REETEC receives long-term service contract from Frischer Nordwind for preventive rotor blade inspection

12.12.2019 //

  • Frischer Nordwind awards 4-year contract to REETEC for preventive rotor blade inspection for two wind farms

Frischer Nordwind specialises in the management and direct marketing of electricity from wind turbines and biogas. REETEC was contracted for preventive rotor blade inspection for two of their German wind farms – Rodautal and Lange Heide – over a time frame from 2019 to 2022. The service portfolio includes various tasks regarding the monitoring of rotor blades and tower of the wind turbines. In addition, this turnkey package includes data acquisition and evaluation in a detailed report. The REETEC experts then combine the resulting damage analysis with concrete proposals for repair and maintenance measures, which can be carried out directly on site. Years of experience, optimised processes and rapid execution in compliance with highest occupational safety requirements mean reduced downtime for Frischer Nordwind – and thus safeguarding yields.

In general, REETEC's customised monitoring package offers the following services for preventive maintenance of rotor blades:

  • Internal, external and standardised checklists
  • Detailed analysis of blade condition based on HD images
  • Use of state-of-the-art technologies such as CORNIS, RE-VIS (REETEC Vertical Inspection System) and drones
  • Flexible access by rope on site, rotor blade service platform or cherry picker
  • Fully equipped repair workshop in Emden with corresponding logistics and 30,000 m² hall space

For customers this means: reduced production loss and planning reliability due to limited downtime of their wind turbines

"Why did the order go to REETEC? For two years now we have been dealing internally with the possibility of preventive blade inspection, because the rotors are getting bigger and bigger and should be checked regularly and above all professionally. REETEC's expertise has convinced us the most compared to other competitors," says Heiko Hansen, Managing Director of Frischer Nordwind.

Deadline extension for conversion of on-demand night-time marking for wind turbines: REETEC already offers future-proof retrofit packages and complete solutions for Aviation Aid Systems today

14.11.2019 //

  • The deadline for operators of German onshore and offshore wind turbines to equip them with on-demand night-time marking (German: BNK) has been extended to June 30, 2021.

Under the new Energy Collection Act, operators of wind turbines on land and at sea who are obliged to mark obstacles in accordance with the licensing notice were called upon to equip their turbines with a BNK-system as of July 1, 2020. With the current decision of the Federal Network Agency, this deadline has now been extended to June 30, 2021.

As part of its comprehensive aviation aid portfolio, REETEC offers customised solutions for retrofitting wind turbines both for on-demand night-time marking as well as the newly added requirement for equipping them with infrared light. It remains to be seen which radar and transponder systems will establish themselves on the market in the future. Therefore, REETEC has prepared interfaces to currently approved radar systems as well as various transponder systems that are still under development alike. The following detection systems for air vehicles are supported:

  • Active radar systems
  • Passive radar systems
  • Transponder systems

After installation, the connected detection system is selected via the graphical user interface of the control panel. Therefore, the REETEC aviation aid system can already be installed today without hesitation, even if the final detection system is not yet defined: interfaces to new BNK-detection systems or updates can be easily established by means of a software upgrade later on.

As an amendment, the last draft of the AVV-marking (General Administrative Regulation) now also stipulates the use of infrared lights as a supplementary measure:

  • Infrared – Due to its compact design, the currently developed REETEC infrared light can also be retrofitted to older REETEC aviation aid systems with minimal effort.

Since the law affects new and existing plants equally, REETEC's offer includes both retrofit solutions and complete replacement systems. All RE-LED2 aviation aid systems are already prepared for BNK-retrofitting, but older REETEC systems also become BNK-compatible through easy-to-install upgrades to the latest control technology with web-based monitoring and user interface. In addition, REETEC offers turn-key solutions for systems that cannot be retrofitted.

"The one-year deadline extension gives operators some more time to convert their wind turbines to BNK-operation. However, since around 17,500 existing turbines are affected in Germany, an immediate start is urgently recommended today – and REETEC offers the customised solutions to equip turbines on time," says Claus Sejersen, Director Sales and Marketing at REETEC.

REETEC at HUSUM Wind 2019

06.08.2019 //

It's time again: from September 10 - 13, 2019 REETEC presents itself at the HUSUM Wind. Of course we will present our entire onshore and offshore service portfolio, but with a special focus on:

• Operation & Maintenance Services (O&M)
• Major Component Replacement & Repair
• Rotor Blade & Tower Services

Due to current events, however, there is a clear main topic this year: on-demand-night-time marking (German: BNK) for wind turbines according to the new energy collection law as of July 2020. Here REETEC offers comprehensive on-demand-night-time marking solutions for aviation aid systems. It is still uncertain which radar and transponder systems will be preferred or approved by the authorities in the future. As part of the new and further development of our aviation aid portfolio, we have therefore implemented interfaces both to currently approved radar systems as well as transponder systems still under development.

It is estimated that more than 15,000 wind turbines in Germany will have to be converted or retrofitted for BNK-operation by mid-2020. Our experts will present our BNK-solutions at the REETEC stand interactively and "hands-on".

Do you have any questions on this admittedly complex topic? Then we will be happy to advise you. Because delivery bottlenecks are foreseeable due to the short conversion time, take advantage of HUSUM Wind and our expertise to ensure that your wind turbines meet the new requirements by the deadline. So visit us at our stand 1B09 in hall 1 – we look forward to seeing you!
