The following features are included: simplified calculation of residual curvature for inner and outer pipes; separate rotation for each pipe; distributed contact force between the two pipes and interpipe friction. Results are presented from sensitivity...

... ABSTRACT In the process of a wave moving from deep to shallow water, because of shoaling, refraction, friction, and other effects, wave deformation in shallow water appears when the depth is shorter than half the wavelength. As a result, the wave celerity slows down, the wave length become...

... ABSTRACT A simplified method to estimate the impact force in ship bow-iceberg collisions is presented. The eccentricities of both iceberg and ship are included. The friction at the contact point is also included so that the sliding effect is taken into account. The impact force is determined...
