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.

Holding the pipeline on Solitaire are three tensioners, which control the powerful forces on the pipe itself.

Pipe laying Methods

Innovation and new technology is central to Allseas’ philosophy. In Novembera Kongsberg sub-contractor Servie pulled up to 20 kilometres of cable while the ship was operating off of Egypt.

General characteristics Solitaire Length overall incl. You can sense the pride they have in this ship. A recent upgrade of Solitaire’s Kongsberg DP and automated vessel management system tested the flexibility of supplier and customer. In she set the world record for ultra-deepwater pipeline installation, laying pipe to a depth of solitajre, m 9, ft in the Gulf of Mexico.

J-Lay barges have a tall tower on the stern to weld and slip prewelded pipe sections.

Once they’re in place, the solitairw will have improved workability, with thrust in a more effective location. Horizontal reels lay pipe with an S-Lay configuration.


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.

This required some additional safety and security measures, but the time saved was invaluable. Nord Stream Pipeline – Pipelaying Processes.

The refit of Allseas Solitaire. That didn’t work out, so we had moved the job to late The bridge teams are particularly excited about the functionality that they have discovered in the newer ship control systems.

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. Nord Stream Pipeline – Preparation for pipe laying. Pipelines are assembled at an onshore spool-base facility and spooled onto a reel which is mounted on the deck of a pipelay barge. 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.

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 lalseas Allseas enable its ships to install larger pipe, deeper than conventional J-Lay competitors. From 2 to 60in OD Pipe hold capacity: Work in the yard took place over seven weeks. With one question of timing when? A tension control master system monitors the tensioners and provides solitaige single input to the DP system, solitsire responds with the necessary thrust.


Pipe laying of the 1, kilometre long Nord Stream Pipeline started in April 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. Nord Stream Pipeline – Introduction Part 2: To avoid buckling of the pipe, a tensioner must be used to provide appropriate tensile load to the pipeline Clauss, InAllseas began preparations to install the two new thrusters, and it became immediately clear that the Soligaire system would need modification.

Since then, Allseas has returned to Kongsberg for each of its subsequent pipe-layers, including Solitaire, which was completed in the mids.

Nord Stream Pipeline allxeas Introduction.

Nord Stream Pipeline – Logistics by the Numbers. Vertical reels most commonly do J-Lay, but can also S-Lay. Allseas’ relationship with Kongsberg has always been tight. This ship has set countless records both for speed and depth of pipelaying most recently, at metres.
