Drivetrain monitoring leading to more efficient turbines

ORE CatapultThe world's newest offshore wind turbine drivetrain test facility could allow for an improvement in the efficiency of the technology.

GyroMetric partnered with the Offshore Renewable Energy (ORE) Catapult to develop and prove an innovative condition monitoring technology for application in offshore wind. GyroMetric saw an opportunity to transfer their drive shaft monitoring technology and use it to try enhance the efficiency of offshore wind turbine drivetrains.

GyroMetric’s product has been tested during the commissioning of ORE Catapult’s Blyth-based 15MW drive train facility. Installed on ORE Catapult’s 7MW nacelle, the GyroMetric team has collected data as a result of monitoring the bearings, gearbox and couplings.

Working with ORE Catapult’s drivetrain experts, GyroMetric’s technology has been tested to improve the understanding of the behaviour of the components in use, with a view to increasing the efficiency and output of the turbine, whilst reducing the requirement for unplanned maintenance. Since testing started, GyroMetric has also secured a significant investment, helping the company to further grow and develop its technology.

GyroMetric has sought to overcome the challenge that the dynamic torque of rotating devices, such as those found in large-scale wind turbines, is difficult to measure. The company has developed an ‘incremental motion encoder’.

The encoder includes an algorithm to calculate shaft position and torsional twist, helping operators to measure drivetrain efficiency more accurately. In addition, the system can alert turbine operators to faults in the drivetrain.

Chief Executive of GyroMetric David Orton commented: “We are delighted that we have been able to run effectively our new digital monitoring technology collecting data on the 7MW nacelle at ORE Catapult. Improving the operating efficiency of wind turbines and reducing maintenance will enable increased output and reduced energy costs, which is good news for both operators and energy customers.

“The move into monitoring wind turbines is an important strategic decision for Gyrometric Systems, and being able to work with ORE Catapult and using their turbine test facilities has provided us with a seriously useful stepping stone.”


Hyunjoo Lee, ORE Catapult’s Drivetrain knowledge area lead, commented: “GyroMetric’s technology is highly innovative and could bring huge benefits to the offshore wind sector. At the Catapult, our combination of world-leading testing assets and industry expertise means we are uniquely placed to support innovative UK SMEs in transferring technologies from other sectors, which can solve some of the challenges faced by the offshore wind industry. It is critical that we continue to build and support a strong UK supply chain in order to maintain our position as a global leader in offshore wind.”
