Abstract
Improved coordination between shipping lines and terminals through speed optimization is a candidate measure to reduce fuel emissions in the international shipping industry, according to the International Maritime Organization. To quantify the potential benefits of this instrument, we integrate speed optimization in the berth allocation problem in a dynamic, rolling-horizon setting. Before our simulation runs, we determine a tactical-level baseline schedule, in which each vessel is assigned a time slot and berthing location. We propose two variants of speed optimization: one where the baseline order of service and berthing locations are unchangeable and one where they can be changed. If speeds can be adjusted during the last 1,500 nautical miles of sailing, we find that speed optimization can result in a 4% to 6% reduction in total cost. However, while deadline violation cost is reduced, fuel usage increases. Besides quantifying the benefits, we introduce a system of penalties and compensation through which the cost savings are distributed fairly across vessels and which ensures that both the terminal and ships profit.
