Case Study: Global Tech I
Global Tech I occupies about 41 square kilometres approximately 180 kilometres from Bremerhaven and 138 kilometres northwest of Emden. The wind farm comprises 80 AREVA 5 megawatt M5000 turbines with a hub-height of 90m above sea level and a rotor blade diameter of 116m. Total output is 1.4 billion kilowatt hours per year – enough electricity to power 445,000 homes.
The loading of the towers and nacelles took place at the offshore terminal at ABC Peninsula Docks of the logistics provider BLG in Bremerhaven. The excellent facilities and experienced Global Wind Service (GWS) ground technicians meant that the process ran smoothly with a complete load out of four towers and nacelles in just over 24 hours. Pre-assembly and loading of the rotor stars was performed at JadeWeserPort in Wilhelmshaven.
Both vessels were equipped with a flexible deck layout enabling them to install either four towers and nacelles or two complete rotor stars in a single deployment. This set up allowed the vessels to work together and take full advantage of the fluctuating favourable weather conditions.
During the installation campaign, utilising the combined efforts and expertise of Fred. Olsen Windcarrier, DELPRO Wind and GWS, a new record was set of eight towers and nacelles installed in one week. This included 10-hour transfers for both vessels to and from Bremerhaven to the construction site – a distance of 180 kilometres.
“Global Tech I was an excellent example of how the Fred. Olsen related companies can work together to deliver a market-leading performance executed to the highest safety standards under a single contract interface. We hope that this teamwork will be repeated in many projects to come.”
Lars Petersen, CEO, Global Wind Service.
“Both vessels and all members of the crews and construction teams worked flawlessly on this project. We achieved many new company performance records and delivered on time and on budget for the client. We are very proud of this and we are very much looking forward to working in this way again.”
Even Larsen, Head of Commercial and Project, Fred. Olsen Windcarrier.
