Repowering in Iowa, USA
The Global Wind Service project team successfully completed the project of dismantling the aging wind turbine parts and exchanging them with new parts.
The 97.7 MW wind farm produced energy to supply around 33,000 homes annually. However, with the upgrades made, the wind farm now produce 105.1 MW providing 35,000 homes annually.
Over a period of 18 weeks in 2017 Global Wind Service (GWS) worked on the Bearkat I project. A 57 turbines project in Texas, USA. During that time more than 100 technicians have worked at site and a total of 14 cranes were used.
- 57 Vestas v126 3.45MW turbiens
- GWS safely delivered a high quality project, and overcame multiple extreme weather and logistical challenges to complete the installation work on schedule
In 2016-17 Global Wind Service provided skilled manpower for the installation of Clyde Extension in the Scottish Lowlands.
- 54 Siemens 3.2MW direct drive turbines
- Comprehensive scope of pre-assembly, installation, mechanical & electrical completion, cold-commissioning, 500-hour service

Wikinger 500-hour service
Global Wind Service (GWS) was contracted by Adwen to perform the 500-hour service on the Wikinger offshore wind farm starting in May 2017.
A team of 40 technicians and 2 site managers are working on the 70 x 5MW-135 Adwen turbines installed. The 500-hour service consists of the following tasks:
- Bolt check of blades, hub, and tower
- Service maintenance of transformers, heli-hoist, lower deck, nacelle, and tower
The Wikinger offshore wind farm is located in the Baltic Sea, approx. 75km from the German mainland, close to the Island of Rügen, with Sassnitz as baseport.
A journey with GE towards mutual success
Keeping pace in this rapidly evolving industry is the result of building competencies and developing key relationships over time. The historic installation of Block Island Wind Farm was a result of such efforts and was a three-step journey with GE.
- November 2013 – Alstom Haliade 150 6MW offshore turbine, Belwind.
- April 2016 – GE Haliade 150 offshore wind turbine prototype, National Test Centre for Large Wind Turbines, Østerild.
- August 2016 – Five GE Haliade 150-6MW, Block Island.
Watch Case Study Video
In 2016, Global Wind Service (GWS) provided manpower for the installation of five GE Haliade-150 6MW turbines.
- This was the first US offshore wind farm to be installed.
- The project was completed ahead of schedule.
- GWS supplied 16 technicians.
Gwynt y Môr
In 2014, Global Wind Service (GWS) provided technical manpower for the installation of 160 Siemens 3.6MW turbines, alongside the client’s installation crews.
- At the time of commissioning, Gwynt y Môr was the second largest wind farm in Europe.
- The project took 2 years to complete.
- Throughout all stages of the construction (from pre-assembly to commissioning) GWS has been a preferred supplier of turbine technicians, expertise and services.
Gwynt y Môr officially opened on 18th June, 2015.
Mid Hill Extension
In October 2014, Global Wind Service (GWS) completed the installation of 8 Siemens 2.3MW turbines for the Mid Hill wind farm extension 20 miles south of Aberdeen, Scotland.
- The first turbine was successfully installed at 8:40 on the 1st September.
- Installation rate of 1 turbine every 4 days thanks to a highly efficient project team and good weather.
- GWS was responsible for the craning and installation, project management and health and safety on site.
GWS also installed Mid Hill 1 in May 2014, which consists of 25 Siemens 2.3MW turbines.
Global Tech I
In 2014, Global Wind Service (GWS) provided technical manpower for installation on the Global Tech I wind farm in the German North Sea. The contract, held by Fred. Olsen related company Fred. Olsen Windcarrier was for the installation of AREVA 5MW M5000 turbines.
- New record: eight towers and nacelles installed in one week – including 10 hour transfers.
- GWS supplied 65 technicians to the installation phase of this project.
- This was one of the first projects to feature the AREVA 5MW wind turbines.
The final two complete turbines were installed at the end of August 2014.
SIEMENS Service in France & Germany
Global Wind Service (GWS) undertook bolt inspections on Siemens 1.3MW and 2.3MW turbines in Germany and France in 2013. The inspections were part of the yearly service work inside the Siemens turbines. GWS completed in three different parts of France and at several smaller sites in Germany. We also performed the generator alignment on the 1.3MW turbines in France.
The French project included:
- Northern France sites: Quesnoy 1, 2 and 3 & Val de Noye
- Eastern France sites: Les Grandes Chapelles & Longuyon
- Southern France sites: Murat, Haut Languedoc, Haut Cabardes & La Salesse
In France, GWS technicians used Siemens tools, and there was a SWP site manager available on each site. In Germany, we received a list of 1.3MW & 2.3MW turbines requiring bolt inspections and these were located all over Germany. We optimised our route and introduced start and finish dates for the specific turbines, which Siemens approved. The service team then worked on the turbines using our own tools and service-van.
Sere Wind Farm, South Africa
Global Wind Service’s (GWS) first contract in South Africa was on the Sere Wind Farm owned by Eskom, the South African state-owned electricity group. Sere is a 100MW development on the 3,700 ha site near Vredendal in the Western Cape, approximately 300km north of Cape Town.
GWS trained local technicians to work alongside their own teams on the project, which comprised 46 Siemens 2.3MW turbines with a hub height of 115m and a rotor diameter of 108m.
Construction started in the second half of 2013 and was scheduled to supply electricity to the grid by the first half of 2014. The Sere wind farm takes its name from the Nama word meaning cool breeze.
With wind capacity in South Africa estimated to be well over 10,000 MW, the Western Cape is a region with an attractive wind resource. It is hoped the wind farm will be a catalyst for the development of renewable energy in South Africa and throughout the rest of the continent. The project will also conserve scarce water resources as it uses little or no water in the production of clean electricity.
In 2012 Siemens Energy secured its first wind turbine orders in Africa, with a total capacity of 100MW. Nareva Holding and Siemens signed a contract for the delivery of a total of 44 2.3MW wind turbines for the Haouma and Foum El Oued Wind Power Plants in Morocco.
The Haouma wind farm project is located in northern Morocco, approximately 30 km east of Tangier, and six km south of the Mediterranean coast. The 50MW Haouma development features 22 Siemens SWT-2.3-93 wind turbines. Foum El Oued is in one of the windiest areas of Morocco in the municipality of Laâyoune, 9km south east of the port of Laâyoune in southern Morocco. Also 50MW, Foum El Oued will feature 22 SWT-2.3-101 wind turbines.
Since the end of November 2012 Global Wind Service (GWS) has supported Siemens Morocco with a number of experienced painters and fibre technicians. It has been a great experience for our technicians, who have been given the opportunity to work and live in a different and interesting culture.
Korat Wind Farm, Thailand
Global Wind Service (GWS) was contracted in 2012 to provide services in the construction of the Korat I & II wind farms in Thailand, considered to be Southeast Asia’s largest wind farms, with a generating capacity of about 200MW. The project was part of ambitious plans by local company Wind Energy Holding Co (WEH) to develop wind farms generating a combined output of 1,000MW by 2020.
GWS was contracted by Siemens Thailand to support them with experienced supervisors during the construction and service phase. The last turbines were installed at the end of 2012 when two technicians were left on site to support the local service team with valuable knowledge and experience.
Korat I & II were our first projects in Thailand and provided GWS with valuable operating experience in this part of the world.
Musselroe Wind Farm, Australia
In November 2012 Global Wind Service (GWS) technicians started work on the Musselrow Wind Farm in the Cape Portland area of Tasmania. It has 56 Vestas wind turbines with a generating capacity of 168MW.
The team were involved in all aspects of the work, including preparation, offloading, installation, mechanical and the electrical completion of the turbines.
GWS has a close relationship with Vestas Australia, working with them on a number of projects. To comply with Australian legislation, GWS provided a number of its technicians with two-year working visas.
