Ship cabin damage mode identification arithmetic base on seawater ingress process

The seawater ingress sensors in cabins will be damaged when the ship is attacked on sea. And it is difficult for damage control monitors to accept the cabin flooding signals, so it is uneasy to judge which cabins are flooded for crews. Accordingly, it is necessary to set up an arithmetic to identify the flooded cabins, which only depends on ship poise signals in flooding process but not on the cabin flooding signals. Firstly, the generation arithmetic of the ship´s damage modes is set up by the width priority searching and back tracking method. Secondly, the identification course is analyzed, and the identification model of cabin damage modes is set up by gray relation theory associating with the above generation arithmetic. Lastly, one ship damage mode is identified, and its calculation result shows that the identification arithmetic is accurate.
