Abstract

The invention discloses a BOP transfer device suitable for deep-sea floating drilling, which includes a base body and a guide rail arranged on the hull, the base body can move relative to the hull along the guide rail, and a drive motor is arranged on the base body. The driving shaft of the driving motor is provided with a driving gear, and the hull is provided with a rack parallel to the extending direction of the guide rail, and the gear and the rack cooperate with each other, and the rack and pinion mechanism is used to carry the substrate, and the BOP is transported by the substrate, It occupies a small space; and through the meshing of the rack and pinion, it can prevent the natural slip and deflection of the base due to the movement of the hull, and the reliability is stronger.

Description

technical field [0001] The invention relates to offshore operation equipment, in particular to a BOP transfer device suitable for deep sea floating drilling. Background technique [0002] BOP (Blowout Preventer) is a very critical blowout prevention and well control equipment in deep sea floating drilling exploration wells. The main structure of BOP is mainly to withstand high pressure. The internal key components are valves and gates. Connection, the flange can bear the weight of the entire BOP, and is used for the lowering operation of the BOP. After the BOP is connected to the riser and the LMRP used to connect the BOP and the riser, it can be lowered into seawater. [0003] Due to the influence of the overall layout of the hull or platform, bop and lmrp are arranged at both ends of the moon pool, and can only be hoisted into the wellhead from one end of the moon pool. Therefore, before the BOP works, it is necessary to store the BOP on the deck of the hull. When it is u...
