    Dynamic Positioning of Tugboats

    • Johan Oppen, prés., Molde University College
    • Brice Assimizele, Aalesund University College
    • Johannes O Royset, Naval Postgraduate School

    The Norwegian Coastal Administration monitors vessel traffic along the Norwegian coastline and uses tugboats to prevent drifting vessels from running ashore. We present a model and a solution approach for dynamic tugboat positioning aimed at minimizing the expected costs of grounding accidents.

  • 15h55 - 16h20

    Speed Optimization in Supply Vessel Planning under Weather Uncertainty

    • Ellen Karoline Norlund, prés., Molde University College
    • Irina Gribkovskaia, Molde University College

    The oil and gas industry relies on careful planning of supply vessel operations for delivery of cargo to offshore installations. We present speed optimization strategies for the generation of environmental friendly supply vessel weekly schedules and evaluate the performance of the strategies with discrete-event simulation taking weather uncertainty into account.

  • 16h20 - 16h45

    An Exact Method for Routing and Scheduling of Roll-On Roll-Off vessels

    • Jørgen G. Rakke, prés., Norwegian University of Science and Technology
    • Guy Desaulniers, GERAD - Polytechnique Montréal
    • Magnus Stålhane, Norwegian University of Science and Technology

    We present a branch-and-price method for routing and scheduling of Roll-on Roll-off vessels used to transport multiple commodities. The method is based on a hybrid nested column generation approach where we pre-generate paths and dynamically generate the schedules and pickup quantities for each vessel-path combination.
