TEXO Engineering and Fabrication was awarded the project to construct the commercial O2 tidal turbine. Once operational, the O2 will be the most powerful turbine in the world. The O2 will is a 72m long floating superstructure, supporting two 1 MW turbines at either side for a nameplate power output of 2MW, at a tidal current speed of 2.5 m/s. With rotor diameters of 20m, it has a 600sq metre rotor area, the largest ever on a single tidal generating platform to date.
We fabricated the turbine at our Port of Dundee quayside facility, which was enlarged during the project. After initial fabrication indoors, the turbine was moved onto the quayside for the addition of legs, forward and aft hull sections and sails. The turbine will then be subject to land testing before being towed to its final position off the coast of the Orkney Islands.
This project is ongoing. The next milestone for the project, which has received funding from the European Union’s Horizon 2020 research and innovation programme under the FloTEC project (grant agreement No. 691916) and the European Regional Development Fund through the Interreg North West Europe Programme under the ITEG project, is for Orbital to conduct land testing on the finished construction, which is anticipated to take place within the next two months.
“This enhanced tidal turbine design has been an outstanding renewables project for TEXO. Whilst there have been both technical and pandemic-related challenges, we have used our expertise and experience to keep the project moving, so that we can deliver the finished turbine early in 2021 when it will be moved by water to Orkney and installed in its operational location.”
