Problems solved by technology

[0003] Although J-shaped laying improves the safety performance of the riser lowering process, there is a problem of low laying efficiency
Since the riser needs to complete the work of welding-non-destructive testing-coating-down on the laying tower during the J-type laying process, and these processes cannot be carried out simultaneously, and are limited by the number of equipment, the typical J-type laying speed is 1-1.5 km / day, resulting in higher riser installation costs

Abstract

The invention provides a deep-water quick J-type laying system, comprising a laying column, a laying column angle adjusting system, a J-type laying segment conveying system, and J-type laying related equipment. The laying column angle adjusting system mainly comprises an A-shaped frame, an angle adjuster and a hydraulic cylinder, the J-type laying segment conveying system comprises a horizontal conveying system, a loading arm, a rotating arm and an elevator; the J-type laying related equipment generally comprises a centering unit, a welding station and a moving platform. It is possible to provide a 1*4 node (one 4-node segment is laid on the laying tower, and each 4-node segment is 48.8 m in length) laying mode at the premise of controlled height of the laying tower, and by optimizing equipment structure and layout, the laying speed is 80.2% higher than typical J-lay speed of 1.5 km / d and laying cost is reduced.

Description

technical field [0001] The invention relates to a laying system, in particular to a deep-water J-shaped rapid laying system, which is applied to the laying of deep-water and ultra-deep-water submarine pipelines and standpipes. Background technique [0002] In the past few decades, deepwater pipelay technology has developed at an unimaginable speed. Now it is possible to develop oil and gas resources at a depth of more than 10,000 feet, but this is not the limit. The world's offshore oil continues to develop into deep water, and the technical requirements for deep water pipeline laying are also getting higher and higher. The rapid development of the world's offshore oil industry has promoted the rapid development of deep-water pipe-laying technology, and also led to the rapid development of crane pipe-laying vessel equipment. At present, in deep water projects, there are three main laying methods of pipelines: S-laying, reel laying and J-laying. J-shaped laying is a new pip...
