1 The Maritime Safety Committee, at its eighty-second session (29 November to 8
December 2006), approved Guidelines on alternative design and arrangements for SOLAS
chapters II-1 and III, developed to provide further guidance on SOLAS regulations II-1/55 and III/38, which were adopted by resolution MSC.216(82) and entered into force on 1 January 2009.
2 The Guidelines serve to outline the methodology for the engineering
analysis required by SOLAS regulations II-1/55 and III/38 on Alternative design and arrangements, applying to a
specific engineering or life-saving system, design or arrangements for which the
approval of an alternative design deviating from the prescriptive requirements of SOLAS chapters II-1 and III is sought.
3 The Maritime Safety Committee, at its 101st session (5 to 14 June 2019),
approved amendments to the Guidelines on alternative design and arrangements for
SOLAS chapters II-1 and III (MSC.1/Circ.1212), prepared by the Sub-Committee on
Ship Systems and Equipment, at its sixth session.
4 Member Governments are invited to bring the revised Guidelines set out in
the annex to the attention of shipowners, shipbuilders and designers for the
facilitation of design within the framework of SOLAS regulations II-1/55 and III/38.
