Abstract
The present invention generally relates to an inline pressure compensator that compensates for volumetric changes within Field-Assembled Cable Termination (FACT) structures when exposed to high pressures and extreme subsea depths by transferring a pressure compensating fluid into the internal cavity of the FACT. The present invention may comprise a flexible internal component and an outer shell-like component. The inner component may comprise two concentric rings of edge-welded bellows that are joined together and wrapped around inner components of the termination or of the inner portion of the outer component. The inner void in the bellows may be filled with pressure-compensating fluid. The pressure compensating fluid diffuses directly into the fluid-filled cavity of the termination assembly. The exterior component may comprise a housing adapted to protect the interior bellows component and provide for seawater to fill the space around the periphery of the bellows arrangement.
