A pipelaying ship is a maritime vessel used in the construction of subsea infrastructure. It serves to connect oil production platforms with refineries on shore. To accomplish this goal a typical pipelaying vessel carries a heavy lift crane, used to install pumps and valves, and equipment to lay pipe between subsea structures.
Pipeline installation. Allseas has installed over 20,000 km of subsea pipeline worldwide using S-lay technology, with diameters ranging from 2” to 48”. S-lay is characterised by its fast installation process and its application in all water depths. The “S” refers to the shape the pipe forms between the vessel and the seabed as it is laid.
jointly announced the award of a contract to Todd for the construction of the first self-propelled pipelaying reel ship. According to E.L. Shannon Jr., Santa Fe president, the vessel will cost approximately $28,000,000, including owner-furnished equipment, and it will be built at Todd's Galveston (Texas) Division for delivery in the second half
The invention relates to a marine pipelaying system comprising a vessel (1) provided with a pipeline launch tower (6). The tower (6) comprises pipe laying equipment defining a tower firing line, and is adapted for launching a pipeline (20) along the firing line into the sea.
May 07, 2017 · Pipes can be of different diameters and wall thicknesses depending on their usage. In terms of length of pipes used in pipelaying, there is some standardization. A single joint is generally 40 Ft (12.2 m) in length. There can also be double, triple, and quad joints with lengths 80, 120 and 160 Ft respectively.
Pipe laying of the 1,224 kilometre long Nord Stream Pipeline started in April 2010. Three pipe-laying barges were commissioned to work on the project.. Saipem's Castoro Sei - for the majority of the route in the Baltic Sea. The Castoro Sei provides a safe, reliable and stable operating platform capable of laying subsea pipelines up to 60 inches
Jan 02, 2013 · Pipe laying capacity is 12m for the triple joint or 18m for double joint, with pipe size up to 48in excluding coating. The overall length of the vessel excluding its ramp is 290m. Moulded breadth is 39m and transit draft is 6.5m, while minimum operational draft is 7m. Displacement of the vessel at maximum operational draft of 10m is 89,000t.
Pipelaying vessel is a specialized floating facility for submerged pipeline laying. It is widely used in offshore fields development for laying pipelines up to 1,420 millimeters in diameter down to 2,500 meters depth (Blue Stream gas pipeline). First pipelaying vessels were built in the 1940s and 1950s.
Laying pipe on the seafloor can pose a number of challenges, especially if the water is deep. There are three main ways that subsea pipe is laid -- S-lay, J-

Pipelaying Vessel. Pipelaying vessel (PLV) or pipelay vessel is a specialized floating facility for submerged pipeline laying. It is widely used in offshore fields development for laying pipelines up to 1,420 millimeters in diameter down to 2,500 meters depth. Submerged pipelines can be constructed on pipelaying vessels by stovepipe welding of
Over the last two decades IMECA developed Pipe Lay Systems for Flexible products, Rigid Pipes, Umbilical lines for key players. Recognized as the lightest systems with the lowest COG, High squeezing capacity over 200 Te/m, Firing line clearance of up to 2 m OD and up to 4 m with large opening systems, Early integration in the Vessel interface
Apr 02, 2021 · The Solitaire is one of the world’s largest pipe laying vessels, operated by the Dutch construction conglomerate Allseas. It was actually built in the 1970s in a Mitsubishi shipping yard as a cargo carrier with the name Trentwood. It was eventually sold to Allseas and in 1998, was re-christened the Solitaire and started pipe laying activity
Pipe Lay Vessels. Pipe Lay Vessels are purpose built or converted for major offshore construction activities and also have Reel-lay or I-lay equipment installed. Below is an extract from the DMC vessel database showing pipe lay vessels. We maintain a comprehensive database of these vessels, including specifications, current owners and general
Aug 03, 2020 · To improve conventional pipelaying design and analysis methodologies, a time domain vessel/stinger/pipeline Fully Coupled Analysis (FCA) is presented in this study. The new analysis procedure
