REETEC launches new aviation obstruction markers for onshore and offshore wind turbines according to latest certification standards

18.06.2018 //

  • Universally deployable aviation obstruction marker system from REETEC in-house production.
  • Preparation for all approved “night identification on-demand systems” (BNK).
  • Lighter, more compact and lower-maintenance than previous generation.

After completion of the development work, prototypes of the new luminaire series were initially built in the company's own production facility in April 2017; after successful certification of the optical characteristics, REETEC is now starting its series production. Consistent simplification of components and design resulted in a significant cost reduction. At the same time, the robustness and longevity of the luminaires were key development objectives.

The most important improvements at a glance:

  • The number of LED levels was minimized - this design optimisation allowed for a much more compact model shape.
  • Newly designed, robust Plug'n'Play GPS solution with integrated twilight switch.
  • Highly flexible system that can be easily adapted to local requirements via network / web interface.
  • Individually configurable, therefore suitable for retrofit.

“The above are all decisive advantages of the new aviation obstruction markers compared to the previous generation. Our goal was to maintain the tried and tested robustness while at the same time implementing technical innovations and a cost-efficient production,” explains Carsten Bredemeier, Head of Development at REETEC.

Comprehensive environmental testing under real life conditions

The prototypes underwent a comprehensive test program: examinations in climatic and pressure chambers, salt water spray tests as well as acceleration and shock tests that go beyond typical environmental conditions and manufacturer requirements. The optical properties have been tested by an accredited laboratory and were successfully certified by the relevant authorities according to current AVV and ICAO guidelines, which is a prerequisite for marketing approval.

"Within only one year we have developed, extensively tested and successfully certified a completely new product. Our new aviation obstruction markers pay tribute to the rapid development in the field of LED technology and raise our product portfolio to a new technical level. The market interest is extraordinarily high, as the system is also very well suited for retrofit measures due to its modularity," says Claus Sejersen, Sales Director at REETEC. The results which REETEC repeatedly achieves on the basis of its broad experience and comprehensive know how are an integral part of the success story of the Bremen-based wind energy company from day one: REETEC has been producing aviation obstruction markers for onshore and offshore wind turbines since 1998.

REETEC presents itself with new branding as REETEC EDF Renewables to onshore and offshore wind energy market

07.05.2018 //

  • Following the recent rebranding of EDF Energies Nouvelles’ international subsidiaries in around 20 countries to be EDF Renewables, REETEC’s branding is being adapted according to the new corporate identity.

Bremen/Germany, May 7, 2018 – To support its expansion in the international renewable energy market, EDF Energies Nouvelles has bolstered its corporate identity through EDF Renewables, the brand for its international subsidiaries. In line with the EDF Group’s goal of doubling its renewable energy capacity in France and worldwide by 2030, EDF Energies Nouvelles continues to expand in its core markets – France, Europe and the United States – and into markets with a high development potential, such as Latin America, Asia and the Middle East.

When it comes to wind energy, Germany is a key European market for the EDF Group. Together with REETEC – which is part of the EDF Energies Nouvelles Group - the Group plans to drive forward the turnaround towards renewable energy concepts. To honor the long-standing heritage of REETEC and its position as an established market player, the new brand is now REETEC EDF Renewables. OWS Off-Shore Wind Solutions – acquired by REETEC in 2017 – will adopt the new brand in 2019.

REETEC repositions itself with unique onshore and offshore service portfolio at the wind energy market

01.02.2018 //

  • The REETEC merger with Off-Shore Wind Solutions (OWS) creates an extremely powerful independent competence centre for onshore and offshore services.
  • The Emden Offshore Service Centre (EOSC) offers customers access to a service hub for wind turbine generators of the North Sea plus a highly qualified full maintenance concept.
  • With EDF Energies Nouvelles Group, REETEC benefits from a strong, globally oriented stakeholder with ambitions to drive expansion of wind energy concepts on an international level.

Bremen/Germany February 1st, 2018      As an independent full service provider with over 20 years of industry experience, REETEC sees itself as a partner of manufacturers and operators of wind farms on equal footing. Its comprehensive know how is based on practical learning curves – not least due to experience with developing prototypes – which is passed on directly to customers via qualified employees. The former can order services on a stand-alone basis or packaged as a turn-key project.

The OWS integration means a significant expansion of the current range of services from electrical engineering, grid connection, electrical and mechanical assembly of wind turbine generators, operation and maintenance (O&M) services, major component replacement, rotor blade and tower services to aviation obstruction markers.

Compelling combination of competence, technology and infrastructure

Currently, an unparalleled pan-European service hub for major component replacement is being built together with offshore wind farm specialist OWS: the “Emden Offshore Service Centre“ (EOSC), which offers cost efficient full service concepts as well as modular solutions. Medium-term planning will see availability of technology and engineering with a capacity to service 500 wind turbine generators:

  • Own service dock and service hall in which rotor blades with a length of 50-60 meters and entire nacelles can be refurbished.
  • Modern 24/7 control centre, including remote supervision and connection to the predictive maintenance centre of EDF Energies Nouvelles (e-DC).
  • Location on the border of the Netherlands offers a wide deployable radius comprising the entire North Sea.
  • Access to a jack-up service vessel with a 500 tons crane.

"Wind energy is a people’s business. As an "honourable merchant from Bremen", we have gained a lot of trust in the market since 1996 – be that with clients or by now 350 employees. We know all facets and challenges of wind energy services like no other. Obvious proof of this competence is that REETEC/OWS is the first independent service provider to close a 10-year operation and maintenance service contract for the offshore wind farm BARD Offshore 1 (BO1) with the owner and operator Ocean Breeze Energy," says Detlef Lindenau, Managing Partner REETEC.

Seeing the big picture

Since 2007, REETEC is part of the EDF Energies Nouvelles Group (EDF EN) – a global player with ambitious goals for renewable energies according to the CAP 2030 strategy of EDF Group: the installed output of 28.000 MW today shall grow to 50.000 MW by 2030. One of the key drivers will be wind energy. With its technical expertise, REETEC/OWS is an important contributor to advance the industrialisation of the wind industry together with the international strength of the EDF EN group.
