The wind industry is set to benefit from the latest technology in ultrasonic measurement systems thanks to a new partnership between bolt tensioner experts TensionPro and EchoBolt, the leading provider of fastener inspection services. 

Together, the two companies can deliver an end-to-end solution for joint integrity management which combines experienced connection design support, superior tensioning products, advanced inspection technologies and through life asset integrity management, all in a single joined-up solution for wind farm operators. 

The TensionPro SONAR ultrasonic measurement system is a market leading system for measuring bolt loads. EchoBolt has based their advanced bolting measurement methodology, procedures and data management systems around the SONAR platform to deliver best practice integrity management solutions for critical wind turbine bolted joints. 

Explained TensionPro Director Dave Metzger: “With our duo range of bolt tensioners we can tighten bolts and with our SONAR system we can measure and check the bolt loads. Now, with EchoBolt’s vast experience and service offering, we can ensure that our customers have best practice management of the bolt load verification process and management of the data for process improvement and long term asset integrity.” 

Added EchoBolt Director Peter Andrews: “Management of structurally critical fasteners represents the single biggest scheduled service activity on wind farms and one of the most challenging health and safety risks to service technicians. With many years hands-on experience of bolt load verification of wind turbines, we believe the SONAR measurement system is the standout solution to manage bolted joint integrity and can be successfully deployed to eliminate risk, reduce costs and increase production. 

“Our philosophy of ‘right first time’ assembly followed by long-term condition monitoring is perfectly complimented by TensionPro’s excellent duo tensioners and SONAR measurement system. This is an ideal strategic partnership for us.”
