MARIN concluded the seakeeping and manoeuvring model tests for the SMOOTH EU project. This project aims to achieve energy efficiency gains through the application of air bubble lubrication and through advanced coatings. In this technique, air is injected from various locations under the ship in a bid to reduce frictional resistance. Additionally, special coatings are used to improve the effect.
Along with other ongoing research, MARIN performed model tests to determine if this type of air lubrication has an influence on seakeeping and manoeuvring behaviour. Free sailing tests in the Seakeeping & Manoeuvring Basin were conducted with a model that featured a comprehensive air injection system. Results show that air lubrication has minimal effect on manoeuvring and no noticeable effect on seakeeping behaviour. A paper, which also includes results on powering and full-scale tests, was presented at the 2009 SNAME Annual Meeting & Expo (see www.marin.nl for download).
