Offshore Wind – A Brief History

, in the next 80 years the world is fortunate that it will have plentiful quantities of oil and gas – responsibly recovered and produced but in the future sipped, not guzzled, in highly efficient engines.In the next 80 years the world is doubly fortunate that it has the chance to mainstream electricity generation from renewables, again, primarily wind and solar.  These aren’t random, disconnected opportunities.  Like all progress, these choices are evolutionary, enabled by decisions made, and work started, years ago.In the spirit of looking back, here’s a brief review of

says, not minding that we’re comparing towering wind turbines to wind-service shipping.A similar discussion“There are also different regulations, such as the strict classifications for marine. But in the end, marine and wind are very much alike. In wind, the goal is to put as much quality electricity into the grid (as possible). In marine, the goal is to slash operating costs and fuel consumption.”Similarities aside, the timing of the company extending its global reach is perfect at this the dawn of US — and, it seems, Chinese — offshore wind expansion.

after a competitive tender. JDR, part of the TFKable Group, will design, manufacture and deliver 78.1 kilometers of aluminium core inter-array cables and a range of cable accessories, including repair joints and connectors.The inter-array cables connecting the 58 Siemens 8.4MW turbines, will carry electricity to an offshore substation for transmission to the offshore grid. The offshore wind power generated is transmitted by a 33kV cable system with hang-offs and connector terminations for 128 cable ends. The cable will be assembled in JDR’s Hartlepool facility, with delivery expected by the end

of building a sustainable and efficient aquaculture industry,” said Kevin Kosiko, Managing Director ABB Energy Industries.“The unmanned fish pens will be remotely controlled by a feed barge located 400 meters away. This reduces the need for human intervention and thereby cuts fuel and electricity consumption and will also enable new solutions for fish farming offshore and onshore with a focus on fish welfare, traceability and food safety,” Kevin added

Heerema Wins Hollandse Kust Zuid Alpha Project

Zuid (HKZ) Alpha project, one of the largest offshore wind farm zones being developed in the North Sea off the Dutch coast.The award entails the transport and installation of the HKZ Alpha HVAC platform. This platform is a high-voltage substation, an essential component of offshore wind farms that run electricity to the mainland, in this case the Maasvlakte.The 2,800-metric-ton jacket for the HKZ Alpha substation will be installed in the second quarter of 2020 followed by the 3,800-metric-ton topside in the fourth quarter of 2020, the Dutch offshore contractor said.Heerema said the installation will be

Offshore Wind: California's New Gold Rush

California Dreamin': In CA, offshore wind has unlimited potentialWhen it comes to States promoting renewable, non-fossil electricity generation, California surely leads the list, from utility-scale regional grids to individual rooftop solar panels.In fact, a December 2018 update from the California Energy Commission (CEC) estimates the state may already have exceeded an initial renewable generation goal of 33% by 2020.  CEC estimates that in 2018 that generation number was already 34%. You can note (below) that wind accounted for 29% of the almost 100,000 GWh of renewable electric generation

bouts of bad weather delayed the project earlier this year, said Swedish power company Vattenfall.The European energy company is building the 750-megawatt Hollandse Kust Zuid 1 & 2 wind farm off the coast of The Hague and Noordwijk. Vattenfall said it expects the wind farm will begin generating electricity by the end of 2022, ultimately supplying power to up to 1.5 million households.Dozens of researchers at the North Sea will be working day and night through the summer to learn as much as possible about the site where the wind farm will be erected. Using high-tech equipment, they are performing

UK Govt Backs Aberdeen Subsea Engineering Hub

280,000 jobs, meets almost half of the country’s energy needs and has contributed £334 billion in taxes toward its vital public services.In March, the UK government also launched the offshore wind sector deal, an agreement with industry which aims to deliver a third of the UK’s electricity through offshore wind and seize on export opportunities that could be worth up to £2.6 billion by 2030

Europe Leads in Ocean Energy

European tidal stream installations reached 26.8MW, and wave energy installations 11.3MW in 2018, according to yearly statistics published by Ocean Energy Europe.Europe continues to lead the world in ocean energy deployments, and last year its tidal projects produced record volumes of electricity.Annual installations - 3.7 MW of tidal stream capacity was put in the water in 2018. This represents more than twice the capacity installed in 2017, making this a solid year for tidal activity.26.8 MW of tidal stream technology has been deployed in Europe since 2010. Of this, 11.9 MW is currently operating

and maintenance of this phase feeding into subsequent phases.The turbines connect to the onshore power conversion unit at the Ness of Quoys where the low voltage supply will be converted for export to the local distribution network. On completion this phase of the tidal array will generate sufficient electricity to supply 2,600 homes.The supply chain for this phase of the project is spread across the United Kingdom, Europe and North America. 43% of the project’s expenditure is in Scotland and includes companies in Caithness, and Ross and Cromarty

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
