Scotrenewables Reaches
Full-Rated Power at EMEC

The world’s most powerful tidal turbine, developed and manufactured by Scottish engineering company Scotrenewables Tidal Power Ltd., has reached full-rated power at the European Marine Energy Centre (EMEC) in Orkney, Scotland.

After undergoing grid-connected commissioning works prior to Christmas last year, the SR2000 was reconnected to its subsea cable in a low-cost connection operation that took under an hour.

All offshore operations have been delivered with small crew transfer vessels or locally based workboats.

Following energization, the 500-tonne floating tidal turbine commenced generation and power export to the local Orkney grid. Since then the turbine has been undergoing a phased testing program leading to the achievement of a full 2-MW-rated export capacity. This deployment is already feeding into design optimizations that are being made under the company’s commercialization project, FloTEC, which will see an even lower-cost SR2000 model rolled out as a commercial offering in 2018.

BOURBON Chosen for Wind
Turbine Mooring Installation

BOURBON has been awarded a contract for the mooring installation of the first floating wind turbine in France at the experimental test site of SEM-REV managed by Ecole Centrale de Nantes (ECN), in the context of the European project FLOATGEN.

The mooring installation will take place summer 2017 based on a method jointly established by BOURBON and Ideol’s engineering teams in collaboration with the Ecole Centrale de Nantes.

The wind turbine will be installed near Le Croisic, France, by the end of the year.

BOURBON’s Subsea Services team will be responsible for the project management, mooring installation and engineering. An anchor handling tug supply vessel and ROVs will be used for the pre-tensioning of the mooring system.

Two Projects to Develop
Monitoring Tech for Tidal

Industry and academic researchers will join forces to collaborate on two projects developing new environmental monitoring technologies for tidal energy applications. The projects were selected for funding through a joint research competition sponsored by the Offshore Energy Research Association of Nova Scotia (OERA), the Nova Scotia Department of Energy and INNOVACORP.

The project winners are Open Seas Instrumentation Inc. (OSI) and JASCO Applied Sciences. Each project introduces an innovative approach to monitoring marine life near a tidal turbine. The research results will lead to greater understanding of the complex relationships between tidal energy development and the biological and physical ocean environment.

The Open Seas project focuses on the redesign of a subsea platform for monitoring movement and behavior of marine life close to the turbine. 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 acoustically 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 developer 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 combined 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. waters today range between 3.0 and 3.6 MW, with a small number generating up to 7 MW.

Building fewer, higher capacity turbines saves money because less maintenance and fewer foundations, transition pieces and connection cables to nearby substations are required.

The news follows the announcement that the U.K. renewable energy sector experienced its best ever quarter 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 energy over the quarter, an increase of 10 percent from a year earlier. On 57 out of the 90 days in the quarter, wind produced 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 transport of array cables and export cables from the seabed onto the substation decks of the Hornsea Project One offshore 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 turbines through specialized submarine cables.

The scope of supply of this DONG Energy order covers three MacArtney 160-kN electrical cable pulling winches, including three comprehensive spare parts packages per winch.

MacArtney will also supply an integrated data logger and Dyneema ropes.

Damen Launches RSV 3315
For Offshore Wind, Tidal

Damen has launched the Renewables 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 wheelhouse 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.
