Systems and processes for recovering a condensate from a conduit. In one embodiment, the system can include a floating buoy that can include a fluid swivel assembly coupled thereto. The system can also include a floating conduit, a first gas transfer conduit, and a second gas transfer conduit that can be configured to transfer a gas discharged from a vessel storage tank to a pipeline end manifold located at a subsea location. The system can also include a first condensation conduit, a pump, and a second condensation conduit that can be configured to transfer at least a portion of any condensate that accumulates within an internal volume of the floating conduit at a low point between the vessel storage tank and the first gas transfer conduit into a flow path defined by a first swivel section of the fluid swivel assembly, a storage tank, or a combination thereof.

Systems and processes for transferring a gas from a buoy. In one embodiment, the system can include a buoy floating in water. A fluid swivel assembly can be coupled to the buoy. The system can also include a gas submarine conduit and a pipeline end manifold located at a subsea location. The gas submarine conduit can be configured to transfer a gas between the fluid swivel assembly and the pipeline end manifold. The gas submarine conduit can include one or more negatively buoyant members coupled thereto. The one or more negatively buoyant members coupled to the gas submarine conduit can urge the gas submarine conduit toward a seafloor to maintain the gas submarine conduit in a Chinese lantern configuration.

Systems and processes for recovering a gas from a vessel. The system can include a buoy that can include a fluid swivel assembly. The fluid swivel assembly can have a first swivel section rotatably coupled to a second swivel section. The system can also include a first liquid transfer conduit, a first gas transfer conduit, a second liquid transfer conduit, and a second gas transfer conduit. The first swivel section and the second swivel section can be configured to maintain fluid communication between the first liquid transfer conduit and the second liquid transfer conduit. The first swivel section and the second swivel section can be configured to maintain fluid communication between the first gas transfer conduit and the second gas transfer conduit. The first gas transfer conduit and the second gas transfer conduit can be configured to convey a gas from a vessel to a subsea location.

A buoyant hybrid riser/tension (BHRT) member moors a floating body on the sea surface to a pipeline terminated at a submerged structure. The BHRT includes one or more conduits, one or more tension members, and buoyancy. The conduits provide fluid communication from the pipeline at the submerged structure the tension member absorbs the mooring load and the buoyancy cooperates with the tension member to produce a soft restoring force for mooring the floating body to the submerged structure. The BHRT lower end connection allows angular, but not torsional displacement with respect to the submerged structure. In one arrangement of the BHRT lower end, localized flexing is allowed in the separate conductors via bend stiffeners. At the BHRT upper end, several arrangements for the connection between the BHRT and floating body are provided. In one arrangement, a rigid connection is established between a male coupler at an upper end of the BHRT and a female coupler on the floating body. In a second arrangement, the upper end of the BHRT includes a riser end buoy with a mating surface that connects with a female receptacle mounted on a bearing assembly on the floating body. On top of the female receptacle is an ESD valve block and a swivel (in one arrangement) or a manifold block (in another arrangement). The BHRT can &ldquo;wind up&rdquo; in torsion when the floating body weathervaning. Such wind up can be undone by temporarily releasing a brake which normally secures the female coupling to the floating vessel and allowing the BHRT and female coupling to rotate backward with respect to the floating vessel.
