Abstract: A subsea enclosure arrangement for a subsea component, the enclosure includes walls of a fluid tight material, each wall terminating in a flange; a cover for closing the enclosure; an elastomeric seal between the flange and the cover; compressive members to apply a compressive force to the elastomeric seal, via the cover and the flange; a bracket connecting the flange to the cover; a weld seal between the bracket and the flange; and a weld seal between the bracket and the cover.

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).
