SECTION

1 GENERAL

REQUIREMENTS

A. Survey Intervals and Conditions

A 100 General

101 All ships are to be subjected to periodical surveys to

as-certain the condition of the structure, machinery installations,

equipment and appliances. Periodical surveys will in general

belong to one of the following categories:

— annual surveys

— intermediate surveys

— renewal surveys

— other complete periodical surveys.

The extent of surveys for main and additional class notations are given in Sec.2, Sec.3 and Sec.4. The surveys are, as mini-mum, to be carried out in accordance with the referred rules in

order to confirm that the hull, machinery, equipment and

appli-ances comply with applicable requirements, and will remain in

satisfactory condition provided the assumptions stated in Pt.1

Ch.1 Sec.1 B400 are adhered to.

In cases where compliance with applicable rules can not be

sat-isfactorily confirmed based on extent of surveys as given,

more comprehensive examination and/or testing may, upon the

surveyor's discretion, be required.

102 In cases where the Administration of a flag state

per-forms surveys of the ship and/or its components and equipment

in accordance with the rule requirements, consideration will be

given to the acceptance of this control as basis for retention of

class.

103 Notwithstanding the general implication of 102, for

ships trading with statutory certificates issued by the relevant

national authority and where the Society is not authorised to

carry out surveys, the Society is upon its own discretion, to

car-ry out a general survey with respect to these certificates, in or-der to verify compliance with the rules.

The extent of this survey will be decided upon in each separate case.

104 In cases where the Administration of the flag state has

given dispensation from any requirements in the International

Maritime Standards, the Society may upon its own discretion

accept their decisions as basis for retention of class.

105 The due date of a periodical survey will be established

depending on the survey interval, measured from one of the

following events, whichever is relevant:

— the date of class assignment

— the date of commissioning

— the due date of the previous corresponding survey

— the date of completion of the previous corresponding

sur-vey.

106 Surveys and survey intervals related to class notations

are given in Table A1 and A2 for main class and additional

class respectively.

107 Ships with additional class for which there are no

specif-ic survey requirements in this chapter, are to have the equip-ment and/or constructions related to this additional class

examined to the surveyor's satisfaction at every renewal survey

for main character of class.

A 200 Definitions

201 Convention ship is a ship for which the requirements in

the international conventions apply. The conventions covered

by these rules are applicable with regard to size and type of ship engaged in international voyages as follows:

ICLL For cargo and passenger ships above 24 m.

SOLAS: Safety construction, for cargo ships above 500

gross tonnage.

Safety equipment, for cargo ships above 500

gross tonnage.

Radio communication, for cargo ships above

300 gross tonnage. All passenger ships.

MARPOL: Pollution prevention, tanker for oil, for ships

above 150 gross tonnage.

Pollution prevention for all other ships above

400 gross tonnage.

202 International voyage means a voyage from a country to

which the respective international convention applies to a port

outside such country, or conversely.

203 Passenger ship is a ship which carries more than 12

pas-sengers.

Passenger is every person other than:

— the master and the members of the crew or other persons

employed or engaged in any capacity onboard a ship on

the business of that ship — a child under one year of age.

204 Cargo ship is any ship which is not a passenger ship.

A 300 Annual surveys

301 Annual surveys are normally visual examinations to

as-certain the general condition of the ship or relevant item. A

more thorough annual survey may be specified for particular

structures, machinery installations or equipment due to

conse-quences of failure or age.

302 Annual surveys may unless otherwise stated be carried

out within 3 months on either side of the due date.

303 Annual survey is to be carried out concurrently with

re-newal - or complete periodical surveys.

304 Satisfactory completion of annual surveys for main

character of class and for oil tankers, chemical tankers,

lique-fied gas tankers, dry bulk cargo ships and for ships and plants for refrigerated cargoes, as applicable, will be confirmed by

endorsement on the classification certificate.

305 Surveys completed prior to the specified period, i.e.

more than 3 months before due date, may be accepted. In such

cases the anniversary date on the classification certificate to be

advanced to correspond to a date not more than 3 months later

than the survey completion date.

Subsequent surveys are to be carried out at prescribed intervals

using the new anniversary date.

Expiry date of the classification certificate may remain

un-changed, in which case one or more surveys may be required

with main class 1A1 and at 3-yearly intervals for ships with

main class 1A2.

503 The Society may accept that renewal surveys for hull,

machinery installations and equipment and complete

periodi-cal surveys of cargo containment systems for oil tankers,

chemical tankers, liquefied gas tankers, dry bulk cargo ships

and plants for refrigerated cargoes are commenced concurrent-ly with the fourth annual survey. For surveys commenced prior to the time range for the fourth annual survey, however, sur-veys are to be completed not later than 12 months after the commencement.

504 Possible repairs are normally to be carried out before the

renewal surveys as given in 501 are regarded as completed and

not later than the expiry date of the classification certificate

in-cluding possible postponement granted as given in 700. The

Society may accept that minor deficiencies are rectified within

a specified time limit not exceeding 5 months after expiry date of the classification certificate including possible postpone-ment as given in 700.

A 600 Other complete periodical surveys 601 Examples of complete periodical surveys are:

— surveys at 1, 2.5 or 5 year intervals for additional class

no-tations

— surveys at 2.5 year intervals for boilers

— annual surveys for radio communication

— surveys at 2 year intervals for safety equipment

— surveys at 1, 2.5 and 5 year intervals of safety

construc-tion, pollution prevention, noxious liquid substances and

chemicals and gas codes

— surveys at 1 and 5 year intervals for opening and closing

appliances and load line marks.

A 700 Postponement of periodical surveys

701 Except for annual and intermediate hull surveys, the

So-ciety may accept to postpone periodical surveys upon

consid-eration in each separate case. If postponement is granted, a

condition of class (CC) will be issued giving the time limit for

the postponement period.

No postponement will be given for conditions of class related to overdue continuous machinery and/or hull survey items.

702 Upon the owner's written request an extension of the

va-lidity of the certificate by maximum 3 months may be granted

in exceptional cases. Such request must be received by the

So-ciety prior to the expiry date of the classification certificate.

B. Alternative Survey Arrangements

B 100 Continuous surveys

101 The Society may, upon request from the owners, as an

alternative to the renewal surveys, accept continuous surveys

on the condition that the items are normally surveyed at inter-vals not exceeding 5 years for ships with main character of

class1A1 and 3 years for ships with main character of class

1A2.

However, surveys carried out 6 months or less before their due

date will be given a correspondingly longer interval during the next cycle.

102 Continuous hull survey may be accepted for passenger

ships, container carriers, ro-ro ships and liquefied gas carriers.

The applicable ship types may be recognized if an additional

class notation as listed below, has been assigned:

Passenger Ship Car Ferry Train Ferry

Tanker for Liquefied Gas Container Carrier

Ro/Ro

103 Continuous machinery surveys may be accepted for all

vessels with main character of class 1A1 or 1A2.

B 200 Surveys by the chief engineer

201 The Society may, upon request from the owners, accept

that continuous machinery surveys, subject to the provisions of 202 to 205, may be carried out by the person in charge of the

machinery department (chief engineer). The conditions for

granting this type of survey arrangement will normally be:

— the owner (or managing owner) must confirm the required

qualifications of the chief engineer

— the person has sailed a minimum of 3 years as chief

engi-neer with the relevant national certificate, or alternatively

— the person is presently sailing as a chief engineer with the

relevant national certificate and has been employed with

the owner (or managing owner) for at least 3 years. Chief

engineers previously approved by the Society need not

ful-fil the latter requirement.

Upon acceptance, a chief engineer authorisation letter will be

issued by the Society. On request, the authorisation letter is to

be presented to surveyors of the Society.

202 All surveys taking place at ports where the Society is

represented are to be carried out by surveyors of the Society.

203 Half of all items covered by the continuous machinery

survey scheme, of which there are more than one, may be

sur-veyed by the chief engineer (i.e. the chief engineer may survey

half of all identical items in one five-year survey cycle).

Auxiliary diesel engines and turbines may wholly be surveyed

by the chief engineer. Only a test run including testing of safety

functions in the presence of the surveyor will normally be

re-quired.

204 It is a condition that all surveys carried out under

super-vision of the chief engineer are recorded in the engine log book

and relevant extracts given to the first attending surveyor. The

surveyor may, if he finds it necessary, require a resurvey of the

parts in question.

205 Generator parallel operation, generator load test, and

testing of protection devices for generators and switchboards

are to be witnessed by a surveyor. See also Sec.2 E204.

B 300 Survey arrangement based on an approved planned maintenance system (PMS)

301 A survey arrangement based on a planned maintenance

system (PMS) is an alternative to the continuous machinery

survey (CMS). Such survey arrangement is operated under the

following conditions:

1) The planned maintenance system is to be computer based.

Guidance note:

If the system is centrally operated with the computer ashore, this can be accepted provided that implementation survey and annual survey are carried out both at the location from where the system is operated, and onboard.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---2) The ship is to be manned by chief engineers who are

famil-iar with the system. A chief engineer approved by the

So-ciety shall be onboard at least 50% of the time.

Requirements for approval of chief engineers are given in

201.

3) The planned maintenance system shall be approved (see

302).

4) The manager or operator shall have established a planned

maintenance system that includes at least all items and

systems that are covered by the continuous machinery

sur-vey (CMS) scheme.

5) Maintenance job descriptions and intervals are to be based

on manufacturer’s recommendations. Experience may show that intervals need to be adjusted, in these cases

doc-umentation is required if intervals are to be extended.

6) All components in the CMS scheme are to be clearly

iden-tified with the CMS code in the system.

7) The system shall be able to produce a maintenance history

report of all main overhauls carried out for a specific time

period, see 303.

8) Tthe maintenance may be based on calendar or running

hours, or based on monitoring of condition and

perform-ance.

9) The job descriptions for the main overhaul for all the

com-ponents in the ship’s CMS scheme are to cover the

require-ments for class survey, (see Sec.2, Table E1) and will be

credited as a class survey each time these jobs are carried

out. If some main overhaul intervals are based on running

hours and these intervals normally will exceed 5 years, the

items will still be credited after 5 years based on

satisfac-tory documentation of regular maintenance records and tests.

10) A system for control of components that are being re-used

in different positions (circulating components, e.g. piston,

cylinder cover) is to be established for all such

compo-nents in the CMS scheme.

Guidance note:

It is not required that this system shall necessarily be an integrat-ed part of the planned maintenance system.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---11) The CMS items for sea valves and sanitary valves cannot

be credited by the chief engineer, but shall always be

sur-veyed by a surveyor. The CMS items for parallel

opera-tion, testing of the generators and testing of setting for

main and emergency generators protection devices and

circuit breaker shall always be carried out in presence of a

surveyor. These requirements are to be stated in the

in-structions in the planned maintenance system.

12) All corrective actions are to be especially identified in the

system.

13) The job descriptions and maintenance history are to be in

English.

14) Backup routines are to be established.

15) Annual survey is to be carried out in order to prolong the

validity of the survey arrangement.

16) Damage to machinery or equipment covered by

classifica-tion shall always be reported to the Society and into the

planned maintenance system as a corrective action. The

corresponding repair shall always be verified by a

survey-or.

17) In case of change of manager or operator, the survey

ar-rangement is automatically cancelled.

The survey arrangement may also include the instrumentation and automation equipment covered by the rules in Pt.6 Ch.3 for the class notations E0 or ECO. All jobs related to the

no-tations E0 or ECO have then to be included in the system,

clearly identified, with proper test routines and maintenance

descriptions.

If these conditions are not complied with and the deficiency is not rectified within a given time, the survey arrangement will be cancelled. The conditions for ordinary continuous survey

arrangement (CMS) of machinery will be re-introduced and all

CMS items will be given a due date 5 years from the last sur-vey date.

302 Before a ship may be accepted for alternative survey

un-der a PMS arrangement, the system must be based on an

ap-proved PMS program. This program may be type approved or

approved on a case-by-case basis. Requirements for type

ap-proval are described in a type approval programme in Standard

for Certification 2.9 and in Certification Note 1.2.

Guidance note:

The supplier of the planned maintenance system can obtain type approval while the system approval can be obtained by the man-ager or operator, see 304.

(13)

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---303 The system approval of the planned maintenance system

is based on a description of the system and the following doc-umentation:

1) List of items or systems that are included in the PMS with

the corresponding CMS codes.

2) Examples of maintenance descriptions with corresponding

time intervals and identification of class related

compo-nents (CMS code).

3) Job descriptions for the CMS items for sea valves and

san-itary valves and for parallel operation, testing of the

gen-erators and testing of setting for main and emergency

generators protection devices and circuit breaker. See 301.

4) Example of maintenance history report (class report) for

crediting of CMS components. The report shall at least

contain component name, CMS code, interval, carried out

date (running hours if applicable) and job history.

5) Procedures for reporting of maintenance activity (access

control in the system, which are reporting history into the

system etc.).

6) Description of the functionality for handling of postponed

or overdue jobs.

7) Description of the system for control of components that

are being re-used in different positions (circulating

com-ponents, e.g. piston, cylinder cover).

8) A description of the manager's or operator's maintenance

strategy including a chart of responsibility for the ship and

the management.

9) Description of routines for continuous improvement of the

maintenance strategy and intervals on critical components.

Identification and follow-up of unplanned maintenance,

recording of condition before maintenance is carried out,

and recording of all changes in system are important

ele-ments in this context.

Guidance note:

Maintenance strategy is the manager's or operator's description of how the different machinery items are maintained, that could be time based maintenance, condition monitoring and corrective maintenance.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---When the owner is granted a system approval of their system, a system approval certificate will be issued to the owner stating the system type. A copy of this certificate shall be onboard eve-ry ship that intends to apply for the PMS arrangement.

304 A system approval or a type approval is an approval of

the system itself and it’s functionality, and not an approval of how it is implemented on board each ship. The owner may use the approved system on board all the ship in his fleet, but an

implementation survey is to be carried out on each ship before

the PMS survey arrangement is granted. For type approved

systems, the documentation in items 1, 2, 7 and 8 in 303 are to

be submitted before the implementation survey is carried out.

305 An implementation survey on board the ship is required

in order to verify that all the conditions listed in 301 are

com-plied with. Provided that the implementation survey is carried

out with a satisfactory result, a certificate for the survey

ar-rangement will be issued for the ship stating system type and

conditions for the survey arrangement.

B 400 Integrated survey programme (ISP) - Hull struc-tures and equipment

401 The rules in 400 represent an alternative survey scheme.

This scheme allows the owner's shipboard and shore side

per-sonnel, as given in 403, to partly conduct inspections and tests

as described in 404. The inspections and tests shall be verified by the Society at regular intervals.

402 The requirements given in 403 to 416 replace

require-ments given for traditional periodical and continuous hull

sur-veys carried out by the Society with an integrated survey

program (ISP) which describes specific obligations for the

owner and the Society based on the ship's arrangement,

in-stalled equipment and systems as well as implemented planned

inspection and maintenance system (PIMS).

Guidance note:

For ships with class notation NAUTICUS assigned (see Ch.7) a

degree of exchange between the owner and the Society of infor-mation stored in the product model is defined. 3-D graphical model is part of the product model and consists of a three dimen-sional view of the hull structure and associated features.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---403 ISP is applicable for ships exclusively intended for the

carriage of containers, normally with the class notation

Con-tainer Carrier.

The rules apply to ships with operational patterns which allow a planned and controlled implementation of the program and

application of the ISP will be restricted to ships above a certain

size, normally with a cargo carrying capacity of not less than

1 000 TEU.

It is a prerequisite that the ship has a valid safety management

certificate (SMC) in accordance with the ISM Code.

404 ISP covers inspections of hull structures and equipment

to the extent subject to class surveys as given in Sec.2 C and D and supporting fittings, structures and equipment for stowing and securing of containers as given in Sec.3 B.

Guidance note:

Inspection in this context means visual examination and or pres-sure test.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---405 Intervals for planned inspections and maintenance

should be decided based on the owner's documented

experi-ence and/or designers, builders and manufacturers

recommen-dations. Intervals for examination of hull structures and

equipment covered by ISP, according to 404 are, however,

supposed to be shorter than intervals given for periodical

sur-veys in A400 and A500, applicable for intermediate and

re-newal surveys, respectively.

406 Upon request from the owner, an enrolment letter for

ISP will be issued when documents listed in a) to d) have been

submitted by the owner and reviewed by the Society and the

initial survey as given in 411 has been successfully carried out:

a) Information related to conditions given in 403.

b) PIMS.

c) An organisation chart with defined responsibilities,

au-thorities and interrelations of all personnel who manage,

perform and verify work in accordance with ISP.

d) Qualification and competency of personnel to perform

their assigned functions under the ISP.

Guidance note:

It is assumed that the master's responsibility and authority as de-fined in the ISM Code paragraph 5 are maintained with the ISP. The owner should have a plan on how to provide personnel in-volved in the ISP with adequate understanding of relevant rules and reporting principles, basic knowledge of structural arrange-ment and hull integrity with respect to design, strength and main-tenance.

This may include establishment and maintenance of procedures for identifying any training, which may be required in support of the ISP and to ensure that such training is provided.

In order not to impose a redundant burden, ISM Code documents sufficiently detailed may be suitable also for use in the ISP and

(14)

owner may submit copies of documents of the safety manage-ment components that meet requirements for the ISP.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---407 The following examinations and tests are to be carried

out under the supervision of a surveyor:

a) Thickness measurement of hull structures as given in

Sec.2 C and D. Holds or tanks or spaces required to be

en-tered for thickness measurement are to be internally

exam-ined.

b) Examination of underwater parts in connection with

peri-odical bottom survey. In connection with dry-docking,

holds, tanks and spaces are to be internally examined to an

extent decided by the Society in order to verify structural

condition and level of maintenance as reported as part of

the PIMS and shall comprise representative holds, tanks and spaces as applicable.

c) Annual examination of ballast tanks required as a

conse-quence of non-effective corrosion protection system.

d) Annual examination and thickness measurement of

sus-pect areas as defined in Sec.2 A.

408 The PIMS shall, as a minimum, include a description of

the following:

— identification of all items included

— inspection and maintenance intervals

— inspection and maintenance methods and procedures to be

followed

— inspection and maintenance reporting procedures

— procedure for corrective actions following reported

defi-ciencies.

Guidance note:

The inspection of hull structures should include plating, frames, beams, stiffeners and girders including end connections and welds of all internal members and boundaries for holds, tanks and spaces including hatch covers and coamings as applicable. Evaluation of the condition of corrosion protection system in bal-last tanks and other holds and spaces as applicable should be in-cluded. Piping systems located outside machinery spaces including valves and fittings should be included. Importance of provisions for inspection with particular attention to cleanliness and access to structures in order to discover significant corrosion, deformation, fractures or other structural deterioration should be incorporated.

Guidelines for assessment of acceptance level of deterioration on hull structures and equipment as applicable and evaluation of protective coating condition will be given as part of the ISP. Reporting forms should, as a principle, give information on: — extent of inspection and maintenance with identification of

spaces and specification of structural elements, equipment, pipes, fittings etc. as applicable within each space being in-spected

— results of inspection with condition of coating and anodes (if applicable), structural condition with identification of find-ings as corrosion and defects like cracks, buckling and indents and actions to possible findings including mainte-nance work.

Sketches and photos should generally supplement reports.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---409 The PIMS is to include records applicable to

inspec-tions, maintenance, damages, defects and carried out

correc-tive actions. These are to be kept as objective evidence of the

condition of hull structures and equipment and the effective

functioning of the PIMS. The records are to be readily

accessi-ble to the attending surveyor.

Guidance note:

In order to provide flexibility in the method of documentation, any appropriate record keeping system may be incorporated in

the PIMS including computer-based system. In order to assist the surveyor to conduct the requisite annual surveys as given in 412 without difficulty, suitable cross-referencing may be required.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---410 The implementation of ISP requires that descriptive data

related to the structural condition and level of maintenance for

items included are established.

Guidance note:

Relevant data may be obtained based on results from periodical surveys and/or condition survey and further supported with in-formation available from classification records.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---411 After satisfactory review of documentation listed in 406

and after the PIMS has been in operation onboard for a specific time of normally not less than 6 months, an initial survey is to be carried out to confirm that the ISP is operating as intended.

Guidance note:

During the initial operational period, the Society will evaluate the ability of ship operating personnel to perform their assigned functions.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---412 Surveys for verification of the functioning of ISP are

re-quired annually as given in Sec.2 B206 and Sec.3 B202.

413 If service experience shows wear and tear or defects that

cannot be considered as normal, this shall be reported to the

Society. In such cases the owner shall initiate, in co-operation

with the Society, a special investigation to identify the

cause(s). The Society may require the inspection and

mainte-nance interval shortened until suitable corrective actions have

been implemented.

414 If the hull structure and or equipment covered by the ISP

sustain damage to such an extent that it may be presumed to

lead to a condition of class (see Pt.1 Ch.1 Sec.3 B), the Society is to be informed without delay. The ship is to be surveyed in the first port of call or according to further instructions from the Society.

415 Should it be evident that the conditions for the ISP

en-rolment or the effective functioning of ISP as basis for

reten-tion of class are not complied with, the ISP enrolment will be

cancelled and conditions for ordinary periodical or continuous

survey schemes will be introduced.

416 If the owner and or operator of the ship is changed, the

ISP enrolment will be automatically cancelled.

B 500 Survey arrangement based on condition monitor-ing system

501 For machinery equipped with instruments making it

pos-sible to ascertain the condition of the machinery components,

special approval may be made as to the extent and method of

the survey.

502 For oil lubricated tailshafts that are monitored to

ascer-tain the condition of the tailshaft system during operation, and that fulfils the design requirements in Pt.4 Ch.4 Sec.1 E300, the Society will not require any specific time interval between

complete tailshaft surveys. See also Classification Note 10.1.

A tailshaft condition monitoring survey arrangement (TMON) will be granted in such cases. The arrangement is applicable to

conventional, podded and thruster propulsion systems. Other

arrangements will be subject to special consideration.

Guidance note:

For ships granted TMON prior to 1 July 2001, a survey interval of 15 years between complete tailshaft survey still applies. Ships granted TMON prior to 1 July 2001 may also be granted an un-limited survey interval with respect to tailshaft survey if the

(15)

de-sign requirements in Pt.4 Ch.4 Sec.1 E300 are fulfilled and an application is submitted.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---Dismantling of keyed propellers will be required at intervals of

maximum 5 years, and keyless propellers every 15 years. The

following parts are to be surveyed as applicable:

— propeller nut

— tailshaft threaded end

— key and cone including examination of the keyway and the

fore part of the taper by an approved crack detection meth-od.

503 Ships with more than 3 years since the last tailshaft

with-drawal must carry out a complete tailshaft survey as described

in Sec.2 K100 in connection with the initial TMON

implemen-tation survey, unless the requirements in 504 are met.

504 The following applies to ships applying for the initial

TMON survey arrangement and when it is more than 3 years

since the last tailshaft withdrawal. If a complete satisfactory

record can be presented to the Society containing all relevant

measurements concerning TMON for a period covering the

last 3 years, the requirement for a complete tailshaft survey at TMON implementation survey can be waived. Such records

shall at least include on a monthly basis, stern tube bearing

temperatures with corresponding sea water temperatures, oil

consumption, water content in oil, and in case of roller bearing,

recordings of vibration or shock-pulse measurements or trend

analysis. Where fluid film bearings are applied, bearing

clear-ances from last dry docking and wear down measurements

tak-en since last shaft withdrawal are to be presented. The

documentation is to be submitted to the Society.

505 On board oil analysis for checking of water content and

bearing material particles in the stern tube oil is to be

per-formed monthly and recorded in the TMON record file by the

chief engineer. In addition, at least one oil sample per year is

to be submitted to a recognised laboratory for analysis. The

documentation of the laboratory analysis is to be kept on

board, and shall contain a conclusion regarding the condition

of the oil and it's suitability for further use. The report from the oil analysis presented to the surveyor at annual surveys is to be less than three months old.

Guidance note:

See Classification Note 10.1 Appendix G "Guideline for stern tube lubrication oil analysis."

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---506 Where an oil lubricated fluid film bearing is applied as

an aft stern tube bearing, wear down measurements are to be

taken at each bottom survey and are to be recorded in the

TMON record file.

Guidance note:

When bottom survey is carried out afloat, wear down measure-ments are to be carried out only when practical.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---507 Where roller bearings are used, vibration monitoring is

required to ensure the bearing condition. The vibration signal

is to be measured as velocity or acceleration and recorded in the TMON record file. For more details, see Pt.4 Ch.4 Sec.1 E300.

B 600 Surveys of ships out of commission

601 Ships which have been out of commission, i.e. laid up,

for a period normally of at least 12 months, are to be surveyed and tested before re-entering service. The extent of the surveys and tests will be considered in each case depending upon the time the ship has been out of commission, the maintenance and

preservative measures taken during lay-up and the extent of

surveys carried out during this time. As a minimum, a sea trial

for function testing of the machinery installation will be car-ried out.

602 During lay-up, ships are to be subjected to annual

gener-al surveys.

603 If the lay-up period is more than 12 months, periodical

surveys, except the annual general survey, may be postponed,

depending on the maintenance and preservative measures

tak-en during lay-up.

C. Preparation for Survey
