Abstract:
A method for suspending a pipeline in the sea between a hydrocarbon facility positioned above a sea bed and a CALM buoy comprising,providing a buoyant body at the sea surface in proximity to a desired location of said CALM buoy, providing one or more buoyancy members on said pipeline so that said pipeline is substantially at the sea surface with an outlet end adjacent said buoyant body, connecting a flexible tension member between said buoyant body and a gooseneck connection member with said outlet end of said pipeline fluidly coupled to an inlet end of said gooseneck connection member, connecting an inlet end of said pipeline to said hydrocarbon facility, adjusting said one or more buoyancy members, lowering said buoyant body to a desired submerged position, and mooring said buoyant body to said sea bed, so that said pipeline is submerged in the sea and suspended between said hydrocarbon facility and said buoyant body, mooring said CALM buoy at said desired location, fluidly connecting an inlet end of a marine hose to an outlet end of said gooseneck connection member so that said pipeline and said marine hose are fluidly coupled, and mechanically and fluidly coupling an outlet end of said marine hose to an inlet end of a product swivel mounted on said CALM buoy.
