By using two different three-dimensional source distri- bution techniques, three-dimensional translating-pulsating source (3DT) and three-dimensional pulsating source (3DP), numerical investigations have been carried out for a high speed monohull ship (RD-200) advancing in oblique waves. The numerical results are compared with experimental values obtained from wave load tests carried out at the SSPA. These extensive test results cover different wave directions at a wide range of wave frequencies.
