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
The answer was two additional thrusters in the ship’s aft. It’s also a result of the management.
Three pipe-laying barges were commissioned to work on the project: Pipeline start-ups and lay-downs are executed sllseas very quick time ensuring that any disruption to other activities near platforms is minimised. Allseas’ relationship with Kongsberg has always been tight. 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 FebruaryAllseas’ Solitaire steamed to the port of Rotterdam for an express refitting of its DP and automation systems.
Nord Stream Pipeline – Preparation for pipe laying. In the Reel-Lay methodthe pipeline is installed from a huge reel mounted on an offshore vessel. Solitaire, the world’s biggest pipelay vessel, recently upgraded DP and automated vessel management systems. Solitaire’s high cruising speed, high laying speed and substantial carrying capacity make her highly competitive for pipelay projects anywhere in the world.
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. The conclusion was that the DP and automation systems would need upgrading,” said Skullerud. A recent upgrade of Solitaire’s Kongsberg DP and automated vessel management system tested the flexibility of supplier and customer.
Pipe laying of the 1, kilometre long Nord Stream Pipeline started in April 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 and has set new standards in the pipelay industry.
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. The new thrusters will be added later this year.

As many as two dozen people on Kongsberg’s team lived and worked from the 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.
A novelty at the time, the logic behind it was allseass in competition with anchored pipelay barges and platforms, a DP pipelayer could work much faster and more efficiently. 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. General characteristics Solitaire Length overall incl.
InAllseas began preparations to install the two new thrusters, and it became immediately allseae that the DP system would need modification.
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. 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.
Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay industry. Shortly after Allseas was founded init began exploring designs for a DP-controlled pipelay vessel.

This crew puts its honour into the ship; it’s their home. To avoid buckling of the pipe, a tensioner must be used to provide appropriate tensile load to the pipeline Clauss, As Solitaire, the world’s solitaier pipelay vessel, rushes from job to job, the ship’s technical team must squeeze vital refits into the slimmest of openings.
Upon Solitaire’s arrival at the Rotterdam shipyard, Kongsberg’s team of between 19 and 23 technicians and engineers moved onboard. There are only three of us in the alllseas department, who work with this vessel from shore,” said Pesman. The bridge teams are particularly excited about the functionality that they have discovered in the newer ship control systems. Three pipe-laying barges were commissioned to work on the project:. Eager to increase the ship’s capabilities, Allseas doubled Solitaire’s tensioner capacity in This required some additional safety and security measures, but the time saved was invaluable.
