Seakeeping Experiments on Damaged Ship
The aim of this paper is to present results of the seakeeping experiments performed on damaged ship hull and to compare them with numerical analysis. Assumed damage opening in the ship hull, i.e. damage extent is determined based on probability distribution functions for damage size and location as specified by the Marine Environment Protection Committee. Two different set of experiments are conducted in the large commercial towing tank. Firstly, rigid body motions of damaged and intact ship hull in tow in head seas with small forward speed are measured for the irregular waves. Secondly, ship motions and vertical wave bending moments are measured on segmented model in the 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 segmented model. Important finding from this experimental campaign is thart measured vertical wave bending moments of damaged ship considerably exceeds those of the intact ship.
