Vattenfall Taps Seaway 7 for HKZ Installs

Netherlands.The HKZ 1 & 2 wind farm is being developed by Vattenfall as the first subsidy-free wind farm in the Netherlands and is located approximately 30 km from the coast in the North Sea. Once fully operational, HKZ 1 & 2 will be capable of supplying 760 MW which will be enough to meet the electricity needs of approximately 1 million - 1.5 million households.In addition, Seaway 7 has been chosen as one of Vattenfall’s partners for the ongoing tender for the HKZ 3 & 4 offshore wind farm. This would add 76 monopiles and associated array cables to the program of work, if this development

Eni Pilots Wave Energy Converter

Italian multinational oil and gas company Eni has activated the Inertial Sea Wave Energy Converter (ISWEC), offshore Ravenna, capable of converting energy generated by waves into electricity, which will in the future enable Eni to convert mature offshore platforms into renewable energy generation hubs.The pilot plant was installed at the Ravenna offshore site by Eni’s Central Northern District and has been integrated into a hybrid smart grid system featuring photovoltaics and energy storage.It reached a peak power output of over 51 kW, or 103% of its nominal power. This technology is suitable

Mainstay to Build Wave Energy Device

harnesses the potential of marine energy in the form of pressure on the seafloor. mWave features a series of membranes which rests beneath the ocean’s surface on the seafloor, and as waves pass over the device, air inside the membranes is pushed into a duct and through a turbine to generate electricity.With Bombora’s initial design phase now complete, Mainstay, which has already delivered a purpose-built test tank for Bombora at Pembroke Dock, said it will begin building the all-steel structure imminently, with delivery of the fully-assembled device to the company’s ro-ro slipway

VA Offshore Wind: A Strong Foundation

Virginia officials have established a well-planned, extensive strategy to build out an offshore wind industry, including wind towers for electricity generation and the supply chain to support that extensive infrastructure and operations.  The State’s big picture is ambitious: developing 2,000 MW of offshore wind by 2028.As currently envisioned, VA’s offshore wind development will likely start this year with two 8-megawatt wind turbines 27 miles off the coast of Virginia Beach.  This is a Dominion Energy pilot undertaken in partnership with the Danish wind company Orsted.  The

milestone, as part of our staged testing and demonstration program in Nova Scotia. We have been working diligently with a wide range of stakeholders, including research organisations, academia and regulators to develop effective methods of monitoring the environmental interactions of this new form of electricity generation, and will continue to do so as we advance our technology. Our objective is to provide coastal and island communities with a robust, reliable and environmentally benign renewable energy solution.’’Nova Scotia Energy and Mines Minister Derek Mombourquette said, “Tidal

thousands of families with green power generated by the largest wind turbines in the country."This is the first step towards the full delivery of the park, expected this Summer. Starting up Norther is an important step towards ensuring supply security in our country. Norther will provide electricity to 400.000 families," said a press note.The installation of Norther's 44 turbines began earlier this month. It is the final and most crucial stage in the construction of Belgium's largest offshore wind farm.Twelve turbines have already been installed, and today, the first turbines

France to Test Floating Wind Turbines

The European Commission said on Monday it had authorized French subsidies to four offshore wind farm projects which are aimed at testing a new way of producing electricity from wind.The EU competition regulator said in a statement that the state aid was in line with EU rules as it was proportionate and could help develop a new type of technology to produce renewable energy.Three of the floating wind farms are in the Mediterranean Sea and one in the Atlantic Ocean.The demonstration wind farms will use a particular combination of turbine, floater and cables with a total installed capacity of 24 megawatt

European Offshore Wind Capacity up 18%

was up 91% – showing how quickly costs are falling and how much more bang you now get for your buck.WindEurope CEO Giles Dickson said: “Offshore wind continues to grow strongly in Europe. The total capacity expanded by a further 18% last year. Offshore wind now represents 2% of all the electricity consumed in Europe. And with a big pipeline of projects under construction and development, this number will rise significantly."“More and more governments are recognising the merits of offshore wind. Poland is the latest to embrace it with an ambitious plan to build 10 GW by 2040.

GE to Test 12MW Turbine in Netherlands

to install the Haliade-X 12 MW on the Sif site in Rotterdam, supporting Sif's ambition to remain at the forefront of developments in the offshore wind industry. The project also fits Sif's ambition to become entirely CO2 neutral as the Haliade-X 12 MW will supply carbon-free energy to the electricity grid.Activities in Rotterdam to prepare the site for future installation have just begun. The nacelle of the Haliade-X 12MW prototype will be assembled in Saint-Nazaire (France), while the three 107 meter-long LM Wind Power blades will be manufactured in Cherbourg (France), and the tower sections

Unit.The nacelles of this new offshore wind turbine will be initially manufactured at the SGRE factory in Cuxhaven, Germany, the world's largest plant for offshore wind turbine nacelles.The annual energy production of one SG 10.0-193 DD is sufficient to supply about 10,000 European households with electricity. This means that an offshore wind park composed of 20 of these turbines would cover the annual electricity consumption of a city the size of Liverpool

Offshore Wind Market Expected to Reach $50 bln by 2023

to grow over USD 49.74 billion by 2023 at an estimated CAGR of around 11.12% during the period 2017 to 2023.The growth in this sector can be attributed to the increasing demand for clean and reliable energy in order to reduce the global carbon emissions and to maintain ecological balance by generating electricity through renewable resources, said a report by Market Research Future.However, high initiating capital cost of the projects with high maintenance cost and logistics issues, can hinder the offshore wind market. Also, high tidal winds and bad weather conditions making it difficult to access the offshore

Meet WaveGem: New Offshore Power Platform

measures 21 x 14 x 7 m and is equipped with 150 KW power capacity, designed to produce energy courtesy of waves and sun. It is starting an 18-month test period on the site of SEM-REV operated by Central Nantes and located off the coast of Le Croisic in France.The system to convert waves energy into electricity relies on a smooth sea water flow through a turbine, with the constant water flow in different corridors enabling the platform to deliver consistent power. To increase the production of electricity, theunit is equipped with 70 sq. m. of solar panels.WAVEGEM is designed to be a simple and reliable
