... Abstract In order to predict manoeuvrability of ships in seaways a mathematical model for approximating the hydrodynamic forces acting on the ship has been extended for taking into account mean forces and moments due to waves. RANS computations for a twin screw passenger ship in waves...

... determined. The theoretical and computer simulated mean force, force density spectra, coherency test and extraction of low frequency force were performed. INTRODUCTION For analyses of offshore structure designs, applications of 2"d-order theories have recently been being increased. On the other hand...

... that reliable results can be obtained even with 152 total higher-order boundary elements. While vertical-plane motions are almost negligible in the actual TLP condition, the mean force results are close to those of the freely~floating condition due to the weak resistance of the tendons against the horizontal...

... with analytic solutions and axisymmetric results. HOBEM is shown to be efficacious especially for the computation of body-surface velocities and velocity potential and its derivatives on the waterline and related integrals. For illustration second-order mean forces and wave run-up on vertical circular cylinders...
