Local firm powers ahead with turbine project
Orkney company Scotrenewables Tidal Power has awarded a key fabrication contract for the superstructure of its next generation tidal turbine.
The 2 megawatt (MW) SR2000 turbine will be the culmination of more than 12 years of research, design and testing at increasing scales by Scotrenewables.
The turbine will be demonstrated at the European Marine Energy Centre in Orkney from 2015 ahead of sales to tidal array developers. The company says that once launched next year, it will be the most powerful tidal turbine in the world to date.
The 64 metre floating hull will be constructed by Gray Fabrication based in Cupar, Fife, and will form the structural backbone of the SR2000.
The floating turbine, which is designed specifically to minimise installation and maintenance costs, features a radically different design from seabed tidal turbines.
The floating hull will incorporate two 1MW rotors mounted on retractable legs. This allows the draught of the turbine to be reduced for towing in and out of shallow harbours, with marine operations carried out by small low-cost vessels.
The hull sections will also house the turbine’s electrical and control equipment, allowing direct access to the turbine for maintenance while at sea.
This is another core design approach of Scotrenewables aimed at keeping maintenance costs to a minimum.
Mark Hamilton, managing director of Scotrenewables, said: "The SR2000 turbine is of major importance to the company and represents the full-scale version of our technology.
"Gray Fabrication were selected as our preferred fabricator for this key contract after an extensive tendering process with fabricators across the UK.
"We are delighted to award the contract to a fabricator within Scotland, and Gray Fabrication are a shining example of the strength and quality of the Scottish manufacturing sector. We look forward to working with them as our project and the wider marine renewables industry continues to develop."
