FIELD: hydraulic engineering, particularly underwater structures adapted for oil and gas well operation, preferably on shallow continental shelf having bottom covered with thick silt layer and in ice-covered period. ^ SUBSTANCE: platform comprises base, vertical pile holders connected with the base and positioning unit for drilling string and well-control equipment fixation. Base is formed as a structure with cavities filled with ballast. The structure is composed of hollow members and functionally divided into two areas. Positioning unit is arranged in the first area, another area including catching opening. Platform is additionally provided with removable mounting frame with production equipment installed on the frame. Arranged in lower frame part are inclined guiding means to provide access into catching opening during mounting frame connection with support platform base in underwater position. ^ EFFECT: reduced labor inputs for production equipment mounting and maintenance, increased reliability. ^ 7 dwg |
