Subsea control and power enclosure

Abstract

An enclosure (10) for a subsea control and power arrangement (12), the enclosure (10) comprises: a cannister (14) and a lid (16), a connector assembly (20), a first volume compensator (22) and a second volume compensator (30). The cannister (14) and the lid (16) form an enclosure volume (18). The first volume compensator (22) having a first chamber (23), the first volume compensator (22) is mounted to the enclosure (10) outside the enclosure volume (18). The first chamber (23) has a variable volume. The second volume compensator (30) having a second chamber (31). The second chamber (31) has a variable volume. The connector assembly (20) extends through the lid (16) and into the enclosure volume (18) and comprises a housing (24) forming a third chamber (26) and a connector part (28). The connector part (28) is mounted at least partly within the housing (24) and the housing (24) is located at least partly within the enclosure volume (18), the connector part (28) extends through the housing (24) and into the enclosure volume (18). The first chamber (23), the second chamber (31) and the third chamber (26) are liquidly connected to one another to form a compensator volume (23, 31, 26). The compensator volume (23, 31, 26) is arranged, in liquid flow order, between the enclosure volume (18) and ambient (54) the enclosure (10) thereby forming at least two sealing barriers between ambient (54) and the enclosure volume (18).
