Funding from Vinnova SEK 860 000
Project duration January 2011 - August 2014
Status Completed

Purpose and goal

The aim of the project was to study the possibilities to reduce harmful emissions from ships by operating these at extremely low speeds, on the order of 5 to 10 knots. The project investigated mainly the possibilities of converting existing vessels tot extremely low speeds and a ship supposed to be built in 2020. Much of the work was to study how wind can be used to achieve this goal. The result of the study indicated quite clear the advantages and disadvantaged of ultra low steaming.

Results and expected effects

The results of the study showed, as expected, that very low engine power is required to propel a ship at extremely low speeds, but that a more normally installed propulsion power is required to safely navigate in severe weather conditions. For desired speeds around 7 knots it is possible in many cases to propel a ship with only the help of the wind. However, it is economically difficult to justify the installation of windpropulsors due to long pay back time.

Approach and implementation

The entire project was carried out by a large number of partners representing various necessary parts to complete the study: ship owners, classification societies, consultants, universities, etc. The work was divided into different packages in that way that those who had the most knowledge in the area took the responsibility for it. The project had also an advisory board existing mainly of ship owners. Results from the study are presented in numerous reports.
