Abstract:

At offshore lease sites located along the western coast of Alaska, longer periods of open water can be expected. As a result, wave induced hydrodynamic loading will become a more significant design consideration. It is anticipated that conventional deep water platform designs fitted with ice-breaking cones can be used at these sites. A combined analytical and experimental investigation into the dynamic response prediction of a monotower platform fitted with an ice-breaking cone was recently conducted. The case of a monotower platform fitted with a 45 degree cone is presented and discussed.
