SUPPORT STAND-ANCHOR OF MARINE PLATFORM Russian patent published in 2014 - IPC E02B17/02 

FIELD: construction.

SUBSTANCE: invention relates to construction of platforms to mount drilling and oil production equipment in the sea. The support stand-anchor of the marine platform comprises joined upper section with the upper support site, ballast cisterns-sections and the lower drilling section, in which there is a hydraulic engine installed, to the shaft of the rotor of which a drill is connected, and a pipeline of water drain and a nozzle of water drain are connected to the stator of the hydraulic engine. At the same time on the marine platform in the control cabin the system of filling-emptying of ballast cisterns-sections additionally comprises a compressor for compressed air, the outlet of which via serially connected first valves and three-way switching valves are connected to pipelines of compressed air supply, hydraulic pumps. Between ballast cisterns-sections there are remote support sections, the upper section is made in the form of two coaxial hollow cylinders arranged relative to each other coaxially. The upper support site by means of hinge parts rigidly connected to it and the marine platform, may rotate around the common axis of the hinged joint, and with it the entire support stand of the anchor with removal of the bolt joints by means of its transition from the vertical working position into the horizontal transport position.

EFFECT: expansion of functional capabilities of a support stand-anchor and reduction of axial load.
