MOVING A CONDUCTOR THROUGH A CONDUIT BY FLUID PRESSURE

摘要

Electric power transmission to an undersea installation (4) is effected by movement of a conductor assembly (20) through a guide pipe (11) under fluid pressure acting on a piston (25) at the leading end of the assembly. The fluid can be a dielectric oil and the assembly (20) can be hollow for circulation of the oil for cleaning contacts and for cooling purposes as well as for operating equipment in the undersea installation and for monitoring its performance.
