Seakeeping experiments on damaged ship

The aim of this paper is to present results of seakeeping experiments performed on a damaged ship hull and to compare them with numerical analysis results. The assumed damage opening in the ship hull, i.e. the damage extent, is determined based on probability distribution functions for damage size and location as specified by the Marine Environment Protection Committee. Two different sets of experiments are conducted in a large commercial towing tank. Firstly, rigid body motions of damaged and intact ship hulls in tow in head seas with small forward speed are measured for irregular waves. Secondly, ship motions and vertical wave bending moments are measured on the segmented model in regular waves. Experimental results are compared with the linear 3D Boundary Element Method using Hydrostar software. Satisfactory correlation of computations and experiments is achieved for ship in tow while discrepancies are found for the segmented model. An important finding of this experimental campaign is that measured vertical wave bending moments of the damaged ship considerably exceeds those of the intact ship.
