Researchers at Cranfield University have recently completed the development of an analysis tool called Wave-X, which is capable of predicting the response of ships and offshore structures to extreme ocean waves.
Based on the use of a technique called Smooth Particle Hydrodynamics (SPH), Wave-X can be used to predict water particle motions near the structure as well as the wave pressures exerted by the fluid on the structure.
This information can be used not only for structural design but also to design the shape of a ship's hull to reduce the dynamic pressures applied to the hull and superstructure.
Cranfield’s engineering team is able to carry out modelling of bespoke designs to allow naval architects to predict how such designs would respond under the impact of extreme waves.
Prof Minoo Patel, head of Cranfield's school of engineering, said: 'The damage caused to ships and offshore structures from extreme waves can be substantial, costing the industry tens of millions of pounds every year. The losses arise from impact damage, green water on deck, cargo loss and even loss of the vessel, yet the only widely available way of designing ships and offshore structures to minimise this damage is through expensive model tests.'
