NUMERICAL MODELLING OF LOCAL SCOUR BELOW OFFSHORE PIPELINES. This research will develop a numerical model for time-dependent local scour below offshore pipelines subject to steady currents and waves. No such model is currently available in the offshore oil and gas industry and the research community. Instead, design engineers have to use simple empirical formulae to estimate the scour potential in complex environmental conditions. This may result in unsafe or over conservative designs. Therefore the model developed in this project will have direct impact on the stability design of offshore pipelines. The design will be safer and more reliable, and improved design may lead to a reduced cost.
