Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of oil drilling platform, and particularly relates to a hydraulic electric riser extension device. BACKGROUND

[0002] In the operation of an oil drilling platform, a seawater lifting pump is used to extract seawater for firefighting and other purposes. In order to ensure that seawater can be effectively extracted to the platform, the water lifting pipe needs to be gradually extended downward from the wellhead on the platform until the end of the pipe is submerged in seawater. The traditional method is to suspend an electric hoist on the structural beam above the water lifting pipe, and to realize the up-and-down movement of the water lifting pipe by operating the electric hoist. However, this method has obvious disadvantages, for example, the water lifting pipe may swing greatly during movement, which not only easily causes collision with the wellhead, but also accelerates corrosion in the high-salt and high-humidity marine environment due to paint peeling, thereby shortening the service life of the water lifting pipe. In addition, manual suspension is required before each use of the electric hoist, which is not only inefficient, but also has the risk of unstable suspension, which may cause the water lifting pipe to fall during operation. More importantly, the existing electric hoist solution cannot quickly stop the water lifting pipe in an emergency, and cannot effectively respond to possible emergencies. SUMMARY
