Global Tech I is the name of an offshore wind farm in the German Exclusive Economic Zone in the southern North Sea that went into operation in 2015.
location
The wind farm is located approx. 93 kilometers northwest of the island of Juist on an area of 41 km² and water depths of 39 to 41 meters. At the time of commissioning, it was the furthest offshore wind farm from the coast.
history
Global Tech I was planned by geologist Hans-Jürgen Kothe until it was approved by the Federal Maritime and Hydrographic Agency (BSH). Windreich took over the further development up to commissioning . The offshore wind farm comprises 80 wind turbines for an annual standard energy capacity of 1400 GWh . The wind farm was officially put into operation on September 2, 2015.
The first project phase comprised the construction and operation of 80 Areva Multibrid M5000 wind turbines with an output of 5 MW and a total nominal output of 400 MW. The investment volume in this phase was 1.8 billion euros.
The project planning of the offshore wind energy park was carried out by Nordsee Windpower GmbH & Co. KG , and was continued by the project company Wetfeet Offshore Windenergy GmbH . The operator is Global Tech I Offshore Wind GmbH , based in Hamburg . The project company for the potential offshore wind farm Global Tech II acquired Vattenfall in 2016 .
The European Commission funded the project as part of the European Energy Program for Recovery (EEPR) with EUR 58.55 million.

realization
At the request of Nordsee Windpower ( Westerholt ) on July 2nd, 2001, the construction and operation of 80 wind turbines were approved by the BSH on May 24th, 2006 in accordance with the Marine Plant Ordinance . The project company Global Tech I Offshore Wind GmbH commissioned a builder to the Hochtief belonging group Hochtief Construction AG with the construction of 80 wind turbines. This EUR 175 million contract was completed in the second half of 2012, with the original plan for commissioning at the end of 2013.
To safeguard the construction work, a 500 m safety zone was set up around the wind farm construction site in July 2012. The floating transformer station was brought to the construction site from Rotterdam at the beginning of May 2013, where it was installed on the foundations as a residential and transformer platform .
System assembly
The order to manufacture the 80 wind turbine foundations was awarded in March 2011 in two lots. By autumn 2012, the first 40 three-legged steel foundation structures (so-called tripods ) had been manufactured by ARGE Tripod Global Tech 1 (a consortium of WeserWind GmbH and Erndtebrücker Eisenwerk ) and SIAG Nordseewerke , and construction began. Since SIAG Nordseewerke were unable to fully carry out the order due to its insolvency, the manufacture of the remaining tripods was outsourced to another consortium. With a height of around 60 meters with a water depth of around 40 meters and a weight of almost 850 tons on a base area of 30 meters by 30 meters, such a tripod forms a stable foundation for each wind turbine.
From September 2012, the installation ship “ Innovation ” gradually picked up the prefabricated wind turbine foundations (tripods) from Bremerhaven and erected them at the designated place in the construction site. By September 2013, 44 of the 80 tripods had been set, from the beginning of 2013 they were wired.
The tower and gondola installation took place from September 2013 onwards, initially with the installation ship “ Thor ”. From December 2013 the crane lift ship “ Brave Tern ” was operated by Fred. Olsen Windcarrier used for support, from March 2014 also the crane lift ship “Bold Tern”. By mid-March, the gondolas were mounted on 15 towers; in mid-June 2014 there were over 60 towers and gondolas and over thirty rotor stars. The last system was installed at the end of August.
Network connection
Innerpark cabling
The contract for the supply and installation of cables for internal wiring of the individual wind turbines within the wind farm to the transformer platform was to a consortium of North German Seekabelwerke GmbH and Global Marine Systems Ltd awarded. Work on laying the 120 km of submarine cables should begin in the second half of 2012. At the end of February 2013, the relocation that had begun was reported for the first time. The washing of the medium-voltage cables into the seabed began in early summer 2013.
Transmission network
The order of the responsible for the grid connection TenneT TSO for the construction of the converter platform " BorWin beta " to accommodate the power converter for high-voltage direct current ( BorWin2 ) of the recovered energy to the country was established in July 2010 by Siemens Energy Sector at Nordic Yards given . The Warnemünder Werftbetrieb built the platform, Siemens Energy equipped it with electrotechnical equipment. In the summer of 2012, it was supposed to be towed to its intended location in the North Sea, but the installation of the converter platform was delayed by over a year. In order to meet the completion date anyway, the converter platform " BorWin alpha " on the OWP BARD Offshore 1 and the existing BorWin1 were used. The three-phase submarine cable laid from November 2012 from the Global Tech 1 construction site to the "BorWin beta" converter platform, which had not yet been built, was first connected to the neighboring, already connected "BorWin alpha" converter platform. Due to difficulties with the power transfer at “BARD Offshore I” via BorWin1, there were also problems with the power connection of Global Tech I due to the shutdown due to troubleshooting. At the end of 2014, the grid connection from Global Tech I was transferred to the HVDC “BorWin 2” the new converter platform "BorWin beta" changed. When Siemens handed over to TenneT TSO, “BorWin 2” went into commercial operation.
electric wire
The order for the laying of the cables (120 km submarine cable , 75 km underground cable) of the HVDC “BorWin 2” from the converter platform at sea via the island of Norderney to the grid connection point at the Diele substation near Papenburg was placed by Transpower (now: TenneT TSO ) in Awarded June 2010 to a consortium of Siemens Energy and the cable manufacturer Powerlink (now: Prysmian ). The route runs parallel to BorWin1 . Construction work on Norderney and Hilgenriedersiel began in summer 2010 . The cable was laid, but the completion of the connection was delayed due to a delay in the “BorWin beta” converter platform. It was originally planned for spring 2013.
Reassignment
Due to a lack of network connection capacities , the Federal Network Agency undertook a settlement before the Düsseldorf Higher Regional Court to partially re-regulate the allocation of capacities. After completion of the BorWin3 offshore HVDC system, the Global Tech I lines will be connected to the BorWin Gamma offshore platform in mid-2019 . The Hohe See offshore wind farm is also connected there . The capacity released at BorWin2 / BorWin beta is then available to the Albatros offshore wind farm .
