structural strength and integrity of the hull andits elements including structural fire protection;

seaworthiness (stability) of the ship under allspecified loading conditions and under particular sea-and-wind conditions;

safe and reliable operation of its propulsionplant, systems and devices for ship control, othersystems, auxiliary machinery and equipment includ-ing fire-fighting equipment,

and thereby permit safe operation of the ship inaccordance with its purpose.

D a t e o f c o n t r a c t f o r c o n s t r u c t i o no f a s h i p ( s e r i e s o f s i s t e r s h i p s ) unlessspecified otherwise is the date on which the contractto build the ship is signed between the prospectiveowner and the shipbuilder. This date is normally tobe declared to the classification society by the partyapplying for the assignment of class to a newbuilding.

The date of "contract for costruction" of a seriesof sister ships, including specified optional ships forwhich the option is ultimately exercised, is the dateon which the contract to build the series is signedbetween the prospective owner and the shipbuilder.

Sister ships are ships built to the same approvedplans for classification purposes. The optional shipswill be considered part of the same series of sisterships if the option is exercised not later than 1 yearafter the contract to build the series was signed. Sisterships may have minor design alterations providedsuch alterations do not affect matters related toclassification.

Part I. Classification 17

If a contract for construction is later amended toinclude additional ships or additional options, the dateof "contract for construction" for such ships is the dateon which the amendment to the contract is signedbetween the prospective owner and the shipbuilder. Theamendment to the contract shall be considered as a"new contract" to which the above explanations apply.

N o t e s . 1. By optional ships, ships are meant which areincluded in the contract without determining their construction dates.

2. This explanation applies to ships for which the contractfor construction is signed on 1 January 2005 or later.

A d d i t i o n a l r e q u i r e m e n t s are the re-quirements caused by the object features or itsoperational conditions, which are not provided for bythe rules imposed by the Register in writing to ensurethe safety of objects under technical supervision.

T h e R e g i s t e r c l a s s ( c l a s s ) is a combi-nation of conventional characters and descriptivenotations assigned to the ships, other floatingfacilities, as well as to fixed offshore platforms,which define their structural features, purpose andoperational conditions stipulated by the Rules.

A n o p e r a t o r is a physical person or legalentity operating a ship on the basis of a contractconcluded with a proprietor or shipowner.

R u l e s ( t h e R e g i s t e r R u l e s ) are the setof the regulating and technical requirements forobjects under technical supervision.

The Register Rules are listed in 1.3 of the GeneralRegulations for the Classification and Other Activity.

A p r o p r i e t o r is a physical person or legalentity having proprietary rights to a ship irrespectiveof the fact whether he (she) or it operates the ship onhis (her) or its own, or has placed it in the operationof another person or entity whether on the fiduciaryor some other legal basis.

S p e c i a l c o n s i d e r a t i o n is the determina-tion of the extent, to which an object under technicalsupervision meets the additional requirements.

S t a n d a r d s , as applied to the Rules, means allkinds of standards and other regulating and technicaldocuments of all countries approved or recognized bythe Register.

A s h i p u n d e r c o n s t r u c t i o n is a shipduring a period from the date of laying the keel tillthe date of issuing the documents for a ship. The dateof laying the keel means the beginning of construc-tion identifiable with a specific ship when the mass ofthe assembled part of a hull comprises not less than50 tons or 1 per cent of the estimated mass of allstructural material, whichever is less.

A s h i p i n s e r v i c e is a ship which is notunder construction.

A s h i p o w n e r is a physical person or legal entityoperating a ship on his (her) or its own behalf irrespectiveof the fact whether he (she) or it is the proprietor or isoperating the ship on some other legal basis.

18 Rules for the Classification and Construction of Sea-Going Ships

1.2.6 Confirmation of compliance with the require-ments of the Register rules is the Register prerogativeand is carried out in accordance with the procedureestablished by it.

Any statements to the effect a supervised item

complies with the rules requirements, which are madeor documentally supported by a body other than theRegister and which are not confirmed by the latter inaccordance with the established procedure, cannot beconsidered as evidence of such a compliance.

2 CLASS OF A SHIP

2.1 GENERAL

2.1.1 Assignment of the Register class to a shipmeans confirmation by the Register that the shipconstruction complies with the applicable requirementsof the Register rules and its technical conditioncomplies with the conditions of the ship operation;the ship is registered with the Register for a specifiedperiod with performing the surveys stipulated by Rulesfor the Classification Surveys of Ships for this period.

2.1.2 The Register may assign a class to a shipproceeding from the results of survey during itsconstruction, as well as assign or renew a class to aship in service.

2.1.3 Renewal of a ship's class means confirmationby the Register that the construction and technicalcondition of the ship comply with the provisions basedon which a class has been assigned as well as extensionof vality of the Register documents for a definite periodas required by the Rules.

2.1.4 Class of a ship is, generally, assigned orrenewed by the Register for 5 years, however, insound cases the Register may assign or renew a classfor a lesser period.

2.1.5 If a ship has the valid Register class thismeans that the ship's technical condition in full measureor to a degree considered adequate by the Registercomplies with the requirements of the Rules whichapply to it according to its purpose, service conditionsand class notation. If a class of a ship is valid it iscertified by the valid Classification Certificate on board.

2.1.6 Classification Certificate shall cease to bevalid and the class shall be liable to be suspended inthe following cases (including cases where the annualsurvey is not completed and the validity of Classifica-tion Certificate is not confirmed within three monthsfrom the date fixed for the annual survey):

if the ship as a whole or her separate elementshave not been subjected to scheduled periodical oroccasional surveys in specified terms;

after an accident, the ship shall be submitted foroccasional survey at the port where the accident tookplace or at the first port of call, if the accident tookplace at sea;

if alterations not agreed with the Register havetaken place in the construction and/or if any changehas been made in the equipment which may result inreducing the standards required by the Rules;

when repair of a ship's items has been performedwithout the agreement of and/or survey by the Register;

when a ship navigates with a draught exceedingthat specified by the Register for specific conditionsas well as in case of operation of a ship in conditionswhich do not comply with the requirements forassigned class of a ship or the restrictions specified bythe Register;

if the prescribed specific requirements which duringprevious survey of the ship were the conditions forassignment or retainment of the Register class have notbeen fulfilled within the specified period;

if the process of surveying the ship by theRegister has been suspended on shipowner's initiativeor through his fault;

when the ship has been taken out of service for along period (more than 3 months) for fulfilment ofthe Register requirements (except the case when aship is under repair for these purposes).

The Register shall specially notify the shipownerof suspension of a ship's class and ClassificationCertificate.

2.1.7 Suspended (as stated in 2.1.6) class of a shipmay be reinstated on the basis of satisfactory results ofthe appropriate periodical or occasional survey carriedout by the Register in the case of ship to be submittedfor survey. In so doing when the ship is taken out ofservice for a long period (more than 3 months), thescope of survey for reinstatement of a ship's class shallbe specially established by the Register taking intoaccount the age and condition of the ship as well as theperiod for which she is taken out of service.

During the period from suspension of a class toits reinstatement or renewal the ship is considered tohave been lost the Register class.

The class may be suspended for a period of nomore than six months.

2.1.8 The class of a ship is withdrawn by theRegister in the following cases:

.1 upon expiration of the maximum term of classsuspension;

Part I. Classification 19

.2 when the Register and/or shipowner considerreinstatement of the class suspended as stated in 2.1.6to be impossible;

.3 upon transfer of the ship to the class of anotherclassification body;

.4 at the request of the shipowner.Withdrawal of the ship's class means cessation of

the Classification Certificate validity.2.1.9 The class of a ship shall be cancelled due to

her loss or scrapping.2.1.10 After assigning the class the Register intro-

duces the sea-going self-propelled ships and self-propelledmobile offshore drilling units of 100 gross tonnage andupwards into the Register of Ships and excludes them incase of withdrawal or cancellation of a class. When thevalidity of a class is suspended, appropriate entry shall bemade in the Register of Ships indicating that the validityof a class is suspended up to the stated date.

2.2 CLASS NOTATION OF A SHIP

The class notation assigned by the Register to aship or floating facility consists of the character ofclassification and additional distinguishing marksand descriptive notations defining structure andpurpose of a ship or floating facility.

The sequence of distinguishing marks anddescriptive notations (if any) being added to thecharacter of classification of a ship is set down by theprovisions of this Chapter as well as by relevantprovisions concerning the class notation included inrules for the classification and construction of shipsof special types, as listed under 1.2.2.

2.2.1 The character of classification assigned bythe Register to a ship or floating facility consists ofdistinguishing marks:

KM>, KM#, (KM)# _ for self-propelled shipsand floating facilities;

KE>, KE#, (KE)# _ for non-self-propelledships and floating facilities with total power output ofprime movers 100 kW and upwards;

K>, K#, (K)# _ for other non-self-propelledships and floating facilities.

2.2.2Depending on the Rules on the basis of whicha ship or a floating facility was surveyed, and theclassification body which carried out the survey, thecharacter of classification is established as follows:

.1 ships and floating facilities built according tothe Rules of and surveyed by the Register areassigned a class notation with the character ofclassification: KM> or KE> or K> (see 2.2.1);

.2 ships and floating facilities which were as a whole(or their hull or machinery installation, machinery andequipment) built and/or manufactured according to the

Rules of another classification body recognized by theRegister and surveyed by that body during theirconstruction and manufacture, when classed with theRegister are assigned a class notation with the characterof classification: KM#, KE# or K# (see 2.2.1);

.3 ships and floating facilities which were as a whole(or their hull or machinery installation, machinery andequipment) built and/or manufactured without beingsurveed by a classification body recognized by theRegister or without any survey of a classification bodyat all, when classed with the Register, are assigned aclass notation with the character of classification:(KM)# or (KE)# or (K)# (see 2.2.1);

.4 ships and floating facilities for which theirdesign does not permit the main class notation out ofthose listed in 2.2.2.2 to be assigned a class with thecharacter of classification: KM# or KE# or K#.

This also applies when a ship or floating facilitieschanges a class to the Register from one of the IACSMember Societies. The possibility of such a change isconsidered in each case by the Register Head Office.

2.2.3 Ice category marks.2.2.3.1 Ice category marks are assigned to

icebreakers and ice ships.2.2.3.1.1 I c e b r e a k e r s are specialized ships

intended for all kinds of icebreaking operations:escort of ships in ice, surmount of ice ridges, breakingof a navigable channel, towing, breaking of ice andrescue operations. There are two main regimes of icenavigation while performing icebreaking operations:continuous motion and ramming.

2.2.3.1.2 I c e c l a s s s h i p s are ships intendedfor inde-pendent ice navigation including motion infractures between floes, surmounting of ice isthmusesand portions of relatively thin compact ice, ornavigation in ice with icebreaker escort.

2.2.3.1.3 The following definitions are used forthe description of ice navigation conditions:

i c e c o n c e n t r a t i o n is a measure of icecontinuity, which is characterized by the ratio ofthe area covered by ice to the total water area using10 number scale;

o p e n f l o a t i n g i c e is ice of concentration 4to 6, where most of the floes do not touch each other;

c l o s e f l o a t i n g i c e is ice of concentration 7to 8 where most of the floes touch each other formingice isthmuses;

v e r y c l o s e f l o a t i n g i c e is ice of concen-tration 9 or over, but less than 10;

c o m p a c t i c e is ice of concentration 10.2.2.3.2 If an icebreaker complies with the

requirements of the Rules, one of the following icecategory marks is added to the class notation: ll6;ll7; ll8; ll9.

Icebreakers of the above categories have thefollowing tentative service characteristics:

20 Rules for the Classification and Construction of Sea-Going Ships

ll6 _ intended for ice breaking operations inharbour and roadstead water areas as well as in non-arcticfreezing seas where the ice is up to 1,5 m thick. Continuousmotion capability in unbroken ice up to 1 m thick;

ll7 _ intended for ice breaking operations inthe arctic seas on coastal routes during winter/springnavigation in ice up to 2,0 m thick and summer/autumn navigation in ice up to 2,5 m thick; in non-arctic freezing seas and mouths of rivers flowing intoarctic seas in ice up to 2,0 m thick. Continuousmotion capability in unbroken ice up to 1,5 m thick.The total shaft power not less than 11 MW;

ll8 _ intended for ice breaking operations inthe arctic seas on coastal routes during winter/springnavigation in ice up to 3,0 m thick and summer/autumn navigation without restrictions. Continuousmotion capability in unbroken ice up to 2,0 m thick.The total shaft power not less than 22 MW;

ll9 _ intended for ice breaking operations oncoastal routes in arctic seas during winter/springnavigation in ice up to 4,0 m thick and summer/autumn navigation without restrictions. Continuousmotion capability in unbroken ice over 2,0 m thick.The total shaft power not less than 48 MW.

2.2.3.3 Categories of ice class ships.

2.2.3.3.1 If a self-propelled ship complies with therelevant requirements of the Rules, one of thefollowing ice category marks shall be added to itsclass notation: lu1, lu2, lu3, lu4, lu5, lu6,lu7, lu8, lu9. Ice category marks need not beadded to the class notation of non-self-propelledships.

2.2.3.3.2 Categories lu1, lu2, lu3 which formthe group of non-arctic categories refer to shipsintended for navigation in freezing non-arctic seas(non-arctic ships).

2.2.3.3.3 Categories lu4, lu5, lu6, lu7,lu8, lu9 which form the group of arctic categoriesrefer to ships intended for navigation in arctic seas(arctic ships).

2.2.3.3.4 For tugs, depending on the compliancewith the appropriate ice category requirements, oneof the following marks is added to the class notation:lu2, lu3, lu4, lu5.

2.2.3.4 Averaged quantitative data on permittedservice areas and ice service conditions presented inTables 2.2.3.4-1 to 2.2.3.4-3 shall be used whenchoosing the ice category of arctic ships. It is notpermitted to use these data for regulating theallowable navigation conditions of ships in service.

T a b l e 2.2.3.4-1Service areas and conditions for ships of arctic categories

Part I. Classification 21

It is assumed that during service the owner will followthe requirements of the Ice Certificate or anotherdocument specifying the conditions of safe operationof the ship in ice depending on the ice category mark,the ship's specific features, ice conditions and ice-breaker escort.

Table 2.2.3.4-1 shows service areas for ships inthe Russian arctic seas (the Barents Sea, the KaraSea, the Laptev Sea, the East-Siberian Sea, theChukchee Sea) in relation to the season, tactics ofice navigation and type of navigation.

Table 2.2.3.4-2 shows, for arctic category ships,limiting type and thickness of ice enabling a ship tonavigate in a channel following an icebreaker at a lowspeed (3 to 5 knots) without running a heightenedrisk of damage through contact of hull with ice.

Table 2.2.3.4-3 shows, for arctic category shipsoperating independently, permissible speeds which aship under the ice conditions set out in the table may

reach when navigating in fractures between floes orsurmounting ice isthmuses without running a heigh-tened risk of damage through contact of hull with ice.

2.2.3.5 When choosing the category of icestrengthening for non-arctic ships, it is recommendedto use mean values of permitted conditions of icenavigation set forth in Table 2.2.3.5.

2.2.3.6 Arctic ships may navigate in non-arcticfreezing seas in ice conditions corresponding to thosestated in 2.2.3.4-2 and 2.2.3.4-3.

2.2.3.7 In Table 2.2.3.7 an attempt has been made tocorrespond the ice category marks of the present Rulesto those of the Rules, edition 1995. The provisions of2.2.3.4 to 2.2.3.6 do not apply to the ships builtaccording to the Rules, edition 1995 and earlier.
