SECTION 1 CLASS NOTATIONS
A. General A 100 Class notations 101 Class notations are assigned in order to determine applicable rule requirements for assignment and retention of class. Class notations cover mandatory and optional requirements (see Table A1). 102 Applicable class notations are given in Tables B3 to B6 (mandatory notations) and Tables C1 to C7 (optional class notations). 103 Class notations may be given one or more qualifiers which are supplementary symbols used to identify variants of the class notation or a design parameter. Qualifiers typically denote differences in levels of complexity and/or special requirements or limitations, and may be assigned additional requirements. 104 The presentation of class notations in certificates and documents issued by the Society, in the Register of Vessels and in electronic customer portals and user interfaces may differ from the presentation in the rules. Reference is made to DNV GL rules for classification DNVGL-RU-0050 Sec.3[1.5]. 105 Examples of typical class notations as defined in these rules are shown in Table A2. 106 Class notations with no specific survey requirements are marked with N/A in Tables B3 to B6 and Tables C1 to C7.

B. Mandatory class notations B 100 General 101 All ships being assigned class with the Society will be given a class notation consisting of a construction symbol, a main character of class, service area restriction notations and main ship type notations, as applicable. B 200 Construction symbols 201 The construction symbol @ will be assigned to ships built under the supervision of the Society. 202 The construction symbol @· will be assigned to ships built under the supervision of a recognized classification society and later assigned class with the Society. For such ships the class notations which the Society considers to have the equivalent intent will be assigned. 203 Ships other than those described in 201 and 202, will not be assigned construction symbol when classed with the Society. B 300 Main character of class 301 The notation 1A1 will be assigned to ships with hull, machinery, systems and equipment found to be in compliance with applicable rule requirements as given in Pt.2, Pt.3 and Pt.4. 302 The notation 1A1 will also be assigned to ships designed and constructed in accordance with the rules of another classification society, and later assigned class with the Society. B 400 Service restrictions 401 The service area notation R followed by a number or a letter will be assigned to ships with certain modifications to arrangement, equipment or scantlings, in relation to ships built for unrestricted trade. The service area restrictions, given in nautical miles and representing the maximum distance from nearest port or safe anchorage, are given in Table B1. For the various service area notations the restrictions are related to the zones, areas and seasonal periods as defined in the International Convention on 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 “Appendix to the Class Certificate”.

The modifications will affect: — design hull girder loads — design pressures on shell, weather decks, superstructures and deckhouses — anchoring and mooring equipment — arrangement — stability. 403 The flag authority whose domestic requirements are being applied under the provision of Ch.1 Sec.2 A307 (local trade), shall be indicated in parentheses after the service area notation, by using lower-case country codes in accordance with ISO 3166, (e.g. R2 (nor), should the flag authority be Norway or R2 (usa) should the flag authority be U.S.A. etc.). 404 Other service restrictions or operational limits included in the design assumptions for a ship will be stated in the “Appendix to the Class Certificate”, and/or on special signboards. B 500 Modified rule requirements related to size and general arrangement 501 Modified rule requirements related to the size of the ship and its general arrangement are given in Table B2.

A passenger ship is a ship which carries more than twelve passengers. A cargo ship is any ship which is not a passenger ship. 602 A passenger ship will be given the main class notation Passenger Ship or a main ship type class notation given in Table B3. 603 A cargo ship of the types shown in Table B4 will be given the corresponding main ship type class notation. 604 Cargo ships with class notations shown in Table B4 will be amended with a mandatory survey scheme class notation as given in Table B5. 605 Additional mandatory class notations for main ship types arranged and/or strengthened for a special service are given in Table B6. 606 The class notation for main ship types given in Table B3 and B4, may be replaced by alternative ship type class notations as shown in Table C1.
