During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today’s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions. The model takes intoaccount the ship’s loading condition, winds, wind waves and swell. Any othereffects are pooled in one term. This makes it possible to also consider how muchfuel the ship consumes on the various route options in the planning process.The model will also be a useful tool to retrospectively evaluate how a ship hasperformed in relation to the contract.On the ships in this report the prediction program was able to calculate thefuel consumption with an error of only 1% of the reported fuel consumption.This requires that the data about the vessel is accurate and up to date. If not,the model can still, with thoughtful assumptions, reach an error of less than10% of the reported consumption, which is better than the strategy that SMHIuses today.
