Sažetak
When a ship is damaged, the operators need to decide on immediate repair actions by evaluating the effects of the damage on the safety of the ship using residual strength assessment procedures. Safety assessments are usually performed with respect to the ultimate vertical bending moment capacity assuming upright position of damaged ship. However, floating conditions of damaged ship could be changed dramatically resulting in change of the draught and trim and also inducing the important heeling angle. In case of the ship heeling the bending moment can be decomposed in two components, one perpendicular and other one aligned to the neutral axis of the intact ship. The problem is equivalent as considering upright damaged section loaded by combined vertical and horizontal bending moments. Such problem is commonly approached by nonlinear interaction equation between vertical and horizontal bending moments. The aims of the present paper are firstly to review literature with such interaction equations published and then to apply one of them on the example of damaged tanker loaded by combined bending moments caused by the heeling angle. The purpose is to evaluate importance of the heel on the structural safety of damaged ship.
