Tank testing =
5.14.6(b) special periodical survey No 2 and subsequent special periodical
surveys (Age>5 years)
1)- all ballast tank boundaries
2)-all cargo tank bulkheads
Kindly refer to following Cargo /ballast tank testing procedure prior to
your vsl arrival Zhoushan Xinya S/Y, class surveyor might want to witness
the testing himself.(COT must be cleaned, carry out purging & gas free for
safe entry). C/O to record down this tank testing entry into logbook
accordingly. WBT to ballast 1P/S,3P/S & 5P/S.
A:Tank Testing:
For your information, Cargo tank testing carried out by the vessel’s crew
under the direction of the Master may be accepted by the Surveyor
provided the following conditions are complied with:
i) A tank testing procedure, specifying fill heights, for tanks
and bulkheads being tested, has been submitted by the owner and
reviewed by the Surveyor prior to the testing being carried out;
ii) There is no record of leakage, distortion or substantial
corrosion that would affect the structural integrity of the tank;
iii) The tank testing has been satisfactorily carried out within
special survey window not more than 3 months prior to the date of the
survey on which the overall or close up survey is completed;
iv) The satisfactory results of the testing is recorded in the
vessel’s logbook;
v) The internal and external condition of the tanks and
associated structure are found satisfactory by the Surveyor at the time of
the overall and close up survey.
B:1. As your vessel is scheduled for dry docking after last cargo
discharge. As such, the following are for your reference and preparation:
Deck side
(a) Prior arrival at anchorage de-slopping operation will be carried out),
ER waste oil, sludge, bilge water, etc must be transferred into Slop tank
before vessel arrives at anchorage. After de-slopping Slop tanks, please
wash and gas free the Slop tanks; and drain out all remaining oily water
from cargo suction/ cargo discharge/ Marpol/ COW piping system on
board. Cargo lines inside cargo pump should be drained/ stripped empty
(b) Cargo pump room tank top and bilge wells are to be kept free of oil
and bilges; as hot work may have to be carried in the cargo pump room
later during dry docking.
(c) Ship is to ensure that the following spaces are well-ventilated and
gas-freed
(i) Cargo tanks
(ii) Ballast tanks
(iii) Slop tanks
(iv) Cargo pump room void tank
(v) Other void tanks
(vi) Bunker tanks (< 50% LEL)
(vii) Cargo/ COW/ Marpol/ ODME pipelines.
(viii) Cargo manifolds (pipe flanges to be kept open for gas-check),
PLEASE ensure on deck pipelines & manifold lines are gas free! As hot
work might be performed in drydock, when removal of cargo valves for
overhaul.
Engine side
a. Special tools required to be used during dry dock are to be checked
and prepared, eg, M/E hydraulic tensioning jacks, hydraulic hoses,
connectors, etc. (Remarks: M/E hydraulic tensioning jacks should be tested
for oil leakages physically; up to the respective correct tensioning pressure
by mounting them onto the respective studs/ nuts. Spare hydraulic jack
seal and O rings must be checked available on board. Leaking jacks are to
be serviced and made ready for use.)
b. Before entry into shipyard, E/R tank top, waste oil tank, bilge holding
tank, sludge tank and bilge wells are to be empty/ kept low as far as
possible. If possible to avoid, any pumping and disposal of oil/ sludge/
bilge in shipyard.

Operation – A self propelled, steerable survey vehicle fitted with a long
range TV camera is used. To aid steering and to check for hull distortion, a
close up, high resolution TV color camera gives true picture of the state of
the coating and weld seams. In some cases, a 35 mm still camera is fitted.
An ultrasonic probe is provided to measure plate thickness and other
equipment included a depth meter and speed indicator. Power is supplied
and information relayed by means of an umbilical from the vehicle to the
survey boat.
Survey boat equipment-
Is usually housed in a console containing T.V monitors, plate thickness
print out, audio cassette recorder, video recorder and play back unit, diver
communication system, vehicle control system and associated
instrumentation.
The survey vehicle is taken to the starting datum by a diver. With the aid
of one of the TV monitors and using the shell expansion plan as a map, the
vehicle may be guided, from the control console, over the bottom and
sides of the hull, by following weld runs and by reference to other features,
such as inlets and tank plugs. Pictures and navigational information are
relayed back and video films recorded, along with plate thickness, giving
the surveyor an integrated picture of all the required and relevant
information. In addition to plate thickness, print out can be produced
and/or an audio recording.
The vehicle will also provide pictures of such items as stern frame, rudder,
propeller, bilge keels and hull openings. A diver may be used with hand
held camera. For closer inspection of these items and also for inspection of
the plating on the of bilge. It should be ensured during this operation, that
there is a 2 way communication between diver and attending surveyor.

Attn: Mr.
Dear Sir,
"MT PREMIER" LR NO 8802 ENHANCED SURVEY PROGRAMME (ESP)
1. The submitted ESP Survey Programme and ESP Planning
Questionnaire (planning document) for Special Survey, via our
Singapore office, has been examined and is noted as amended.
2. Please note that the requirements as per Part 1, Chapter 3,
Section 8, including Tables 3.7.3 and 3.7.6, for Special Survey I, of
The Rules and Regulations for the Classification of Ships are to be
complied with as applicable.
3. Please note that the approved service supplier is to be
nominated to perform thickness measurements and proposed
locations where the Special Survey and Docking Survey are to be
held noted. May we remind you that it is now a requirement that the
surveyor be onboard while the thickness measurements are taken, to
the extent necessary to control the process. Prior to the
commencement of any thickness measurements, a planning meeting
is to be held between the attending surveyor, the Owner's
representative and the Thickness Measurement Firm's representative
so as to ensure the safe and efficient execution of the surveys and
thickness measurements to be carried out on board.
4. The proposed locations and extent of Close-up survey and
thickness measurements of ESP Survey Programme is noted. Please
note that these nominated tanks, frame locations and strake
positions of structural areas are also to be proposed and agreed with
the attending surveyor. Arrangements should be in accordance with
Lloyd's Register's Rules and to the satisfaction of the attending
surveyor. May we remind you that for close-up survey the details of
structural components are to be within the close visual range of the
attending surveyor, i.e. normally within hand reach.
5. Where the result of the topside or bottom area assessments at
any/either of the transverse sections mentioned in Section 4 of
appendix 2 of the submitted Survey Programme are found to be
greater than 75% of the allowable limit, then additional transverse
sections are required to be measured forward and aft of 0.5L
amidships.
6. Kindly note that the thickness measurement report to be placed
onboard as part of the ESP documentation must reflect the final and
satisfactory condition of the ship. The report should be suitably
annotated where repairs/ renewals have been subsequently carried
out by either the thickness measurement company or attending
Surveyor.
7. Regarding your intention to carry out thickness measurements
at Yiu Dockyard, Shenzhen, China, it is concluded that arrangements
will be made for a surveyor to be in attendance through our local
offices. The proposed means of access for the carrying out Close-up
survey and thickness measurements noted. Please note that Rafts or
boats may be permitted for the survey of the under deck areas of
tanks or spaces, if the depth of the under deck web plating is 1, 5 m
or less. If the depth of the under deck web plating is greater than 1,5
m, then rafts or boats may be permitted only when the coating of the
under deck structure is in GOOD condition and there is no evidence
of wastage or if a permanent means of access is provided in each
bay to allow safe entry and exit. A permanent means of access is
considered to mean an access direct from the deck via a vertical
ladder and a small platform fitted approximately 2 m below the deck
in each bay. If neither of the above conditions are met, then staging
or another equivalent means is to be provided for the survey of the
under deck areas. (P1 Ch 3, Sect 1.6.8(c))
8. Please ensure all necessary structural plans are available
onboard to assist in the completion of the thickness measurement
report and are provided to the Thickness Measurement Company at
the earliest opportunity to assist in their survey planning and
preparation of draft sketches in advance of attendance, in order not
to delay the survey execution and the subsequent thickness
measurement report submission within ten (10) working days of the
final attendance onboard. May we remind you that a delay in the
thickness measurement report submission may have an impact and
delay in the provision of required ESP documentation as well as
suitable Condition of Class imposed by the attending surveyors.
9. With regards to tank testing requirements may we refer you to
LR 's Rules and Regulations for the Classification of Ships, Part 1,
Chapter 3, Section 7, Paragraph 7.5.
10. The safety procedures as per the section 'Preparation for
Survey', of the Enhanced Survey Programme (ESP) "Preparation for
Special Survey" booklet, should be implemented accordingly.
11. A copy of this letter and the endorsed Survey Programme
should be placed on board for use by the attending surveyor.
Yours faithfully

Planning of survey
Planning of survey is done by two methods
1-mandatory min survey programme
This programme is worked out for a ship, taking into account the
mandatory min requirements for overall exam, close up survey and
thickness measurements, that have been prescribed by classification
society. Preparation to be carried out for the survey, such as access,
cleaning/descaling, lighting, gas freeing and survey equipment are also
described.
2-survey based on survey planning document( ေဖၚၿပခဲ႔တဲ႔ ESP Document က
ဒီအမ်ိဳးအစါးပါ။)
The survey planning document identifies critical structural areas on an
individual ship, which are high risk. These areas are based on the vessel’s
structural features, its operational features and its damage/repair history.
It stipulates the location, extent and means of close up exam of the area
The planning document is to contain
Main particular of the ship
Plan of tanks/holds with information on their use, cathodic protection and
condition of coating
Corrosion risk nomination of tanks
Design risk nomination of structure
Tanks and area nomination of close up exam
Structure and section nominate for thickness measurement
List of acceptable corrosion allowance for different structure
Risk nomination is an assessment and evaluation of the risk of
deterioration of structures. It takes into account
Design feature such as use of high tensile steel
Local details such as local stresses and local stress concentration
History of ship with regard to corrosion, buckling, cracking, repairs carried
out to and spare parts use on that particular ship as well as sister ships
Information on use of tanks and condition of paint and cathodic protection
on different ship from the office
ESP documentation must not be removed from ship and must remain on board for the entire life of the ship

Close-up surveys
One of the fundamental differences between ESP hull survey requirements
and the previous hull survey regime, is the requirement for close-up
surveys of the structure. This concept now also been adopted for dry
general cargo ship.
According to Lloyd’s register definition of a close up survey, this should be
carried out from distance not more than an arm’s reach away from the
surveyor.

2 Renewal survey
2.1 General 2.1.1. The renewal survey may be commenced at the fourth annual survey and be progressed during the succeeding year with a view to completion by the fifth anniversary date.
2.1.2. As part of the preparation for the renewal survey the survey programme should be dealt with in advance of the renewal survey. The thickness measurement should not be carried out before the fourth annual survey.
2.1.3. The survey should include, in addition to the requirements of the annual survey, examination, tests and checks of sufficient extent to ensure that the hull and related piping as required in 2.1.5 is in a satisfactory condition and is fit for its intended purpose for the new period of validity of the Cargo Ship Safety Construction Certificate, subject to proper maintenance and operation and to renewal surveys being carried out.
2.1.4. All cargo tanks, ballast tanks, pump-rooms, pipe tunnels, cofferdams and void spaces bounding cargo tanks, decks and outer hull should be examined, and this examination should be supplemented by thickness measurement and testing as deemed necessary, to ensure that the structural integrity remains effective. The examination should be sufficient to discover substantial corrosion, significant deformation, fractures, damages or other structural deterioration.
2.1.5. Cargo piping on deck, including crude oil washing (COW) piping, and cargo and ballast piping within the above tanks and spaces should be examined and operationally tested to working pressure to attending surveyor’s satisfaction to ensure that tightness and condition remain satisfactory. Special attention should be given to any ballast piping in cargo tanks and cargo piping in ballast tanks and void spaces, and surveyors should be advised on all occasions when this piping, including valves and fittings, are open during repair periods and can be examined internally.
2.2 Dry-dock survey
2.2.1. A survey in dry-dock should be a part of the renewal survey. There should be a minimum of two inspections of the outside of the ship’s bottom during the five-year period of the Safety Construction Certificate. In all
cases, the maximum interval between bottom inspections should not exceed 36 months.
2.2.2. For ships of 15 years of age and over, inspection of the outside of the ship’s bottom should be carried out with the ship in dry dock. For ships of less than 15 years of age, alternate inspections of the ship’s bottom not conducted in conjunction with the renewal survey may be carried out with the ship afloat. Inspection of the ship afloat should only be carried out when the conditions are satisfactory and the proper equipment and suitably qualified staff is available.
2.2.3. If a survey in dry-dock is not completed in conjunction with the renewal survey or if the 36 month maximum interval referred to in 2.2.1 is not complied with, the Cargo Ship Safety Construction Certificate should cease to be valid until a survey in dry-dock is completed.
2.3 Tank corrosion prevention system
. Where provided, the condition of the corrosion prevention system of cargo tanks should be examined. A ballast tank where a protective coating is found in POOR condition and it is not renewed, or where soft coating has been applied, or where a protective coating has not been applied from the time of construction, the tank in question should be examined at annual intervals. Thickness measurement should be carried out as deemed necessary by the surveyor.
2.4 Extent of Overall And Close-up Surveys
2.4.1. An overall survey of all integral tanks and spaces should be carried out at the renewal survey.
2.4.2. The requirements for close-up surveys at the renewal survey are given in annex 1.
2.4.3. The surveyor may extend the scope of the close-up survey as deemed necessary taking into account the maintenance of the tanks under survey, the condition of the corrosion prevention system and also in the following cases:
.1. in particular, tanks having structural arrangements or details which have suffered defects in similar tanks or on similar ships according to available information;
.2. in tanks which have structures with reduced scantlings in association with a corrosion prevention system approved by the Administration.
2.4.4. For areas in tanks where coatings are found to be in GOOD condition as defined in 1.2.10, the extent of close-up surveys according to annex 1 may be specially considered by the Administration.
2.5 Extent of thickness measurements
2.5.1. The requirements for thickness measurements at the renewal survey are given in annex 2.
2.5.2. Where substantial corrosion as defined in 1.2.8 is found, the extent of thickness measurements should be increased in accordance with the requirements of annex 4.
2.5.3. The surveyor may extend the thickness measurements as deemed necessary.
2.5.4. For areas in tanks where coatings are found to be in GOOD condition as defined in 1.2.10, the extent of thickness measurements according to annex 2 may be specially considered by the Administration.
2.5.5. Transverse sections should be chosen where the largest reductions are suspected to occur or are revealed from deck plating measurements.
2.5.6. In cases where two or three sections should be measured, at least one should include a ballast tank within 0.5L amidships.
2.6 Extent of tank pressure testing
2.6.1. The requirements for tank pressure testing at the renewal survey are given in annex 3.
2.6.2. The surveyor may extend the tank pressure testing as deemed necessary.
2.6.3. Generally, the pressure should correspond to a water level to the top of access hatches for cargo tanks, or top of air pipes for ballast tanks.

2.2 Dry-dock survey
2.2.1. A survey in dry-dock should be a part of the renewal survey. There should be a minimum of two inspections of the outside of the ship’s bottom during the five-year period of the Safety Construction Certificate. In all cases, the maximum interval between bottom inspections should not exceed 36 months.
2.2.2. For ships of 15 years of age and over, inspection of the outside of the ship’s bottom should be carried out with the ship in dry dock. For ships of less than 15 years of age, alternate inspections of the ship’s bottom not conducted in conjunction with the renewal survey may be carried out with the ship afloat. Inspection of the ship afloat should only be carried out when the conditions are satisfactory and the proper equipment and suitably qualified staff is available.
2.2.3. If a survey in dry-dock is not completed in conjunction with the renewal survey or if the 36 month maximum interval referred to in 2.2.1 is not complied with, the Cargo Ship Safety Construction Certificate should cease to be valid until a survey in dry-dock is completed.
No.133 Guidelines for Pilot Schemes of Extended Interval between Surveys in Dry-Dock - Extended Dry-docking (EDD) Scheme 1 Introduction The intervals between inspections of the outside of the ship's bottom are specified in SOLAS,
IACS Regulations and Classification Society Rules and require a minimum of two inspections to be carried out during the 5 year validity period of the Safety Construction Certificate/Special Survey period. SOLAS Regulation I/10(v) only requires a minimum of two inspections of the outside of the ship’s bottom and does not specify a ship must be drydocked out of the water. IMO Resolution A.1053(27) as amended, “Survey guidelines for the harmonized system of survey and certification”, requires that inspections of the outside of the ship’s bottom should normally be carried out with the ship in a dry-dock. However, it also provides that Administrations may give consideration to alternate inspections being carried out with the ship afloat. This document recommends the acceptance procedure for pilot schemes which extend the interval between surveys in dry-dock. Ships eligible for the Extended Dry-Docking (EDD) scheme should meet the provisions and conditions described in this document. Qualifying ships may be permitted to carry out two consecutive in-water surveys, subject to the conditions described in this document. A minimum of two inspections of the outside of the
ships bottom should be carried out during the renewal period of five years and the intervals between any two inspections shall not exceed 36 months. Pilot schemes which extend the interval between out of water dry-docking surveys are normally tripartite projects between the Owner, Flag Administration and the Classification Society. Acceptance into such a Pilot scheme is subject to the formal written agreement with the ship’s Flag Administration including any additional specific Flag Administration requirements. 2 Application Owners/Managers requesting a ship be considered for the EDD scheme, are to apply to the Classification Society in writing confirming and describing compliance with the requirements and conditions specified in this document. Upon the Owner’s request, the extended interval for each ship will be considered on a case by case basis by the Classification Society. The Society may assist in forwarding the Owner’s application to the Flag Administration. The following ships and ship types are not eligible for the extended dry-docking scheme described in these guidelines: • Passenger Ships; • Ships subject to the Enhanced Survey Program (ESP);
• Ships subject to the Hull Survey Requirements of IACS UR Z7.1; • Ships fitted with propulsion thrusters; • Ships where the propeller connection to the shaft is by means of a keyed taper; • High Speed Craft(HSC). The dry-docking scheme will operate based upon the ship’s age when entering the scheme. For ships already in service, the extended dry-docking scheme may be implemented at any time until a ship reaches 10 years of age. No extensions should be granted for the dry-docking required at the end of each extended dry docking period.
