English: CSIRO scientists have created 'rogue waves' more than 20 metres high and smashed them into virtual oil and gas production platforms to compare different mooring designs. The computer modelling project compares how different types of semi-submersible oil rigs withstand the effects of giant waves in the open ocean. Rogue waves are rare, extreme events that pose a risk to shipping and offshore structures and can lead to loss of life. CSIRO is using fluid-flow mathematics and computer modelling to assist in the sensible and safe design of oil platforms. The mathematical technique used is called Smoothed Particle Hydrodynamics and was originally developed in astrophysics to model stars forming and galaxies exploding.
