The equations of motion for the coupled dynamics of a long flexible life raft and fast rescue craft in an irregular ocean wave are formulated in two dimensions using the methods of Kane and Levinson (Dynamics: Theory and Applications, McGraw Hill Inc

The longline is modelled using lumped masses and tension-only springs including structural damping. The mussel culture is modelled as cylinders attached to the main line and the equations are formulated for the coupled dynamics of the main line, buoy

The equations governing the boom-assisted deployment of a lifeboat from a moving support are formulated in three dimensions using Kane's method, accounting for the coupling of the dynamics of the boom and lifeboat. The effect of wind loading is inclu

Impact forces between small bodies colliding in a regular wave are estimated using the contact theory of Hertz and an elastoplastic model due to Lankarani and Nikravesh (1994) . To determine the relative impact speed, the equations of motion for the

The equations of motion of a freefall lifeboat are formulated using Kane’s method. Deployment from a moving ramp is assumed to occur in a known plane and a 2D model suffices. A segmented approach is used to model ramp contact. A separate 3D model i

The effect of wave forces on the stability of a sloping seabed is investigated, using linear wave theory and Biot's theory of poroelasticity. The wave forces on the slope, the wave induced effective stresses and pore pressures are all computed by the
A lumped-mass model of a marine evacuation chute is presented based on the equations of Kane. The effects of wind load, internal mass transport and the motions of the ends are included. A sample of predicted motions and tensions is presented for a ty

A tether management system of a winch module in a marine environment is proposed. For the purpose of this study the subsea body is considered as a mass attached at the free end of a long tether which is wrapped around a circular drum controlled by an
