Deutsche Windtechnik Achieves a New Milestone: Maintenance for Siemens SWT-3.6 at the Riffgat Offshore Wind Farm Press Release
Press Release Contact Karola Kletzsch Corporate Communications Telephone +49 421 69 105 330 Mobile +49 172 263 77 89 E-Mail k.kletzsch@ deutsche-windtechnik.com Bremen 25.04.2019 Page 1/3 Deutsche Windtechnik achieves a new milestone: Maintenance for Siemens SWT-3.6 at the Riffgat offshore wind farm Deutsche Windtechnik has been awarded the contract to provide maintenance for 30 Siemens SWT-3.6-120 wind turbines at the Riffgat offshore wind farm as part of an EU tender procedure that was initiated by EWE Offshore Service und Solutions GmbH (EWE OSS). The contract begins in June 2019. The two companies have been working together closely for more than two years at the offshore wind farm alpha ventus, and their cooperation will now continue at the Riffgat offshore wind farm as a result of the EU tender. The contract includes basic maintenance, troubleshooting, remote fault elimination, spare parts management, maintenance of safety equipment and testing of electrical equipment in accordance with DGUV V3. This makes Deutsche Windtechnik, which operates independently from manufacturers, the first ISP (Independent Service Provider) in the world to provide maintenance for Siemens SWT-3.6 turbines. "We are very pleased to be able to provide the service for this great system technology. Utilising synergies and planning for the long-term enable operators to save significant costs with us. This also applies to the Borkum Cluster that EWE OSS is planning. Deutsche Windtechnik is an optimal service partner that delivers customised added value from Borkum/Emden to customers who are active in the Borkum Cluster," said Jens Landwehr, Managing Director of Deutsche Windtechnik Offshore und Consulting GmbH. -
Gravity-Based Foundations in the Offshore Wind Sector
Journal of Marine Science and Engineering Review Gravity-Based Foundations in the Offshore Wind Sector M. Dolores Esteban *, José-Santos López-Gutiérrez and Vicente Negro Research Group on Marine, Coastal and Port Environment and other Sensitive Areas, Universidad Politécnica de Madrid, E28040 Madrid, Spain; [email protected] (J.-S.L.-G.); [email protected] (V.N.) * Correspondence: [email protected] Received: 27 December 2018; Accepted: 24 January 2019; Published: 12 March 2019 Abstract: In recent years, the offshore wind industry has seen an important boost that is expected to continue in the coming years. In order for the offshore wind industry to achieve adequate development, it is essential to solve some existing uncertainties, some of which relate to foundations. These foundations are important for this type of project. As foundations represent approximately 35% of the total cost of an offshore wind project, it is essential that they receive special attention. There are different types of foundations that are used in the offshore wind industry. The most common types are steel monopiles, gravity-based structures (GBS), tripods, and jackets. However, there are some other types, such as suction caissons, tripiles, etc. For high water depths, the alternative to the previously mentioned foundations is the use of floating supports. Some offshore wind installations currently in operation have GBS-type foundations (also known as GBF: Gravity-based foundation). Although this typology has not been widely used until now, there is research that has highlighted its advantages over other types of foundation for both small and large water depth sites. There are no doubts over the importance of GBS. -

The outlined analysis validates the dynamic wake meandering (DWM) model based on loads and power production measured at an onshore wind farm with small turbine distances. Special focus is given to the performance of a version of the DWM model that was previously recalibrated at the site. The recalibration is based on measurements from a turbine nacelle- mounted lidar. The different versions of the DWM model are compared to the commonly used Frandsen turbulence model. 5 The results of the recalibrated wake model agree very well with the measurements, whereas the Frandsen model overestimates the loads drastically for short turbine distances. Furthermore, lidar measurements of the wind speed deficit as well as the wake meandering are incorporated in the DWM model definition in order to decrease the uncertainties. 1 Introduction Wake models are a key aspect in every site-specific load calculation procedure. The used wake model has significant impact on 10 predicted loads and the power output of the whole wind farm, hence, an accurate wake model is of major importance for a wind farm design optimization process. -

EUR Kastrup Airport The Middelgrunden Wind Farm is situated a few kilometres away from the centre of Copenhagen. The offshore turbines are connected by cable to the transformer at the Amager power plant 3.5 km away. Kongedybet Hollænderdybet Middelgrunden Saltholm Flak 2 From Idea to Reality The idea of the Middelgrunden wind project was born in a group of visionary people in Copenhagen already in 1993. However it took seven years and a lot of work before the first cooperatively owned offshore wind farm became a reality. Today the 40 MW wind farm with twenty modern 2 MW wind turbines developed by the Middelgrunden Wind Turbine Cooperative and Copenhagen Energy Wind is producing electricity for more than 40,000 households in Copenhagen. In 1996 the local association Copenhagen Environment and Energy Office took the initiative of forming a working group for placing turbines on the Middelgrunden shoal and a proposal with 27 turbines was presented to the public. At that time the Danish Energy Authority had mapped the Middelgrunden shoal as a potential site for wind development, but it was not given high priority by the civil servants and the power utility. -
