英文释义

A practical method of presenting the impact of damage on the ship’s stability developed for passenger vessels by Three Quays Marine Service. The damages are presented by compartments, defined by transverse watertight bulkheads and the illustration presents a quantitive indication of survability for each case. Compartmental damages are further divided by transverse and vertical extent, namely: (1)transversely to either the B/5 line or to the centreline, (2) vertical extents covering either baseline upwards or from tank-top upwards. The results illustrate sequential damage situations for one, two, and three compartments, thus covering scenarios within and in excess of statutory requirements. To aid interpretation, the damage uses a traffic light” colour code, with either a red, yellow, or green background, reflecting the severity of the damage. The colour system represents the following results: (1) green: 100% of damage stability criteria satisfied (2)yellow: 25%-99% of damage stability satisfied (3) red: less than 25% of damage stability satisfied. With DCD a ship staff are able to gain a thorough understanding of their ship survival capabilities, allowing them to prepare their damage control in advance
