  • Patent number: 8439080
    Abstract: A pressure compensator is configured to compensate for volume variations of an insulation medium or other liquid of a subsea installation. The pressure compensator includes a first bellows chamber having a first bellows part. The first bellows chamber is in flow connection with an insulation medium or liquid chamber of the subsea installation, and the walls of the first bellows chamber are configured to separate the insulating medium from surroundings. The first bellows chamber is surrounded by a second bellows chamber having an end wall, a side wall and a second bellows part formed by a diaphragm. The second bellows chamber is configured to form a closed intermediate space around the first bellows chamber. The walls of the second bellows chamber are configured to separate at least the bellows parts of the first bellows chamber from the surrounding water. The second bellows chamber is filled with an intermediate medium.
