Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways against wave and ice action has to be provided to safeguard the drilling and production equipment and people on islands. Extensive research and development work has been conducted to derive the optimum protection measures. It is imperative to incorporate the Contractor's experience into this R&D effort, since the construction and installation of slope protection is one of the most important factors for achieving a cost effective project. A state-of-the-art review of various protective measures is presented from a contractor's point of view and is concluded with the Contractor's expectation and recommendations for the slope protection of Arctic islands in the future.
