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 soliitaire world and has set new standards in the pipelay industry. This required some additional safety and security measures, but the time saved was invaluable.

In the J-lay methodthe pipe is dropped down almost vertically until it reaches touchdown; after that it assumes the “J” shaped curve. It’s also a result of the management. Three pipe-laying barges were commissioned to work on the project: General characteristics Solitaire Length overall incl. As many as two dozen people on Kongsberg’s team lived and worked from the ship.

Nord Stream Pipeline – Allseas Solitaire, the largest pipelay vessel in the world

Upon Solitaire’s arrival at the Rotterdam shipyard, Kongsberg’s team of between 19 and 23 technicians and engineers moved onboard. 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. 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.

With solitairs question of timing when? Although some minor issues remain to be settled including an xolitaire after the two thrusters are installed later this yearthe Solitaire refit can be classified as a success.

Often, we have to ask crews to do this, and they comply grudgingly. Listed by ship type Listed by industry Listed alphabetically Related information: Skullerud also admired the crew’s attitude and knowledge: Holding the pipeline on Solitaire are three tensioners, which control the powerful forces on the pipe itself.

Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay industry. 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 crew puts eolitaire honour into the ship; it’s their home. That didn’t work out, so we had moved the job to late To counter the added weight, extra buoyancy was added to the ship’s aft.

Pipe laying of the 1, kilometre long Nord Stream Pipeline started in April Saipem’s barge uses the J-Lay allseaz In the Reel-Lay methodthe pipeline is installed from a huge reel mounted on an offshore vessel. The answer was two additional thrusters in the ship’s aft.

Precise manoeuvring on full dynamic positioning DP allows Solitaire to work safely in congested areas and lay pipes in very deep water.

Pipe laying Methods

The conclusion was that the DP and automation systems would need upgrading,” said Skullerud. Solitaire’s high cruising speed, high laying speed and substantial carrying capacity make her highly competitive for pipelay projects anywhere in the world. The new thrusters will be added later this year. The contract was signed in Aprilengineering solitakre production lasted until the factory acceptance test in August and installation was done in phases from late to summer From 2 to 60in OD Pipe hold capacity: In the Reel-Lay methodthe pipeline is installed from a huge reel mounted on an offshore vessel.

This will hardly be the final ambitious project for a company that has made a living of doing what none have done solitxire. Due to her length and ship shape, she can accommodate multiple aolseas stations and a greater pipe hold capacity, while her independence from anchor handlers and large buffer capacity ensure solitairre is less reliant on offshore pipe supply. There are only three of us in the technical department, who work with this vessel from shore,” said Pesman.

Horizontal reels lay pipe with an S-Lay configuration. Skullerud, who spent 53 nights on the ship in Rotterdam, gives much credit to Solitaire’s crew.

Main firing line with 5 welding stations for double joints, 1 NDT station and 4 coating stations. In FebruaryAllseas’ Solitaire steamed to the port of Rotterdam for an express refitting of its DP and automation systems. As Solitaire, the world’s biggest pipelay vessel, rushes from job to job, the ship’s technical team must squeeze vital refits into the slimmest of openings.

Innovation and new technology is central to Allseas’ philosophy. 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. The DP system onboard combines the thrust available with solitwire force created by the pull of the pipeline to keep the vessel in position, and move forward.

Allseas’ relationship with Kongsberg has always been tight. The refit of Allseas Solitaire. Solitaire has laid numerous deepwater pipelines.
