They keep trying, but tidal turbines have yet to make it to the big league in terms of competing with established alternatives like wind turbines. The report calls it a vessel.

Scottish floating tidal turbine technology provider Orbital Marine Power has successfully launched its 2MW tidal turbine, the Orbital O2, from the Port of Dundee , reports insider.co.uk.
The operation was managed by Osprey Heavy Lift and saw the 680-tonne tidal turbine transferred from the Forth Ports quayside facility in Dundee into the River Tay using a submersible barge.
The launch marks the completion of the turbine build, managed by TEXO Fabrication, and the O2 will now be towed to the Orkney Islands, where it will undergo commissioning before being connected to the European Marine Energy Centre (EMEC), becoming the world’s most powerful operational tidal turbine.
Orbital’s chief executive Andrew Scott, said: “This is a huge milestone for Orbital; the O2 is a remarkable example of British cleantech innovation and the build we have completed here is an inspiring display of what a UK supply chain can achieve if given the opportunity – even under the extraordinary pressures of a pandemic.”

The launch of the O2 also marks the first vessel launch from Dundee since ship building ended over forty years ago.
The turbine has the ability to generate enough clean, predictable electricity to meet the demand of around 2,000 UK homes and offset approximately 2,200 tonnes of CO2 production per year.

The O2 turbine has a 74m long hull structure with twin 1MW power generating nacelles at the end of retractable leg structures designed to give low-cost access to all major components for through life servicing.
Its 10m blades give more than 600m of swept area to capture flowing tidal energy. The floating structure is held on station with a four-point mooring system where each mooring chain has the capacity to lift over 50 double decker buses.
The O2 has been designed so that installation of the turbine, and all its associated moorings, can be carried out by low-cost work vessels and servicing can be carried out by RIB vessels – minimising downtime and lowering construction and operational costs.
Electricity is transferred from the turbine via a dynamic cable to the seabed and a static cable along the seabed to the local onshore electricity network.
