marinerenewables Offshore Wind Rules Set New Standard Lloyd's Register (London, England) released new rules, class notation and guidance notes for wind turbine installation, maintenance vessels and liftboats. The new rules form part of the wider Mobile Offshore Unit Rule set 2013 launched in June for vessels engaged in installation or maintenance activities relating to offshore wind turbines. It covers a number of unit types, as well as liftboats. Vessels that comply with the requirements of the new rules will be eligible for a new classifcation notation, MainWIND. The release of the rules and guidance notes coincides with reports that operators are facing an incremental rise in the cost of constructing offshore wind assets. FoundOcean to Pile Grout Wind Turbine Foundation FoundOcean (Marlow, England) has a contract from Graham (Calgary, Canada) to pile grout the foundation for the world's largest offshore wind turbine, developed by Samsung Heavy Industries (Seoul, South Korea), in Fife, Scotland. This will be the frst 7-megawatt turbine to be installed. Each blade measures more than 80 meters long. The project is part of the Fife Energy Park development. FoundOcean will complete the project in two phases using the exagrout material Masterfow 9500, from BASF (Ludwigshafen, Germany). FoundOcean will frst grout four piles into approximately 30-meterdeep, predrilled rock sockets. The second stage involves grouting the annuli between the jacket's stab in legs and piles, forming the connection. More than 500 jobs could be created in Fife through the £100 million project to develop the turbine, Scotland's Minister for Energy, Enterprise and Tourism Fergus Ewing said. A walkway is being constructed from the shore to the turbine foundation, and FoundOcean will also grout this into place using conventional pilegrouting techniques. All grout mixing will take place onshore with grout 60 st / July 2013 pumped directly to the jacket's primary input 35 meters offshore. Interior Announces Energy Lease Sale As part of U.S. President Barack Obama's Administration's all-of-theabove energy strategy to continue to expand domestic energy production, the Bureau of Ocean Energy Management (BOEM) will hold a competitive lease sale for renewable energy on the U.S. Outer Continental Shelf (OCS). The auction, scheduled to take place on July 31, will offer 164,750 acres offshore Rhode Island and Massachusetts for commercial wind energy leasing. Domestic oil and gas production has been growing. Combined with recent declines in oil consumption, foreign oil imports now account for less than 40 percent of the oil consumed in America. The wind energy area offshore Rhode Island and Massachusetts covers about 164,750 acres and is located 9.2 nautical miles south of the Rhode Island coastline. BOEM will auction the area as two leases. The North Lease Area consists of about 97,500 acres, and the South Lease Area covers about 67,250 acres. Together, these areas have the capacity to support enough electricity to power more than 1 million homes. Aquamarine Power Approved for Energy Farm Aquamarine Power (Edinburgh, Scotland) received full consent from the Scottish government for a 40-megawatt wave farm off the northwest coast of Lewis, Scotland. The green light means that the company will be able to begin installing its Oyster wave energy machines at the site in the next few years, after the necessary grid infrastructure has been put in place. Between 40 and 50 Oyster devices will be deployed along the coast at Lag na Greine, Scotland. Once complete, the farm will have the capacity to power nearly 30,000 homes. The local council approved planning for the onshore hydroelectric power plant last year, which will be connected to the Oyster wave energy farm. Aquamarine Power is testing its second full-scale wave machine, the Oyster 800, at the European Marine Energy Centre in Orkney, Scotland, and producing electrical power to the grid. Spindrift Energy to Deploy Wave Power Prototype Spindrift Energy (Simi Valley, California) has started machining components for a wave power-generating prototype. To fulfll its Energy Innovation Small Grant (EISG) from the California Energy Commission (CEC), Spindrift Energy will deploy a prototype device in the ocean waters off Southern California this year. A report evaluating the prototype's sea test for the EISG and CEC will be produced at the conclusion of the grant period in December. Spindrift's prototype will generate electricity for measurement and analysis purposes and could act as a catalyst for the near-term installation of largescale devices capable of transmitting electricity to consumers. PlanetSolar Begins Expedition On the Gulf Stream The MS Tûranor PlanetSolar departed from the French West Indies on May 23 and reached the shores of the United States on June 1. The ship will be dedicated to science as part of an expedition to study the Gulf Stream, a regulator of European and North American climates. The solar boat will serve a team of researchers from the University of Geneva. Through the month of August, the interdisciplinary team of scientists will travel over 8,000 kilometers along the Gulf Stream, between Miami, Florida, and Bergen, Norway. During the trip, researchers will collect scientifc data from the air and water to better understand interactions between the ocean and the atmosphere, as well as the role of the interactions in climate change. Because the MS Tûranor operates without pollution emission, the atmospheric measurements will not be distorted by residues associated with fuel combustion. Related educational activities and resources have been designed to make young people aware of climate change and its impact. n
