Abstract:

An overview is provided of the engineering considerations and approach to deployment of the Molikpaq. Topics addressed include site investigation, foundation preparation, berm construction, caisson set-down, core filling and assessment of as-constructed stability. To reduce the increasing cost of exploring in deeper water, a caisson is used to substantially reduce the fill volume over that of artificial islands, while still retaining sufficient mass to resist large ice loads. The caisson is placed on an underwater berm, which allows the caisson to be used in a range of water depths.
