The traditional forward speed seakeeping problem was extended to consider the ship with a drift angle. A computer code was developed based on a time domain Rankine panel method. Once the velocity potential around the hull was determined, the first order wave induced motions were calculated and then the second order wave drift forces were evaluated using a near field method. Based on the developed code, the longitudinal and transverse steady wave drift force, as well as the steady yaw moment were computed for a container ship in head and beam waves. The effects of the drift angle on the steady wave drift forces were included and discussed. The numerical results were compared with the published experimental measurements, which shows fairly good agreement.enhttp://rightsstatements.org/vocab/InC/1.0/Drift angleObliquely moving shipRankine panel methodSecond order wave effectWave drift forceTechnikIngenieurwissenschaftenConference Paper10.15480/882.332910.15480/882.3329Fluiddynamik und Schiffstheorie M-8Conference Paper
