A new strip theory is presented for predicting heave, pitch, sway, roll, and yaw motions as well as wave-induced vertical and horizontal shear forces, bending moments, and torsional moments for a ship advancing at constant speed with arbitrary heading in regular waves. A computer program based...

The method was used to solve the linearized ship motions and sea loads for a ship with a steady forward speed in quasi-random incident waves. The solution algorithm involves the discretization of the ship hull and part of the free surface by panels, over which a B-spline approximation is ...
'Ship motion' refers to the various movements experienced by a ship at sea, including sway, surge, roll, pitch, and yaw. These motions are influenced by factors such as currents, water levels, and the ship's own oscillations. AI generated definition based on:Ocean Engineering,2010 ...
Moreover, tank model tests and a large-scale model sea trial are comparatively conducted to validate the difference between ship response and statistics in long- and short-crested irregular waves. Results The results show that when navigating against the waves in the same sea condition, the ...

This period is so long compared with the impact duration for normal ships and installation structures that the motions and thus the restoring forces during the impact can be neglected. Then, the impact energy released for crushing can be determined from Eq. (2.37): Eξ=12Ma1+max1+Ma1+maxMb...
