Abstract
A series of numerical simulations are performed to investigate the dynamic response of J-tube submarine cable around monopile foundation. The variations of maximum curvature, maximum effective tension and motion amplitude with incident angle, significant wave height, current velocity and suspended length are analyzed. The results show that as the significant wave height and current velocity increase, the maximum curvatures at both ends of submarine cable increase. Moreover, the maximum curvature and effective tension significantly increase with the increase of suspended length. Different protection methods for the J-tube submarine cable are investigated to reduce the risks of curvature and bending failures. It is found that the riprap-concrete mattress combined protection can effectively reduce the maximum curvature and motion amplitude of J-tube submarine cable.
