1 Introduction

  1.1 This floatability assessment is only for the purpose of determining the impact of open watertight doors on ship survivability under SOLAS regulation II-1/22.4 (previous SOLAS regulation II-1/15.9.3). It is intended that this floatability assessment be applied only after the need for a watertight door(s) to remain open during navigation is established.

  1.2 Care should be exercised not to confuse the "floatability assessment" criteria used in this procedure (for determining the impact of open watertight doors on survivability) with the requirements in the SOLAS chapter II-1 damage stability regulations.
