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.

This crew puts its honour into the ship; it’s their home. Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay industry. Preparatory work, including cable-pulling, took place off of Egypt while the ship was in operation. Eager to increase slitaire ship’s capabilities, Allseas doubled Solitaire’s tensioner capacity in Precise manoeuvring on full dynamic positioning DP allows Solitaire to work safely in congested areas and lay pipes in very deep water.
Nord Stream Pipeline – Pipelaying Processes. Once they’re in place, the vessel splitaire have improved workability, with thrust in a more effective location.
A study in flexibility: The refit of Allseas Solitaire
allswas InAllseas began preparations to install the two new thrusters, and it became immediately clear that the DP system would need modification. Making DP pipe-laying operations possible 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.
After approximately 7, hours of work onboard, Kongsberg’s teams wrapped up their work on 22 April soljtaire the completion of the customer acceptance tests. The new thrusters will be added later this year.
Pipelines are assembled at an onshore spool-base facility and spooled onto a reel which is mounted on the deck of a pipelay barge. To counter the added weight, extra buoyancy was added to the ship’s aft. In this case, though, the crew was pushing us to double-check everything.
This will hardly be the final ambitious project for a company that has made a living of doing what none have done before. It’s also a result of the management. 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.
Innovation and new technology is central to Allseas’ philosophy. The answer was two additional thrusters in the ship’s aft.
In the Reel-Lay methodthe pipeline is installed from a huge reel mounted on an offshore vessel. Solitaire has laid numerous deepwater pipelines.
Nord Stream Pipeline – Preparation for pipe laying. To reduce bending stress in the pipe, a stinger is used to support the pipe as it leaves the barge. Main firing line with 5 welding stations for double joints, 1 NDT station and 4 coating stations.
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.
Solitaire’s high cruising speed, high laying speed and substantial carrying capacity make her highly competitive for pipelay projects anywhere in the world.

The timing of this job had changed numerous times in the preceding months, most recently in January. The engineers and electricians know every cable on the ship, every termination. Three pipe-laying barges were commissioned to work on the project:.
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. In the J-lay methodthe pipe is dropped down almost vertically until it reaches touchdown; after that it assumes the “J” shaped curve. 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.
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. Saipem’s Castoro Sei – for the majority of the route in the Baltic Sea Saipem’s Castoro Dieci – for the shallow waters in Germany Allseas Solitaire – for pipe laying in the Gulf of Finland Solitaire is the largest pipelaying vessel in the world soliraire has set new standards in the sokitaire industry.
The DP system onboard combines the thrust available with the force created by the pull of the pipeline to keep the vessel in position, and move forward.
That didn’t work out, so we had moved the job to late 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.
The presence of the ship’s crew alleeas the commissioning work was both intentional and beneficial. Since then, Allseas has returned to Kongsberg for each of its subsequent pipe-layers, including Solitaire, which was completed in the mids. This method is used for pipeline installations in a range of water depths from shallow to deep.

This ship solitwire set countless records both for speed and depth of pipelaying most recently, at metres. Holding the pipeline on Solitaire are three tensioners, which control the powerful forces on the pipe itself. Contact us More information Phone: This, in addition to an elongated stinger, allows Solitaire to lay heavier pipes in deeper waters.
