Allseas pipelay vessel Audacia has arrived in Singapore for bunkering stop and crew change.

The vessel was previously working at Chevron's Gorgon Stage 2 (GS2) offshore Western Australia. The GS2 project includes offshore installation of 11 vertical subsea production trees, over 46 km of production pipelines, nearly 29 km of control umbilicals and 2,840 tonnes of subsea structures at Gorgon and Jansz-Io fields.

Allseas is responsible for work package one for GS2, which covers installation of 24-inch Gorgon and 18-inch Jansz-Io corrosion-resistant alloy production flowlines, 8-inch Gorgon and 6-inch Jansz-Io mono-ethylene glycol pipelines, and 6-inch Gorgon and 6-inch Jansz-Io utility pipelines, in addition to 12 pipeline end terminations. The package also includes supply, fabrication and installation of anti-burial mattresses, buckle initiator sleepers and active pipe supports, in addition to span correction, and conducting flooding, cleaning, gauging and hydro testing of all pipelines.
