FOREWORDDNV GL rules for classification contain procedural and technical requirements related to obtainingand retaining a class certificate. The rules represent all requirements adopted by the Society asbasis for classification. DNV GL AS January 2017Any comments may be sent by e-mail to rules@dnvgl.comIf any person suffers loss or damage which is proved to have been caused by any negligent act or omission of DNV GL, then DNV GL shallpay compensation to such person for his proved direct loss or damage. However, the compensation shall not exceed an amount equal to tentimes the fee charged for the service in question, provided that the maximum compensation shall never exceed USD 2 million.In this provision "DNV GL" shall mean DNV GL AS, its direct and indirect owners as well as all its affiliates, subsidiaries, directors, officers,employees, agents and any other acting on behalf of DNV GL.

This document supersedes the October 2015 edition of DNVGL-RU-SHIP Pt.2 Ch.1.Changes in this document are highlighted in red colour. However, if the changes involve a whole chapter,section or sub-section, normally only the title will be in red colour.Amendments July 2017 Sec.1 General— Sec.1: Content in Sec.4 (references, abbreviations and symbols) moved to Sec.1. Sec.4 deleted. Sec.2 Manufacture, survey and certification— Sec.2 [2.1.1]: Abbreviation HWA deleted, because approval for heat treatment workshop will be coveredby appropriate approval as AMM.Main changes January 2017, entering into force 1 July 2017 Sec.2 Manufacture, survey and certification— Sec.2 [2.1]: Description of WWA amended. Covering of WWA and HWA by AoM included.— Sec.2 [3.2.5]: Including of CET formula to be alternatively used for VL460 and higher grades incompliance with IACS UR W 16 Sec.3 Testing procedures— Sec.3 [3.1.8]: Including of information for alternative test specimen for tensile testing of thick plates incompliance wit IACS UR W 16— Sec.3 [3.2.5]: Wording amended for dimensions of Charpy V-notch specimens— Sec.3 [3.3]: Including of dimensions of bend test specimen for cast steel, forgings and semi-finishedproductsEditorial correctionsIn addition to the above stated changes, editorial corrections may have been made.Rules for classification: Ships — DNVGL-RU-SHIP Pt.2 Ch.1.
