The invention discloses an offshore maneuvering type mounting platform based on captive balloons. The offshore maneuvering type mounting platform comprises a captive balloon system, a maneuvering typecaptive balloon library, a balloon collecting and releasing system, a captive balloon guaranteeing system and a ship platform, wherein the maneuvering captive balloon library and the ship platform are arranged on ship equipment; the balloon collecting and releasing system and the captive balloon guaranteeing system are arranged in the maneuvering type captive balloon library, and the captive balloon system is connected with the interior of the maneuvering type captive balloon library through a tethered cable. The invention provides a novel aerial task load mounting form for offshore operation, and the offshore maneuvering mounting platform capable of cruising at fixed points for a long time is built through the combination of the long-term stagnation characteristic of the captive balloonsand the movable characteristic of the ship equipment.
