As part of the development of the EchoBolt technology repeat inspections of bolted tower connections were carried out for ORE Catapult on their Levenmouth Demonstration Turbine.
Average preloads measured were within 4% of the installation targets for the tower connections with all bolts well above the minimum preload threshold eliminating the requirement to retighten the tower joints.

“EchoBolt is set to reduce the need for manual work in a crucial operational area, bringing huge safety and cost benefits.”
Through the successful delivery of annual ultrasonic bolt inspection campaigns, Echobolt has supported RWE in the management of structural integrity of their large offshore wind assets.
Providing comprehensive integrity data via BoltWatch has enabled RWE engineers to have instant visibility of asset health and condition trends for the first time.

“EchoBolt inspection services have been instrumental in assuring asset integrity and eliminating the requirement for excessive bolt retightening.”
