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.

EchoBolt was recently engaged by SSE Renewables during a pitch bearing replacement campaign to measure bolt preload in the outgoing blade connections to provide insight into bolt preload. On the reassembly, bolt preload measurement has been used to ensure high quality joint assembly eliminating the risk of maintenance induced failures.
