DETERMINATION OF CAPSISING SAFETY OF DAMAGED SHIPS BY MEANS OF MOTION SIMULATIONS IN WAVES

A numerical method is presented for simulating the motions of a damaged ship in an irregular seaway and for computing the capsising probability during a given time. The author is mainly interested in following and head seas because of the oscillations of the righting levers caused by the passage of waves along the ship. Computations carried out for an example ship show that the internal fluid acts as a very effective roll damping mechanism. It is shown that a damaged ship subdivided in accordance to the damage stability requirements of the German Navy can be safe during a period of time in the order of magnitude of days even in extremely severe seaways.
