When heat is applied to one end of the heat pipe, the highly volatile liquid in the wick evaporates and the gas ? lls the heat pipe hollow center. This diffuses throughout its length where the external portion of the heat sink pipe or radiator, releases heat into the ambient water. Condensation takes place at the point of heat transfer and capillary action within the wick returns the condensate to the evaporator (heat source) and completes the operating cycle.

The PREVCO dual pipe design has a Copper Beryllium radia- tor exposed to sea water with approximately a ~250W capacity.

The heat sink pipe method has proven to be effective, with a better energy-to-weight ratio and more cost effective.

Subsea7 reports a major advance in its pioneering remote piloting technology offering by fully operating a workclass

ROV from Scotland to carry out operations 9,400km away off the coast of Brazil. The success of the project has proven
