Underwater noise is a big concern when installing offshore wind farms. For example, pile driving to secure offshore foundations transmits loud booms through the water and for many miles. The full impact of construction noise on marine life is yet unknown, but potentially dangerous to certain species of sea life. So what if it was possible to reduce offshore construction noise at its source?

A consortium including Siemens GamesaUniversal Foundation, Aalborg University, Fred. Olsen Windcarrier and Offshoreenergy.dk has been awarded 3.8m EUR by the Energy Technology Development and Demonstration Programme (EUDP) via the Danish Ministry of Energy, Utilities, and Climate. The partnership seeks to demonstrate how an industrialized suction-bucket concept can slash the installation costs of offshore wind foundations.

Magellan Wind and Copenhagen Infrastructure Partners (CIP) have joined forces to embark upon an early-stage development portfolio of floating offshore wind projects off the California coast and other areas of the United States. Magellan will contribute knowledge of U.S. leasing, permitting, offtake, transmission, and interconnection, and CIP will provide project design, engineering, finance, construction, and operations.

But it is not its height that makes this turbine special. It’s one of five emerging from the sea as part of Hywind Scotland – the world’s first floating windfarm.

“With floating wind, we’re trying to access deeper waters, particularly where there’s quite high wind speeds as wind is the fuel of the industry,” explains Rhodri James, a manager at the Carbon Trust.

New Concept for Offshore Wind Turbine Jackets

A new concept for a one-hundred-year minimum life concrete jacket foundation has been designed for offshore wind turbines.

Andy Filak, Principal of AMF Concepts, says that one of the major hurdles to the development of offshore wind farms has been the development of reliable foundation systems with long life and ease of installation in deepwater. Current concrete technology is not robust enough for the long-term exposure that is experienced in an ocean wind farm, he says, and steel technologies require complicated shoreside construction and at-sea installation involving multiple large crane barges and anchor handling tugs.

ABS has completed a design review for the University of Maine-developed VolturnUS foundation for floating offshore wind turbines.

The patented VolturnUS, developed by the Advanced Structures and Composites Center at the University of Maine (UMaine), is based on a concrete four-column semi-submersible.

Comparing floating foundations for offshore wind farms

Editor’s note: An earlier version of the Ocean Going Deck Barge and its operation is described here: https://goo.gl/Sz04s9  AMF Concepts has revised its design to use a catamaran for the barge to simplify buoy and WTG construction and deployment along with greater stability.

 U.S. deepwater offshore floating wind turbine foundation platforms are taking too long to develop. We need them now. One design is readily available.

At present, 58% of the U.S. population lives in coastal areas. The National Renewable Energy Laboratory estimates there is potential for 4,233 GW of clean energy off the coast mostly in deep water. The figure is four times the capacity of the U.S. electric grid. The first fixed-bottom offshore wind farm in U.S. waters is now capturing this clean energy off the coast of Rhode Island. This project is now part of the 50 offshore wind farms operating worldwide.
