MARINE ICE-STRENGTHENED PLATFORM Russian patent published in 2017 - IPC E02B17/02 B63B35/44 

FIELD: construction.

SUBSTANCE: invention relates to marine mobile platforms. A marine ice-strengthened platform comprises a base plate made with the possibility to adjust its buoyancy, coaxially associated with a support shell on which an upper structure is mounted with the possibility of vertical movement along it. The base plate is equipped with vertical through channels adapted for entering piles and securing them therein. The plant is equipped with a mounting frame movable along the axis of the support shell and equipped with several pile driving means made movable along the mounting frame perimeter. For this purpose, the mounting frame is provided with at least two rail guides spaced vertically. Wherein the protective casings of the pile driving means are made longer than the water area depth at the platform location and are installed in the clamps of the carriages interacting with said rail guides, the carriage clamps being made with the possibility to turn off clamping the casing therein. The casing is mounted with its longitudinal axis preferably coaxially with the axis of the vertical through channels of the base plate. Pile extraction means made in the form of crane plants are arranged on the deck of the upper structure. The pile driving means are made in the form of a vibratory pile hammer and a protective casing with a diameter larger than the diameter of a vertical through channel of the base plate, made with the possibility of coaxial airtight docking with the base plate equipped with water and / or silt removing means.

EFFECT: possibility of operating an ice-strengthened platform in shallow areas of the continental shelf with weak base soils.
