Technology • Regulation • Current Projects Ocean Energy FERC, U.S. Coast Guard sign agreement to coordinate development of hydrokinetic projects The Federal Energy Regulatory Commission (FERC) and the U.S. Coast Guard within the U.S. Department of Homeland Security have signed a Memorandum of Understanding (MOU) to cooper-ate with each other on the development of hydroki-netic projects. These projects generate power from waves, tides, ocean currents, and the flow of rivers. The MOU will advance interagency cooper-ation in protecting navigation safety, maritime security, and environmental resources when con-sidering license proposals for hydrokinetic energy development. “Hydrokinetic development is an up-and-coming resource, and this MOU provides valu-able coordination between FERC and the Coast Guard to ensure an efficient process while protect-ing valuable environmental resources,” comment-ed FERC Chairman Jon Wellinghoff. “I want to thank the Coast Guard for their willingness to move forward with the important agreement.” Specifically, the MOU will improve the ability of the agencies to establish a joint timetable, identify criti-cal issues early, acquire and share information effi-ciently, and collaborate on analysis. ABB leads $12 million investment in tidal power leader Scotrenewables ABB, the global power and automation technology group, has led a $12 million investment in Scotrenewables Tidal Power, a provider of tidal turbine systems, to support the rollout of a new hydrokinetic device and to expand ABB’s renew-able energy assets. ABB’s participation was made through its venture capital unit, ABB Technology Ventures (ATV), which invests in early and growth stage companies with technologies of strategic importance to the industries it serves. The invest-ment round included participation from existing strategic investors Total New Energies, a unit of oil major Total, and Fred. Olsen, the Norwegian mar-itime conglomerate, through its associated Bonheur and Ganger Rolf holding companies. The funding is being used specifically to roll out a larg-er and more advanced tidal energy conversion system known as the SR2000. The floating 2-MW turbine includes a number of innovations to deliver simplicity, low mass, rapid connection/disconnec-tion, and heightened survivability. Scheduled for completion next year, it will be the first of a number of commercial units installed in the Lashy Sound tidal demonstrator project in Orkney, where Scotrenewables is based. London Array – the world’s largest operational offshore wind farm On 7 March 2013, London Array officially became the world’s largest operational offshore wind farm. In total, 141 of the 175 3.6 MW Siemens wind tur-bines are now able to generate 507 MW of energy for UK homes and businesses. This is a significant achievement for everyone involved in the project that generated first power in October 2012. The final turbine was installed in December 2012, and the project is expected to be fully operational in the spring. London Array is arguably the most widely known UK offshore wind farm. Its sheer scale and proximity to Greater London mean it is often referred to by politicians and in the press.

DONG Energy on track to complete installation of 111 turbines

DONG Energy is exactly halfway in the Danish wind turbine installation project at Anholt Offshore Wind Farm and expects the erection of all 111 wind turbines to be com- pleted and the wind turbines to be operational by summer, as planned.

Of the 55 turbines already installed, 48 have been energized and 33 have produced power.

Up to four installation vessels have worked on installation together. They are Sea Jack, Sea Installer, Sea Power, and Sea Worker.

Turbine installations are dependent on weather conditions, and the harsh weather this winter has meant that, for several periods, it has not been possible to install wind turbines.

Wind and waves have reduced installation speed due to technical limitations of the installation vessels, but all weather windows enabling installation have been used optimally.

Wind turbine installation activities commenced on 1 September 2012, and the first wind turbine was erected on 3 September. It was this very wind turbine that produced the first power generated by Anholt Offshore Wind Farm.

GDF Suez signs an industrial partnership agreement for its tidal power project at Raz Blanchard (Lower-Normandy)

GDF Suez has signed a partnership agreement with Cofely Endel, its subsidiary that specializes in industrial maintenance; the hydro turbine equipment design company Voith Hydro; the French shipbuilder Constructions Mécaniques de Normandie (CMN); and ACE1. Through this partnership, GDF Suez reaffirms its marine energy ambitions And it commitment, working with indus- trial companies with complementary expertise and local interests to develop a pilot plant at Raz Blanchard as early as 2016.

Through this industrial partnership agreement, GDF Suez and its partners will be able to combine their know-how and collaborate through the construction, assembly, and maintenance phases of the future Raz Blanchard pilot plant. The Group selected the Voith Hydro- designed “HyTide” marine technology to outfit all or part of this pilot plant.

The partnership is also made up of ACE and CMN, whose location at the port of Cherbourg is an advantage for carrying out these operations, which, for the most part, must be performed near the site of immersion of the marine turbines. Cofely Endel, also based at Cherbourg, will provide its industrial maintenance skills and technical project management expertise for this type of enterprise.

The aim of GDF SUEZ is to contribute to creating an industrial marine current sector in France and develop a project that respects the local environment. Therefore, the Group works with maritime and administrative authorities, not-for-profit organizations, and fisher- men to accommodate local economic activities and the particularities of the site. During the summer of 2012, the Group also embarked on a thorough off- shore campaign at Raz Blanchard of measures, enabling it to improve its knowl- edge of the site, particularly seabed char- acteristics, water depths and currents, and the makeup of marine sediments.

Mojo Maritime launches HiFlo-4 to unlock tidal energy

Mojo Maritime revealed plans for its patented development of the HiFlo-4 Installation Vessel (HF4) at the Renewable UK 2013 Wave and Tidal Event in London. HiFlo-4 is a high-performance vessel built around installation processes and the demanding environment experienced in tidal races such as The Pentland Firth. The launch focused on the vessel’s capability; the economic model and the commercial development of the project is focused on safe, economic industrialization of tidal energy.

The vessel is designed to operate using dynamic positioning in currents up to 10 kts, allowing a high degree of accessibility and improved productivity During the construction phases of tidal energy farms—indeed, the modeling carried out demonstrates that the vessel is capable of complete installation and hook up of 50 turbines per year, equating to 70 MW of installed capacity from a single vessel.

The vessel is a twin-hull vessel powered by four Voith Schneider propellers (VSP), with a high degree of attention on the hydrodynamics of the twin hulls coupled with the VSPs. The vessel is capable of installing foundations, cables, subsea connectors, and turbines in a wide range of conditions. The design has been inspired by Mojo’s work with Bauer on their award-winning BSD-3000 Subsea Drill and provides a safe and economic platform for installing drilled foundations.

MacArtney named partner in major Pacific WindFloat project

Recently, renewable energy technology developer Principle Power was awarded a Department of Energy grant worth $4 million and up to $47 million in total funding to support its WindFloat Pacific Demonstration Project.

Principle Power has announced the list of official project partners, all marked to deliver an essential contribution to the WindFloat project. MacArtney Underwater Technology is proud and pleased to feature on this list and to be a part of such a promising and large-scale project.

The list of project partners also include: Siemens Wind Power, Houston Offshore Engineering, the Pacific Northwest National Laboratory, the National Renewable Energy Laboratory, RPS Evan Hamilton, Forristal Ocean Engineering, the American Bureau of Shipping, and Det Norske Veritas.

The WindFloat Pacific Demonstration Project is centered around a 30-MW floating offshore wind farm, planned to be located approxi- mately 25 km west of Oregon’s Port of Coos Bay.

To date, due to technology and pro- ject economics, offshore wind farm locations have been limited to environ- mentally and stakeholder sensitive shallow inshore waters. However, based on a patented floating foundation for off- shore wind turbines, the innovative features of the WindFloat allow turbines to be placed at deepwater locations, out of sight from shore where the wind is stronger and more consistent.

The WindFloat offers considerable economical advantages over traditional offshore wind solutions, since the entire turbine and floating foundation is built and assembled on shore and installed using conventional tug vessels. This way, the WindFloat is also a more costeffective, simpler, and less risky approach to offshore wind development. A prototype of the WindFloat system has been operating successfully off the coast of Portugal since October 2011. This installation marks the first multimegawatt offshore wind turbine to be installed without the use of any heavylift offshore vessels.
