Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay Nord Stream Pipeline – Pipe Laying Vessel – Allseas Solitaire. In February , Allseas’ Solitaire steamed to the port of Rotterdam for an express refitting of its DP and automation systems. The timing of this job had. SOLITAIRE – Pipe Layer Vessel SOLITAIRE (IMO: , MMSI: ) is a Pipe Layer built in Nord Stream 2 Awards Pipelay Contract to Allseas.

Pipe laying Methods
Upon Solitaire’s arrival at the Rotterdam shipyard, Kongsberg’s team of between 19 and 23 technicians and engineers moved onboard. A tension control master system monitors the tensioners and provides a single input to the DP system, which responds with the necessary thrust.
With one question of timing when?
The answer allsess two additional thrusters in the ship’s aft. In FebruaryAllseas’ Solitaire steamed to the port of Rotterdam for an express refitting of its DP and automation systems. Although some minor issues remain to be settled including an adjustment after the two thrusters are installed later this yearthe Solitaire refit can be classified as a success.
This will hardly be the final ambitious project for a company that has made a living of doing what none have done before. In she set the world record for ultra-deepwater pipeline installation, laying pipe to a depth of 2, m 9, ft in the Gulf of Mexico.
Nord Stream Pipeline – Allseas Solitaire, the largest pipelay vessel in the world
Three pipe-laying barges were commissioned to work on the project:. The conclusion was that the DP and automation systems would need upgrading,” said Skullerud. To counter the added weight, extra buoyancy was added to the ship’s aft.
To avoid buckling of the pipe, a tensioner must be used to provide appropriate tensile load to the pipeline Clauss, Main firing line with 5 welding stations for double joints, 1 NDT station and 4 coating stations. Once they’re in place, the vessel will have improved workability, with thrust in a more effective location.
Operational since and optimised for laying medium and large diameter pipelines at high speed, she is highly competitive for pipelay projects anywhere in the world. Eager to increase the ship’s capabilities, Allseas doubled Solitaire’s tensioner capacity in Three pipe-laying barges were commissioned to work on the project: Shortly after Allseas was founded init began exploring designs for a DP-controlled pipelay vessel.
The refit of Allseas Solitaire. Saipem’s barge uses the J-Lay method In the Reel-Lay methodthe pipeline is installed from a huge reel mounted on an offshore vessel.
You can sense the pride they have in this ship. As a result of the large number of welding stations on board, Solitaire is capable of installing over 1, km of pipeline in a single year, while her average pipelaying speed on large projects is almost double that of the largest competing lay vessels. Sometimes for the sake of expediency, sometimes out of necessity, the teams responsible for the refit lived onboard Solitaire, which can house a total of people.
Vertical reels most commonly do J-Lay, but can also S-Lay. General characteristics Solitaire Length overall solihaire. Pipe laying of the 1, kilometre long Nord Stream Pipeline started in April Nord Stream Pipeline – Pipelaying Processes. There are only three of us in the technical department, who work with this vessel from shore,” said Pesman.
In Novembera Kongsberg sub-contractor Servie pulled up to 20 kilometres of solihaire while the ship was operating off of Egypt. Solitaire’s high cruising speed, high laying speed and substantial carrying capacity make her highly competitive for pipelay projects anywhere in the world. Innovation and new technology is central to Allseas’ philosophy. The DP system onboard combines the thrust available dolitaire the force created by the pull of the pipeline to keep the vessel in position, and move solitairw.
A study in flexibility: The refit of Allseas Solitaire
Due to her length and ship shape, she can accommodate multiple work stations and a greater pipe hold capacity, while her independence from anchor handlers and large buffer capacity ensure she is less reliant on offshore pipe supply.
Nord Stream Pipeline – Preparation for pipe laying Part 3: For a technical superintendent like Pesman, who must keep all the new technology maintained and spare parts in stock, it is surely priceless to have a flexible partner who delivers on its promises.
Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay industry. This ship has set countless records both for speed and depth of pipelaying most recently, at metres.
Nord Stream Pipeline – Logistics by the Numbers. Nord Stream Pipeline – Preparation for pipe laying. Preparatory work, including cable-pulling, took place off of Egypt while the ship was in operation.
In the end, Kongsberg completed the project in roughly seven weeks, according to the tight schedule, and Pesman lauded the professionalism, flexibility and speed of Skullerud and the Kongsberg team. Solitaire has laid numerous deepwater pipelines.
Sharing a ship and a vision Sometimes for the sake of expediency, sometimes out of necessity, the teams responsible for the refit lived onboard Solitaire, which can house a total of people.
The engineers and electricians know every cable on the ship, every termination. In the J-lay methodthe pipe is dropped down almost vertically until it reaches touchdown; after that it assumes the “J” shaped curve. That didn’t work out, so we had moved the job to late The S-Lay style pipelay systems assembling the pipeline horizontally before lowering it down to the sea bed favoured by Allseas enable its ships to install larger pipe, deeper than conventional J-Lay competitors. Nord Stream Pipeline allseaas Introduction Part 2: With the simpler pipeline shape, the J-Lay method avoids some of the difficulties of S-Laying such as tensile load forward thrust, and can be used in deeper waters.
These teams slowly moved the ship’s operations from the older systems to the newly installed systems, all without using shore power and with personnel living aboard the ship. This, in addition to an elongated stinger, allows Solitaire to lay solitqire pipes in deeper waters. Horizontal reels lay pipe with an S-Lay configuration. Skullerud also admired the crew’s attitude and knowledge:
