Partial discharge measurements have been used for studying shrinkage voids in the insulation of mass-impregnated high voltage DC subsea power cables. Three 4.5-m long cable samples were subjected to ac partial discharge measurements at different ambient temperatures, both under isothermal conditi...

The total recovery of natural gas from subsea wells can be significantly increased with a compressor installed near the wellheads. The compressor is powered by a high-speed induction motor integrated in the same casing. The process gas flows through the motor and acts as a cooling medium. The insula...

Subsea installations on the sea bed at great depth require insulation materials with high reliability. Failures of such installations introduce difficult maintenance and high costs. This involves the need of reliable (insulation) materials and testing of such. The purpose of our activity is to build...
