METHOD OF CONSTRUCTING AN ICE-RESISTANT DRILLING PLATFORM ON THE SHALLOW SHELF OF THE ARCTIC SEAS Russian patent published in 2020 - IPC E02B17/00 

FIELD: drilling platforms.

SUBSTANCE: invention relates to sea ice-resistant platforms for prospecting and exploration well drilling in shallow shelf of Arctic seas, specifically to construction of ice reinforced ice offshore platforms from ice cover, made in form of solid ice reinforced structure resting on sea bottom, and protruding bearing supports, on which the upper part of the platform for arrangement of process equipment is installed. Method of construction of ice-resistant drilling platform on shallow shelf of Arctic seas includes erection of multi-support base and bearing spatial rod supports from drilling casing installed in wells, and erection of platform modular structure, flooring for arrangement of process drilling equipment. In the platform, process holes are made for access to open upper ends of drilling casing pipes, in which coolant with negative temperature is placed, surrounding sea water is frozen to form solid ice reinforced structure, which rests on sea bottom.

EFFECT: technical result is the construction of ice-resistant drilling platform from ice cover on shallow shelf with high resistance to lateral pressure in conditions of movable ice.
