Cable Selection Methodology for Deep Water Power Transmission System Applications

A methodology has been developed to assist in the technical evaluation of power transmission cable system installation and operational risks and the selection of a cable design for application in deep water installation situations. The methodology involves the evaluation of eight defined technical selection criteria that provide either (1) an index of safety associated with various technical design aspects of a "Candidate" cable, or (2) an indication of the technological difficulty to manufacture, install, repair or operate each cable "Candidate." The cable selection methodology was developed to support the needs of a specific transmission cable application in Hawaii, but the methodology should be readily adaptable to other submarine power cable projects.
