Omega Morgan, one of the West Coast’s leading heavy equipment transport companies, offered free moving and installation services today for a prototype smaller, lighter, gearless wind turbine and four towers from the Portland area to the Port of Arlington, Oregon.

Harry Lee, developer of the new product and Genesis Wind Inc.’s CEO, said his turbine is a prototype for linear, reciprocating direct-drive technology, a brand new development in the world of wind power. The gearless turbine is valuable to future customers because turbine gears typically wear out quickly, causing great expense and downtime problems, Lee noted. It also is 100 feet shorter than the average 300-foot-tall tower and will weigh 35,000 pounds versus 85,000 pounds for the typical wind turbine and tower.

The turbine, which is scalable to 1.5 megawatts of energy, is the first to be installed by Genesis at a pilot wind farm east of Portland.

Lee said. “I am so excited that this big idea is finally being launched.” He has been working on development of the 25-kilowatt wind turbine since 2009. In the near future, the scaled-down turbines will be used for businesses, government buildings, schools, and countless other places to reduce costs and provide a cleaner form of energy.

“This company has a great future. We want to support local start-ups like Genesis because new local companies mean new jobs in Oregon. Our crews are well suited for this effort and can efficiently pick up the turbine and four towers, move them to the site, and install them precisely as specified,” said John McCalla, CEO and president of Omega Morgan.

He said another Northwest company, Axis Crane, also volunteered its services to hoist the equipment onto two Omega Morgan trailers and to move them into place for the installation. United Rentals, Northwest Portland, donated free rental equipment for the project.

“This is the very first time in 10 years that I have received true, meaningful support for our project,” Lee said. “It means so much to me that these two great companies have stepped forward to help and I am truly grateful.”

Omega Morgan provides services to companies and organizations of all sizes by executing large equipment moves, often in complex environments; moving and installation of semiconductor equipment for the high-tech industry, commercial and export packing, crating and rigging.

Exposure to torsion, oil, abrasion, temperature extremes and human interference can cause downtime and loss of production.

Original equipment manufacturers are required to provide complete systems for industrial applications. Typically, the technical expertise lies in the most critical aspect of the project. Subsequently, many ancillary components are designed to the best of their abilility, but an fall short in the application due to a lack of knowledge and experience in all areas. One example of this is the slipring harness, which controls the three-blade pitch motors. This harness is subject to constant abuse in the form of torsion, oil exposure, abrasion and temperature extremes. When products like these fail, the wind farm experiences significant downtime, loss of revenue, and maintenance expense.

TPC Wire and Cable Corp consulted a major wind farm owner to design and develop a custom slipring harness that addresses the multiple failure modes encountered in the tower. The TPC harness was designed to be flexible at all temperatures, easy to install, and last for many years in the abusive wind tower environment. Previously, the slipring harnesses needed to be replaced every 12 months on average. The TPC slipring harnesses have been in continuous service for more than four years without a single failure.

Snaking the harness through 90 degree elbows, and terminating individual conductors to terminal blocks in very tight clearance areas had previously been very difficult, especially in cold weather. The highly flexible TPC harness was much easier to install at both the hub and the slipring end. Maintenance personnel were thrilled to have a robust, easy to install solution to one of their primary failure areas.

Material and labor cost savings alone totaled $8,575 per turbine, according to the manufacturer, but the increase in production hours of the tower ranged from eight hours to multiple days, depending on the availability of personnel to make the repair. When multiplied across an entire wind farm, the immediate savings and increase in production is important.

Clemson University and its partners in South Carolina is pouring concrete for the first of two foundations that will house the world’s largest wind turbine drivetrain testing stands.

Choate Construction is building the $98 million facility at what is now part of the Clemson University Restoration Institute.The concrete foundation will form the base of the stand that will allow full-scale highly-accelerated testing of advanced drivetrain systems up to 7.5MW with 50Hz and 60Hz capabilities. It is scheduled to be operational in early 2013. The second test stand that will be able to accommodate next generation wind turbine drive trains up to 15MW will begin operation in spring next year.

The US Energy Department in November 2009 awarded a $45 million grant to the Clemson-led group under the American Recovery and Reinvestment Act to help build and operate the project. South Carolina and private donors provided the about $53 million in matching funds.

Clemson’s public partners are the State of South Carolina, South Carolina Commerce Department, South Carolina Public Railways, South Carolina State Ports Authority and the Charleston Naval Complex Redevelopment Authority.

The site is adjacent to existing rail and dockside infrastructure, essential for handling the heavy components.

University officials estimate the drive train testing center will create as many as 800 direct and indirect high-paying professional jobs.

Sandia National Laboratories and its academic and private partners expect to have a state-of-the art wind turbine research facility in operation in October in Lubbock, Texas.

The first phase of Scales Wind Farm Technology Facility (SWIFT) is being constructed in partnership with Texas Tech University in Lubbock, Vestas and Group NIRE, a renewable energy development company.

The US Energy Department’s Office of Energy Efficiency and Renewable Energy is funding Sandia’s work, which will allow the use of the site for research.

Studies at the facility will initially focus on turbine-to-turbine interactions and innovative rotor technologies. Other areas for investigation include aero-acoustics and structural health monitoring of turbines using embedded sensor systems.

The SWIFT concept reflects a shared emphasis among the partners on lowering the cost of wind energy by maximizing the output of a wind farm rather than a single turbine.

The site will initially use three Vestas 300kW V27 turbines, which are smaller than utility-scale turbines. Sandia worked with Vestas to develop the site plan, uniquely tailored to study turbine-to-turbine interactions.

The site might eventually expand to include nine or more wind turbines, allowing researchers to learn how individual turbines and wind farms can integrate better with the grid.

Engineered specifically for polyester or vinylester resin systems, HiPer-tex™ W3030 roving also allows for longer, lighter blades for both offshore and onshore wind turbines.

3B is launching HiPer-tex™ W3030 high performance roving – the third product in the company’s series of innovative solutions for wind turbine rotor blades.

Specifically developed and engineered for polyester and vinylester resin systems and for resin infusion processes, HiPer-tex™ W3030 roving provides yet another novel option which allows OEMs to manufacture longer and lighter blades for the larger multi-megawatt wind turbines located both onshore and offshore.

3B, HiPer-tex™ W3030 rovings combine high performance glass properties and enhanced sizing compatibility with unsaturated polyester and vinylester resin systems. This new roving provides optimum properties for rotor blades created with lower cost resin systems and therefore helps blade manufacturers narrow the gap with higher cost, alternative composite solutions.

The new roving offers up to 10% weight saving for the same design and length when comparing rotor blades manufactured with traditional E-glass. In addition, the turbine blade span can be lengthened by up to 6% while still maintaining the same weight though contributing up to 12% more energy output.

A more consistent laminate quality is achieved as HiPer-tex™ W3030 roving offers better wet-out. Higher shear strength and substantially greater interfibre strength and excellent fatigue performance is provided by the significantly improved resin matrix adhesion when compared with existing high modulus fiberglass in the market place.

3B’s technological expertise and manufacturing know-how delivers reliable, high performance, sustainable and cost-competitive solutions for wind energy applications especially designed for the challenging and bigger multi-megawatt turbine blades, according to the manufacturer.

Other recently launched products in 3B’s rovings products for wind turbine blades include HiPer-tex™ W2020 and SE2020 made with Advantex® glass, both specifically designed and engineered for epoxy resin systems used in resin infusion or prepreg processes.

During the last few months the Evance R9000 small wind turbine has undergone further tests which have confirmed its energy generation has increased by over 4% to 9,167kWh at a wind speed of 5 metres per second.

The R9000 small wind turbine was one of the first small wind turbines to achieve SWCC conditional certification last year, and has received further improvements since.

Many Evance customers have already benefitted from higher than expected energy generation as the R9000 system improvements were implemented several months ago. For example, Clive Breeze was pleasantly surprised with the energy generated from his recent installation: “In the first three weeks alone, the R9000 turbines exceeded the predicted energy generation targets by 10 percent.” This reduced the customer’s first quarterly electricity bill by the equivalent of nearly $500.

“We’re delighted that our R9000 turbine is proving so efficient in energy production as this translates directly into a faster return on investment for our customers,” said Kevin Parslow, CEO of Evance Wind Turbines. “Our R9000 machine accounted for a third of all small wind turbines sold in the UK last year – making it the UK’s small wind turbine of choice. We look forward to accelerating our drive into the North American market though our network of installers in a bid to establish a similar market leadership position,” concludes Kevin.
