First-year ridge interaction with the Molikpaq in the Beaufort Sea
This paper presents details of the failure behaviour and loads associated with the interaction of first-year ridges with the offshore structure Molikpaq. An analysis was made of ridge interactions during 2 years of deployment of the Molikpaq in the Canadian Beaufort Sea. The first-year ridge interac...

This paper presents details of the failure behaviour and loads associated with the interaction of first-year ridges with the offshore structure Molikpaq.

Typical ridge failure modes included spine failures, failing behind the ridge, shearing, stopping and mixed modal.
