MHI system can improve stability

摘要

Mitsubishi Heavy Industries (MHI) has leveloped a system to improve the stability of ships and reduce the risk of capsizing in the event of the hull being penetrated. The so-called 'righting moment recovery system' was created in response to tighter SOLAS regulations on ship stability introduced for RORO ships, pure car and truck carriers and ferries in January 2009. If the ship's hull sustains damage, the system circulates seawater into void spaces in the ship's bottom. This reduces capsizing risk by quickly lowering the ship's centre of gravity and thereby letting the vessel right itself.
