The invention discloses a deep sea well drilling blowout preventer transferring crane. The deep sea well drilling blowout preventer transferring crane comprises a support structure; the bottom end ofthe support structure is connected with a rolling wheel assembly; the bottom end of the rolling wheel assembly is connected with a main guide rail; the support structure, the rolling wheel assembly and the main guide rail form a moving pair; two fixed supporting bases are oppositely connected to the upper end of the support structure; a first steel wire rope winch driven by a hydraulic motor is connected to each fixed supporting base; each first steel wire rope winch is provided with a first steel wire rope extending downwards; the bottom end of each first steel wire rope is connected with a first travelling block; and the bottom end of each first traveling block is connected with a hoisting lug. According to the deep sea well drilling blowout preventer transferring crane, a blowout preventer can be safely and reliably hoisted / put down, and is transferred back and forth between a deck storing area and a moonpool; transferring is steady, operation is easy, and the operation precision ishigh; and transferring operation can also be performed on Christmas trees and other underwater devices.
Description
Technical field [0001] The invention belongs to the technical field of handling equipment, and specifically relates to a deep-sea drilling blowout preventer moving crane. Background technique [0002] When the semi-submersible platform is used for oil and gas exploitation, the underwater blowout preventer is a very critical well control equipment for blowout prevention. During the drilling process, the blowout preventer needs to be lowered underwater to connect with the underwater wellhead. Due to the large size of the underwater blowout preventer, it is usually stored on the side of the moon pool during the overall layout of the platform. When carrying it, the blowout preventer is first lifted by a lifting device and transported to one end of the moon pool. The transport vehicle straddling the moonpool transports it to the designated location, the blowout preventer is connected with the riser, and the drilling hoisting system completes the lowering operation. [0003] When liftin...
