BALANCED MARINE HELIPAD Russian patent published in 2023 - IPC B63B35/50 B64F1/00 

FIELD: shipbuilding.

SUBSTANCE: invention is related to helicopter landing pads for offshore engineering structures. The invention can be used at offshore facilities of the oil and gas industry, as well as on medium and large-capacity vessels of a technical fleet. The objective of the invention is to ensure the landing of a helicopter on the helipad both during the operation of a marine engineering structure, and in the event of a possible emergency roll of a marine engineering structure in any direction for a rescue operation, delivery of rescuers, helicopter support for emergency and repair work. A balanced marine helicopter landing pad of a marine engineering structure is proposed, including a helipad deck, guides forming a hemisphere with horizontal position limiters, ballast and a frame or three-dimensional structure that combines these elements, moreover, the helicopter landing pad is rotary in a vertical plane and is installed, resting on guides, on a support column rigidly fixed to the hull or superstructure of the offshore engineering structure, with formation of a hinge assembly. If the helicopter landing pad in manufactured with a water displacement design, it becomes an additional rescue tool.

EFFECT: marine helipad is proposed.
