This report describes the development of an assessment process to accurately predict the survivability of a corrosion-degraded ship in specific wave conditions. The method developed utilizes a ship specific 3-D hydrodynamic model to simulate the ship’s rigid body dynamic response to wave conditions, measuring the resulting ship motions and pressure distribution on the hull. Pressure and acceleration data from the hydrodynamic model is then input into a 3-D finite element model of the degraded ship structure where the resulting stresses in stiffeners and plating are assessed against various failure modes, including buckling modes, which are calculated according to IACS Common Structural Rules. The results form the basis of a degraded ship strength assessment which can be provided to a ship owner and operator to make operational and repair decisions.
