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.
