Abstract: A method for estimating the remaining useful life of a pressure compensator of a subsea arrangement, the method including determining displacement data related to displacements of the pressure compensator during a time period; and estimating the remaining useful life of the pressure compensator in relation to a failure mode of the pressure compensator based on the determined displacement data of the pressure compensator. A system including a subsea arrangement and a control system, a computer program product, and a computer program, are also provided.

Abstract: A subsea installation. The subsea installation comprises a tank containing an insulation fluid or other fluid, a heat generating electric apparatus positioned at least partly within the tanks, and a pressure compensator being in fluid communication with the tank and being configured to compensate volume variations of the insulation fluid or the other fluid by performing an expansive and a contracting movement. The subsea installation comprises further means for heating the insulation fluid or the other fluid, said means for heating being configured to provide heating to the insulation fluid or the other fluid with the heat generating electric apparatus is in a non-operating state in order to reduce the volume variations of the insulation fluid or the other fluid.
