GIS-Based Model to Help Plan Cable Route at Dogger Bank
Offshore Marine Management (Bristol, England) announced in February that it has completed a GIS-based data study for the first stage of the Round 3 Dogger Bank offshore wind farm development, planned by Forewind (Reading, England).
The study was done by using Offshore Marine Management’s Esri GIS facilities, which developed a GIS-based cost-model tool for determining optimal interarray cable routes. This tool will be utilized by Forewind to assess routes for initial projects in its Tranche A site at Dogger Bank. The tool can be used again on future tranches in the zone.
“The team used Esri ArcGIS analysis functions to write a software tool for the cost model,” Offshore Marine survey manager Oliver Taylor said. “This tool is capable of analyzing raster data sets from multiple data sources, such as seabed sediment classifications and soil shear strengths. Ultimately, this will help Forewind to plan a cable route which offers the least cost to the installer.” For more information visit www.offshoremm.com.
PowerBuoy Completes Successful Three-Month Deployment
Ocean Power Technologies Inc.’s (Pennington, New Jersey) PowerBuoy, an autonomous wave energy device, continuously supplied more than 400 watts during its three-month deployment off the coast of New Jersey, exceeding the project’s specified 150 watts, the company announced in February.
The PowerBuoy was deployed under a contract from the U.S. Navy’s Littoral Expeditionary Autonomous PowerBuoy program to power the Navy’s radar and communications payload. Moored at 37 meters’ depth, the PowerBuoy produced a peak sustained electrical power of 1,500 watts and supported the Navy’s 150-watt payload throughout the entire deployment, Ocean Power Technologies said.
In August, the PowerBuoy had been in the path of Hurricane Irene, which hit the New Jersey coastline. The device emerged from the two-day storm undamaged, having withstood wave heights of more than 16 meters. During the storm, it continually produced and delivered power as well as dissipated the high amounts of excess energy in accordance with its internal protection systems.

Wind Energy Area Identified Off Massachusetts, Rhode Island
The Bureau of Ocean Energy Management (BOEM) identified in February a potential wind energy area off the coasts of Rhode Island and Massachusetts, comprising approximately 164,750 acres that the states had designated as a mutual-interest area in 2010.
Excluded from the wind energy area are grounds important to commercial fishing. BOEM will also take the critically endangered North Atlantic right whale, vessel traffic and visual and cultural resources into consideration during its environmental assessment of the area.
BOEM requested public comment on site conditions and other existing uses of the area as part of the potential leasing and development authorization process. This move followed U.S. President Barack Obama’s State of the Union address, in which he called for an “all of the above” energy strategy, and is part of the Department of the Interior’s Smart from the Start program.
“We will follow marine spatial planning principles as we continue to gather information and coordinate with other OCS users throughout the leasing process,” BOEM director Tommy P. Beaudreau said. For more information visit www.boem.gov.
Hydraulic Yoke Completes Tests At Offshore Wind Farm
Fyns Kran Udstyr A/S (Odense, Denmark) has tested its hydraulic lifting yoke in London Array, offshore England’s east coast. The yoke cuts down on time and cost of lifting and enhances security, the company said in February. Germanischer Lloyd (Hamburg, Germany) approved the yoke.
During the test, the hydraulic yoke lifted 370-ton offshore wind-turbine foundation parts, called transition pieces, from dock to vessel, then from vessel to offshore monopolies. The yoke decreased lifting preparation time to 10 minutes from the former norm of one hour and required only one person to supervise the work, Fyns Kran Udstyr said. The level placement of the transition pieces on the vessel and at sea minimized the risk of tilting.
The yoke will enable operations even during storms, when short breaks from challenging weather can be used to perform quick lifting. The reduced time required for the vessel and staff at the turbine site should result in less costly operations, the company said. For more information visit www.fyns-kran.dk.
UK Consortium to Establish Offshore Green Energy Center
The U.K. Technology Strategy Board announced in February that it has chosen a U.K.-based consortium to set up the Offshore Renewable Energy Catapult, with headquarters in Glasgow, Scotland. The center will be established by the Carbon Trust (London, England), National Renewable Energy Centre (Blythe, England) and Ocean Energy Innovation, which includes Scottish Power Renewables, SSE and the European Marine Energy Centre.
The Glasgow, Scotland, headquarters will be located in the International Technology and Renewable Energy Zone.
The operational center will be in Northumberland and will receive up to £10 million a year over five years from the U.K.’s Technology Strategy Board, totaling £50 million.
The center will focus on offshore wind, tidal and wave power technologies, help U.K. businesses bring and export new products to market and try to set up a sustainable supply chain for the U.K.’s offshore wind sector. In addition, the center will create and maintain strong relationships with what the U.K. Technology Strategy Board calls centers of excellence, such as the Wave Hub, a grid-connected offshore testing facility for wave-energy technologies, and an upcoming marine energy park in southwest England.
The Catapult center, scheduled to open in the summer, will strengthen the U.K.’s position in the wind, tidal and wave energy global market, expected to exceed £64 billion by 2050, by helping gain 12 percent of the established offshore wind industry and 15 percent of tidal and wave energy market share opportunity.
