Pipelay vessel Solitaire Allseas
The Solitaire, just outside Killybegs.
Solitaire, the largest pipelay vessel in the world, has set new standards in the pipelay industry. Based on the same principles as Lorelay, her ship-shape provides excellent workability. She has a pipe carrying capacity of 22000 t, making her less dependent on offshore pipe supply in hostile areas. Precise manoeuvring on full dynamic positioning allows the vessel to work safely in congested areas. Her high cruising speed and lay speed make her very competitive worldwide.
The vessel has been operational since 1998 and has since steadily improved her performance. A lay speed of over 9 km a day has been achieved, operating the in-house developed Phoenix automatic welding system.
She has laid numerous deepwater pipelines and holds a deepwater pipelay record in 2775 m (9100’). Her S-lay capacity was increased in 2005 to a holding force of 1050 t, enabling her to lay the heaviest pipelines.
