Abstract
A riser system with a primary conduit extends between a surface vessel and a subsea location and an auxiliary conduit that extends adjacent the primary conduit. In one example a composite jumper conduit extends from the surface vessel and is fluidly connected to the auxiliary conduit. The jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix. In one example a subsea composite jumper conduit extends from subsea infrastructure and is fluidly connected to the auxiliary conduit. The subsea jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix.
Claims31
A riser system, comprising:
- a primary conduit extending between a surface vessel and a subsea location;
- an auxiliary conduit extending adjacent the primary conduit;
- and
- a composite jumper conduit extending from the surface vessel and being fluidly connected to the auxiliary conduit, said jumper conduit comprising a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix, wherein the jumper conduit is located entirely above the auxiliary conduit, wherein the jumper conduit extends in a curved profile without defining any inflection point, wherein the jumper conduit is mounted on a reel located on the vessel and wherein the reel is operable to rotate to selectively pay-in and pay-out the jumper conduit therefrom to accommodate relative movement between the vessel and the auxiliary and/or primary conduits.
A method for deploying a riser system, comprising:
- deploying a primary conduit from a surface vessel to a subsea location;
- deploying an auxiliary conduit to extend adjacent the primary conduit;
- and
- extending a composite jumper from the surface vessel, wherein the composite jumper is fluidly connected to the auxiliary conduit, said jumper conduit comprising a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix wherein the jumper conduit is deployed to be entirely above the auxiliary conduit and to extend in a curved profile without defining any inflection point,
- mounting the jumper conduit on a reel located on the vessel, the reel being operable to rotate to selectively pay-in and pay-out the jumper conduit therefrom to accommodate relative movement between the vessel and the auxiliary and/or primary conduits.
