2017 Tarsiut Caissons Arctic Decommissioning Project
The Tarsiut Caissons Arctic Decommissioning Project involved refloating and removing four 5,000 tonne, 70m long concrete structures from the Beaufort Sea, near Herschel Island where they had been stored since 1984. The four caissons were originally used to form an artificial island from which two exploration wells were drilled in the early 1980s.
The extremely complex project, executed in the summer of 2017, had numerous challenges including a high regional profile; stringent and varied regulatory requirements; a remote location in a delicate environment; multiple, narrow operating windows and limited local services.
Global resources were required to plan and execute this project using international personnel, services and equipment.
The project team developed processes and learned significant lessons as it moved successfully through the planning, contractual and operational phases of the project.
The presentation will walk through a selection of the challenges, the processes used, the execution and some of the lessons learned which allowed the team to successfully complete their objective.
