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.
Claims15
A subsea enclosure arrangement for a subsea component, the subsea enclosure comprising:
- walls of a fluid tight material, each wall terminating in a flange extended over both outer and inner sides of the wall in a horizontal direction;
- a cover for closing the subsea enclosure along the inner sides of the flange;
- an elastomeric seal between the flange and the cover along the inner sides of the flange to fluid tight the subsea enclosure;
- 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, the bracket extending in a vertical direction along the associated wall and further bending in a horizontal direction to cover the elastomeric seal, the compressive members, and the cover;
- a weld seal between the bracket and the flange;
- and a weld seal between the bracket and the cover;
- wherein the elastomeric seal comprises an O-ring seal;
- and adapted to receive the subsea component comprising at least one of a transformer, a variable speed drive, a pump, or a compressor.
A method of installing a subsea component in a subsea enclosure arrangement for a subsea component, the method comprising:
- installing one or more components comprising at least one of a transformer, a variable speed drive, a pump, or a compressor through an opening in the subsea enclosure comprising walls of a fluid tight material;
- fitting an elastomeric seal to an inner side of a flange of the walls of the subsea enclosure to enclose the opening;
- fitting a cover over the elastomeric seal to close the opening;
- applying a compressive force to the seal by tightening compressive members in the cover and flange;
- fitting a vertical side of a bracket along the walls and a horizontal side of the bracket to cover over the compressive members, elastomeric seal, and the cover;
- and welding the horizontal side of the bracket to the cover and the vertical side of the bracket to the flange.
