CLIENTS + PARTNERS

A fast-growing company, Anakata works with leading wind farm owners, asset managers and wind turbine manufacturers to improve their commercial performance. This commercial success includes significant projects such as:

  • Upgrade packs on a range of turbines, the oldest of which has been operating since 2016 and the biggest of which to date is on a 7MW turbine with no parts failures.
  • Upgrade packs successfully installed on over 20 different turbine technologies and models including Vestas, Siemens, Nordex, Gamesa, GE, Dongfang and Mingyang, both onshore and offshore.
  • Anakata InfraRed audit service provides an aerodynamic audit of operational turbines. Audits are done with the turbines spinning, ensuring no need for technicians to stop the turbines and no lost production. The audits include an identification of performance loss in MWh from blade erosion and how much power can be regained from remedial actions. This enables a proper cost benefit analysis for O&M blade operations.
  • Noise remedial solutions. Using our aerodynamic experience, detailed knowledge of blade designs and site assessment tools, Anakata have worked with wind farm owners to help overcome concerns over noise emissions. Anakata have developed specific noise remedial parts that can help reduce noise emissions from blades and overcome complex noise problems like amplitude remediation. We have also designed and installed metallic Tip Boosters to provide far better control of airflow over blade tips to help reduce noise sources, improve the LPS of the blade, and also some additional AEP.
  • Our Anti-Soiling & Icing Blade Conditioning Wax, designed to help prevent blade soiling or ice formation on the blade that can lead to significant turbine curtailment and poor aerodynamic performance.

NADARA

NADARA

Our work has included a significant engagement with Nadara, which operates wind farms in 11 countries with 3.9 GW installed capacity. Nadara set us the challenge to see how we could increase the AEP at two of its largest wind farms in Scotland whilst operating within the design parameters of the turbines. Initially, upgrade trials were completed on four turbines, with turbine mounted LIDARs installed to provide high accuracy wind measurement and facilitate power performance validation of the upgrades.

 

Nadara’s detailed validation concluded that the upgrade packs were resulting in the capture of an additional 5% AEP. As a direct result of this impressive achievement, Nadara went on to install upgrade packs on all 61 turbines across the two wind farms. Since then the collaboration has continued across numerous countries and turbine technologies, providing industry leading solutions that deliver significant additional clean energy.

 

So, if you’re an organisation running a successful wind farm, want to maximise output and uplift your AEP, or you’re a manufacturer of equipment for the wind sector and you’d like to hear more about the Anakata approach towards optimising wind turbine performance, please get in touch.

SATIP

The SATIP has been developed with support from the Offshore Wind Growth Partnership. The two year development programme involved significant research and development, wind tunnel prototype testing together with detailed testing of specific features including rain erosion testing of leading edge features, and lightning protection system tests to develop and validate the final design.

The programme has also included Anakata installing their own blade tip fatigue rig, designed to measure and validate blade fatigue loads and the benefits the SATIP can bring to reducing unsteady fatigue loads on blades. The first offshore installation of the SATIP Tip Booster was completed in 2024.

Anakata have also worked with the Offshore Renewable Energy (ORE) Catapult’s Marine Energy Engineering Centre of Excellence (MEECE) to demonstrate the performance improvements from Anakata’s Vortex Entrainers and validate CFD modelling as a tool for accurately predicting the impact of performance upgrades. As part of the collaboration research project UK consultants Natural Power performed an independent comparative performance assessment.

Nacelle mounted LiDAR was installed as part of the project to help derive turbine power curves pre and post installation of Anakata’s Vortex Entrainers and Lift Tabs. The assessment by Natural Power used data corrected for lidar induction, air density corrections and SCADA density corrections, and using industry standards concluded that the upgrade parts achieved a 5.7% increase in AEP.
