Risk assessment due to collision between platform PHE-7 and passing vessels

PHE is going to develop seven offshore platforms, one of the platform (PHE-7) is located at particular position that is considered close to access channel to several ports and other under development ports. Considering the mentioned development, a risk assessment study is necessary to ensure that the development would not cause any risk to current marine traffic as well as future traffic. The risk considered here is the collision between platform PHE-7 with vessels operated in that area. This study is aimed to perform risk assessment due to collision between platform PHE-7 and ships and to recommend mitigation should the risk is unacceptable. Three types of collision were developed here were head-on (powered passing vessel) collision, drifting vessel collusion, and visiting vessel collision. Each type of collision was then assessed using three main scenarios: by maintaining position of Buoy No.1 and Buoy No.3, by shifting position of Buoy No. 1 and Buoy No.3 (to align with the position of MPMT) and by combining those two scenarios. The collision risk assessment found that risk due to collision vessel-platform is in acceptable condition.
