Our provision of precise preventive maintenance tailored to our client’s needs such as:
- Purge/flush/replenish bearing lubricants (blade bearing/main bearings/generator bearings/yaw bearings)
- Seal re-conditioning (blade bearings/main bearings/gearbox)
- Electrically insulated bearing installation (generators)
- Re-termination cable repair (generators)
- Yaw gearing lubricant removal/replenish
- Yaw PETP bearing exchange
- Transmission exchange/lubrication
- Desiccant breather installation (gearbox)
- Oil exchange (gearbox/hydraulic)
- Torque/re-tension bolt/joints (tower/hub/blade bearings/blade)

Reduces maintenance (planned and unplanned).
Boosts productivity
Reduces unplanned downtime and optimize production
Reduce dangerous malfunctions
What Our
Clients Say
Since 2018, George and the team at GEOX has provided technically sound and cost effect inspection services to 30 aging Vestas V4X turbines that are Asset Managed by BVG Associates (BVGA). As part of supporting the owners’ journey to life-extend these assets, we engaged GEOX to carry out walk down inspections as well as more detailed drive train condition analysis. Those inspections helped inform plans and associated budgets for ongoing proactive inspections and component replacements necessary to continue operating the assets beyond 20 years. GEOX continue to provide a cost-effective proactive inspection service as well as where necessary reactive inspections and repairs.
In addition, we trust GEOX to be an independent set of eyes and ears to monitor the quality of service provided by the incumbent O&M provider. Only once in the last five years have we had to go to an alternative supplier for inspection services. GEOX continue to be our “go to” for inspection services and associated technical wisdom.
BVG Associates
GEOX Engineering has performed several works for ScottishPower Renewables including multi-faceted drivetrain and blade bearing inspection & analyses. Their work had always been delivered to a high standard and has provided valuable insights into wind turbine component conditions which have subsequently helped inform our operational and maintenance decisions.
Senior Mechanical Engineer
GEOX Engineering completed a comprehensive analysis and independent gearbox inspection on a 30T critical plant crane for one of our important customers. George and the team not only provided a highly professional job but also a 3-step solution for the customer. GEOX provided quality evidence and verification to support target safety levels for extended operation of the crane could no longer be maintained. Would highly recommend to companies needing market leading independent critical plant inspections.
