Abstract:

This work examines the capability-models of ships performing counter-piracy patrols in the International Recommended Transit Corridor, located in Gulf of Aden GOA. Specifically, it considers possible approaches to predict the response time of assets patrolling long and thin regions and to facilitate coordination between multiple assets. For situations where the pirate attacks occur randomly, the across-channel location of the ship prior to the attack has only a limited impact on the response-time probability distribution, supporting the notion that the problem can be examined in a one-dimensional 1D context. It is demonstrated that the 1D approach is extremely effective at reproducing the cumulative distributions of higher fidelity models. The 1D approach is then used to demonstrate that coordinating patrol ship positions is a key factor, while coordinating the rotation of helicopter crews between ships may be less important. It is also shown that for the types of wind fields in which pirates will operate in the GOA, a ship can reposition itself in a manner such that the winds will not heavily affect response capabilities. Finally, a description of how the results from this work can be applied in the development of an asset positioning model are presented, and a description of the way forward is provided.
