Fugro Undertakes Navitus Bay Geophysical Survey
Fugro (Leidschendam, Netherlands) has successfully performed a detailed geophysical survey of Navitus Bay for Eneco Round 3 Development Ltd. (Rotterdam, Netherlands), the company said in March. Navitus Bay is to the west of the Isle of Wight and lies within Zone 7 of the Crown Estate’s Round 3 U.K. offshore wind farm zones.
The aim of the survey, which covered more than 200 square kilometers and took around one month to execute, was to acquire data to carry out front-end engineering and design studies, and to gain an understanding of the zone’s geology and geomorphology. Fugro was tasked with acquiring survey data to support the environmental processes and the detailed design and installation of the wind turbine foundations and export cables.
The geophysical survey was on the main wind farm area, the export cable routes from the wind farm to the U.K. mainland and a met mast location. Various sensors and geophysical techniques were used for the survey including single- and multibeam echosounder, high-resolution side scan sonar, sub-bottom profiler, magnetometer and ultrahigh-resolution multichannel seismic. The integrated survey report provided imagery of the seafloor and a geological model of the site.
GL Garrad Hassan Wins Two DOE Grants
GL Garrad Hassan (Bristol, England) has been awarded grants by the U.S. Department of Energy (DOE) of $500,000 and $200,000 to fund two studies to identify optimal strategies for the installation, operation and maintenance of offshore wind farms, and to assess the readiness of U.S. ports to meet the needs of the industry.
The grants are part of a DOE offshore wind initiative that has awarded more than $43 million for projects aiming to accelerate developments, lower costs and shorten the timeline for deploying offshore wind energy systems.
GL Garrad Hassan will analyze existing and future needs of the U.S. offshore wind industry for port facilities by examining the suitability of ports to meet the technical requirements of the industry for the assembly, construction and operational staging of offshore projects. This study will also identify gaps in the capability of individual ports to service regional offshore projects and identify potential investment opportunities. Port infrastructure will have to dramatically expand to meet renewable energy generation policy targets. A detailed review and modeling program will assess the costs of and identify approaches to offshore installation, and operations and maintenance for project conditions.
In addition to the final reports of these studies, GL Garrad Hassan will provide the results to stakeholders as stand-alone analysis tools for assessing the capacities of individual projects. Users will be able to examine port infrastructure against set offshore wind farm development criteria and run their own cost-of-energy analyses for installation and operation.
Fundy Tidal Receives COMFIT Approvals for Tidal Energy
Fundy Tidal Inc. (Westport, Canada) received two more Community Feed-In Tariff (COMFIT) approvals in April for a 500-kilowatt project in Grand Passage and a 100-kilowatt project in Cape Breton located at Barra Strait.
These projects are in addition to Fundy Tidal Inc.’s Petit Passage and Digby Gut projects that received COMFIT approval during the winter. The COMFIT approval guarantees a rate of 65.2 cents per kilowatt of electricity produced and will help ensure these projects are financially viable.
Dana Morin of Fundy Tidal explained, “Fundy Tidal’s aim has been to establish Brier and Long islands as the focal point of small-scale tidal development and as an important hub of [research and development] activities to inform deployments at our other sites. With four COMFIT approvals in hand, there is only one other 500 kilowatt project in Cape Breton to complete our portfolio of 3.55 megawatt.”
First Wave Energy Device Installed at Falmouth Test Site
Fred Olsen’s (West Ipswich, Australia) Bolt Lifesaver wave energy converter is being tested offshore Falmouth Bay at FaB Test, part of the South West Marine Energy Park. The device was manufactured at A&P Falmouth (Falmouth, England). It will potentially be deployed in more energetic offshore waters at the grid connected Wave Hub site off the Cornish coast.
Wave and tidal energy has the potential to generate up to 27 gigawatts of power in the U.K. by 2050. The FaB Test site, which is not connected to the grid, gives developers the chance to test devices in a nearshore environment for structural integrity, response behavior, mooring/umbilical behavior, subsea components, monitoring systems and deployment procedures.
French Consortium Awarded 500-Megawatt Wind Project
The French government will award the Iberdrola-Eole-RES consortium exclusive rights to develop a 500-megawatt offshore wind project offshore St.-Brieuc, France, the consortium announced in April.
The offshore wind farm will be built approximately 20 kilometers off the coast of St.-Brieuc Bay in the French administrative area of Côtes d’Armor by the consortium led by Iberdrola (Bilbao, Spain) and EoleRES (Avignon, France) and including Paris, France-based partners Areva, Technip and Neoen Marine. A joint venture company, Ailes Marines (Paris) has been set up to manage the project and subsequent operation of the site. The project covers a total area of 80 kilometers and comprises 100 wind turbines of 5-megawatt capacity each.
Over the next 18 months, the consortium will analyze the site’s technical and environmental risks to conduct a feasibility study. In July 2011, France launched the first round of a tender process aimed at installing 3,000-megawatts of offshore wind capacity, which involves the construction of around 600 wind turbines by 2018.
