A tubular line is connectable between the cargo connection point and the cargo manifold. The method can include attaching a self-propelled buoy to the second vessel; connecting a cargo connection between the self-propelled buoy and the cargo manifold; connecting a cargo line between the cargo connection point and the self-propelled buoy; transferring cargo between the cargo connection point and the cargo vessel; and relying on the self-propelled buoy to keep the self-propelled buoy within predetermined distance boundaries from the first vessel also when the self-propelled buoy is attached to the second vessel.

The first connector part can include a gimbal table, first and second trunnions disposed on the gimbal table, a first arm, and a stopper assembly. The second connector part can include a second arm. The second arm can include one or more shoulders disposed between a first end and a second end of the second arm. The second arm can be configured to be at least partially disposed within an aperture defined by the first arm such that one of the one or more shoulders can engage with the stopper assembly.

A transfer system for transferring a medium between a first facility and a second facility includes a first pipe spool; a compensator; a second pipe spool; a coupling assembly; a transfer skid; and one or more pipe supports. A first end of the first pipe spool is connectable to a manifold provided on a first deck of the first facility and a second end of the first pipe spool is connected to a first end of a compensator. A first end of the second pipe spool is connected to a second end of the compensator and a second end of the second pipe spool is connectable to a first end of a transfer pipe through the coupling assembly. The compensator is configured to allow a relative motion between the first pipe spool and the second pipe spool. The transfer pipe is fluidly connectable with the second facility. The transfer skid comprises an inboard assembly and an outboard assembly. The inboard assembly is mountable to a second deck of the first facility by one or more mounts. The outboard assembly includes a structural frame and one or more pipe supports. The structural frame includes an inner cross-sectional area configured to allow passage of one or more of the second pipe spool, the coupling assembly, and the transfer pipe. The one or more pipe supports support the second pipe spool, the coupling assembly, the transfer pipe, or a combination thereof passing through the inner cross-sectional area of the transfer skid.

Offloading cargo from a cargo vessel and delivering the cargo to a cargo recipient, or loading cargo onto the cargo vessel from a cargo supplier, may be performed using a cargo vessel which is spread moored at sea to a plurality of mooring points for mooring the cargo vessel in a desired orientation. Alternatively, the cargo vessel may be rotatably moored. Tubing may be provided and configured to be connected to the vessel for fluid communication between the vessel and the cargo recipient or the cargo supplier, and may comprise a first portion configured to be connected to the cargo vessel and a second portion configured to be connected to the cargo recipient or the cargo supplier. A semi-submersible unit may be operable to travel across the sea and carry part of the tubing from a stand-by location to a position adjacent to the cargo vessel, so as to allow an end of the first portion of the tubing to be connected the cargo vessel for offloading or loading the cargo. The unit may have at least one lifting and handling device, which when the unit is positioned adjacent to the cargo vessel, may be operable for arranging the end of the first portion of the tubing at or near a manifold on the cargo vessel for connection thereto.

A system and method are for transferring fluid cargo between a cargo vessel and a cargo connection point at open sea where the cargo vessel is required to keep an end portion of the cargo vessel up towards the resultant element force direction, wherein at least one self-propelled buoy, that is designed to be in fluid connection with the cargo connection point, is connectable to a side portion of the cargo vessel, there being a cargo line that is connectable between the self-propelled buoy and the cargo vessel, and where the self-propelled buoy is designed to keep the self-propelled buoy within predetermined radial distance boundaries from the cargo connection point also when it is attached to the cargo vessel.

An offshore loading system operable to load a substance between a first structure and a second structure separate from the first structure, the second structure including a manifold, includes a loading arm having a process pipe to carry the substance during a process of loading the substance by the loading arm, the process pipe including a free end, the loading arm coupled to the first structure. A control unit is coupled to the loading arm and operable to direct the free end of the loading arm, and a first acceleration sensor electronically coupled to the control unit. The first acceleration sensor is operable to detect relative movement of the first structure with respect to the second structure.

A high pressure swivel system provides fluid communication on a turret-moored vessel between a swivel core member being in fixed rotational alignment with a seabed mooring system and a swivel revolving member being in fixed rotational alignment with the hull of the vessel. The revolving member has upper and lower radially extending surfaces. On each of the radially extending surfaces are a series of radially spaced apart pressure seals. Hydraulic barrier fluid pressure is regulated in each of the volumes formed between the pressure seals. The pressures in the volumes are regulated such that a process fluid pressure higher than could be tolerated by any one individual pressure seal is safely accommodated by sharing the high process fluid pressure between or among two or more of the radially spaced apart pressure seals.

A modular floating platform system includes a detachable floating buoy providing a body tethered to a seafloor with a plurality of mooring lines and coupled to a subsea production system via one or more communication lines, and a plurality of floating surface facilities, each floating surface facility providing a standardized bottom interface matable with the detachable floating buoy. A latching mechanism individually couples each floating surface facility to the detachable floating buoy when each floating surface facility is individually mated to the detachable floating buoy. One or more communication couplings place each floating surface facility in communication with the subsea production system via the one or more communication lines when each floating surface facility is individually mated to the detachable floating buoy.

A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.
