Estimation of the drift forces and added resistance in waves of the KVLCC2 tanker

Abstract

The present research explores different numerical techniques for the estimation of the drift forces, the yaw moment and the added resistance of ships in waves. The estimation of these forces and moment is of interest for a variety of marine engineering applications, including the numerical simulation of the maneuvering of ships in adverse weather conditions. The numerical tools to estimate these forces and moment herein are an in-house 3D panel code based on potential theory, namely NEWDRIFT and a CFD URANS commercial solver. Obtained numerical results for the KVLCC2 standard tanker ship are compared with available experimental data from the EU funded project SHOPERA. The paper critically assesses the potential of the employed numerical methods, while the obtained results are generally satisfactory for practical applications.
