Effects of impacts from large supply vessels on jacket structures

Abstract

The primary function of a jacket structure is to support the weight of the topside structure by the weight to the foundation. In addition, the jacket structure must also be designed to resist accidental loads, such as boat impact. This thesis presents the result from high energy ship collision on a jacket structure. There will be four jacket structures that shall be subjected to high energy impact to see the effects it have on the structures. To date, few researches have been carried out on vessel-to-jacket collisions. This thesis implements the basic design principles of ship collision and several reasonable assumptions. It is expected that the results could provide an overview of how the different potential impact locations and directions will influence the resistance capacity of the jackets. It is also anticipated that this procedure and the assumptions could be a reference for related research in the future.
