A mooring buoy system releasably connects risers and anchor lines to a turret of a floating structure, and includes: a buoyant body carrying the risers, which extend to a subsea hydrocarbon well; anchor line connectors, for connecting anchor lines to the buoyant body, each anchor line having one end connected to a connector and the opposing end to the seabed; and a reconnection wire running through a channel coinciding with a center line of the buoyant body, connectable to each anchor line below the buoyant body at some distance from the anchor line connectors through anchor line connection sections on one end and includes a stopper and winch wire connection arrangement on the other end. Also disclosed is a method for pulling up risers and anchor lines, for releasably attaching the risers and anchor lines, as well as a method for constructing a mooring buoy.

An apparatus for use with a submerged compartment is presented. The apparatus includes deployable physical connection hardware provided with the submerged compartment. The deployable physical connection allows for a transfer of fluid between the submerged compartment and a region near a marine free surface when deployed. The deployable physical connection hardware comprises a hose in one aspect.

A bearing system including a wheel assembly transmitting load to a damping assembly, wherein the wheel assembly is configured to rotate angularly relative to the damping assembly.

The invention concerns a vessel (1) for storing and/or producing hydrocarbons and a buoyant turret buoy (6) to be connected to the vessel (1). The outer surface of the bow (2) of the vessel (1) comprises a receiving structure (5) for connecting a buoyant turret buoy (6) to the bow (2). The main part of the receiving structure (5) protrudes from the lower part (4) of the bow (2) in the vessel's (1) direction of travel and an interface of the receiving structure (5) is complementary to an interface of a connecting section (17) of the buoyant turret buoy (6). Further the lower part (4) of the bow (2) is below the water line (w) during connection of the buoyant turret buoy (6) at sea. The invention also concerns a method for connecting the buoyant turret buoy (6) to receiving structure (5) of the vessel (1).

Systems and processes for recovering condensate from a conduit. The system can include a buoy that can include a fluid swivel assembly. The system can also include a first surface conduit and first and second gas transfer conduits that can be in fluid communication with the fluid swivel assembly and configured to transfer a gas discharged from a vessel storage tank to a gas pipeline. The system can also include first and second liquid transfer conduits in fluid communication with the fluid swivel assembly and configured to transfer a liquid from a liquid pipeline to the vessel storage tank. The system can also include a condensation conduit configured to transfer at least a portion of any condensate that accumulates within an internal volume of the first surface conduit or the first gas conduit into a fluid flow path defined by the fluid swivel assembly or the second liquid transfer conduit.

A turret mooring and riser hang-off arrangement, for transferring petroleum products from an off-shore or subsea facility to a vessel, including a turret arranged in a cavity of the vessel. The turret is held firmly in axial and radial directions within the cavity, but is rotatable relative to the vessel. The turret is adapted to be moored to the seabed. A riser assembly extends through a bore in the turret to an upper surface of the vessel. The bore of the turret is a monobore and the riser assembly is rotationally coupled to the turret but is free to move axially relative to the turret. The riser assembly is axially supported by the vessel.

A Taut-Inverted-Catenary (TIC) mooring system may be implemented using only field-proven components. The mooring lines yield a positive uplift force on the anchors in all conditions. In the inverted-catenary configuration, geometric stiffness is provided by a subsurface spring buoy or distributed buoyancy elements on the line. The TIC system consists as much as possible of light-weight components, such as polyester fiber rope. Since the uplift force on the anchor is always positive, clearance between polyester rope and the seabed is provided. All geometric stiffness is provided by the spring buoy. Therefore, a ground chain between the seafloor anchor and the fiber rope is not necessary.

A mooring assembly includes: a mooring buoy having a central axis, an upper ring portion providing an upper abutment surface; a mooring structure including a cavity with a wall receiving the mooring buoy; and a buoy locking system near the cavity engaging with the upper ring portion for locking the mooring buoy to the turret mooring structure and including at least two locking devices attached to the mooring structure, each locking device having a locking dog connected to a force member for axial displacement and exerting an upward force on the upper abutment surface. The mooring buoy includes a lower abutment surface. The locking system includes an engagement member below the locking dog, engaging with the lower abutment surface and exerting a downward force. The buoy at positions axially above the upper abutment surface situated at an axial clearance from the cavity wall.
