Zusammenfassung:Some previously proposed subsea installations have lower pressure compensator lifetime and are less reliable. Disclosed here in is a subsea installation that (2) comprises a tank (3) containing an insulation fluid (4) or other fluid, a heat generating electric apparatus (7) positioned at least partly within the tank, and a pressure compensator (1) 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 (5) the insulation fluid or the other fluid, said means for heating being configured to provide heating to the insulation fluid or the other fluid when 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.
