HAI-TECH Project

HAI-TECH - Low-Friction Surfaces Due to Innovative Coatings

Duration: September 2008
– August 2011

Project consortium:

  • Fraunhofer Institute for Manufacturing Technology and Advanced Materials

  • Hamburgische Schiffbau-Versuchsanstalt GmbH

  • TKMS Blohm + Voss Nordseewerke GmbH

  • Beluga Shipping GbmH

  • Fahrion Produktionssysteme GmbH & Co. KG

  • Laboratory for Freshwater and Marine Research - LimnoMar

Strategic objectives addressed:

  • development of a ship hull coating with a sharkskin structure

  • significant reduction of fuel consumption of ships due to low resistance

  • reduction of atmospheric emissions of greenhouse and acidic rain gases

Project abstract:
The scope of the project is to reduce the residual friction of the ship hull by the development and application of an underwater coating with a riblet surface. This structured surface shall save fuel and reduce emissions of greenhouse gases, thus fighting the climate change. In the first phase of the project trials with ship models corroborated the friction reduction by a sophisticated arrangement of the riblets. In the next phase of the project the development of an automated device for the application of the the riblet coating in the dockyard is a main milestone. In parallel, formulation and testing of appropriate and effective fouling prevention systems are going on in simulated field tests. The riblet structure has to be enhanced by an inherent antifouling property to maintain the surface structure and to avoid the loss of efficacy by fouling. In 2009 exposure trials in seawater on coupons and plates are going with 16 biocide-free antifouling systems. In the next years the most prospective sytems will be tested in field condition. Beginning with test patches the project hopefully ends up with a full hull coating system.
