METHOD FOR INSTALLATION OF HYDROTECHNICAL STRUCTURE SUPPORT UNIT ONTO SEA BOTTOM Russian patent published in 2009 - IPC E02B17/00 

FIELD: construction.

SUBSTANCE: method for installation of support unit (1) onto sea bottom, in which support unit (1) is transported on transport barge (2) to the place of its installation, with the help of lifting devices (3), which are symmetrically installed in pontoons (4) on both sides of transport barge (2), taken off transport barge (2), and support unit (1) is lowered to sea bottom in vertical position, differs by the fact that pontoons (4) are rigidly connected to each other by means of cross beams (5) with device (6) for regulation of distance between pontoons (4), at the same time lifting devices (3) are made in the form of stands (7) with hydraulic jacks installed on them (8), base of stands (7) is rigidly installed on pontoons (4), and upper parts of stands (7) are connected to structure of support unit (1) through system of hydraulic jacks (8).

EFFECT: reduced labour intensity, costs and risk level in production of works for installation of support unit of stationary platform onto sea bottom due to application of method for installation of support unit onto sea bottom with the help of floating technical means-pontoons equipped with special weight-lifting systems.
