Circular

  1 The Maritime Safety Committee, at its ninety-eighth session (7 to 16 June 2017), adopted resolution MSC.421(98), containing, inter alia, amendments to the SOLAS chapter II-1 subdivision and damage stability regulations. In this regard, one of the amendments removed a provision in regulation II-1/22 that had permitted certain watertight doors to remain open during navigation, if authorized by the Administration.

2 Consequently, the Committee, with a view to providing updated guidance for watertight doors on passenger ships which may be opened during navigation under SOLAS chapter II-1/22 and their impact on the damage stability survivability, approved the annexed Revised guidance for watertight doors on passenger ships which may be opened during navigation, prepared by the Sub-Committee on Ship Design and Construction, at its second session.

3 The Revised guidance contains the following appendix: Floatability assessment.

4 Member States are invited to apply and bring the annexed Revised guidance to the attention of passenger shipowners, operators and all other parties concerned for application to passenger ships constructed on or after the date of entry into force of the associated amendments to SOLAS chapter II-1/22.
