A kind of laying method of glass fiber reinforced flexible pipe

Abstract

The invention discloses a laying method of a glass fiber reinforced flexible pipe. The laying method is applied to a pipe laying ship, wherein the pipe laying ship comprises a roller, a tensioner, balancing weight mounting equipment and a stinger. The method comprises the following steps: transporting the glass fiber reinforced flexible pipe to the pipe laying ship and winding on the roller; locating the pipe laying ship on a target position, and adjusting the stinger; moving the pipe laying ship; pulling the glass fiber reinforced flexible pipe from the roller to the tensioner; pulling the glass fiber reinforced flexible pipe passing through the tensioner to the balancing weight mounting equipment, and mounting a balancing weight; enabling the glass fiber reinforced flexible pipe equippedwith the balancing weight to pass through the stinger; laying the glass fiber reinforced flexible pipe with the balancing weight down to seabed. By adopting the balancing weight on the glass fiber reinforced flexible pipe, the floatation and instability during mounting and in-place arrangement are avoided; with the stinger and the horizontal tensioner, the tension of the glass fiber reinforced flexible pipe is reduced, and the laying safety is improved.

Description

technical field [0001] The invention relates to the technical field of submarine pipelines, in particular to a method for laying glass fiber reinforced flexible pipes. Background technique [0002] Submarine pipeline is the main component of the development and production system of offshore oil and gas resources, which can transport oil and gas quickly, safely and economically. At present, the transportation of oil and natural gas mainly relies on steel pipelines. Due to the strong corrosion of steel in the environment of marine pipelines and the moisture contained in the oil and gas medium, steel pipelines face serious corrosion problems. The installation methods of offshore pipelines mainly include the S-type pipe-laying ship method, the J-type pipe-laying ship method, and the R-type pipe-laying ship method. Among them, the R-type pipe-laying vessel is suitable for laying continuous pipes; the S-type pipe-laying vessel’s tensioner is placed horizontally, which effectively...
