Development of "Stability Recovery System" that Maintains Ship Stability at the Time of Damage - Ensuring Cargo Loading Capacity and Easing Restrictions on the Hull Form -
Due to the recent introduction of tighter damage stability regulations, requirements on the residual stability under damaged conditions have become increasingly strict. In order to meet the tougher regulations, Mitsubishi Heavy Industries, Ltd. (MHI) has developed a stability recovery system to be installed on Roll‐on/Roll‐off (RoRo) ships, Pure Car & Truck Carriers (PCTCs) and RoPax ferries, to which the new regulations are applied. By equipping these ships with the stability recovery system, in the event that the ship is damaged during the voyage, seawater accumulating in the lower car section is drained into the void space at the ship bottom, quickly lowering the center of gravity and restoring the stability lost as a result of the damage. This Technical Review provides an overview of the stability recovery system, its effects, and the implementation thereof.
