Solitaire is the largest pipelaying vessel in the world and has set new standards in the pipelay industry. Operational since 1998 and optimised for laying medium and large diameter pipelines at high speed, she is highly competitive for pipelay projects anywhere in the world.
Based on the same principles as Lorelay, her long length and ship-shape provide excellent workability. Solitaiare can accommodate multiple work stations and a greater pipe capacity in the holds, while precise manoeuvring on full dynamic positioning (DP) allow her to work safely in congested areas and lay pipes in very deep water.
Precise manoeuvring on full dynamic positioning (DP) allows Solitaire to work safely in congested areas and a pipe carrying capacity of 22,000 t ensures she is less dependent on offshore pipe supply in hostile areas.
Solitaire has achieved pipelay speeds in excess of 9 km/day, operating the latest version of Phoenix, the automatic welding system developed and manufactured in-house by Allseas. As a result of the large number of welding stations on board, Solitaire is capable of installing over 1,000 km of pipeline in a single year, while her average pipelaying speed on large projects is close to double that of the largest competing lay vessels.
Solitaire has laid numerous deepwater pipelines. In 2007 she set the world record for ultra-deepwater pipeline installation by laying pipe at a depth of 2,775 m (9,100 ft). In 2005 her S-lay capacity was increased to a holding force of 1,050 t (2,316 kips), enabling her to lay the heaviest pipelines. Combining her high cruising speed, high laying speed and substantial carrying capacity make Solitaire highly competitive for pipelay projects anywhere in the world.
