COMPUTATION OF RELATIVE MOTION EFFECTS IN OFFSHORE SUPPLY OPERATIONS

Using currently available computer programs for computing the wave induced motion of ships and stable platforms it is now possible to make good predictions of vessel absolute and relative motion in both regular and random waves. It remains only to combine these computations for typical supply boats and semi-submersibles to determine the relative vertical motion between say the platform crane boom and the after deck of the supply boat. The computation then provides a good basis for answering several design and operational questions such as: Optimum size of supply vessel. Limiting sea states. Comparisons of conventional vs. semi-submersible supply vessels. Some results are given of parametric studies of supply vessel size and proportions in various sea states.
