Submarine power cables: laying procedure, the fleet and reliability analysis

摘要

This paper investigates the possible problems of laying submarine power cables (SPC). It provides information about the power cables themselves, the laying procedure, and the respective fleet. It also describes the medium voltage (MV) transmission grid in Greece and determines the correlation of different parameters that affect the operation of the network. Furthermore, a reliability analysis, based on a statistical model, is conducted; the model is used to evaluate the operational characteristics of cables, such as the rate of failures from natural or human causes, and is also used to choose between different candidate cable routes in order to determine the one with the maximum reliability.
