Abstract

The invention discloses a transfer device of a deepwater drill platform BOP (blowout preventer), which comprises guide rails arranged on a ship body, wherein a matrix is arranged on the guide rails; the matrix is provided with an accommodation space for accommodating BOP; the matrix can move along the guide rails between a deck and a borehole of the ship body; the ship body is further provided with a hoisting device for hoisting BOP; a pressure test device is arranged on the matrix; the pressure test device is connected with the matrix through a pressure test cylinder; and the pressure test device can be moved to the location having the same axis with the accommodation space under the driving action of the pressure test cylinder. By virtue of the movable matrix to store BOP, compared with the prior art, in which the fixed BOP storage area is arranged on the deck to store BOP, the storage location of BOP is more flexible when BOP is not required to participate in the working processes, such as drilling waiting and towing.

Description

technical field [0001] The invention relates to a transfer and storage device for offshore petroleum operation equipment, in particular to a BOP transfer device for a deep sea drilling platform. Background technique [0002] When deep-sea floating drilling exploration wells, the underwater BOP (blowout preventer) is a very critical blowout prevention and well control equipment. The main structure of the BOP is mainly to withstand high pressure. The internal key components are valves, gates, and Through the flange connection, the flange can bear the weight of the whole BOP, which is used for the lowering operation of the BOP. However, since other parts of the BOP cannot withstand large external forces, usually a BOP frame is placed on the BOP to guide and protect the BOP when it is lowered. It can not only support the entire weight of the air BOP, but also prevent the BOP from The main body collides with the hull due to the motion generated by the swaying of the hull. The B...
