.... However, most of recent researches about the hydrodynamic performance of ships in waves focus on the added resistance, and the experimental or numerical data on the propulsion performance considering the ship motion in waves is very rare. In this paper, numerical investigation on the nominal wake...

... ABSTRACT This paper studies the estimation of added resistance of ships in both head and oblique waves using an asymptotic formula in short waves. The enhanced asymptotic formula, which was introduced only for head waves by Yang et al. (2018), is extended for oblique waves. A new correction...
