This paper presents the effect of surging motion on viscous flows around a Wigley ship running in incident waves through CFD simulation. The computational method used is based on the Navier-Stokes equations in unstructured grid system with pseudo-compressibility assumption. Since a ship changes its attitude when it runs in incident waves, we have to modify the code to be able to treat the ship motion by use of a moving grid technique. In order to simulate surging motion, the ship is connected with a spring to keep its mean position. We show the influence of surging motion on wake and ship resistance using springs of different strengths. Numerical results and discussions are shown.
