FacebookTwitterLinkedInEmailPrint分享Recharge:Rare-earth-free permanent magnet generators (PMG) for offshore wind turbines with nameplates of 20MW are expected to be a reality “within three years,” following trials of a new-generation concept at the UK Offshore Renewable Energy (ORE) Catapult facility.A 250kW version of the axial-flux design being developed by GreenSpur Wind, which uses ferrites – an iron-rich ceramic – for its magnets, would be part of a four-module 1MW unit that is foreseen to be scalable to a power rating roughly twice that of the biggest PMGs in service today.“It was our intention from the outset to design a generator that could be scaled for the next generation of offshore wind turbines,” said Hugh-Peter Kelly, GreenSpur’s head of technology and the inventors of the design. “The feedback that we’ve received is that current designs have known limitations and new concepts will be needed to deliver next generation 20MW offshore wind turbines.”GreenSpur is now moving forward with modelling for “significantly bigger, multi-megawatt generators”, with the target of designing a 12MW-plus concept for offshore turbine created by “stacking” three 4MW units in parallel.Replacing high-price rare-earth materials with ferrites – a waste material produced in steel-making – would cut the cost of PMG magnets from £40/kg ($50/kg) to around £1/kg, according to GreenSpur calculations, meaning the design could carve around 33% out of the capital cost of direct-drive generator, and so almost 5% off the price of a turbine.More: Offshore wind turbine 20MW generator ready ‘within three years’ U.K. company sees potential for 20MW offshore wind turbine within three years

The United States Tuesday announced that it will conduct subject matter expert exchanges with the Trinidad and Tobago Coast Guard later this month.It said the August 9-22 exercises will include diving and medical care exercises designed to enhance coordination in regional maritime activities and improve the operational readiness and interoperability of participants.As a result, the USS Gunston Hall (LSD 44) will arrive here on Wednesday for a three-day visit in support of U.S. 4th Fleet’s two concurrent deployments, Southern Seas and Southern Partnership Station.The ship was deployed by the U.S. Navy last month to the Caribbean, Central and South America to conduct subject matter expert exchanges (SMEE), key leader engagements (KLE) and serve as the 2018 flagship for one of the largest annual maritime training exercises in the world, UNITAS.“The SMEE is a demonstration of the continued, steadfast partnership between the U.S. and Trinidad and Tobago, which is characterized by trust and respect and based on our shared democratic values,” said U.S. Embassy Chargé d’Affaires John McIntyre.Washington said that the Southern Partnership Station is an annual deployment focused on exchanges with regional partner nation militaries and security forces.It said this year’s deployment will visit Trinidad and Tobago, Colombia, Honduras, Panama and El Salvador to work alongside those nations’ military forces, security forces, civilian health professionals and other governmental agencies.In addition to SMEEs and KLEs, for the first time in the U.S. Southern Command area of responsibility, the Southern Seas deployment has integrated a multinational staff as part of continued efforts to improve regional response to natural disasters and security threats, the US said.
