Offshore Wind: Regulatory “Takes” – Take a Close Look

public comments, on a proposed “incidental harassment authorization” (IHA).  An IHA is a legal and enforceable document presenting the terms and conditions with which a company must adhere in order to protect wildlife.  In this case, the draft IHA was for Vineyard Wind, the wind energy company ready to start construction on an 800 MW offshore wind farm in the Atlantic, covering about 675 square kilometers, starting 14 miles from the coastline of Martha’s Vineyard.  This would be the first large-scale, ocean-based US wind energy project, consisting of up to 100 wind

New Autonomous Vehicle for Offshore Wind Surveys

A new autonomous sailing platform aims make the collection of offshore wind energy data easier, faster, cleaner and more cost efficient.The 16-foot wind- and solar-powered Datamaran, launched recently by Norwegian energy company Equinor and US technology firm Autonomous Marine Systems Inc. (AMS), carries a LiDAR (Light Detection and Ranging, a well-established technology used to record wind characteristics hundreds of feet above the surface) to gather data on wind and weather conditions at offshore lease areas for the development of wind energy projects.Typically, this data has been collected by a

;s interpretation is incorrect.  Neither the U.S. citizen manning requirement nor the exemption procedure for this requirement limits its mandate to mineral activities.  Indeed, the specific authorization that gives BOEM the authority to approve the development and construction of a wind energy project on the OCS, is authorized pursuant to a 2005 amendment to OCSLA, to specifically expand this authority beyond the production of oil and gas on the OCS.  Similarly, OCSLA also authorizes the Coast Guard to regulate the health and safety of workers and facilities offshore without distinguish

SGRE Bags Largest U.S. OWP Order

The Spanish wind energy giant Siemens Gamesa Renewable Energy (SGRE) has received an order for 1,714 MW from Orsted and Eversource.Encompassing three offshore wind power projects, the signed conditional contract is the largest U.S. offshore wind power (OWP) order to date, it said in a press release.According to SGRE, the order encompasses the supply, delivery, and installation of SG 8.0-167 DD wind turbines including service agreements in federal waters off the northeastern coast of the U.S. All deliveries are subject to Ørsted and Eversource’s final investment decision.Siemens Gamesa has

of the interior, leases areas of the outer Continental Shelf (OCS) to developers, and the states are responsible for setting terms for the wind to be brought into the state power grids and ultimately sold to consumers. Winds blow the strongest farther from shore —hence the rush to lease Wind Energy Areas (WEAs) on the OCS. These locations also have the advantage of the turbines not being seen by local beachgoers.To date, the Bureau of Ocean Energy Management (BOEM), part of the Interior Department, has awarded 16 leases to a variety of U.S. and European developers. And more leases are due

New Tech for Wind Blade Inspections

Drones and crawling robots outfitted with special scanning technology could help wind blades stay in service longer, which may help lower the cost of wind energy at a time when blades are getting bigger, pricier and harder to transport, Sandia National Laboratories researchers say.As part of the Department of Energy’s Blade Reliability Collaborative work, funded by the Wind Energy Technologies Office, Sandia researchers partnered with energy businesses to develop machines that noninvasively inspect wind blades for hidden damage while being faster and more detailed than traditional inspections

Offshore Wind – A Brief History

;Comparably, offshore wind is a newbie (okay, not counting wind power for ships and boats).  The first commercial offshore windfarm was built in 1991, in Denmark.  The first US project at Block Island, RI, in 2016!To set a timeline within a modern context this review draws on a fascinating wind energy history developed by the US Department of Energy.  On the landside, DOE’s history starts in 1850 when the US Wind Engine Company was established by Daniel Halladay and John Burnham.In 1890, steel windmill blades were invented, leading to the development of an iconic western symbol.Important

Danish. Their Chinese plants produce components for Chinese land-based wind turbines. The hope is to also get them buying drives for wind-service vessels and offshore wind turbines.“The Chinese move fast to adopt new technology,” Parpala asserts, a confident nod to ramping up the Chinese wind energy value chain. “Since the start of our company in 2006, we have delivered 6,000 converters in China for onshore turbines. One of our key Chinese customers also has our converters offshore,” he says, adding, “but we have not yet produced any equipment for marine.”The Switch

The wind turbines installed for Hollandse Kust in 2022 will not be the same as those being made now. With our international experience in wind energy, we can properly estimate these developments and ensure the infrastructure is flexible and suitable for newer technology," Marchand said.Hollandse Kust Zuid 1 & 2 will make a significant contribution to the Dutch ambition of having 4,500 megawatts of installed capacity offshore by 2023
