Audacia

Audacia  is Allseasí latest pipelay vessel. Operational since December 2007, she is optimised for the execution of small to large diameter pipeline projects of any length in all water depths, and for associated work such as the installation of risers and subsea protection frames.

Audacia  is 225 m long, which in terms of size places her between Allseasí DP pipelay vessels Lorelay  and Solitaire. Precise manoeuvring on full dynamic positioning (DP) with a stinger positioned on the bow allow Audacia  to work safely in congested areas and lay pipe in very deep water.
Pipeline start-ups and lay-downs are executed in very quick time ensuring any disruption to other activities near platforms is minimised.

Due to her long length and ship shape, Audacia  can accommodate multiple work stations and has a greater pipe hold capacity, and her independence from anchor handlers and large buffer capacity ensure she is less dependent on offshore pipe supply.
Her high transit speed, high lay speed and large carrying capacity make Audacia  highly competitive for pipelay projects anywhere in the world.

Audacia  conversion 2006 - 2007

The concept for Audacia  was developed entirely in-house by Allseas. In June 2005 Allseas announced that it would be building a new 225-m DP pipelay vessel, to be named Audacia.
Two months later, the Panamax type bulk carrier "Geeview"  was procured.

The "Geeview"  finally arrived at the Keppel Verolme shipyard, Rotterdam, the Netherlands, in December 2005 and work to convert her into a pipelay vessel commenced in January 2006.
Audacia  left Keppel Verolme for sea trials in the North Sea in late September 2007 and successfully completed her maiden pipelay project in early December 2007.
