Introduction

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.

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

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

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

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. Qualifiers follow immediately after a class notation and are indicated in parenthesis. Multiple qualifiers are separated by comma and space.

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

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.
