In this study, a protection-pipe system is developed for the protection of undersea electricity power cable laid along shoreline with medium deep water. The protection-pipes are made from ductile cast-iron alloys while the dimensions are designed corresponding to the diameter of balk electricity power cables. In order to know if the protection-pipe is strong enough to prevent the power cable from damages caused unnaturally, such as berthing anchoring from large size ships or towing operation from fishing boats, both analytical and experimental studies were carried out. Presented in this paper is an analytical study based on the material mechanics. A finite element analytical method was applied and the deformed shapes on the protection-pipe were studied. Along with the deformation, the corresponding stresses were also presented. In order to know the response of the protection-pipe subjected to an impact loading exerting on various parts of the pipe, several analysis for various loadings and boundary conditions were performed. It was found from the results of the analysis that the proposed protection-pipes are able to meet the requirements of TPC set for the electricity power cable laid under seawater.
