Enerpac has introduced a new portfolio of hydraulic bolt tensioners for offshore wind power fastening applications.
The PGT-Series Double Deck and Single-Stage Bolt Tensioners provide high performance in tight spaces typically found in wind turbines. Key features include auto-retract pistons, over-stroke protection and auto-engage nut rundown. The FTR-Series Foundation Bolt Tensioners are designed specifically for tensioning wind tower foundations bolts.The FTE-Series Elliptical Foundation Bolt Tensioners provide a fastening solution on wind tower foundation applications where limited space between the stud and wall prevent the use of standard tools. They feature an elliptical geometry, which enables fit in narrow access foundation applications without reducing load capabilities.
Dutch offshore foundations manufacturer Sif and Japan-based East Winds Asia (EWA) have developed a method to transport and store offshore wind foundations in Asian harbors which is said to eliminate the need for additional infrastructural investments.
The method includes the foundations being transported on a semi-submersible ship, and once it arrives in a harbor, the cargo is unloaded and foundations are brought into the harbor on barges.
Deepwater Wind on Wednesday announced a series of appointments for its 120-MW Skipjack wind project off the coast of Maryland as it gears for the implementation of the scheme.
The project's development manager will be Joy Weber, who will be in charge of building developments. Whitney Fiore, of St Michaels, will serve as manager of permitting and environmental affairs. Deepwater plans to submit permit applications in 2019.
Ad Hoc Marine Designs is championing the feasibility of its Typhoon Class Swath design as the best suited windfarm vessel to meet significant wave height requirements for future rounds of offshore windfarms.
The company has recently released details of its new Walk to Work (W2W) Swath CTV capable of servicing the next generation of Round 3 windfarms, giving operators a “better alternative” to ordering larger vessels.
“The next round of windfarms and the future vessel requirements for higher wave height and being longer at sea is due to windfarms being placed further out to sea,” said John Kecsmar, naval architect, Ad Hoc Marine Designs.
“Our Typhoon Class Swath design is the best one on the market to meet these requirements going forward.”
Kecsmar refutes the view that Swath designs have more resistance at higher speeds, increasing fuel consumption and operating costs for operators. Existing CTV designs are comparable.
Mono-bucket foundation technology for offshore windfarms could be tested on the Deutsche Bucht Wind Farm offshore Germany.
The technology, developed by Universal Foundations, a Fred Olsen company, was picked for the Bucht wind farm as a pilot project. Two would be added to the farm, with accompanying winds turbines, adding 17MW to the 252MW project.
Deutsche Bucht is Northland Power’s third offshore wind project. It is in about 40m water depth, 95km northwest of the island of Borkum in the German North Sea.
The waste-to-energy facility is due to begin operation in 2018. The building was completed with University of Hull input in the hopes of increasing access to education about renewable energy.
A key element of the new, £200m energy from waste power plant ‘Energy Works’ has been completed, paving the way for new research into renewable energy technologies.
Spencer Group, a multi-disciplinary engineering business, has steered the Energy Works scheme in Hull from concept to delivery and the company is now playing a part in construction of the vast green energy facility.
Up to 150 Spencer Group staff and sub-contractors have been delivering the £35m package of civil and structural works for the green energy power plant. The team has now completed the Energy Academy, a learning, research and development facility created in partnership with the University of Hull.
The power produced by any given wind turbine varies with the third power of the wind speed. Therefore, an 8-MW turbine designed for the North Sea would theoretically produce over 140 MW if taken into the Roaring Forties. It would obviously have to be strengthened considerably (Wilson proposed a new type of wind turbine that should be more reliable in high winds) but if we lower the power output to 50 MW per turbine there would still be vastly more available energy to power all the earth’s needs almost forever.
China's largest wind turbine installation vessel, the "Longyuan Zhenhua 3", could boost international cooperation in the South China Sea, experts said Sunday.
The vessel, which went into trial service on Sunday in Nantong, East China's Jiangsu Province, has a lifting capacity of 2,000 tons, making it the largest of this kind in the world, currently, news site people.cn reported.
Operated by Statoil in partnership with Masdar, the 30 MW wind farm consists of five 6 MW turbines and is located 25 kilometers offshore Peterhead in Aberdeenshire, Scotland and will power approximately 20,000 households.
International engineering and operations support services contractor ODE, an integral part of the DORIS Group, has been awarded two Framework Agreements for Electrical Project Management, and for Wind Turbine Generator (WTG) Project Engineering and associated Project and Interface Management.
The framework agreements will run until 2021 and apply to Vattenfall WindKraft, its subsidiaries and affiliated companies across Europe, including the United Kingdom, Germany, The Netherlands, Denmark and Sweden.
