Abstract: The latest regulations of the assumed damage range and the damage location of the high-speed ship are summarized by comparing the damage stability criteria for the high-speed ship in the Domestic Statutory Inspection Technical Rules (2011) (2011 Regulations) and the Domestic Statutory Inspection Technical Rules (2020) (2020 Regulations). The damage stability results and the improved solution are analyzed based on the calculation cases. Measures are proposed to reduce the water inflow, reduce the damage waterline and increase the maximum residual righting lever. It can provide reference for the overall optimization design of the same type of coastal high-speed passenger ships.

Key words: high-speed passenger ship, damage stability, damage range, watertight separation, buoyancy tank, weather tight point
