MARINE STATIONARY PLATFORM Russian patent published in 1996 - IPC

FIELD: hydraulic building, in particular, marine dismantling platforms for operation at freezing seas. SUBSTANCE: platform has underwater foundation part 2 and upper structure 3. Projecting male pins 7 are installed on the surface of foundation part. Upper structure 3 is provided with female cylinders 9. Each cylinder has hood 10 connected to the cylinder through easy removable joint in the form of stops 13 enabling to reciprocate from hydropiston system. The pins are placed in the hood with a gap filled with cement slurry. Solidified cement 11 provides stiff monolithic interconnection of the two platform parts. Stops 15 disengage hood 10 to disconnect upper structure 3 from underwater foundation section. This results in floating up the upper structure, and cemented hoods are left in place.
