Abstract
A support for a subsea riser decouples the function of the riser into two separate functions: the load transfer function which supports the hung weight of a subsea riser configuration to a supporting floater (such as the buoy of a disconnectable fluid transfer system) and the fluid transfer function which provides a continuous flow path for the fluid coming to or from the riser.
Claims17
A riser support comprising:
- a buoy;
- a first articulation connected to the buoy wherein said first articulation is selected from the group consisting of uni-joints, elastomeric joints and gimbal tables;
- a non-fluid-carrying, load-carrying member having a first end connected to the buoy via the first articulation and an opposing second end;
- a second articulation connected to the second end of the load-carrying member and having means for attachment to a riser;
- and,
- a flexible conduit connected at a first end to the buoy and having an opposing second end with means for fluid connection to a subsea riser attached to the second articulation.
