Underwater umbilical cable terminal base plate device

Abstract

The invention discloses an underwater umbilical cable terminal base plate device which comprises a slab foundation, a supporting platform installed on the slab foundation, rigid arms, a rear limiting block, a front limiting block and a protective cover arranged on the supporting platform. The rigid arms, the rear limiting block and the front limiting block are installed on the slab foundation. An umbilical cable terminal device support is arranged on the supporting platform, the two sides of the slab foundation are respectively provided with a pin shaft supporting base, and two supporting base lifting lugs pivoted to the rigid arms through pin shafts are arranged on the pin shaft supporting bases. Each rigid arm is mainly of a U-shaped pipe structure. The upper portion and the lower portion of the U-shaped pipe are provided with lifting lugs respectively. The front limiting block is arranged at the front end of the slab foundation, and the rear limiting block is arranged at the rear end of the slab foundation. The underwater umbilical cable terminal base plate device and umbilical cables can be laid and installed together, and operations such as underwater complex abutting connection and locking are avoided. In addition, the lower umbilical cable is prevented from being excessively bent, and the requirement for umbilical cable installation bent radius is met; an umbilical cable terminal can be prevented from being impacted and damaged by fallen objects, and the umbilical cable terminal device is effectively protected.

Description

technical field [0001] The invention relates to an underwater umbilical cable, in particular to an underwater umbilical cable terminal template device suitable for the development of offshore oil and gas fields. It belongs to the field of offshore oil engineering. Background technique [0002] The underwater production system is widely used in the development of offshore oil and gas fields, and the underwater umbilical cable is the channel for controlling the underwater production system. The umbilical cable terminal equipment is the underwater distribution unit of the umbilical cable, which can realize various Hydraulic, electrical distribution, signal transmission and other control functions of the facilities. The underwater umbilical cable is laid and installed by the offshore engineering vessel, and the umbilical cable terminal equipment is installed at one end of the umbilical cable and lowered together with the laying of the umbilical cable. [0003] Due to the simpl...

AI Technical Summary

Problems solved by technology

[0003] Due to the simple and compact shape of the existing umbilical cable terminal equipment, it cannot bear its own weight when placed on the soil on the seabed, and other structures or devices are needed for support. At the same time, if it is close to the water surface facilities such as platforms, there will be impacts from falling objects on the platform into the water risk, other structures need to be set up to protect terminal equipment
