Defends thesis about reducing the environmental costs from oil tankers accidents

Av: Straumsheim Jens Petter | Publisert: 29.05.2017 10:23:58

​Brice Assimizele holds his trial lecture and defends his PhD-thesis on Monday 12 June. The title of the thesis is “Models and algorithms for optimal dynamic allocation of patrol tugs to oil tankers along the northern Norwegian coast”.  His trial lecture starts at 10.15 in Auditorium A-112 with the title “Empty container repositioning”.

​Marine transportation of crude oil and petroleum products and its associated risk to the environment have increased significantly during the last decades. To safeguard the marine environment from potential oil spills and other damage from grounding of vessels, the Norwegian Coastal Administration (NCA) operates a center for vessel traffic service (VTS) in the town of Vardø in northeastern Norway.

The PhD research is conducted in close collaboration with the NCA, where the primary objective is to develop models and algorithms that optimally reduce the environmental costs from oil tankers grounding accidents. This includes optimal positioning of patrol tugs in a highly dynamic and stochastic environment. We propose a flexible and efficient decision support tool to the operators at the VTS, validated with historical events, that significantly reduce environmental risk associated with drifting vessels.

The methodological approach in this research could be applied to other search and rescue or emergency response related problems.

Brice Assimizele (30) comes from Cameroon. He holds a Bachelor's degree in Computer Science at the University of Yaounde I, Cameroon from 2007, a Master of Science degree in supply chain management at UCSI University, Malaysia from 2010 and a Master of Science degree in Industrial Logistics, Specialization in Operations Research at Molde University College in 2012.
The study was funded by The Norwegian Research Council and NTNU Ålesund.
