1. A system for transmission of power offshore comprising:
(1) an offshore power distribution station;
(2) a power transmission station; and
(3) high voltage cable system operably connected to (1) and (2);
wherein said high voltage cable system comprises a dynamic, dry type high voltage submarine cable configured to transmit at least about 45 megawatts of power;
wherein at least a portion of the dynamic, dry type high voltage submarine cable is at a water depth of from about 400 up to about 2000 meters;
wherein the dynamic, dry type high voltage submarine cable comprises a conductor, surrounded by a semiconductor wherein the semiconductor is surrounded by an insulator, wherein the insulator is surrounded by a second semiconductor, and wherein the second semiconductor is surrounded by a metallic sheath or a barrier.
