abstract
A high level strategic problem faced by regulatory agencies as well as commercial shippers is that of the evaluation of the merits of various alternative policies for transportation of crude oil and petroleum products taking into account both transportation and risk costs. A novel risk estimation and assignment methodology is presented. Based on historical oil spills, using causal data, risk costs are assessed for the bodies of water where shipping lanes and routes lie. The methodology determines risk cost estimates between two points of reference for the various products being transported by a variety of vessels being used. The maritime oil transportation problem has been formulated as a multiobjective, multicommodity, multiple origin-destination, and a multimodal problem. The two objectives being considered are the minimization of transportation and risk costs. The application of the developed methodology on a real-world case study for the Gulf of Mexico is elucidated. This is an abstract of a paper presented at the 28th Arctic and Marine Oil Spill Program Technical Seminar (Calgary, Alberta 6/7-9/2005).
