Offshore pipeline lowering rotary guide device

Abstract

A rotary guiding device for lowering an offshore pipeline, which relates to the technical field of offshore pipeline laying engineering, includes a rotary guiding mechanism and an auxiliary guiding mechanism; Two pinch roller groups are symmetrically arranged on both sides; a friction layer is arranged on the outer circumference of the pinch roller; the roller shaft of the pinch roller is connected with the rotating driving device; There are symmetrically arranged rotating shafts, and the two rotating shafts are connected with the rotating drive device; the auxiliary guiding mechanism includes an adjustment base, on which a swing frame is arranged, and the lower part of the swing frame is rotatably installed on the adjustment base through the rotating shaft , the rotating shaft and the rotating shaft are arranged in parallel; an auxiliary ring is arranged on the upper part of the swing frame, and a traction wire rope is arranged on the hull, and the traction wire rope is connected with the auxiliary ring. The invention can effectively adjust the pipe laying direction, has high construction flexibility, good construction quality and high safety.

Description

technical field [0001] The invention relates to the technical field of offshore pipeline laying engineering, in particular to a rotary guide device for laying down offshore pipelines. Background technique [0002] At present, the equipment for pipeline laying operations at sea is mainly a special-purpose ship for pipeline laying. The existing laying devices for offshore pipelines cannot effectively adjust the laying direction of the pipeline during the pipeline laying process. In the complex construction water environment, it is difficult to achieve Good construction effect, and poor construction flexibility, unable to adjust and optimize the direction of pipeline laying according to changes in environmental conditions. At present, the construction machinery and equipment used for offshore pipeline laying are mainly pipeline laying ships. After passing through the tensioner, the pipeline is lowered into the water, so that the pipeline is laid on the seabed, and the laying an...

AI Technical Summary

Problems solved by technology

Under deep water conditions, the situation of offshore pipeline laying operations is more complicated, and it is difficult for pipeline laying ships to make real-time adjustments according to changes in underwater conditions, which may lead to problems in the quality of pipeline laying

[0003] Aiming at the problem that the existing pipeline installation device cannot effectively adjust the direction of pipeline lowering, and cannot make adaptive adjustments to the direction of pipeline laying, a fully rotating guide device that can effectively adjust the direction of pipeline lowering during the process of pipeline laying is needed
