OFFSHORE PRODUCTION COMPLEX Russian patent published in 2003 - IPC

FIELD: development of subaqueous deposits of minerals, mainly, liquid and gaseous, and construction of production complexes for performance of mainly producing operations on open sea shelfs. SUBSTANCE: offshore production complex has offshore platform, underwater satellites and onshore production base interconnected by production communication lines. Offshore platform includes base rigidly connected with ground by means of piles. Installed on base is horizontal platform with production equipment. Underwater satellites include operating wells with wellhead equipment. Base of offshore platform consists, at least, of two parts. Lower part is rigidly connected with ground, and upper part carries horizontal platform with production equipment. Base is provided with fixing members for successive fixation of relative positions of base lower part, upper part and horizontal platform between one another, and members of quick-break joints of production communication lines. Base upper part is made with ballast vessel. Horizontal platform with production equipment are made with positive buoyancy, and base lower and upper parts are provided with companion guides for provision of their relative shifting. EFFECT: increased economic efficiency and safety of operation due to exclusion of collision of offshore platform with ice cover and icebergs. 3 cl, 3 dwg
