Abstract: A method and system for the offshore production of fuel includes an offshore marine platform on which is mounted an ammonia production unit. The ammonia production unit may produce ammonia utilizing raw materials sourced adjacent the marine platform, including seawater and electricity from offshore wind turbines. The produced ammonia may be subsequently liquified and transported away from the marine platform, or conveyed to a remote location via a seabed pipeline. A portion of the hydrogen produced as part of the ammonia production process may be utilized to operate onboard combustion turbines that can in turn drive electric generators onboard the marine platform to produce electricity.

Abstract: A method and system for the offshore production of fuel includes an offshore marine platform on which is mounted a hydrogen production unit. The hydrogen production unit may produce hydrogen utilizing raw materials sourced adjacent the marine platform, including seawater and electricity from offshore wind turbines. The produced hydrogen may then be blended onboard the marine platform with liquefied natural gas delivered to the marine platform in order to produce a blended fuel comprised of the delivered natural gas and a portion of the produced hydrogen. The blended fuel may be subsequently liquified and transported away from the marine platform, or conveyed to a remote location via a seabed pipeline, or combusted by onboard combustion turbines that can in turn drive electric generators onboard the marine platform to produce electricity.

Abstract: 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.

Abstract: 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.

Abstract: A system for offshore electricity generation and direct carbon dioxide sequestration includes an offshore marine platform on which is mounted a plurality of internal combustion engines. The marine platform is deployed above an offshore, subsea storage reservoir. The internal combustion engines drive electric generators to produce electricity. Flue gas from the internal combustion engines is directed to a carbon dioxide capture system adjacent the internal combustion engines and in fluid communication with the flue gas exhausts of the internal combustion engines. The carbon dioxide capture system captures gaseous carbon dioxide from the flue gas, and then injects the captured carbon dioxide directly into the offshore, subsea storage reservoir. Compressors in fluid communication with the carbon dioxide capture system may be utilized to increase the pressure of the captured gaseous carbon dioxide to a desired injection pressure.

Abstract: 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.

Abstract: Offshore terminal apparatus which in various examples comprises a floating storage vessel which is spread-moored in fixed heading orientation to a seabed offshore by spread mooring lines, the floating storage vessel comprising a hull having bow and stern ends and which at either or both the bow end and the stern end is fitted with an extension section and includes coupling means on the extension section to couple spread mooring lines to the floating storage vessel.

Abstract: Systems and methods provide for offloading liquefied gas, e.g. liquefied natural gas (LNG), from a cargo vessel offshore and regasifying the offloaded gas. In example systems, a floating storage unit is moored to the seabed offshore; first tubing offloads liquefied gas from the cargo vessel to the storage unit; a jack-up platform is positioned offshore in proximity to the floating storage unit, the jack-up platform comprising legs which are arranged to be supported on the seabed and a hull which is arranged to be jacked up along the legs to a position above the sea surface; a regasification facility is provided on the jack-up platform; second tubing extends between the storage unit and the regasification facility of the jack-up platform for transferring liquified gas from the cargo vessel to the regasification facility for regasification of the liquified gas; and third tubing communicates regasified gas away from the regasification facility, e.g. to shore.
