The JASCO project will develop a long- term monitoring program to measure how sound propagates in turbulent waters to better understand how these conditions affect the ability to acousti- cally detect marine life. 8-MW Wind Turbines Installed in UK The 258-MW Burbo Bank extension project includes 32 turbines, which stand at 192 m high. Danish wind de- veloper DONG Energy has completed the installation of 32 192-m-tall wind turbines in the Liverpool Bay, the UN Climate Action Programme reported. The 8-MW turbines will have a com- bined capacity of 258 MW, enough energy to power more than 230,000 homes. The Burbo Bank Extension is the first time 8-MW turbines have been commercially used anywhere in the world. The majority of turbines in U.K. wa- ters today range between 3.0 and 3.6 MW, with a small number generating up to 7 MW. Building fewer, higher capacity tur- bines saves money because less main- tenance and fewer foundations, transi- tion pieces and connection cables to nearby substations are required. The news follows the announce- ment that the U.K. renewable energy sector experienced its best ever quar- ter at the beginning of the year. Wind farms in the U.K. enjoyed their highest ever quarterly output, generating 11.3 terawatt hours (TWh) of renewable en- ergy over the quarter, an increase of 10 percent from a year earlier. On 57 out of the 90 days in the quarter, wind pro- duced more electricity than coal. According to RenewableUK, the U.K. is Europe's windiest country and could power itself several times over with wind. MacArtney Winches for Hornsea Project One Wind Farm MacArtney will ensure safe trans- port of array cables and export cables from the seabed onto the substation decks of the Hornsea Project One off- shore wind farm, located in the North Sea 14 km off the Danish west coast. The wind farm is equipped with three offshore substations that collect and export the power generated by tur- bines through specialized submarine cables. The scope of supply of this DONG Energy order covers three MacArtney 160-kN electrical cable pulling winch- es, including three comprehensive spare parts packages per winch. MacArtney will also supply an in- tegrated data logger and Dyneema ropes. Damen Launches RSV 3315 For Offshore Wind, Tidal Damen has launched the Renew- ables Service Vessel (RSV) 3315, a new type that has been developed in close cooperation with the Scottish company Delta Marine. The first in the new series was officially christened Voe Vanguard at Damen Shipyards Hardinxveld. Just a week later, the vessel was off to its first offshore wind farm, the Walney Extension project. The Damen RSV 3315 is based on the Multicat design, with the wheel- house moved forward and the aft deck open. It has a DP2 capability and is suitable for offshore wind and tidal projects, where it can stay in position using DP in strong currents. ST
