Featured Projects
01
Customer Self Perform - BoltWave
BoltWave has been designed as an intuitive bolt inspection tool allowing customers to easily adopt the technology. Equinor is the first customer to implement the technology across their offshore wind fleet.
01
Managing a fleet of wind assets - BoltWatch
EchoBolt's BoltWatch platform has been successfully implemented by RWE across five offshore wind assets in the UK and Germany.
01
Blade bearing exchange - Bolt management
A significant part of replacing wind turbine drive train components is ensuring high quality, efficient tightening of critical bolted connections.
01
Wind Farm Life Extension - Structural Inspections
As wind assets approach design life, the opportunity to continue safe and efficient operation is a key value lever for wind turbine operators.
01
Offshore Foundation Bolted Connections - Condition Monitoring
EchoBolt has supported RWE with a long-term monitoring and inspection campaign for offshore wind monopile foundations.
01
Wind Turbine Tower Connections - Preload Assessment
In partnership with GE Renewable Energy and ORE Catapult we have completed the assessment of bolt preloads in wind turbine tower connections to help eliminate hydraulic check-tightening
01
Blade Stud Failures - Assessment and Investigation
Wind turbine blade connections are notoriously challenging to manage with regular integrity problems and difficult maintenance access.
01
Phased array inspection of industrial bolt defects
Large, bolted connections across industries may be subject to fatigue and ultimate failure. Phased array ultrasonics is state of the art technology for non-destructive defect investigation of these bolts.
01
Identifying Bolt Defects - Phased Array Inspection
Phased array ultrasonics is a game-changer for bolt inspection, especially in the wind turbine industry. This cutting-edge technology allows for faster, more accurate, and more efficient inspection of bolts, making it an essential tool for integrity management in the wind energy sector.

Nextera Energy - Transatlantic bolt technology
01
Setting New Records - Rock Anchor Foundations
Need a ten meter bolt measuring? No problem.

Low cost, repeatable measurement
Delivering a range of proprietary inspection methodologies our team is able to efficiently monitoring existing preload in bolted connections. Eliminating the need for routine retightening on wind turbines providing substantial cost savings and significant health and safety benefits.

Techncial training
Customers can follow our dedicated wind turbine bolt inspection syllabus or we can work with you to design bespoke solutions focused around your application specifics.
Increased speed & efficiency
Requiring less than 10 seconds per bolt to carry out each measurement allows a single technician to inspect thousands of bolt per day. With no permanent hardware installed and no requirement to loosen or retighten fasteners, EchoBolt inspection provide an extremely cost effective method to generate high quality condition assessment of bolted connections.
