INDUSTRY UPDATE The vertical Pulsus prototype tidal energy turbine.


TIDAL TURBINE SUCCESSFULLY TESTED

James Brodie, Director of Energy at CBBC added: “With the inclusion of marine energy in China’s 13th Five Year Plan, and ambitious targets, it’s an emerging sector that the country would clearly like to see developed rapidly but significant gaps remain in their innovation infrastructure to make this a reality. As the world leader in marine energy, the UK is in a fantastic position to support and benefit from this development by engaging at an early but crucial stage.”


THIRD WORKSHOP


A third workshop focusing on wider commercial dialogue between the UK marine energy supply chain and China will take place between 15th-17th February 2017, and companies are invited to register interest.


EMEC


Vesconite Bearings is proud to be associated with tidal energy equipment developer Norwegian Ocean Power, which has successfully trialled its Pulsus horizontal-axis spiral-design tidal turbine, as part of the development of its first commercial unit.


TESTING


The turbines were tested in Drammensfjorden, Norway, where a dynamic test on the composite structure and bearings was performed. The structure bends and flexes with tidal currents, which can produce significant turbulence and considerable upward and sideward forces, so the testing of uneven forces is a key part of testing for this tidal-turbine. “We were hoping to separate out any vibration from the structure,” commented Technical Director and founder Kent Thoresen, noting that the company’s turbine was successful in this aim. The thrust bearings moved backwards and forwards and eliminated the vibration as planned, that may have otherwise lead to a systemic failure.


BEARING SELECTION


The 0,5m-diameter Vesconite bearings, meanwhile, which were installed on each end of the horizontal unit, also performed

well in their ability to absorb vibration. They were chosen after the testing of various competing products that were less flexible and exhibited dry-run problems. They are also shown to exhibit no swell in water; require no grease, oil or additional lubrication; and have a load capacity that is unaffected by water.


“There are many failed projects in the tidal energy industry due to turbulence that causes vibration and uneven force distribution. That is why it was important to fully test our unit in real sea conditions,” Kent concluded.


NORWEGIAN OCEAN POWER


Norwegian Ocean Power is the owner, financer and developer of the innovative turbine technology, which will be installed in the sea of Norway next year and begin commercial production of 1TWh of energy per year for use in Norway. The intention is to start production on several turbines in 2017 and 2018, with Canada and the UK being the most likely first markets for these turbines.
