Abstract

The invention discloses a deployment and recovery system and method suitable for surface blowout preventers combined with seabed blowout preventers. Right above the moon pool, there are trolley rails on both sides of the inner top of the moon pool. The upper end of the hull is longitudinally provided with the first longitudinal rail, the second longitudinal rail and the third longitudinal rail from left to right. The upper end of the hull is horizontally A first transverse track is provided, and the first transverse track communicates with the first longitudinal track and the second longitudinal track, and the first suspension beam and the second suspension beam are longitudinally arranged between the trolley tracks. The present invention realizes deployment and recovery applicable to surface BOP groups and subsea BOP groups with as few equipment combinations as possible; compared with traditional BOP group processing methods, there is no need for BOP group gantry cranes, occupying an area Small, compact and easy to expand.

Description

technical field [0001] The invention relates to the technical field of deepwater drilling, in particular to a deployment and recovery system and method suitable for surface blowout preventers combined with subsea blowout preventer groups. Background technique [0002] The exploration and development of oil and gas resources has moved from shallow water to deep water and ultra-deep water; deep water drilling technology and equipment have become the development direction. The blowout preventer group is a safety guarantee for drilling operations and a barrier to prevent and control blowout accidents. [0003] The BOP group can be divided into two categories according to the operating position: the surface BOP group arranged above the water surface and the subsea BOP group arranged underwater. The two operating positions bring about a great difference in the composition of the deployed recovery system. [0004] The traditional deployment and recovery system is: using the combi...
