Storage of fluids underwater

A subsea fluid storage system comprises: a seabed foundation 16; a tensile member 14 such as a pipe or a wire extending upwardly from the foundation; and a subsea buoy 12 applying buoyant upthrust to support the tensile member in an upright orientation. At least one fluid storage container 20 is dis...

More Information
Summary:A subsea fluid storage system comprises: a seabed foundation 16; a tensile member 14 such as a pipe or a wire extending upwardly from the foundation; and a subsea buoy 12 applying buoyant upthrust to support the tensile member in an upright orientation. At least one fluid storage container 20 is disposed between the foundation and the buoy. The or each container may be disposed around the tensile member, for example with the tensile member extending through the container. The container has at least one inlet 22 or outlet 24 for fluid communication with a source or a consumer of fluid to be stored in the container. The tensile member may be a riser and the container may be coupled to a flexible hose that extends to the surface. Also disclosed is a method of storing fluid underwater.
