Audacia is 225 m long, which in terms of size places her between Allseas’ DP pipelay vessels Lorelay and Solitaire. She is optimised for the execution of small to large diameter pipelay projects of any length in all water depths.
The concept for Audacia was developed entirely in-house by Allseas. Her ship-shape allows for a high transit speed and gives her excellent workability, while a large pipe storage capacity makes her less dependent on offshore supply.
Operating on full dynamic positioning, with a stinger positioned at her bow, Audacia offers the safest pipelay method in congested areas where anchors could endanger the integrity of existing pipelines. Pipeline start-ups and lay-downs are executed in very quick time ensuring any disruption to other activities near platforms is minimised.
Audacia conversion 2006 - 2007
In June 2005 Allseas announced that it would be building a new 225 m long 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, Rozenburg, 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.
