Global strength evaluation with design oblique waves criteria for a 100000 tdw tanker

Abstract

Among the preliminary ship’s evaluation steps, the global strength of the ship’s hull by design oblique wave’s criteria is required from the classification society’s construction rules. A 100000 tdw tanker is selected for evaluation, with two loading cases. The analysis is applied on a ship hull beam model, using own program software P_QSW, with three parameters non-linear equilibrium procedure. Significant oblique design waves are considered, corresponding to maritime operation cases. The global strength results at preliminary design steps are assessed by rules admissible values, so that the ship’s global strength design restrictions are obtained.
