Rules for Ships, January 2001Pt.1 Ch.1 Sec.1 –

DET NORSKE VERITAS

SECTION 1CLASSIFICATION PRINCIPLES

A. Definitions

A 100 General

101 For definition of general terms used in the rules, see Pt.0Ch.2 Sec.1 A200.

A 200 Rules201 The Rules are to be understood as all those rule require-ments accepted by the Board as basis for classification, whichare developed by the Society or adopted from relevant Interna-tional Maritime Standards as defined in 202. Interpretations ofInternational Maritime Standards and standards for ships out-side the scope of International Maritime Standards, as appro-priate, are included.

202 International Maritime Standards mean internationalIMO conventions, protocols, codes and resolutions, in so far astheir purpose is safety and pollution prevention, excluding ar-ticles and regulations dealing with intergovernmental rela-tions, legal and formal aspects.

203 Tentative rules are rules applying to new fields to whichthe Society reserves the right to make adjustments during a pe-riod in order to obtain the intention reflected in the rules.

204 A Guidance note given in the rules is advice which is notmandatory for assignment of class, but with which the Society,in light of general experience, advises compliance, hence, it isfor the client to decide whether to apply the note or not.

A 300 Audits

301 A vertical contract audit is an IACS audit which assess-es the correct application of the quality system through audit ofthe process for a specific contract.

A contract is the specific agreement between the Society andthe client. It defines the extent of services requested by the cli-ent, and is concerned with:

— the classification of ships, both newbuildings and in oper-ation

— statutory work carried out on behalf of National MaritimeAuthorities

— equipment and materials for ships.

The IACS QSCS (Quality System Certification Scheme) auditteam is responsible for carrying out these audits.

B. The Classification Concept

B 100 General

101 The classification concept comprises the developmentof independent technical standards for ships, and the verifica-tion of compliance with these standards throughout the ships'life.

102 The rules are aimed at ensuring safety against hazards tothe ship, personnel, passengers and cargo, and against hazardsto the environment as a consequence of sea transport.

103 The classification of ships is performed in accordancewith the requirements of the rules and any other standards towhich reference is made.

104 Having assigned class, the society will issue a classifica-tion certificate and enter the main particulars and details ofclass for the ship in the “Register of Vessels classed withDNV”.

B 200 Entering into force and application of rules

201 Rules and amendments accepted by the Board will comeinto force when decided by the Board, normally six (6) monthsafter acceptance.

202 Entry into force and application of those parts of therules covering International Maritime Standards are indicatedat the beginning of each of the relevant rule chapters.

203 The rules, which are in force at the date of the written re-quest for classification, are the basis for the assignment andmaintenance of class.

Subsequent amendments not made mandatory according to204 may be made applicable to ships under construction pro-vided both builder and owner agree to such application.

204 If an amendment is made mandatory to ships under con-struction or which have already been assigned class, this willbe specially stated.

205 In exceptional cases, where unacceptable service expe-rience and/or theoretical findings clearly show that safety haz-ards may arise in connection with items covered by the existingrules, the Society may lay down supplementary requirementsconcerning the assignment and retention of class to maintainthe overall safety standard reflected by the rules.

206 The Society will consider alternatives found to representan overall safety standard equivalent to that of the rules. Ap-proval may be revoked if subsequent information indicates thatthe chosen alternative is not satisfactory.

With regard to equivalent alternatives, those parts of the rulescovering International Maritime Standards shall be practised inaccordance with procedures agreed by the National Authoritiesinvolved.

207 If disputes should arise in connection with the applica-tion of those parts of the rules that are adopted from Interna-tional Maritime Standards, the text of the InternationalMaritime Standards is to prevail.

Text adopted from International Maritime Standards and pre-sented in quoted form, is printed in italics.

208 In cases where detailed requirements are not given in therules, specific solutions or decisions approved by the Societyand its surveyors are to be based on the principles of the rules,and are to give a safety standard equivalent to that of the rules.

209 In accordance with 206 the Society may consider the useof reliability methods as a means of documenting complianceto class requirements. For applications to hull structures, seePt.3 Ch.1 Sec.3 B1000.

B 300 Basis for assignment of class

301 Having assigned a specific class implies that the Socie-ty:

— has been satisfied that the ship meets the rule requirementsfor the particular class

— will, through a system of surveys, verify that the require-ments stipulated for retention of class are complied with.

302 Prior to assigning class to an eligible, existing ship, it isin general to undergo all periodical surveys pertaining to theage and type of the ship. See Sec.3 A705.

303 When assigning class to a ship which has not been builtunder supervision of the Society, provided the ship has beenbuilt under supervision of another recognised classification so-ciety, the Society may on the basis of an overall safety consid-


DET NORSKE VERITAS

eration, in connection with a design review and survey, exemptit from rule requirements for the main class. See also 206.

304 When assigning class to a ship of a series under con-struction to the classification of, or a design previously accept-ed by, a recognised classification society, the Society may onthe basis of an overall safety consideration, in connection withthe design review, exempt it from the rule requirements for themain class, and base the survey on design review done by therecognised society. See also 206.

305 When assigning class to a ship for which the Adminis-tration of the flag state undertakes approval and surveys ofitems covered by the rules, the Society may accept their deci-sions as basis of assigning class.

306 For ships permanently moored on location and intendedfor production and storage of hydrocarbons, the Society mayalso accept decisions by the National Authority with jurisdic-tion over the waters in which the ship is to operate (shelf state)as basis for assigning class.

B 400 Basis for maintenance of class

401 The requirements for retention of class are found inSec.3 B. In addition, classification is based on the followingassumptions:

Maintenance of the ship and its equipment

The ship, machinery installations and equipment are to bemaintained at a standard complying with the requirements ofthe rules.

Installed systems or equipment carried on board in excess ofthe rule requirements, but otherwise covered by the rules, areeither to be maintained in accordance with the rules, or be re-moved or be disconnected in such a way as to ensure that theinstalled system or equipment cannot be used.

Handling of the ship

The ship, machinery installations and equipment are to be ad-equately manned and competently handled. This includes alsostowage of cargo, distribution of ballast and bunkers, andspeed and navigation in heavy weather. Class conditions re-garding the use of the ship are to be observed.

Valid statutory certificates

The statutory certificates of the applicable international con-ventions are to be valid at all times, and the surveys prescribedin the conventions are to be carried out within the time win-dows prescribed.

B 500 Documentation

501 All information which may influence the judgement, de-cisions and requirements of the Society for the purpose of clas-sification, is to be made available to the Society. It is theclient's responsibility to ensure that such information isbrought to the attention of the Society in a timely manner. In-formation may be made available by submitting documents tothe Society or by surveys performed at the clients premises, theship or the premises of the client's sub-contractors.

502 Documents for information or approval required in eachchapter of the rules are to be submitted to the Society.

503 The documentation forming the basis for classificationis, at all times, to reflect the true conditions. Revisions of doc-uments are therefore to be submitted to the Society to the ex-tent such revisions may influence decisions and requirementsof the Society.

B 600 Disclosure of information

601 The Society will not disclose any information receivedor reports made in connection with classification to any otherthan those entitled thereto or those having been given the right

to receive information by legislation, court decision or by writ-ten permission by the owner. The supply of information maytake place electronically and on a continual basis, e.g. by on-line access to the Society's databases.

Guidance note:Table B1 indicates which parties will be entitled to various kindsof information.

---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---

602 The Society will not disclose information that can beconsidered as the property of another party except when thisparty's permission is given in writing.

603 Internal communication, notes, calculations etc. pro-duced within the Society in connection with classification willnot be disclosed to other parties.

604 Notwithstanding 601 to 603, authorised representativesof the maritime Administration or of the audit team of IACSperforming quality audits, will have access to such informa-tion. These representatives are to confirm in writing that theyare not in any manner allowed to reproduce or communicatesuch information to other parties.

B 700 Limitation of the Society's responsibility

701 The classification service is performed on the basic as-sumption that other parties involved (building yard, designers,manufacturers, sub-contractors, shipowners, etc.) fulfil theirindividual obligations. The classification service is not per-formed in substitution of other parties' role or obligations.Nothing contained herein or in any certificate, report or docu-ment issued in connection with or pursuant to these rules, shallrelieve any designer, engineer, builder, manufacturer, ship-yard, seller, supplier, owner, operator or other parties from anyobligations or consequences of default whatsoever. In particu-lar, compliance with the rules does not imply acceptance orcommissioning of a ship. This is the exclusive responsibility ofthe owner.

Any document issued by the Society in relation to surveys per-formed reflects the condition of the ship at the time of survey.It is the responsibility of the owner to maintain the conditionof the ship as required by the rules between surveys.

B 800 Vertical contract audits and audits by National Maritime Authorities801 For the purpose of conducting vertical audits performedby the audit team of IACS, and audits performed by the Na-tional Maritime Authorities of the flag state, access is to beprovided to the ship and/or to the premises of manufacturer orshipbuilder, as appropriate.

B. Class Notations

B 100 General

101 All ships will be given a main class consisting of a con-struction symbol, a main character of class, and where applica-ble, a service area restriction notation, e.g.:

✠ 1A1

or

✠ 1A1 R2

102 Ships also found to satisfy relevant requirements may begiven additional class notations related to special service andtype of ship, special systems and equipment or to special fea-tures.

The complete class notation will thus consist of (as exempli-fied):

✠ 1A1 R2 Tanker for Oil ESP E0 ETC

Main class notations:

✠ — Construction symbol1A1 — Main character of classR2 — Service area notation

Additional class notations:

B 200 Construction symbols

201 The symbol ✠ will be given to ships built under the su-pervision of DNV.

202 The symbol will be given to ships built under the su-pervision of a recognised classification society and later as-signed class with DNV.

B 300 Main character of class

301 The notation 1A1 will normally be given to ships withmachinery and equipment found to be in compliance with therule requirements stated in Pt.1, 2, 3 and 4.

302 The notation 1A2 will normally be given to ships foundto meet the rule requirements, where by reason of special de-sign, materials, general condition and/or age, it is considerednecessary to stipulate shorter intervals between surveys thanthose which are normally required for ships with the notation1A1.

B 400 Service area notations

401 The notation R followed by a number or a letter will begiven to ships with certain modifications to arrangement,equipment or scantlings in relation to ships normally built forwinter weather conditions in the North Atlantic.

The service area restrictions given in nautical miles and repre-senting the maximum distance from nearest harbour or safe an-chorage are given in Table B1. For the various servicenotations the restrictions are related to the zones, areas and sea-sonal periods as defined in Pt.3 Ch.5 Sec.5 (the InternationalConvention on Load Lines, 1966, Annex II).

The service notation RE is limited to enclosed waters such asfjords, harbours, rivers and smaller lakes.

The service area restrictions as related to the given service areanotation are to be included in the “Appendix to the classifica-tion certificate”.

402 Modified requirements related to the various servicearea notations are given in the relevant sections of the rules.The modifications will affect:

SECTION 3CLASSIFICATION PROCEDURE

A. Assignment of Class

A 100 Request for classification

101 A request for classification of a ship is to be submittedin writing by the client.

A 200 Requirements for workshops and yards

201 Builders unknown to the Society are to demonstratetheir capability to carry out fabrication of adequate quality inaccordance with the rules before construction is started.

202 Welding of important structures, machinery installationsand equipment is to be carried out by approved welders, withapproved welding consumables and at welding shops acceptedby the Society. Requirements for approval of welding shops,welders, manufacturers of welding consumables, welding con-sumables and welding procedures are given in the rules (seePt.2 Ch.3).

203 During fabrication and construction work, the Society'ssurveyors are to have safe access to the works at all reasonabletimes, insofar as the work affects classification. The client is toensure, through contracts with the parties concerned or other-wise, that such access is possible, and that the Society is noti-fied as to when and where the surveyor's attendance is needed.

204 The following general documentation from the builder(workshop and yard) and from subcontractors (as specified in301) is to be submitted when requested by the Society:

— outline specification for the ship— list of subcontractors to the building yard— list of subcontractors to the manufacturer of products to be

delivered, if applicable.

A 300 Requirements for manufacturers

301 Manufacturers of materials, components and equipmentof categories not covered by 200 are to be considered for ap-proval according to criteria established by the Society, as ap-plicable.

302 Any required quality control of materials, componentsand equipment, is to be traceable and documented in writing.Further, quality control is to be carried out by qualified person-nel at facilities and with equipment suitable for that control.

A 400 Requirements for suppliers of services

401 Suppliers providing services on behalf of the owner,such as measurements, tests and maintenance of safety systemsand equipment, the result of which may form the basis for thesurveyor's decisions, are to be approved by the Society, ac-cording to criteria established by the Society.

Where surveyors use such services in making decisions affect-ing statutory certifications, the suppliers are subject to approv-al by the Society, where the Society is so authorised by therelevant flag Administration. For such services the Societymay accept approvals done by the flag Administration, or dulyauthorised organisations acting on behalf of the flag Adminis-tration.

A 500 Requirements for calibration of equipment

501 Measuring and test equipment used in services by man-ufacturers, builders, repairers or owners, the result of whichmay form the basis for the surveyor's decisions, is to have acalibration status or an appropriate accuracy to the surveyor'ssatisfaction.

A 600 Plan approval

601 The builder or manufacturer shall submit the followingdocumentation, as specified in the applicable chapters of therules, and according to documentation lists supplied by the So-ciety upon receipt of class request, before production com-mences:

a) Plans and specifications required for approval, in tripli-cate, including one copy for each sister ship, as applicable.Moreover, the Society may specify alternative or addition-al requirements.

b) Corresponding technical descriptions, calculations and da-ta, including material specifications.

Any documents submitted for re-approval are to be especiallymarked to identify the revised parts.

The builder, with which the Society has the classification con-tract, is responsible for co-ordinating that plans and other doc-uments are submitted, and for distributing any approvalcomments that may have been given.

602 When a ship, which is not built under supervision of theSociety, is to be classified, the information required in 601 is,in general, to be submitted for approval. The extent of docu-mentation approval for a ship, which is classed, or which waspreviously classed, with another recognised classification so-ciety, will be decided upon in each case.

603 Plans that have been found to comply with the rule re-quirements will be provided with a statement of approval.Conditions and limitations of the approval may be stated on theplans returned with the statement of approval, or in the accom-panying letter of approval.

604 The approval may be revoked at any time if subsequentinformation indicates that the design solution was contrary tothe rule requirements or intentions.

605 The English language shall be used in plans and specifi-cations submitted for approval.

The possibility of using the local language shall be agreedupon in each case.

606 When plans and documents are submitted as electronicfiles, the format and transfer method shall be agreed upon ineach case.

A 700 Survey

701 When a ship is built under the supervision of the Society,the Society will verify:

— that the construction and scantlings comply with the rulerequirements and the approved plans, and that the requiredmaterials are used

— that the materials, components and systems have been cer-tified in accordance with the rules

— that the work is carried out in compliance with the appli-cable rules and with good engineering practices. IACS"Shipbuilding and Repair Quality Standard - Part A" is re-garded as an example of a standard regarding hull struc-tures describing such good engineering practices.

— that satisfactory tests are carried out to the extent and in themanner prescribed by the rules.

Supervision is to be carried out at the building yard and/or thesub-suppliers at the discretion of the Society, which also de-cides the extent and method of control.


DET NORSKE VERITAS

702 The verification method applied by the Society at thebuilding yard or at the manufacturers' will normally be basedon visual inspections and tests.

The Society may base its verification on audits of an acceptedQuality System implemented at the yard or at the manufacturerin combination with an agreed manufacturing survey arrange-ment.

703 When a ship, which has not been built under the super-vision of the Society, is to be classified, the Society will carryout surveys to confirm:

— that the design and scantlings comply with the approvedplans

— that the material, components and systems are in accord-ance with the rules

— that the workmanship is in compliance with the applicablerules and with good engineering practice.

Functional tests are to be carried out as deemed necessary bythe Society.

704 For ships built under the supervision of another recog-nised society the requirements of 703 will normally be consid-ered as complied with for the main class.

705 When an existing ship is to be classified it is in generalto undergo all periodical surveys pertaining to the age and typeof the vessel. Ships previously classed by a recognised societywill, as a minimum, be subject to an annual survey, in accord-ance with Pt.7 Ch.2, with special emphasis on the ship's gener-al condition and including thickness measurements for ships ofage exceeding 10 years. In addition, any periodical surveys duewith the previous society are to be carried out.

If the age of the ship exceeds 20 years, it is to undergo a sight-ing survey with an extent as for renewal survey irrespective ofwhen this is due with the previous society.

A 800 Functional testing

801 A test programme is to be prepared by the builder to thesatisfaction of the surveyor. The programme is to specify sys-tems and components to be tested, and the testing procedure.The programme is to include sea trials of the ship with machin-ery and equipment installed.

802 The tests are to give evidence as to satisfactory operationin accordance with the rules. When testing the control andsafety system, failure modes are to be simulated as realisticallyas possible.

803 Unless otherwise agreed, the testing required by therules is to be carried out in the presence of a surveyor.

Data are to be recorded according to the test programs and asconsidered necessary by the surveyor.

A 900 Certification of materials, components and sys-tems

901 The scope of classification includes certification of ma-terials, components and systems intended for the ship. The ap-plicable chapters of the rules define the extent of thecertification that is needed for classification. The objective ofthe certification is to ensure that materials, components andsystems used in ships to be classed by the Society conform tothe rules and other standards within the framework of the rules.

The certification is a conformity assessment normally includ-ing both design and production assessment.

The production assessment includes inspection and testingduring production and/or of the final product.

902 The design assessment of the materials, components andsystems shall either be on a “case by case” basis or follow theprocedure for type approval.

903 When the “case by case” procedure is used, documenta-tion of the design shall be submitted for assessment for everyapplication as required in the applicable chapters of the rules.

A design assessment letter or design verification report shall beissued by the Society when compliance with the requirementsfor the design for the actual application is confirmed.

904 When the type approval procedure is used, documenta-tion of the design and the results of type testing as required intype approval programmes and the applicable chapters of therules, shall be submitted for assessment. A type approval cer-tificate shall be issued by the Society when compliance withthe requirements for the design is confirmed. The type approv-al certificate has a validity of 2 or 4 years depending on type ofmaterial, component and system.

905 The production assessment of materials, componentsand systems shall either be on a “case by case” basis or on thebasis of an agreed Manufacturing Survey Arrangement(MSA).

906 When the “case by case” procedure is used, the surveyand testing shall be performed on the basis of approved designdocumentation for the actual application and as required in theapplicable chapters of the rules. Compliance with the approveddesign documentation and the requirements shall be docu-mented through certificates as required in the applicable chap-ters of the rules.

907 When the production assessment is based on an MSA,the survey and testing shall be performed on the basis of ap-proved design documentation and in accordance with require-ments and procedures laid down in the MSA. Compliance withthe approved design documentation and the requirements shallbe documented through certificates as specified in the MSA oras required in the applicable chapters of the rules.

908 Certification of materials, components and systemsshall be documented by the following types of documents:

1) Det Norske Veritas Product Certificate (NV):

A document signed by a surveyor of the Society stating:

— conformity with rule requirements— that tests are carried out on the certified product itself— that tests are made on samples taken from the certified

product itself— that tests are performed in presence of the surveyor or

in accordance with special agreements.

2) Works Certificate (W):

A document signed by the manufacturer stating:

— conformity with rule requirements— that tests are carried out on the certified product itself— that tests are made on samples taken from the certified

product itself— that tests are witnessed and signed by a qualified de-

partment of the manufacturers.

3) Test Report (TR):

A document signed by the manufacturer stating:

— conformity with rule requirements— that tests are carried out on samples from the current

production.

The applicable chapters and sections of the rules will specifywhich of the above mentioned documentation will be required.

909 Where the rules require Works Certificate (W) or TestReport (TR), the surveyor may at any time require tests to becarried out in his presence and/or check elements of the qualitycontrol in operation.


DET NORSKE VERITAS

910 For identification and traceability, certified products areto be stamped in accordance with the marking given in theproduct certificate and as specified by the applicable chaptersof the rules.

911 For certain components and systems as defined in theapplicable chapters of the rules, the certification may be basedon defined internationally recognised standards and certifica-tion schemes that cover the overall quality, safety and environ-mental standard of the rules. Compliance with therequirements of the standard shall be documented as requiredby the standard.

912 To ensure an efficient, cost effective and correct certifi-cation process, a General Certification Agreement is normallyto be established with manufacturers delivering NV certifiedproducts.

The General Certification Agreement may be part of a Manu-facturing Survey Arrangement.

The General Certification Agreement is to include informationon the procedures for design and production assessment and ontransfer of information and experience between the Manufac-turer and the Society.

A 1000 Manufacturing Survey Arrangement

1001 When the procedures and processes of a building yard'sor a manufacturer's quality system meet the quality, safety andenvironmental standard of the rules, a Manufacturing SurveyArrangement (MSA) may be established with the yard or themanufacturer as an alternative to the verification and produc-tion assessment described in the applicable rule chapters.

1002 The agreed MSA is to be described in a document stat-ing the requirements, scope, acceptance criteria, documenta-tion and the roles of the Society and the yard or themanufacturer in connection with the production assessment.

1003 When it is agreed through an MSA that the majority ofthe required surveys and tests are being completed without thepresence of a surveyor, it is conditional upon the manufacturerthat he has in operation a quality system certified by an accred-ited certification body to ISO 9002, or equivalent.

1004 When establishing an MSA, an initial assessment of themanufacturer’s ability to control product quality and to complywith the scope, requirements and criteria laid down in the MSAshall be performed.

The extent and frequency of periodical assessments of themanufacturer shall be included in the MSA.

1005 An MSA is normally given a validity of 4 years. Whenthe MSA is based on a certified quality system, the MSA auto-matically becomes invalid if the quality system certification isno longer valid.

A 1100 Type approval

1101 Type approval is a procedure for design assessment.Type approval can be applied to a:

— product— group of products— system.

This procedure should normally be used for design assessmentof standard designs.

1102 The type approval procedure will normally consist ofthe following elements:

— design approval— type testing— issuance of type approval certificate.

The type approval procedure used by the Society is describedin Standard for Certification No. 1.2.

1103 For certain products and systems as defined in applica-ble chapters of the rules, type approval is sufficient for certifi-cation of product quality, i.e. production assessment is notrequired.

1104 For certain products and systems as defined in the ap-plicable chapters of the rules, type approval is a mandatoryprocedure for design assessment.

1105 For products and systems manufactured for stock, typeapproval is to be the normal procedure for assessment of de-sign.

1106 For type approved products, where the basis for ap-proval are the rules of the Society, plans and technical descrip-tions of the product need not be submitted for approval foreach ship unless otherwise stated as a condition on the type ap-proval certificate. In such cases only the arrangement or sys-tem plans, interface plans and those plans mentioned on thetype approval certificate are to be submitted for approval.

A 1200 Acceptance of control by National Authorities1201 In cases where the Administration of a flag state re-views plans, carries out type approval, and surveys the shipand/or its components and equipment in accordance with therule requirements the Society will normally accept the approv-al and survey by the flag administration as basis for assignmentof class. Necessary documentation including copies of ap-proved plans, reports and other particulars approved by the Na-tional Authorities have to be submitted.

A 1300 Certificate of interim class1301 When the surveyor is of the opinion that the require-ments corresponding to the class in question have been met, hewill document the completion of the building supervision byissuing the certificate of interim class, which is valid until theadministration of the Society has confirmed the class and is-sued the classification certificate.

1302 At the discretion of the surveyor the building supervi-sion may be considered to be completed with some minoritems unverified, provided Conditions of Class (see B800) areissued to the effect that the remaining work, surveys or othermeasures are to be completed within a specified time. At thesame time the surveyor will document the completion of thenewbuilding supervision by issuing the certificate of interimclass as indicated in 1301.

1303 In case of classification of an existing ship not built un-der the supervision of the Society, or classification of an exist-ing ship previously classed by the Society, the surveyor willissue the certificate of interim class when he is satisfied that theapplicable requirements have been met.

A 1400 Classification certificate1401 When the administration of the Society has examinedthe surveyor's report and is satisfied that the requirements cor-responding to the class in question have been met, the classwill be assigned and a classification certificate will be issued.

Provided the requirements for maintenance of class will becomplied with, and unless the class has been withdrawn inwriting at an earlier stage, the classification certificate will bevalid for 5 years or 3 years for ships with main character ofclass 1A1 or 1A2, respectively.

1402 Declarations confirming compliance with the rulesmay upon request be issued for propulsion machinery, mainboilers and specific additional class notations, provided the So-ciety's main class has been assigned.

A 1500 Appendix to the classification certificate1501 An “Appendix to the classification certificate” will beissued stating assumptions for the assignment of class and con-ditions regarding the use of the vessel which were establishedor assumed at the time of assignment of class.


DET NORSKE VERITAS

A 1600 Entry in the «Register of Vessels classed with DNV»1601 When a ship has been assigned class, its main particu-lars and details of class will be entered in the Register. In addi-tion to the class notations, an appropriate type descriptive notemay be entered in the Register, indicating the type of the shipin greater detail than given in the class notations, and/or pro-viding additional information on the ship's functions, designand construction. This descriptive note is provided for infor-mation only and is not to be regarded as part of the ship's classnotations.

1602 For ships built under the supervision of the Society, theclass is entered with a statement of the year and month fromwhich the periodical surveys will be dated. For other ships anotation is made of the year and month of completion of thesurvey mentioned in 705.

1603 If the ship is not immediately commissioned uponcompletion of the building supervision, the ship is subject to acondition survey at the time when she enters service. Providedthe result of this survey is in all respects satisfactory, subse-quent periodical surveys will date from the time of the condi-tion survey.

B. Retention of Class

B 100 General101 In order to retain a ship's class with the Society, the own-er is to:

— submit complete and correct information on the ship andits use, which would be of significance to the Society forits assessment of the condition of the ship in relation to therules

— submit complete and correct information on the ownershipand management of the ship, addresses and correspondingadministrative information pertinent to the relations withthe Society

— subject the ship to prescribed periodical and renewal sur-veys, surveys of damage, repairs, conversions and altera-tions

— subject the ship to unscheduled surveys when deemed nec-essary by the Society

— rectify deficiencies and carry out Conditions of Class (see800) specified by the Society in accordance with the ruleswithin the given time limit

— pay all fees and expenses due to the Society.

102 It is the duty of the owner to request surveys from theSociety and to provide the assistance and safe access requiredto the extent necessary for completion of the surveys in accord-ance with the rules.

103 It is a prerequisite for retention of class that:

— the statutory certificates of the applicable internationalconventions, as stated in Sec.2 A102, are valid at all times

— the surveys prescribed in the conventions are carried outwithin the time frames prescribed

— the certificates are issued by the Society when so author-ised or else by the Flag Administration itself, except forthe Cargo Ship Safety Radio Certificate where the Societymay accept the certificate issuance by any organisation au-thorised by the Flag Administration.

Guidance note:In case of dually classed vessels, the Society may accept statuto-ry certification by the 'dual' class society, upon agreement.

104 In co-operation with port states, a surveyor will attendon board a classed vessel when so requested by a port state, in

order to assist in the rectification of reported deficiencies orother discrepancies related to classification.

Prior to attendance on board, the surveyor will inform the own-er or owner's representative (master or agent). Where appropri-ate, the vessel's flag state will be notified of such attendanceand survey.

B 200 Periodical and renewal surveys

201 A ship is to be subjected to surveys with frequency andextent stipulated in Pt.7 Ch.2.

Surveys covered by the rules which are carried out by NationalAuthorities of the flag state may be accepted as basis for the re-tention of the class, subject to the provisions of A1200.

B 300 Survey of damage

301 If the hull, machinery installations or equipment coveredby classification sustain damage of such extent that it may bepresumed to lead to a Condition of Class (see 800), the Societyis to be informed without delay. The ship is to be surveyed inthe first port of call or according to further instructions fromthe Society. The survey is to be of the extent which the survey-or considers necessary for ascertaining the amount of damage.

B 400 Repairs

401 When hull, machinery installations or equipment is cov-ered by classification and is to be subjected to repairs of anysignificance, then the work shall be carried out under the su-pervision of a surveyor, by qualified personnel and in compli-ance with the applicable rules, and with good engineeringpractices.

IACS "Shipbuilding and Repair Quality Standard - Part B" isregarded as an example of a standard concerning hull struc-tures that describe such good engineering practices. Guidelinesfor hull repairs can be found in Classification Note No. 72.1.

402 If repairs stipulated in 401 are to be carried out duringvoyage, without the attendance of a surveyor, a repair plan isto be approved by the Society in advance.

Repairs will only be accepted to an extent and by methodswhich at any time do not seriously affect the main functions ofthe vessel and its watertight and structural integrity.

In cases where repairs are carried out without attendance of asurveyor, documentation with respect to quality of materialsused, and the qualification of personnel having carried out therepairs, are to be available when the surveyor is called for ac-ceptance.

B 500 Procedures for maintenance
