For Offshore Wind Farms

Woods Hole Oceanographic Institution, working with AWS Truepower, has installed the WINDCUBE vertical profiling lidar at WHOI’s Martha’s Vineyard Coastal Observatory, located 2 mi. south of Martha’s Vineyard in the Outer Continental Shelf. The Massachusetts Clean Energy Center funded the installation. Renewable NRG Systems supplied the lidar and will perform biennial maintenance services. The WINDCUBE will provide a continuous record of the wind resource across the full vertical rotor span of wind turbines used in offshore wind farms.

BOEM, MCEC Announce
Results of Two Multiyear WEAs

The U.S. Bureau of Ocean Energy Management (BOEM) and the Massachusetts Clean Energy Center announced the results of two new multiyear marine wildlife survey efforts collecting baseline biological occurrence and distribution data for whale, turtle and bird species in the Wind Energy Areas (WEAs) offshore Massachusetts and Rhode Island. The surveys found that the Massachusetts and Rhode Island WEAs avoid the high concentrations of protected species of whales, turtles and seabirds in these areas. Waters offshore Massachusetts and Rhode Island are important for many species year-round, including breeding, nonbreeding and migratory periods. Baseline knowledge of wildlife distributions and habitat use are key to making environmentally responsible decisions. These data can help identify important habitat areas, guide siting decisions for future development and inform environmental permitting requirements and mitigation efforts to minimize effects from these activities to wildlife.

Preliminary Permit for
Bourne Tidal Test Site

The Marine Renewable Energy Collaborative (MRECo) was notified by the U.S. Federal Energy Regulatory Commission that the Bourne Tidal Test Site has been approved for a preliminary permit in the Cape Cod Canal. MRECo will now move forward with additional environmental studies. Once complete, MRECo can begin the installation process, testing and evaluation of the systems, and turbine designers will be able to test their devices at the site.

FORESEA Awards 10 Ocean
Energy Tech Developers

The FORESEA (Funding Ocean Renewable Energy through Strategic European Action) Programme has awarded a Recommendation for Support to 10 ocean energy technology developers. The support will help commercialize these technologies by providing free access to open-sea test centers. FORESEA is an €11 million project to help bring offshore renewable energy technologies to market by providing free access to a network of test centers: EMEC (UK), SEM-REV (France), SmartBay (Ireland) and Stichting Tidal Testing Centre (Netherlands). Access is awarded through a series of competitive calls for application and financed by Interreg Europe. Awards were granted to: Aquantis Technology, Corpower Ocean, GEPS Techno, Laminaria, Mako Turbines, Nautricity, Pytheas Technology, QED Naval, Seacurrent, and Zyba. The second call for ocean energy applications is now open. Information can be found at www.foreseaproject.eu.

Phoenix ROV Services Support
Block Island Wind Farm

Phoenix International Holdings Inc. teamed with Ocean Tech Services (OTS) to provide ROV services in support of the Block Island Wind Farm (BIWF) installation, a 30-MW, five-turbine wind farm that is the very first offshore wind farm in the U.S. Phoenix operated an inspection-class ROV and monitored: cable touchdown on the seafloor prior to burial, cable pull-in at each offshore wind turbine platform, installation of concrete protection mats at cable crossings, and installation of cable protection ducting.

AquaHarmonics Wins
Wave Energy Prize

The U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy chose AquaHarmonics as the winner of the Wave Energy Prize, which comes with a $1.5 million grand prize. CalWave Power Technologies and Waveswing America were awarded second and third place, respectively, with $500,000 and $250,000 in cash prizes. The Wave Energy Prize aims to catalyze the development of wave energy converters to ultimately reduce the cost of wave energy.

Battery Generates Electricity
From Temp Differences

Seatrec Inc. has completed its seed round of financing to further develop the TREC Thermal RECharging Battery that generates electricity from temperature differences in the ocean. TREC is designed to power a wide range of underwater systems. Researched, prototyped and field tested by NASA’s Jet Propulsion Laboratory and licensed to Seatrec by Caltech, TREC employs a nontoxic material that can expand and contract dramatically with changes in temperature. These changes in volume are used to generate electrical power. During an 18-month sea trial in deep waters off the coast of Hawaii, a TREC-powered UUV completed more than 1,000 dives to 500 m while recording depth, ocean temperature and salinity.

O&M Provides Opportunity to
Diversify into Offshore Wind

A new report from NSRI (National Subsea Research Initiative) has identified operations and maintenance (O&M), particularly inspection, repair and maintenance (IRM) activities, as the highest potential area for U.K. subsea companies to diversify into offshore wind. The “Subsea Technological Challenges in Offshore Wind” report includes a technology roadmap with industry-driven objectives. Around 40 percent of the typical life cycle costs of offshore wind farm developments come from O&M requirements. The O&M costs for more than 5,500 turbines could be worth £2 billion per annum by 2025. Companies could break into the offshore wind market by offering services such as automated inspection, cable scour inspection, condition monitoring, remote monitoring, increased turbine access and risk-based inspection. These services could be bundled into a full life-of-field offering. Diverless solutions will also come into focus as offshore wind developments move into deeper waters.
