Global wave loads on a damaged ship

A Ship-borne Wave Recorder

On Kelvin ' s ship - wave pattern

When a concentrated pressure travels with constant velocity over the free surface of water, it carries with it a familiar pattern of ship waves. Let viscosity and surface tension be neglected, let the free-surface condition be linearized, let the depth of water be assumed infinite, and let initial transient effects be ignored. Then, as is well known, the wave motion everywhere can be found by s...

Coupling between Flexible Ship and Liquid Sloshing Using Potential Flow Analysis and Its Effect on Wave-induced Loads

In this paper the potential flow approach adopted in previous investigations for the coupling effect between rigid body ship motion and sloshing is extended to the flexible ship-partially filled tank system, using the de-singularised Rankine source method. The unified method is verified by applying it to the sloshing in a partially filled rectangular tank with a flexible wall. The main aim of t...

Damping Wind and Wave Loads on a Floating Wind Turbine

Offshore wind energy capitalizes on the higher and less turbulent wind speeds at sea. To enable deployment of wind turbines in deep-water locations, structures are being explored, where wind turbines are placed on a floating platform. This combined structure presents a new control problem, due to the partly unconstrained movement of the platform and ocean wave excitation. If this additional com...

Numerical Simulation of Damaged Ship Motion in Waves

The coupling motion of heave, pitch and roll of intact ship and damaged ship in waves, and the flow of flood water in damaged tank have been simulated based on viscous theory. The calculation model is a 29000 t tanker model moving at a constant speed with damaged tank in midship area. Three cosine waves including head waves, beam waves and oblique waves are simulated by boundary input method re...
