Abstract

The invention relates to the field of offshore oil drilling and production equipment, and specifically discloses an umbilical cable deployment and underwater docking device, including an upper assembly, a lower assembly and a panel assembly. The umbilical hydraulic interface and the umbilical power interface; the lower assembly is used to connect the blowout preventer; the panel assembly is used to connect the blowout preventer, on which there is an underwater hydraulic flying lead interface connected with the underwater hydraulic flying lead and an underwater hydraulic flying lead interface. The underwater power flying lead interface for the power flying lead connection. The invention is composed of three parts: the upper assembly, the lower assembly and the panel assembly, and is connected with the underwater Christmas tree through the underwater hydraulic flying line and the underwater electric flying line. The power flying line is detached from the Christmas tree and temporarily stored in the panel assembly. The upper assembly is recovered together with the tubing hanger, and the lower assembly is recovered together with the blowout preventer. The recovery operation is simple and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of offshore oil drilling and production equipment, and particularly relates to an umbilical cable deployment and an underwater docking device. Background technique [0002] If the umbilical or terminal assembly fails for any reason, the marine riser, blowout preventer and / or low-level marine riser assembly must be fully retracted from the seabed to the surface of the drill floor to access and repair the umbilical. This recovery operation requires a lot of work and takes a lot of time, and is therefore time-consuming and expensive. Thus, for many years there has been a need for a method to effectively and efficiently separate the installation and workover control system umbilicals from the drilling riser. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide an umbilical cable deployment...
