SEMISUBMERSIBLE CATAMARAN-TYPE DRILLING PLATFORM

摘要

FIELD: oil-and-gas industry.SUBSTANCE: invention relates to deep water drilling oil and gas platform designed for operation at arctic shelf. Semi-submersible catamaran-type drilling platform is arranged at two pontoons, platform hull being supported by stabiliser columns and tensioned vertical mooring, with computer-aided dynamic positioning with the help of underwater propulsors. Surface deck superstructures are composed of drilling, processing, power production and functional modules. Integrated control and safety systems are equipped with production equipment conditions monitoring means and emergency elimination means to actuate by remote means at well fluid flowing the device of static electricity charges elimination at drilling platform.EFFECT: higher survivability of drilling platform at well fluid flowing.5 cl
