Increased energy efficiency in ships through reduced hull fouling
Research Project, 2015
– 2017
The energy and bunker consumption in a ship is dependent on several factors. Condition of the ship hull and degree of marine growth (biofouling) on the hull is an important factor. A hull with biofouling requires 15-20% more power for propulsion than a newly painted or maintained hull. Ship hulls are cleaned with brushes inbetween painting but the optimal frequency and forces needed for cleaning of the hull have not been investigated. The aim of this project is therefore to optimize the method for in water hull cleaning. Through pro-active brushing of the first stages of marine growth, there is great potential to avoid further biofouling and increased friction. With less biofouling on the ships the energy requirements and fuel consumption will decrease which means savings both for economy and the environment.
