Title: DIRECT Weather Routing
Authors: Hjorth Simonsen, Martin

Abstract: A significant increase in fuel prices over the past decades and focus on global warming have lead to a large interest in fuel efficiency within shipping. Weather routing represents one increasingly recognised method for reducing fuel consumption, hereby lowering emissions. Determining the speeds and route for a ship requires a balancing of multiple objectives including cost, time of arrival, and ship and cargo safety. This calls for advanced multi-objective optimisation algorithms to be implemented. This thesis presents the theory behind weather routing and a state-of-the-art study on available software and research. It also aims at providing the reader with a basic understanding of what elements make up a weather routing tool and what is expected of a state-of-the-art routing tool. In this thesis the DIRECT algorithm is used in the construction of a novel weather routing tool. The output from the tool being routes with optimised speed profiles. The constructed routing tool is demonstrated on several simple test cases determining the capabilities of routing around land, avoiding storms by speeding up or slowing down and utilising weather to the advantage of a minimised fuel consumption.
