Dutch offshore companies realised a unique operation in the North Sea. Under the direction of Seaway Heavy Lifting, one of the world's largest convertor platforms - a ‘power socket at sea' - is installed to the west of Sylt, the East Frisian Island. Siemens built the SylWin alpha platform. It is so large and heavy that the ingenious 'float-over method' has been used to lift it from a pontoon onto the already installed ‘jacket' (the base of the platform). This approach has been used successfully in the Gulf of Mexico and in the Far East, but is the first time that a platform as large as SylWin alpha was installed using the method in the North Sea.
Siemens commissioned Seaway Heavy Lifting (based in Zoetermeer, the Netherlands) to perfor
• Further step in ramping up serial production of innovative offshore wind turbine rated at 6 megawatts
• Tested and certified for 25 years lifetime
Siemens Energy has obtained type certification by certifying body DNV GL for the company's innovative D6 offshore wind turbine. The model Siemens SWT-6.0-154 is equipped with a modern direct drive generator, rated at 6 megawatts (MW) and equipped with a 154 meter rotor. The official certificate is a further step in ramping up the serial production of the turbine. The certification process included DNV GL experts being given full access to the engineering and Siemens assembly facilities in Brande as well as testing facilities at Oesterild, Denmark and
DNV GL CONFIRMS SAFETY AND RELIABILITY OF WIND TURBINES INSTALLED AT ONE OF AFRICA’S LARGEST WIND FARMS
Hamburg/Germany, 25 July 2014 - As part of the installation phase at one of Africa's largest wind farms Ashegoda in Ethiopia, DNV GL has inspected wind turbines of the French manufacturer Vergnet. DNV GL confirmed the compliance of the installed wind turbines with DNV GL's A-Design Assessment. The wind farm shall help to reduce the occurrence of blackouts in Ethiopia. The country has some of the best wind resources in the world and has a fully developed plan to get up to about 7 GW of wind energy by 2030.
"Certification and design validation are essential for technically reliable wind turbines", explains Mersudin Bajric, Project Manager for Renewables Certification at DNV GL. The A-Design Assessment comprises a thoroug
• 144 MW Westermeerwind in Holland's IJsselmeer lake to feature 48 Siemens direct drive wind turbines
• First turnkey project for Siemens' offshore business
• Deal includes 15-year full service contract
Siemens Energy has received an order for the Netherlands' largest near shore wind farm. Designed to generate 144 megawatts (MW) of wind power, the Westermeerwind project with 48 direct drive wind turbines is also the first wind power plant Siemens Wind Power's Offshore unit will erect for handover to the customer on a turnkey basis. Within the framework of a 15-year comprehensive maintenance contract, the owner will benefit from Siemens' guaranteed availability.
Zwijndrecht 29. July 2014 - GeoSea has just finalized the installation of 77 foundations on the DONG Energy Borkum Riffgrund 1 offshore wind farm. The installation works, including transport from the fabrication yard to the marshalling harbor, have proceeded in record times and finished ahead of schedule.
The 77 units consisted of monopiles, weighing between 495 tonnes and 684 tonnes and measuring a diameter of 5.9 metres and a length of up to 66m, and transition pieces of weighing around 330 tonnes.
The installation vessel Pacific Orca, supplied by DONG Energy, is currently sailing to Flushing where GeoSea will start the mobilization works for the Suction Bucket Jacket, a new type of foundation also to be installed on the BKR1 field.Read more
