FIELD: construction.SUBSTANCE: underwater structure (US) operates at depth in the range from 100 to 120 m from sea level. At the same time the US comprises a support-bearing underwater complex and a drilling complex or a production complex. The support-bearing underwater complex includes a support-bearing plate and a wellhead complex. The support-bearing plate, in its turn, comprises a wellhead block, an energy block, a residential block, and also a life support block, internal and external circular corridors, radial transitions, sectioned ballast pontoons of circular shape and propelling agents. Retention of the underwater structure in the vertical position at the specified point for the whole period of stay is provided by control of filling of ballast pontoon sections, at the same time retention in the horizontal plane is done due to operation of the propelling agents. The inner surface of the body of the drilling complex and the production complex is congruent to the external surface of the wellhead complex, and the lower surface of the body of the drilling complex and the production complex is congruent to the upper surface of the support-bearing plate.EFFECT: increased safety, reliability and quality of performed works.13 cl, 5 dwg |
