A subsea fluids storage facility comprises a tank (11) for holding and separating fluids which is equipped with ballast capacity (14) and a separable base (12) to be deployed upon the seabed in shallow or deep water, and the storage facility is connectable to a surface production facility, especially a buoy (24) for processing fluids. In deep water the tank (11) is held at a depth above the base (12) for temperature controlled stabilization of produced oil in the tank (11).

A floating type LNG station floats on the sea and is used for refueling a ship or a marine structure using LNG. The floating LNG station comprises: a floating structure; an LNG tank which is prepared for storing LNG in the floating structure; an LNG line for discharging the LNG from the LNG tank to the ship or the marine structure; and an LNG pump which provides the LNG line with pumping force for discharging the LNG.

An offshore LNG processing plant includes a first module including a personnel accommodation facility on a first vessel, a second module including a gas treatment facility on a second vessel, and a third module including a gas liquefaction facility on a third vessel. Each of the first, second, and third modules are assembled on the corresponding vessels, and then transported to an offshore location in a body of water, such as a river, a lake, or a sea. At the offshore location, each vessel deploys legs to the bed of the body of water to raise a hull of each vessel out of the water. The first module is then coupled to the second module, and the second module is coupled to the third module. A fourth module on a fourth vessel is coupled to the third module to provide LNG storage.

A fluid cargo handling system with a standoff system includes a floating marine platform having an elongated first platform side, an elongated second platform side and a buoyant hull with a hull bottom. A fluid cargo transfer hose is carried on a hose reel mounted on the platform. A drive system maintains the marine platform at an offset distance from another marine platform, preventing physical contact therebetween. The drive system has at least two drive devices adjacent the first platform side and at least two drive devices adjacent the second platform side, with each of the drive devices along the first side engaging a separate driveline extending from the hull bottom adjacent the first side towards the second platform side and each of the drive devices along the second side engaging a separate driveline extending from the hull bottom adjacent the second side towards the first platform side.

A fluid cargo handling system includes a marine manifold tower system and a floating marine platform on which is carried a liquid manifold assembly which is coupled to a cryogenic liquid transfer hose extending from the floating marine platform to the marine manifold tower system. The cryogenic liquid transfer hose is also connected to a cryogenic hose manifold assembly mounted on the marine manifold tower system. The marine manifold tower system includes an elongated tower having a first end secured to the seabed and a second end supporting the cryogenic hose manifold assembly, elevating the cryogenic hose manifold assembly above the water surface. The floating marine platform moves between a first position adjacent the marine manifold tower system and a second position, spaced apart from the marine manifold tower system, where the floating marine platform is in fluid communication with a fluid cargo transport vessel.

A fluid cargo handling system includes a quick release manifold system mounted on a floating marine platform. The quick release manifold system has a first valve in fluid communication with the first end of a first fluid transfer hose to control fluid flow within the first fluid transfer hose. A first coupler is attached to the first valve. The first coupler has a first port in fluid communication with the first valve, a second port, a purging fluid inlet and a waste fluid outlet. A drain tank is in fluid communication with the first coupler via the waste fluid outlet, and a pressurized fluid source carried is in fluid communication with the first coupler via the purging fluid inlet.

A bunkering marine vessel has an elongated, multi-deck accommodation structure extending along a portion of the length of one hull side and spaced apart from a centerline extending from bow to stern. Positioned within the vessel hull is at least one LNG pressure vessel filling at least 50% of the hull volume and extending from adjacent a lowermost deck to adjacent the main deck. At least one marine gasoil tank is positioned along an opposing hull side to counter the weight of the accommodation structure, The bow and stern ends of the vessel are substantially the same in shape, and each end includes a marine propulsion system.

Systems and methods are described for sequestering carbon stored in organic matter while minimizing the release of carbon dioxide (CO.sub.2) and methane (CH.sub.4) into the atmosphere, with the carbon (C) being stored as char or coal through the coalification process. Organic matter will be moved to submarine hydrothermal vent fields where the extreme heat in the water will drastically accelerate the degradation of the material and destroy microbes that normally consume the organic material and release the carbon as CO.sub.2 or CH.sub.4. The oxygen level in the heated water around the vents is extremely low. The water surrounding these vents can reach temperatures of 400° C. (750° F.). Exemplary implementations may include constructing hydrothermal borehole vents to harness the energy continuously released from the Earth's core in the form of volcanic heat.
