Design charts for quick estimation of wave loads on damaged oil tanker in the Adriatic Sea

If ship is damaged in collision or grounding accidents, there is a need for rapid evaluation of loads acting on ship hull and residual structural strength in order to plan salvage operation. The aim of the paper is to develop design charts enabling quick assessment of vertical wave bending moments acting on damaged Aframax oil tanker in the Adriatic Sea. Transfer functions are calculated by 3D panel code using added mass method for the response analysis of damaged ship. Response spectrum of vertical wave bending moment is evaluated using Tabain’s wave spectrum, valid for the Adriatic Sea, for different sea states, heading angles and ship’s speed. Response variance is then presented in form of design charts. Discussion how to use design charts for ship in different damage situations is also provided. Although results are applicable for Aframax tanker only, the procedure for development of design charts may be readily employed for oil tankers of different sizes as well as for other ship types.
