Riser Segment Design of Underwater Electric Power Transmission Cable System. Final Report, September 9, 1977-September 30, 1978

摘要

The transmission of electrical power from OTEC generating plants to shore-based power grids requires riser cables that connect the OTEC plant and the bottom cable. The ocean depths anticipated will far exceed the maximum that is the limit of previous high voltage power cable experience. Due to the unique ocean suspension required for these cables, they will also be subjected to motions and forces that have never before been imposed on a high voltage power cable. In view of these factors, this study has examined riser cable support systems, candidate cable types, terminations and connections, installation, maintenance and repair of the system, cost, and overall reliability. Requirements for further development work have also been addressed. None of the problems defined in this study appear to be insurmountable and it is expected that the Phase II development effort will yield viable riser cable system designs. (ERA citation 05:017533)
