MARINE COMPLEX FOR IN-SITU HYDROCARBON FUEL PRODUCTION OF OIL AND GAS CONDENSATE (VARIANTS) Russian patent published in 2007 - IPC E02B17/00 

FIELD: artificial islands mounted on piles or like supports, particularly adapted for hydrocarbon fuel production of oil and gas condensate, for off-shore territories supply with hydrocarbon fuel and for shit fueling and tank loading with fuel.

SUBSTANCE: marine complex in accordance with the first embodiment comprises bearer made as self-lifting offshore drilling platform having columns fixed on non-prepared marine bottom so that distance between sea surface and pontoon may be changed. In working position the platform is located over water and is supported by the columns. Complex also has loading system installed on pontoon deck and at least two manifolds to receive raw material and to deliver ready hydrocarbon fuel. Initial raw hydrocarbon material cleaning and dehydration plants are arranged in closed rooms on pontoon deck. Complex made in accordance with the second embodiment comprises underwater pontoon and bearer made as self-lifting offshore drilling platform having support columns and pontoon-type body. In working position the pontoon is located over water and is supported by the columns. The support columns are installed on underwater pontoon. The underwater pontoon has shaft communicated with offshore drilling platform pontoon to provide access to underwater one and comprises weight system provided with raw material and ready hydrocarbon fuel manifolds, as well as with raw material and ready fuel tanks. The complex also has local control station communicated with automated above-water pontoon control station.

EFFECT: increased efficiency of hydrocarbon fuel production, improved reliability, decreased costs for complex establishment and erection.
