Abstract
A slide-in structural interface between a Sea Water Intake Riser (SWIR) and a floating unit hull or sump tank bottom plate permits a pull-in, diver-less installation of the SWIR. Certain embodiments include an integrated, easily maintainable strainer.
Claims17
A structural interface between a Seawater Intake Riser (SWIR) and a hull or a sump tank bottom plate of a floating vessel, the structural interface comprising:
- a plurality of elements comprising
- a sealing device located at a penetration in the vessel hull or the sump tank bottom plate, the sealing device comprising a male portion and female portion, the female portion being connected to the vessel hull or the sump tank bottom plate;
- a main cylindrical body having a perforated lower portion that is located above the sealing device, the male portion of the sealing device being connected to the main cylindrical body;
- a cylindrical strainer that is coaxial with and inserted into the main cylindrical body;
- a first annular seal located below a perforated section of the cylindrical strainer in an annulus between the main cylindrical body and the cylindrical strainer;
- a second annular seal located above the perforated section of the cylindrical strainer in the annulus between the main body and the cylindrical strainer;
- at least one ring seal located between the male and female portions and configured to provide a watertight seal between the male portion and the female portion;
- and
- a hang-off device located at a penetration through a first horizontal hull-supporting structure that is located above a lower draft of the vessel, the hang-off device comprising a male part connected to the main body, a female part connected to the first horizontal hull-supporting structure, and a split clamp configured to lock the male part vertically in place with respect to the female part;
- wherein the elements are sized and configured to permit the SWIR to be pulled into the penetration with the vessel hull or the sump tank bottom plate from below the hull or sump tank bottom plate and into engagement with the female part of the hang off device.

A structural interface between a Seawater Intake Riser (SWIR) and a hull or a sump tank bottom plate of a floating vessel, the structural interface comprising:
- a radial load transferring device comprising
- a first substantially conical surface attached to the hull or the sump tank bottom plate of the floating vessel, and
- a second substantially conical surface;
- an interface pipe perforated in a lower portion located above the radial load transferring device, the interface pipe comprising a radially extending portion, the second substantially conical surface of the radial load transferring device being on the radially extending portion of the interface pipe;
- and
- a hang-off device located at a penetration through a first horizontal hull-supporting structure that is located above a lower draft of the vessel, the hang-off device comprising:
- a male part, a female part, and a split clamp configured to lock the male part vertically in place with respect to the female part,
- wherein the radial load transferring device, the interface pipe, and the hang-off device are sized and configured to permit the SWIR to be pulled into the vessel hull or the sump tank bottom plate from below the hull or the sump tank bottom plate and through the radial load transferring device.
