This project aims to improve predictions of hydrodynamic forces on small submarine cables and pipelines through comprehensive experimental modelling at 1:1 scale coupled with development of predictive numerical models. The focus will be on forces in unsteady flows. Present industry guidelines do not make allowance for potential reductions in forces for small diameter pipelines whose diameters are a similar length to the effective seabed boundary layer, thereby leading to overly conservative and costly stability design. Results from the experimental program and numerical model developed are expected to be used to improve the current industry design guidelines.

该项目旨在通过1：1比例的综合实验模型以及预测性数值模型的开发，改进对小型海底电缆和管道上的水动力的预测。重点是非定常流中的力。目前的行业指南没有考虑到小直径管道的力的潜在减少，这些管道的直径与有效海底边界层的长度相似，从而导致过于保守和昂贵的稳定性设计。从实验程序和数值模型开发的结果，预计将用于改善目前的工业设计准则。
