Experimental and numerical studies on linear and nonlinear seakeeping phenomena of the DTC ship in regular waves

Abstract

The paper presents a comprehensive numerical and experimental study on linear and nonlinear seakeeping phenomena, including six degree of freedom (DOF) ship motions, added resistance, drift forces and moments of the DTC containership in regular waves. Obtained numerical results by the 3D panel method NEWDRIFT+ of NTUA-SDL are systematically compared with corresponding experimental data generated within the SHOPERA project (2013–2016) at MARINTEK for various wave headings at low to moderate speeds. The herein presented experimental data are useful not only for validating the employed seakeeping software and others as a benchmark yardstick, but also for the deeper analysis of various open nonlinear seakeeping issues encountered in the prediction of the added resistance and drift forces of modern large containerships in waves.
