Ardent have recently completed the final decommissioning of a drilling island in the Beaufort Sea, NW Canada for a major oil company. The project was another successful delivery from Ardent in a hostile and challenging environment, on a day rate basis, coming in under budget, ahead of schedule, no environmental impact and zero LTI’s. 

The Tarsiut Island, in the Yukon territory, consisting of reinforced concrete caissons, was installed in the 80’s as an artificial drilling pad and designed to withstand the harsh arctic environment. The decommissioning has taken several expeditions to complete and the final element was the refloating of the caissons and load onto a heavy lift vessel for onward transport to the disposal yard.

Ardent undertook the pre-engineering and execution of the project including site clearance. Detailed and dynamic planning with the client and supply chain was undertaken to take account of the ice and inclement weather. Several surveys were required to plan the logistical elements of the project as the equipment and services were required to be trucked on the challenging road to and from Inuvik. To mitigate the risks involved in shipping kit from Ardent’s Houston facilities, establishing localized supply chain became imperative with the added benefit of providing work and revenue for local communities. Seven truckloads of salvage equipment, the mooring spread, high performance pumps and diving equipment made their way across country to enable the project.

Robert Wesselink, Project Manager was quoted as saying the key to the project being positively delivered was; “open, direct communications with the Operators project lead and the dedication and experience of Ardent’s versatile offshore team”

Ardent Sales & Marketing Director, Stuart Martin went on to add that; “the project ably demonstrated again that Ardent does decom differently from others. Using the world’s tool box to match asset to task and deploy an innovative use of commercial arrangements gives us the distinctive competencies required to take on large scale and testing decom projects, globally“.
