How Ice Could Impact Subsea Cables and the Great Lakes’ Offshore Wind Success

Ice hasn’t necessarily put a chill on the development of offshore wind in the Great Lakes of North America, but it does pose a significant challenge — both in the design of offshore wind turbines and the maintenance of subsea power transmission cables. Winter is a wildcard for the Great Lakes because the offshore wind… Read More

The Cable Challenges of Saltwater vs. Freshwater for Offshore Wind Projects

The corrosive effects of saltwater on subsea cables and accessories are well known. Freshwater doesn’t have quite the same impact, but it still raises a range of issues for offshore wind developers. The saltwater vs. freshwater comparisons are becoming more relevant as offshore windfarm projects along the Great Lakes of North America — the largest… Read More

5 Complications for Tidal and Wave Energy Devices

Converting the immense power of our oceans into reliable electricity to light our cities, fuel our travels, and make our homes habitable is one of the great engineering challenges of our time. A beguiling array of wave-energy devices, tidal turbines, and coastal-barrage proposals are in the works to meet this challenge, but the prospect of… Read More

Innovations Shrink Offshore Wind Timelines

There’s nothing quick about developing an offshore wind farm. It takes years of site selection, political and financial wrangling, environmental reviews, and careful construction to make it all happen. But those timelines could be getting shorter thanks to developments in the European offshore wind market. An article in IEEE Spectrum in June 2017 noted a… Read More

Why the U.S. Ocean Energy Market Faces One Big Challenge that Europe Doesn’t

On average, European offshore wind turbines stand in 29 meters (95 feet) of water about 44 kilometers (27 miles) from the shore, WindEurope reports. These two stats underscore one of the key reasons why offshore wind in U.S. waters is a flyspeck compared to the installed capacity of European wind farms. The first U.S. offshore… Read More

Universities’ Focus on Underwater Engineering is a Welcome Development in Offshore Wind

It’s impossible to separate underwater engineering from the research emerging from major universities. Indeed, this engineering discipline is proving central to the evolution of offshore wind power in the United States. That’s especially true at three Ohio universities, where researchers are building a scientific and engineering foundation for the development of offshore wind in the… Read More

Looking to Asia for Offshore Wind Opportunities

While Europe gets all the credit for the rise of efficient offshore wind farms, there’s a lot of potential brewing in Asia — especially in countries that already have active land-based wind power. China has already built so many inland wind farms on land that it has more capacity than its interior population can use… Read More

Artificial Island Sparks Innovation In Wind Energy

A shallow patch of the North Sea is the site of an intriguing plan to reduce the cost and complexity of offshore wind farms. Announced in March 2017, the plan calls for the construction of an artificial island to form the hub of a massive network of wind turbines. One key advantage of a hub… Read More

America’s First Offshore Wind Farm Is Finally Ready for Prime Time

May 1, 2017, is the scheduled cutover date for the Block Island Wind Farm, whose five turbines will begin transmitting up to 30 megawatts of wind-generated power to the mainland power grid. The towers are arranged near Block Island, a tourist destination off the coast of Rhode Island that has about a thousand permanent residents…. Read More

Analytics: Measurement Means Everything to the Future of Offshore Wind

Server farms are increasingly crucial to the success of wind farms — offshore and otherwise. Data scientists armed with cloud-hosted analytics applications and tower-based telemetry can track every minute in the life of a wind turbine. This is especially crucial in the rugged offshore environment, where storms, corrosion, sea life and everyday wear and tear… Read More
