MARINE ICE-RESISTANT PLATFORM Russian patent published in 2017 - IPC E02B17/00 E02B17/02 

FIELD: construction.

SUBSTANCE: marine ice-resistant platform comprises a base plate 1 made with the possibility to adjust its buoyancy, coaxially interfaced with a support shell 2, on which an upper structure 3 is mounted with the possibility of vertical movement along it. The base plate 1 is equipped with vertical through channels adapted for entering piles and securing them therein. The plant is equipped with several means of piling, made with the possibility to move around the perimeter of the upper structure, for which purpose the latter is equipped with at least two rail guides spaced apart vertically. Protective casings 4 of the piling means are made with a length more than the water area depth at the platform location and are installed in clamps of carriages interacting with said rail guides. The clamps of the carriages are made with the possibility to switch off the locking of the casing 4 therein, and the casing 4 is preferably mounted coaxially with its longitudinal axis with the axis of the vertical through channels of the base plate. Pile extraction means made in the form of crane plants are located on the deck of the upper structure 3, are made in the form of a vibratory pile driver and a protective casing 4, of a diameter larger than the diameter of the vertical through channel of the base plate, made with the possibility of coaxial airtight docking with the base plate equipped with water and/or slit removing means. In addition, each protective casing 4 is equipped with a vertical channel made as a chute projecting from the casing section, provided with a flight of stairs.

EFFECT: possibility of efficient operation of an ice-resistant platform in shallow areas of the continental shelf with weak foundation soils, while increased platform mobility is ensured, because it is adapted to transport in the assembly and installation, high ice-resistance of the platform due to the use of pile fastening of the base, high mounting and dismantling speed of the pile foundation in case of platform relocation to another site.
