SECTION 1 CLASS NOTATIONS

1 General

1.1 Introduction

1.1.1 All vessels classed with the Society may be assigned

— construction symbol— main class notation— ship type notation— additional Class Notation— service area notation

as applicable.

1.1.2 Class notations are assigned in order to determine applicable rule requirements for assignment andretention of class. Applicable class notations are given in Sec.2 to Sec.5.

1.1.3 Class notations are either mandatory or optional. The mandatory class notations are indicated in theTables given in Sec.2 to Sec.5.

1.1.4 In accordance with Ch.1 Sec.1 [2.2.5] optional class notations from the Society's other rule booksmay, upon special consideration, be assigned to a vessel complying with those rules.

1.1.5 Class notations may be given one or more qualifiers which are supplementary symbols used to identifyvariants of the class notation or a design parameter. Qualifiers typically denote differences in levels ofcomplexity and/or special requirements or limitations, and may be assigned additional requirements.Qualifiers follow immediately after a class notation and are indicated in parenthesis. Multiple qualifiers areseparated by comma and space.

1.1.6 Class notations and qualifiers are shown in bold. See Table 1 for examples of class notations andqualifiers.

1.1.7 The Tables in Sec.2 to Sec.5 include the following information:

— name of class notation— indication of class notation being mandatory— reference to design requirements*— reference to survey requirements for Fleet in Service (FiS)*)— qualifiers as relevant— purpose of class notation— application, giving additional information on when and/or where a class notation can be applied and/or

under what condition a class notation is mandatory.

* NA indicates no requirements.

SECTION 2 CONSTRUCTION SYMBOL AND MAIN CLASS NOTATION

1 Construction symbols

1.1 General

1.1.1 The construction symbol ✠ will be assigned to vessels built under the supervision of the Society.

1.1.2 The construction symbol will be assigned to vessels built under the supervision of a classificationsociety recognized by the Society and later assigned class with the Society. For such vessels the classnotations which the Society considers to have the equivalent intent will be assigned.

1.1.3 Vessels other than those described in [1.1.1] and [1.1.2] will not be assigned a construction symbolwhen classed with the Society.

2 Main Class Notation

2.1 General

2.1.1 The main class notation 1A will be assigned to vessels with hull, machinery, systems and equipmentfound to be in compliance with applicable rule requirements as given in Pt.2, Pt.3 and Pt.4.

2.1.2 The main class notation 1A will also be assigned to vessels designed and constructed in accordancewith the rules of another classification society, and later assigned class with the Society.

SECTION 3 SHIP TYPE NOTATIONS

1 Introduction

1.1 General

1.1.1 Vessels that comply with requirements defined in Pt.5 may be given a ship type notation as indicatedin Table 1 to Table 13 of this section.

1.1.2 A vessel may be assigned more than one ship type notation provided that the respective requirementsare met.

1.1.3 Certain ship type notations are mandatory based on e.g.:

— type of cargo— number of passengers— the ability to execute special operations.

1.1 General

1.1.1 The service area notation R followed by a number or a letter will be assigned to vessels with modifiedrequirements to arrangement, equipment or scantlings, in relation to vessels built for unrestricted trade.The service area restrictions, given in nautical miles and representing the maximum distance from nearestport or safe anchorage, are given in Table 1 of this section. For the various service area notations therestrictions are related to the zones, areas and seasonal periods as defined in the International Conventionon Load Lines, 1966, Annex II.The service area notation RE is limited to enclosed waters such as fjords, ports, rivers and lakes.The service area restrictions as related to the assigned service area notation will be included in the “Appendixto the Class Certificate”.

1.1.2 Modified requirements related to the various service area notations are given in the relevant sectionsof the rules. The modifications will affect:

— design hull girder loads— design pressures on shell, weather decks, superstructures and deckhouses— anchoring and mooring equipment— arrangement— stability.1.1.3 The flag administration, the domestic requirements of which are being applied under the provision ofCh.1 Sec.2 [1.3.5] (local trade), shall be indicated in parentheses after the service area notation, by usinglower-case country codes in accordance with ISO 3166, (e.g. R2 (nor), should the flag administration beNorway or R2 (usa) should the flag administration be U.S.A. etc.).1.1.4 Other service restrictions or operational limits included in the design assumptions for a vessel will bestated in the “Appendix to the Class Certificate”, and/or on special signboards.
