David Pisinger: Challenges in modern tour planning on a selected case study

Fuel purchasing in liner shipping with new sulphur emission control areas


Co-Authors: Christian Plum, Peter Neergaard

DTU Management Engineering



Since January 2015, all vessels in the Emission Controlled Area (ECA) of the Baltic Sea, North Sea, English Channel and waters 200 nautical miles from the coast of US and Canada, have had to reduce their sulphur emissions to 0.1%. Vessels are required to use either a distillate, an alternate fuel or install a scrubber that removes sulphur from the exhaust after combustion.

In this talk we present a decision support tool for fuel purchasing, making it possible for a liner shipping company to fulfill the emission regulations at minimal expenses. The decision support tool makes use of the fact that fuel prices vary from port to port, and also vary over time. Hence the task is to purchase the right quantities at the right port during a round trip.

After presenting the problem in details, we start with the simple case of one vessel, and then extend it to a whole fleet of vessels, making use of shared constracts.

The talk will end with outlining the parallels with land-based transportation – especially challenges arising with the integration of e-mobility in tour planning as addressed in the flagship project SEAMLESS.
