The timetable provided by EDF forecast that the final assembly and quayside tests of the OpenHydro machine to be installed at the Paimpol-Bréhat test site would be completed to-day.
This is the extent of the alert. To-day is D-Day-8 to get the 20% discount. With effect from 1st September only subscribers will be able to read the entire article that follows.
The machine arrived on the 18th July at DCNS in Brest. (See the previous article). EDF's objective is to install and test 4 OpenHydro sea turbines in live conditions, connecting them to a transformer on their site at Horaine. (See the article published by EDF). The first of the four ordered will be submerged off the island of Bréhat, in the department of Côtes d'Armor in Brittany in Septmber 2011. The inauguration of the demonstration farm is planned for the end of summer 2012.
This innovative project has a €24m budget... a summary will be presented at the forthcoming entretiens Science et Ethiquein Brest lthis coming 17 & 18 November. At their web site, EDF mentions the incidence of the project on the environment have been reduced or offset in respect of all the various requirements (water law, use of the marine public domain) and the Schéma de Mise en Valeur de la Mer du Trégor Goëlo. Yesterday Cécile Guérin (Radio Suisse Romande - RSR Savoirs) broadcast an interview about Charles Galland, the man in charge of hdraulic development at EDF. He gave details of the unit and its future installation, pointing out that the turbine, at 16m, is 4 times the diameter of an Airbus engine, its tripod base, the laying of the underwater cables to link with the land based transformer, and laid on both granite and mud. He talked too about the acoustic aspect possiblly having an effect on fish, but more probably on cetaceans present in the area. They have a departure point sound print that will allow them to evaluate the future situation. The marine turbine is driven by the tidal current that varies in strength, and therefore creates a changing hydraulic noise, although the OpenHydro technology has the advantage that it has no rotating axis, so no rumble.
