Business case assessments drive cost effective use of materials in blades for offshore wind energy installations in STRUCTeam’s new wind blade design portfolio.

Developed in association with DNV GL (formerly Garrad Hassan), STRUCTeam’s portfolio enables wind turbine original equipment manufacturers (OEMs) to benefit from turbine performance and operating cost improvements based on proven composites blade solutions and positive business case assessments.

“It has been an exciting time for STRUCTeam’s wind energy team with several successful new product launches,” highlights Engineering Manager Chris Monk. “We delivered a certified blade for onshore turbines that is currently in full production. Building on our team’s extensive experience, we have extended our reference designs into the offshore arena. Our 78.5m hybrid glass-carbon blade (STL-785- C) is tuned for use on 6MW turbines in large Class IIA offshore wind farm developments.”

As part of the work completed on the new STL-785-C blade, STRUCTeam also developed a number of other reference designs and business case assessments that deliver materials usage at the correct technology level for the client’s needs. The key findings and business benefits of the tuned design solutions have been shared with the international wind energy community at the International China Windpower show in Beijing and GoCarbon Fibre conference in Cologne.

“For aerodynamic design and turbine loads assessment of our wind turbine blade portfolio, we partner with DNV GL,” continues Chris. “Our combined offering brings a very strong solution to any wind energy project. We are experts in managing wind turbine blade development projects and delivering composite structural designs; DNV GL is an aerodynamic design and load calculation specialist and when they partner with us we can manage the whole process for our clients to deliver a turnkey solution.”

STRUCTeam is an independent composites engineering consultancy with specific experience and a strong track record of delivering successful, cost-effective and robust blade designs for the wind energy sector. From assessments on specific components to bespoke blade design developments, STRUCTeam delivers a range of services that assist its clients to achieve lowest overall cost of energy.

Chris concludes: “With the addition of the latest designs to our portfolio, the STRUCTeam turbine blade offering now spans power ranges from 2MW to 6MW for on and offshore sectors across a range of wind classes. From the current portfolio of designs, our clients can choose a baseline reference blade for assessment against their turbine requirements. The reference design can then be tuned for optimum performance and the optimal business case.”
