DYNAMIC DEVICE FOR COMPENSATION OF LOADS ON SYSTEM OF UNDERWATER COLUMN HEADS Russian patent published in 2021 - IPC E21B33/43 E21B15/02 

FIELD: subsea hydrocarbon production.

SUBSTANCE: invention relates to the field of subsea hydrocarbon production, in particular to a dynamic device for compensating the loads on a system of underwater column heads, including a conductor column and a direction column. A dynamic device is proposed for compensating the loads on the system of underwater column heads, including the conductor column and the direction column, which contains: a caisson; a cover that delimits from above an annular cavity formed by the outer and inner annular walls, and is made integrally with the caisson; underwater blowout preventer (BOP) with position sensors; a removable platform with hydraulic cylinders with a central hole for accommodating a system of underwater column heads; pressure distribution follower capable of receiving signals from position sensors of underwater BOP equipment and supplying pressure to hydraulic cylinders in accordance with signals from position sensors of subsea BOP equipment.

EFFECT: invention increases reliability, durability and safety of operation of the underwater column head system by effectively compensating the loads on the underwater column head system.
