Tiivistelmä
The cruise ship leisure industry attracts thousands of customers every year. Furthermore, the increased interest, popularity, and public awareness of environmental sustainability have brought up significant responsibilities to cruising. The consumption of fuel and related exhaust gas emissions has become a relevant subject, impacting the customer's decision-making soon. Consequently, it is significant to improve and diminish energy consumption.
The thesis examines the reduction of fuel consumption by improving itinerary planning and base it on the vessel's optimal speed. To achieve the objective, actual voyages are explored to demonstrate the fuel economy of route profiles. The study also raises a debate on a topic where future route planning could be changed based on the results of the ship's optimal speed. The primary data analysis was based on data collected from the author's work on the Seabourn Ovation in 2018 and 2019 and historical AIS data. The additional information resulted from the author's observation of the participants and through the action research.
In conclusion, for a better fuel economy to follow the average required speed as closely as practically possible, This would give nearly 10% fuel saving for the propulsion consumption at sea without additional investment. Present voyage reporting has shown to be inaccurate and needs improvement. Additionally, the voyage reporting content should be revised to serve the ship's most economical operation better. There is a great potential for emission reduction and fuel saving by taking economical speed into consideration in itinerary planning. Reducing one knot of annual itinerary speed would save fuel nearly 1000MT annually or 20% of the fuel used for sea passages.
