Offshore Wind – A Brief History

records: “The price of oil skyrockets and so does interest and research in wind turbines and the power they generate.”Then, events quicken:-- 1978 – President Carter signed the Public Utility Regulatory Act, requiring companies to buy a certain amount of electricity from renewable energy sources, including wind.-- 1980 – The first utility-scale wind farms are installed in California.-- 1981 – NASA scientists Larry Viterna and Bob Corrigan develop “The Viterna Method,” which becomes the most common method used for predicting wind turbine performance, increasing

Efficient Wave-Generated Power … Really!

Wave-generated power could be considered the Rodney Dangerfield of offshore renewable energy sources; it gets no respect. There have been a number of high-profile, expensive failures that have conspired to give the sector a poor reputation despite a number of engineering advances. A new entrant is SurfWEC offering a patented “surf-making” Wave Energy Converter which has been in development since 2007. Its developers promise it will stand out from the field and perform where others have failed. How? The SurfWEC design improves upon a generation of 'lessons learned,' and more important

Northland Signs Taiwan Offshore Power Deal

. Offshore wind has the potential to transform Taiwan’s economy and environment, creating jobs while helping to foster energy security. This project also aligns with Northland’s commitment to deliver long-term value to shareholders, while supporting the global transition to clean and green energy sources."Northland and Yushan Energy are also engaged in developing the Hai Long 2B and Hai Long 3 offshore wind projects in Taiwan. In June 2018, these projects were allocated grid capacity for connection in 2025 under Taiwan’s auction program and are expected to execute their respective

“We are moving autonomous technologies into vehicles that have always been "remotely operated" or even manned to realize more efficiency and capability.  We are really blurring the lines between "ROV" and "AUV" and minimizing the technical difference between manned and unmanned. ”

Additionally, they are looking for improved underwater positioning and through-water communications. The desire is to move toward providing a sustained presence where we can, not only, sense the environment but can affect it and react

Ørsted Tapped for Connecticut Offshore Wind Farm

Ørsted US Offshore Wind and President of Ørsted North America, said, “Offshore wind will bring long-term economic and environmental benefits to Connecticut, attract related industry and supply chain investments to the state, and support Connecticut’s transition to renewable energy sources.”Revolution Wind is part of the Deepwater Wind portfolio which Ørsted acquired in October 2018. Deepwater Wind proposed the 100MW Revolution Wind project prior to the company’s acquisition.The selection follows the approval in December by Connecticut regulators of a 20-year

Seismic From Below

.“To improve OBN survey efficiency and reduce costs, a number of surveys worldwide have been acquired using simultaneous sources. For this to be applied offshore Brazil will require either a change in the current environmental concerns regarding the proximity of seismic sources or alternative energy sources to be employed,” said Midenet. “While there have been some promising developments in this area recently, these are far from being operationally proven and thus the goal of reducing OBN costs to encourage wider application and uptake will take some time unless the environmental concerns

Roadmap for Renewable Energy

not discharge effluent into the sea. Ultimately, undersea cables are enabling the distribution of renewable energy to areas that can benefit. These projects could help to drive a global shift in the power grid, which may see an increasing number of homes and businesses make fuller use of renewable energy sources – thereby reducing their carbon footprints. The Author Jessica Williams is an analyst at S&P Global Ratings. Environmental and climate risk research focused on energy transition and storage, climate policy and ESG risk.

Tidal turbine ballast for fixed offshore tidal turbines

Tidal Turbines: Is Better Ballast the Answer?

Tidal turbine ballast might be the answer in the search for reliable and economical solutions   Alternative and in particular marine renewable energy sources have recently become very popular due to all natural disasters caused by the severe climate changes and the high levels of carbon dioxide in the atmosphere. Wind and sun possess high energy potential, but their outcome remains quite unpredictable, consequently unreliable and expensive. Opposed to that ocean power is based on natural regularities as ebb and flow tides and can be planned and controlled. This is also the reason why many big

Submarine Power Cables Protection

Submarine power cables are largely deployed in various offshore renewable energy sources such as wind, wave and tidal installations to transfer power to shore, but also in oil and gas platforms and ocean science observatories. They ensure the power supply to remote areas and by connecting regional electrical transmissions enable global energy trading.   The growing importance of the marine renewable energy sector and the word’s focus on environmental issues have made submarine power cables an infrastructure of critical importance. Most efficient and reliable installation and protection
