摘要

FIELD: stationary sea oil platforms.;SUBSTANCE: block has underwater support, made in form of two-level bench, formed by vertical beam cases and horizontal links, and also has support columns, connected to support. Horizontal links of bench are made in form of floating tanks, while links, placed along perimeter of lower level of bench, are separated by water-impenetrable walls on sections, provided with ballasting means. Method for mounting support block at the bottom of continental shelf includes transporting, ballasting of floating tanks and fixing support block at the bottom of water body. Support block is transported into wells drilling zone in planned position, sections of floating tanks are ballasted until lower level of support lowers into bottom of water body for 0.3-0.7 of its height, different and slants are evened and holding beams are inserted into cases of support with their following forcing into hard bottom portion and fixing in cases. Ballasting of sections of floating tanks and forcing of holding beams can be performed in pairs in diagonal planes relatively to center of lower level of support.;EFFECT: simplified assemblage, higher reliability.;2 cl, 12 dwg
