surfaces, electrochemical when an electrolytic solution exists, and electromagnetic induction when a conducting material passes through a magnetic field. Tracking or leakage currents are created in machinery by any of the above means and, if they are not adequately directed to earth, can lead to component failures or in some cases result in fires and interference with control and monitoring instrumentation.

19.6.1 Preventive actionUsing earthing brushes in contact with slip-rings and bonding the chassis by braided copper wire are common ways of protecting electric machines. Where operating loads and voltages are comparatively low, then the supply is isolated from the machine by an isolating transformer, often with handheld power tools. The build specification dictates the earthing procedure to be followed and the classification society is to approve the final installation. On vessels with star-wound alternators the neutral is considered to be earth, and electrical devices are protected by automatic fuses. Ensure that instrument wiring meets the building and classification society specifications and that it is shielded and isolated to prevent induced signal errors and short circuits. In certain cases large items of machinery are isolated from their foundations, and couplings are isolated to prevent current flow, e.g. when electric motors are connected to a common gear box. Retrospective fitting of earthing devices is not uncommon, but due consideration is to be given at the design stage to adequate shielding of control equipment and earthing protection where tracking and leakage currents are expected. Magnetic induction and polarisation are to be avoided and degaussing equipment incorporated if there is likely to be a problem.

19.6.2 Main shaft earthing systemFigures 19.6 and 19.5 show a typical shaft earthing system. The slip-ring (1) is supplied as matched halves to suit the shaft and secured by two tension bands (2) using clamps (12). The slip-ring mating faces are finished flush and butt jointed with solder. The brushes (4) are housed in the twin holder (3) clamped to a stainless steel spindle (6) and there is a monitoring brush (11) in a single holder (10) clamped to an insulated spindle (9). Both spindles are attached to the mounting bracket (8). The electric cables are connected as shown in figure 19.7 with the optional voltmeter. This instrument is at the discretion of the owner but it is useful to observe that the potential to earth does not rise above 100 mV. Different combinations of conducting material are available for the construction of the slip-rings. However, alloys with a high silver content are found to be efficient and hard wearing. Wrtsil Switzerland Ltd. recommends installing a shaft earthing device on the intermediate shafting as illustrated in figure 19.5.

19.7 Engine staysShip vibrations and engine rocking caused by the engine behaviour (as described in chapter 6. Engine Dynamics) are reduced by fitting lateral and longitudinal and stays.

19.7.1 Stays arrangementInstallation of lateral stays - hydraulic and friction types Fitting of lateral stays between the upper platform level and the hull reduces transmitted vibration. Two types of stays can be considered: Hydraulic stays: ................. two by two installed on the exhaust and on the fuel side of the engine. Friction stays: .................... installed on the engine exhaust side. Table Countermeasures for lateral and longitudinal rocking indicates in which cases the installation of lateral stays is to be considered.

FunctionTransverse vibrations of the engine cause rapid pressure fluctuations in the hydraulic cylinder. Thereby the unit behaves like a strong spring. By using the throttling valve III (page 3), the spring rate can be adjusted such that the rapid pressure fluctuations are practically filtered off and do not continue into the hydro accumulator. The hydraulic cylinder nevertheless adjusts itself to the slow deformations of the ship's hull.

4.

InstallationThe hydraulic cylinders are to be bolted to the reinforced attachment points on the ship structure. The adjustments screws are welded on the engine at position shown on the relevant arrangement drawing from the engine builder. Stay length "L" shown on page 2 is to be determined and the diameter "D" taken from the table or from the arrangement drawing.

5.

CommissioningCommissioning of the hydraulic cylinders should be carried out shortly before the sea trial as follows:

5.1.

The stay is to be fitted between the hydraulic cylinder and the adjusting screw on engine side and secured against dropping. The adjusting screw is to be set as shown on page 2 (axially: piston face and indicator pin to be on same plane; radially: pin and holes in line). Set bolt pos. I to be secured. The hydro accumulator will be delivered pre-pressurised to 10 bar. The pressure is to be raised to the figure shown on page 7 with the help of the tester pressurizer (see page 9).

5.2.

5.3.

Plug pos. II is to be removed for filling of the hydraulic oil and the flexible hose connected to the hand pump. Throttling valve pos. III and filling valve pos. IV must be open (throttling valve switched to mark "1") as well as vent screws pos. V on the hydro accumulator and pos. IV on the hydraulic cylinder. Hydraulic oil to be pumped slowly into the hydr. cylinder (oil to be warmed when engine room is cold). After perfect venting, first close vent screw pos. IV on the hydr. cylinder and then vent screw pos. V on the hydro accumulator. The 4 hydr. cylinders must then be pumped up to service pressure as follows:

5.4.1.

On cylinder A the oil pressure is to be raised to half the nominal pressure shown on page 7. (Pressure to be checked at the built on pressure gauge below the hydro accumulator). Filling valve pos. IV is to be closed and the hand pump disconnected. On cylinder B the same preparatory work can be carried out, however, the pressure can be raised to 10 bar above the nominal pressure. Filling valve pos. IV is to be closed and the plug (II) fitted. The hand pump is to be reconnected to cylinder A and the pressure increased to 10 bar above the nominal pressure. Filling valve pos. IV is to be closed and the plug (II) fitted. The procedure for cylinders C and D is the same as for cylinders A and B. After several hours, all hydraulic cylinders must be vented carefully at valves V and VI so as not to loose too much pressure. It must not sink below the nominal value.

5.4.2.

5.4.3.

5.4.4. 5.4.5.

5.5.

The throttling valve pos. III is to be adjusted to mark "A" and secured on all cylinders. Mark "B" is used for reduced stiffness. At Mark "1" the function is practically ineffective. Attention The throttling valve pos. III must never be closed (Mark "0") in service because in this position the hydraulic piston cannot adjust itself to the movement of the ship's hull.

6.

Sea trialThe hydraulic cylinders must be checked frequently for oil pressure and general soundness.

6.1.

At the end of the sea trial the following must be checked: - "0" position of the piston according to page 2 - pressure to be the nominal value as shown on page 7. If the pressure is too high it can be corrected with careful opening of the vent screw pos. V. Where the pressure is too low, it has to raised with the hand pump.

7.

Check when loading the ship fully for the first timeThe position of the piston relative to the cylinder is to be checked when the ship is fully laden. Should it occur that the piston is almost touching the bottom of the cylinder (this situation must not be allowed to occur, but it will happen when the piston is 15 mm on the inside of the "0" position) then the hydraulic lateral fixation device is to be shortened by about 7 mm with the adjusting screw pos. VII.

8.

Regular checksThe oil pressures on the pressure gauges of the hydraulic cylinders are to be compared with each other at regular intervals. (The shown oil pressure may not be identical with the nominal pressure, because it varies according to the loading of the ship). If one of the cylinders shows a considerably lower pressure, which could be caused by a leaking seal, the opposite hydraulic cylinder must be released of its pressure until the leaking seal has been replaced. Afterwards both cylinders are to be put into service as mentioned under commissioning.

The bladder, enclosed in the accumulator body is pre-pressurised by means of an inert gas (nitrogen), capable of great compression, to a pressure determined by the needs of the work to be done. During this pressurising operation, the bladder expands, progressively approaches the lower part of the accumulator, and presses against its sides, so occupying the entire volume of the chamber (1). When the circuit pressure generator causes the liquid to penetrate into the shell of the accumulator (2) the gas enclosed in the bladder is compressed and increases the pressure. The process comes to an end when the pressure of the liquid and of the gas reach equilibrium (3). In the reverse process, the return commences when the resisting pressure of the liquids is less than the pressure of the gas in the bladder. The lateral deformation of the latter in three lobes, forming a shamrock shape with three promontories excludes rubbing and inertia, and enables an efficiency of nearly 100% to be attained.

INSTALLATION AND USESetting up (see figure on page 11) Before any pre-charge checks and/or nitrogen pressurizing, the hydraulic fluid of the hydro-pneumatic accumulator must be discharged. Accumulator with hydraulic valve: - Completely screw the lobed hand-wheel (no. 6) outwards - Unscrew the protective cap(s) of the accumulator gas inlet valve. - Screw pressurizer with intermediary no. 23 or 26 (+ connector no. 30 for Schrder valves) onto the hydraulic valve. Move the manometer into a convenient position for reading, and tighten the intermediary (no. 5) by hand. - Check that the release valve is closed. (close the lobed hand-wheel no. 18 in an clockwise direction). Checking the charge pressure: - Turn the lobed hand-wheel (no. 6) in an anti-clockwise direction. This causes the gas inlet valve or allen screw to open. The pressure may now be read on the manometer. Reducing the charge pressure: - Rotate the lobed hand-wheel (no. 18) of the release valve slowly in an anti-clockwise direction. The nitrogen is released into the surrounding air. Pressurizing/raising the charge pressure: - Connect the charging hose: one end to the return valve (no. 7) and the other to a standard nitrogen flask. - Open the stop valve on the nitrogen flask carefully. Allow the nitrogen to flow into the accumulator slowly, till the desired pre-charge pressure is reached. - Close the stop valve on the nitrogen flask. After 5-10 minutes (temperature stabilisation), check the charge pressure again and correct where necessary. Dismantling: - Turn the lobed hand-wheel (no. 6) back. - Screw the lobed hand-wheel (no. 18) outwards - Unscrew instrument. - Tighten screw valve with allen key SW6. - Check the gas inlet valve seal with a foam-forming substance. - Screw the protective cap(s) back on and tighten by hand. Caution: - Never use oxygen to inflate the accumulator. - Where the nitrogen flask pressure is higher than the permitted accumulator working pressure, a pressure limitation valve must be fitted.

Fitting instructions for engine stays (friction type)for lateral and longitudinal application

1. IntroductionLateral and longitudinal stays are installed where countermeasures for dynamic effects are to be taken (for indication refer to Marine Installation Manual, chapter E or to Engine Selection and Project Manual). For stay arrangement and details refer also to the relevant installation drawings of the corresponding design group 9715. It is vital that the stays are fitted correctly to ensure proper operation and to prolong lifetime of the components.

2. Description and functionAccording to WNS standard design two stays are fitted between the engine and the ship's hull. They transmit lateral or longitudinal forces from the engine body attachment (pos. 1) via the friction shims and the sheet metal girders (pos. 2) to the ships attachment (pos. 3). The clamping force of the two elastic bolts is adjusted so that during service the engines pulsating forces are transmitted to the ships hull. During loading and unloading however, the stay is able to adapt to deformations of the ships hull within its stroke. To reduce material stress in the stay itself and also in the attachment points hinge pins are provided to allow movements in both vertical and longitudinal direction.

For lateral application the stays are welded on the exhaust side just below the upper platform onto the scavenge air receiver box or in exceptional cases onto the turbocharger support. For longitudinal application they are welded at the engine free end onto the upper platform supports where special attachment plates are provided by the engine builder. For examples of stay arrangement see figures No. 2, 3 and 4. As the design of the elastic bolts is similar to that applied for the engine holding down studs, the same hydraulic tool (design group 9411-06) is used for pretensioning.

3. Fitting of the stays3.1 Starting conditions Before the stays are fitted, following conditions must be fulfilled: Ship afloat Engine aligned and chocked Engine coupled to intermediate shaft Engine holding down studs fully tightened Side stoppers fitted Engine preheated to starting condition Relevant installation drawings available Hydraulic tensioning device ready to use (engine builders tool kit, code-No. 94145) Note: When fitting the stays it is very important that the engine is preheated to starting condition. This is to reduce any possible misalignment of the stay due to engine thermal expansion between fitting and service condition. Excessive horizontal and vertical misalignment of the stay between the engines and the ships attachment point may restrict the stay function. It may even lead to buckling or cracking of the stay. For admissible tolerances refer to table 2. When positioning and fitting use crane to avoid overstress to the stay. 3.2 Sequence of operations 1.) Check whether the stays are completely and correctly assembled according to the relevant assembly drawing. Observe that the two elastic bolts are concentric with the holes of the attachment device (nominal position). The bolts are not tightened with the final hydraulic tensioning pressure but sufficiently so that no shifting within the stroke is possible when handling the stay.

2.) Check that there is no platform support, piping or else which could collide with the stay. In particular pay attention to the space requirements of the hydraulic tensioning device in order to allow proper tightening of the elastic bolts. 3.) Measure the actual stay length X and compare it to the effective clear width between the previously determined attachment points on engine and ship side. As foreseen in the design the stay length may, when assembled correctly, exceed the clear width slightly due to the over measure of the latch of the engine side attachment device (fig.1/pos.1 and fig.5). 4.) Shorten then the stay at the latch to the required length X while observing table 1 as a guideline. A tolerance of the stays length is allowed, however, ensure that the actual stay length X does not exceed the clear width by more than 5mm and that the gap is no more than 10mm. At the same time prepare the edges for welding. Note: During loading the ships hull is supposed to deform towards the ships centre line or engine side respectively. It is therefore preferable fitting a stay with a length just correct or rather too short than with an over length as an extra stroke in the relevant direction can be realised (see table 1). 5.) Make sure that the surfaces of the receiver box/platform support and the ship side attachment points are clean. Position the stay to the foreseen attachment points and compensate the a.m. possible deviation in length by loosening the elastic bolts and shifting the stay accordingly. After shifting retighten the bolts. 6.) Then align the stay in all planes within the given tolerances (see table 2) and fix it by spot welding starting on engine side. 7.) Before commencing the final welding, loosen the elastic bolts in order to avoid material stress due to thermal expansion. When welding, pay attention that no deviation in the stay alignment occurs. When fitting longitudinal stays after welding, overlapping parts of the latch may be cut off if required (see fig. 4). 8.) After welding, when all parts have cooled down make sure the stay is free of any tension. Retighten the elastic bolts by means of the tensioning device with the hydraulic pressure given in table 4.Engine side Ship side

4. Operational check and final adjustment4.1 During sea trial During service check whether relative movements between the ship side attachment device (fig.1/pos. 3) and the sheet metal girders (fig.1/pos. 2) occur. If this is the case, following might be the cause: Insufficient or incorrect tightening of the elastic bolts Dirty or damaged friction shims Material or quality of friction shims not according to WNS specification Incorrect assembly of the stays Incorrect fitting or alignment, i.e. welding 4.2 After sea trial After sea trial, when the engine and machinery space still are in hot condition, check whether measure M remained within the limits given in table 3 and check also whether the stays are still in line with the engine (horizontally and vertically). If not, it may help to loosen the elastic bolts. The sheet metal girders can then move within the clearance of the through holes of the ship side attachment device. Undesirable tension in the stay can release and possible misalignment may be compensated. At a latter stage, when the vessel has been loaded and unloaded, check whether displacement between engine and ship hull has taken place to make sure the stays work properly. Check also whether measure M remained within the limits given in table 3. If this is not the case, refer to the possible causes listed under 4.1. For maintenance repeat the above mentioned checks i.e. check the pretension of the bolts at intervals as foreseen for the maintenance of the engine holding down studs.

19.8 Fire protectionFires may develop in areas such as under-piston spaces and scavenge air receiver. The engine is fitted with a piping system which leads the fire extinguishing agent into the mentioned areas. Where fire protection is required, the final arrangement of the fire extinguishing system is to be submitted for approval to the relevant classification society.

19.8.1 Extinguishing agentsVarious extinguishing agents can be considered for fire fighting purposes. Their selection is made either by the shipbuilder or the shipowner in compliance with the rules of the classification society involved. Table gives the recommended quantity of 45 kg bottles of CO2 for each engine. Steam as an alternative fire extinguishing medium is permissible for the scavenge air spaces of the piston underside, but may cause corrosion if countermeasures are not taken immediately after its use. These countermeasures comprise: opening scavenge spaces and removing oil and carbon deposits drying all unpainted surfaces and applying rust protection (i.e. lubricating oil). NOTICE Steam is not suitable for fire extinguishing under-piston spaces, as this may result in damage to vital parts such as the crankshaft. If steam is used for the scavenge spaces at piston underside, a water trap is recommended to be installed at each entry to the engine and assurance obtained that steam shut-off valves are tight when not in use.

20. Engine Emissions


The International Maritime Organisation (IMO) is a specialized agency of the United Nations (UN), dealing with technical aspects of shipping. For more information see http://www.imo.org.

20.1 Exhaust gas emissions20.1.1 Establishment of emission limits for shipsIn 1973 an agreement on the International Convention for the Prevention of Pollution from ships was reached. It was modified in 1978 and is now known as MARPOL 73/78. The Annex VI to MARPOL 73/78, entered into force in 2005, contains regulations limiting or prohibiting certain types of emissions from ships, including limitations with respect to the allowed air pollution. Following the entry into force of the annex, a review process was started, resulting in an amended Annex IV, which was adopted by the IMO in October 2008 and entered into force in July 2010. This amended Annex IV includes provisions for the further development of the emissions regulations until 2020.

20.1.2 Regulation regarding NOx emissions of diesel enginesRegulation 13 of Annex IV specifies a limit for the nitrogen oxide (NOx) emissions of engines installed on ships, which has a direct implication on propulsion engine design. Depending on the rated speed of the engine and the date of keel-laying of the vessel, the weighted average NOx emission of that engine must not exceed the maximum allowable value as indicated by the respective curves in the following diagram.

Figure 20.1: Speed dependent maximum average NOx emissions by engines

Version a1

20-1



The rules and procedures for demonstrating and verifying compliance with this regulation are laid down in the NOx Technical Code, which is part of Annex VI and is largely based on the latest revision of ISO 8178.

20.1.3 Measures for compliance with the IMO regulationThe rating field is divided in two areas as shown in figure 20.2, and comprises the following measures: Low NOx Tuning In the upper part of the rating field the IMO regulation is fulfilled by the use of the Low NOx Tuning concept. Low NOx Tuning includes well tested measures, which lead to lowest disadvantage in engine costs and fuel consumption while maintaining the high reliability levels of pre-IMO tuned engines. Extended measures In the lower part of the rating field, fulfilling the IMO NOx regulation requires the application of extended measures. For further information please do not hesitate to contact one of our offices.

20.2 Engine noiseIt is necessary to protect the ships crew/passengers from the effects of machinery space noise. Therefore the scavenge air ducts and the exhaust duct system (both expansion joints of gas outlet and gas inlet of turbocharger) should be equipped with the standard insulation and the turbocharger with the standard intake silencer.

20.2.1 Engine surface sound pressure levelFigure 20.3 shows the average air borne noise level, measured at 1 m distance and at nominal MCR. Near the turbocharger (air intake), the maximum measured noise level will normally be about 3-5 dB(A) higher than the average noise level of the engine.

Figure 20.3: Engine sound pressure level at 1 m distance

Average values Lp in dB in comparison with the ISO NR-curves and overall average values LpA in dB(A), at nominal MCR under free field conditions.

20-3



20.2.2 Engine exhaust sound pressure level at funnel topThe sound pressure level from the engine exhaust gas system without boiler and silencer (given in figure 20.4) is related to: a distance of one metre from the edge of the exhaust gas pipe opening (uptake) an angle of 30 to the gas flow direction nominal MCR. Each doubling of the distances reduces the noise level by about 6 dB. Depending on the actual noise level allowed on the bridge wing - which is normally maximum 60-70 dB(A) - a simple flow silencer of the absorption type may be necessary and placed after the exhaust gas boiler. The silencer is dimensioned for a gas velocity of approximately 35 m/s with a pressure loss of approx. 2 mbar at specified MCR.

20.2.3 Engine structure borne noiseThe vibrational energy is propagated via engine structure, bedplate flanges and engine foundation to the ships structure, which starts to vibrate and thus emits noise. The sound pressure levels in the accommodations can be estimated with the aid of standard empirical formulas and the vibration velocity levels given in figure 20.5.

22. Spare Parts


IntroductionThis list is intended for single engined installation. In multi-engined installation the required spare parts are only necessary for one engine. Column IACS: Minimum spare parts recommended by the International Association of Classification Societies (IACS Rec. No. 26, 1990). Columns Additional parts: Spare parts recommended by WCH (Wrtsil Switzerland Ltd) for 10000 to 30000 hrs of operation which can be supplied at an extra price. These spare parts are in addition to the IACS ones. Each column is to be considered for itself, e.g. column 20000hrs already contains the parts listed in column 10000hrs. For following Classification Societies, IACS spare parts are considered as a requirement: CCS, GL, KR, NK, RS as a recommendation: ABS, BV, DNV, LR, PRS, RINA The statement made in brackets, for e.g. (2 per main bearing), is an information giving the number of parts per bearing or per cylinder, or per valve, etc., actually fitted in the engine. It is not necessarily the number of spare parts supplied. For details please refer to the appropriate Spare Parts Code Book.Supply
