The Oil Sea Drill Platform. The patent.

The copyright certificate: RU 2057845C1 (6 E 02 B 17/00) Gravity base offshore platform - comprises base with ballast tanks, base plate, anchoring piles and swing doors. Priority the invention of 03.29.1993. The range of application of the invention - hydraulic engineering buildings, foundations, foundations, and is particular installation of marine stationary gantries on bottom, mining of a design solution of a gantry. Gravity base offshore platform - comprises base with ballast tanks, base plate, anchoring piles and swing doors. The platform has a base with ballast tanks, base plate (1), anchoring piles (2) and swing doors (4), which is horizontal position are flush with the plate (1). One side of each door (4) is hinged to underside of the plate (1) and the opposite side to rod (8) of the hydraulic jack (9) provided with a hydraulic shock absorber (10) with spring (11). The doors (4) pivot relative the plate (1) up to 90 deg. and are spaced on the line perpendicular the hinges axes at the distance equal 0.15 of their le gth. Moreover, sensors of contact with the base (17) are placed on the doors face edges along their heights at the distance equal 0.1 of the height. The plate (1) has side projections (21) with openings for the piles (2). USE - In offshore drilling. ADVANTAGE - Accurate setting without damage to sea bottom and reliable anchoring of the base plate (1) which has a long service life. The purpose of the invention - heightening of fidelity of downing of a marine stationary gantry on seabed by means of creation of a stationary offshore platform supplying independent regulation of braking of a gantry simultaneous with е ╦ with submergence, sealing and leveling lay also of continental ground, reliable attachment of a gantry to ocean floor by anchor piles, heightening of hardness, cracking resistance both longevity of a bed plate and gantry. Substance of the invention - in creation of a stationary offshore platform and on this base mining of mounting condition of a marine stationary gantry enabling to increase fidelity of installation on seabed by means of independent regulation of the approach of a gantry at the expense of extinguishing of energy by structural members of a gantry. The mounting condition marine permanently gantries includes leveling ocean floor in a place of arranging of a gantry; Simultaneously with submergence of a gantry braking a gantry by rotary desks installed on the back end of a gantry is carried out deflecting them step-by-step on an angle 0-90 to е ╦ to the back end, and at a contact moderate from 90 up to 0 grades; anchoring of a gantry by anchor piles to ocean floor. The marine stationary gantry includes braker desks adnate by edge to the back end and flush-mounted with the back end of a bed plate, the deflection of desks is carried out a hydraulic advancing cylinder, joint with the hydroabsorber, the bed plate has cantilevered lugs with vertical openings, in which one flush with the back end the piles with hydraulic jacks or percussive systems are established. Novelty of the invention in applying rotary desks for braking a gantry at the approach to a place of embedding this oil platform.
