CleanShip industry solution for prevention and detection of fouling on shipsTWI Ltd (The Welding Institute)190, Great Abington, Cambridge, United Kingdom
CleanShip Consortium with the SS Rotterdam, Holland. The Brunel Innovation Centre (BIC), a research centre operating as a long-term strategic partnership with TWI Ltd, has recently completed a two year pan-European collaborative project, funded by the EC, to develop an effective, non-invasive and novel solution for prevention and detection of fouling on ships.
The marine industry spends billions of pounds globally to address the issues and challenges associated with fouling, using a variety of protection methods such as coatings and cleaning tools. Six months without protection against marine fouling deposits can lead to increased drag on the hull so much so that a ship may use up to 40% more fuel and produce 40% more CO2 emissions.
CleanShip had the following objectives:
The CleanShip system developed important advantages:
Field trial successesIn the initial stages of the project, trials for biofouling prevention on steel plates, both provided by Enkon (Turkey) and WRS Marine (Holland), with transducers from Sofchem (France) characterised by BIC, were carried out in a real port environment in Holland.
Single and multichannel generators, including the Teletest® long-range guide wave ultrasonic test system, were experimented with for inducing ultrasonic waves on plates for the duration of the trial, which lasted approximately 45 days. Following feedback from the initial field trials, the CleanShip consortium went on to further validation through field trials for longer duration (over three months) in Holland, where the CleanShip project has come to a successful conclusion. The new technology has been well received by the industry.
