Abstract
A single point mooring for an offshore body of water, being capable of holding a tanker during a loading or off-loading period. A conduit depending downwardly from the floating mooring to the ocean floor carries fluid from a source thereof. A resilient, shock absorbing member depending from the conduit by a plurality of buoyant connectors, takes up possible strain when the buoy is subjected to excessive lateral displacement due to wind, tide, or other phenomena.
Claims2
In a single point mooring system for an offshore body of water wherein a buoy having a detachable coupling means floats at the water's surface, a resilient, elongated fluid carrying conduit extends dowwardly from said buoy and communicates with a subsea terminal fixedly disposed at the ocean floor, said elongated conduit being communicated with a remote source of fluid, a plurality of hold down cables spaced about said buoy having one end thereof connected to the buoy, and having the other end spaced from said subsea terminal and anchored at the ocean floor,
- a nonrigid restraining member extending between, and having opposed ends thereof connected to said buoy and to said subsea terminal, respectively and being shorter in length than said elongated fluid carrying conduit, and
- at least one buoyant member positioned on said elongated conduit having means thereon to support said conduit above the ocean floor,
- said buoyant member being fixedly connected to said at least one elongated conduit, and being slidably connected to said restraining member whereby to permit limited relative movement between said buoyant member and said restraining member.
