RPS is the project lead on Arctic oil and gas decommissioning project in the Canadian Arctic. The work includes the design and execution of a field program with sampling and chemical and biological analysis of material associate with the four 5000 ton caisson structures. The structures were originally built to protect an artificial drilling island and have been resting on the seafloor at a temporary location since abandonment in 1984. The field work was completed in September 2016 and involved a team of seven professionals with equipment mobilized from Canada and the USA. RPS work on the project is ongoing with key deliverables being recommendations on disposal options.
