ABSTRACT:
The platform comprises an annular truncated cone of concrete which constitutes the main resistant element of the platform and is designed to take the thrust of ice, and a cylindrical steel part housed inside the annular truncated cone. Watertight passages parallel to the generatrices of the cylindrical wall are provided to house piles in the peripheral ring, close to the wall. A watertight passage well is provided in the cylindrical steel part for the passage of the drill pipes. A circular running track is provided for gantry cranes used for piles handling. The platform has two drilling rigs placed on one half of the platform and able to work simultaneously.
