in severe offshore environments. This made Intersleek the perfect foul release system for the job” said Daniel Christ of Voith Hydro Ocean Current Technologies. This large tidal power device uses a simple


yet robust system to drive the production of power. To reduce complexity, the technology used within the turbine is innovative, removing the need for lubrication of bearings; sea water is used instead. This is a new technological innovation, recently adopted by Voith Hydro Ocean Current Technologies, which is designed to be not only kinder to the environment than typical oil bearing lubrication, but also results in a reduced need for maintenance. Other advantages of the simple turbine


solution include an adjustable rotor; which ensures optimal energy extraction. The turbine is also capable of being mounted onto a range of different foundations. The expectation from those involved in the


project is that just one single turbine from the Voith HyTIDE Tidal Power Plant, which has a


nameplate capacity of 1.8MW will be capable of supplying upwards of 330MW/h energy annually (with a 50% conversion efficiency). Then consider the prospect of an array of


hundreds of these turbines going into service in the not too distant future and you will have an idea of the potential that is yet to be unleashed. “For such a large-scale project, corrosion


protection as well as a high performance foul release was needed to protect the tidal power plant from the severe surrounding environment” stated Andreas Hoyer, Sales Manager for Germany at International Paint. Alongside Intersleek 970 and Intersleek 737,

a system consisting of International Paint’s InterzincR 52, InterlineR 975 and IntershieldR 300 was used. This system was favoured by those involved due to it being approved by the German Institute of Water Steelwork, for its excellent abrasion resistance and its proven track record for use in similar severe, offshore environments. Following completion of coating application and quality approval, the turbine is to be installed and will be in active service over the next two years. It wasn’t just the outstanding proven track


record of International Paint’s protective coatings systems that impressed those at Voith Hydro Ocean Current Technologies, they were also impressed by the testing of its foul release system that International Paint carried out alongside an acclaimed German university. The potential of pursuing wave and tidal


power as a long term source of renewable energy is huge, with the capability of providing 16% of the world’s energy needs. The industry also promises to continue to grow and develop new and exciting methods of harnessing tidal energy over coming years. It’s proving to be an exciting time for tidal power generation.
