Abstract
A riser assembly and method of supporting a riser assembly are disclosed. The riser assembly includes a riser; at least one buoyancy compensating element attached to the riser; and at least one damped biasing element for controlling movement of the riser about a neutral position with respect to an adjacent underwater structure. The biasing element is directly or indirectly connected to the riser and is directly or indirectly connectable to the adjacent underwater structure.
Claims39
A riser assembly for transporting fluids from a subsea location comprising:
- a riser;
- at least one buoyancy compensating element attached to the riser;
- and
- at least one damped biasing element for controlling movement of the riser about a neutral position with respect to an adjacent underwater structure;
- wherein the biasing element is directly or indirectly connected to the riser and is directly or indirectly connectable to the adjacent underwater structure.
An assembly comprising a first riser assembly for transporting fluids from a subsea location and an adjacent underwater structure, the riser assembly comprising:
- a riser;
- at least one buoyancy compensating element attached to the riser;
- and
- at least one damped biasing element for controlling movement of the riser about a neutral position with respect to an adjacent underwater structure;
- wherein the biasing element is directly or indirectly connected to the riser and is directly or indirectly connected to the adjacent underwater structure.
A method of supporting a riser assembly for transporting fluids from a subsea location, the method comprising:
- providing a riser;
- connecting at least one buoyancy compensating element to the riser;
- and
- providing at least one damped biasing element for controlling movement of the riser about a neutral position with respect to an adjacent underwater structure;
- connecting the biasing element directly or indirectly to the riser and the adjacent underwater structure.
A method of restricting the extent of relative movement of adjacently arranged riser assemblies, the method comprising damping the movement of said riser assemblies with a damped biasing element extending between the respective assemblies and connected directly or indirectly thereto.
