Solitaire (ship) – Wikipedia

Work in the yard took place over seven weeks. In Novembera Kongsberg sub-contractor Servie pulled up to 20 kilometres of cable while the ship was operating off of Egypt.

In the J-lay methodthe pipe is dropped down almost vertically until it reaches touchdown; after that it assumes the “J” shaped curve. Horizontal reels lay pipe with an S-Lay configuration. 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 solitaite deeper waters.

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. Headquarters Offices around the world Local sales representatives Human resources Management Media contacts. 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.

In this case, though, the crew was pushing us to double-check everything. 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. Shortly after Allseas was founded init began exploring designs for a DP-controlled pipelay vessel.

This method is used for pipeline installations in a range of water depths from shallow to deep. Alldeas approximately 7, hours of work onboard, Kongsberg’s teams wrapped up their work on 22 April with the completion of the customer acceptance tests.

Innovation and new technology is central to Allseas’ philosophy. This crew puts its honour into solitairre ship; it’s their home. Nord Stream Pipeline – Preparation for pipe laying Part 3: Pipelines are assembled at an onshore spool-base facility and spooled onto a reel which is mounted on the deck of a pipelay barge.

Solitaire’s high cruising speed, high laying speed and substantial carrying capacity make her highly competitive for pipelay solitaiire anywhere in the world.

A study in flexibility: The refit of Allseas Solitaire

Since then, Allseas has returned to Kongsberg for each of its subsequent pipe-layers, including Solitaire, which so,itaire completed in the mids. You can sense the pride they have in this ship. The bridge teams are particularly excited about the functionality that they have discovered in the newer ship control systems.

Accurate positioning is critical, as too little forward thrust would lead the pipeline to buckle near the seabed and too much forward thrust burns too much fuel and strains the tensioners. Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay industry. The answer was two additional thrusters in the ship’s aft.

Nord Stream Pipeline – Introduction.

In she set the world record for ultra-deepwater pipeline installation, laying aallseas to a depth of 2, m 9, ft in the Gulf of Mexico. Eager to increase the ship’s capabilities, Allseas doubled Solitaire’s tensioner capacity in 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.

A recent upgrade of Solitaire’s Kongsberg DP and automated vessel management system tested the flexibility of supplier and customer. In FebruaryAllseas’ Solitaire steamed to the port of Rotterdam for an express refitting of its DP and automation systems.

Pipe laying Methods

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 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. Often, we have to ask crews to do this, and they comply grudgingly. Nord Stream Pipeline – Preparation for pipe laying.

This ship has set countless records both for speed and depth of pipelaying most recently, at metres.

The conclusion was that the DP and automation systems would need upgrading,” said Skullerud. Three pipe-laying barges were commissioned to work on the project:. Nord Stream Pipeline – Pipelaying Processes. It’s also a result of the management. Skullerud, who spent 53 nights on the ship in Rotterdam, gives much credit to Solitaire’s crew. This required some additional safety and security measures, but the time saved was invaluable. 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.

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.

Pipeline start-ups and lay-downs are executed in very quick time ensuring that any disruption to other activities near platforms is minimised. 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.
