World's Most Powerful Tidal Turbine Launched Offshore Scotland
Tidal power holds a lot of promise for generating clean energy.
As with power from the wind, it can require a lot of engineering
and magnets to harness.
This spring that promise stepped closer to reality when Orbital
Marine Power Ltd, a Scottish-based developer of floating tidal
turbine technology, successfully launched its 2MW tidal turbine,
the Orbital O2. The 680-ton turbine was towed from the
Port of Dundee on April 22 to waters offshore Orkney Island.
Onboard are two permanent-magnet powertrains developed
by SKF, representing a departure from the company's traditional
business of manufacturing bearings, including many
magnetic versions, for industrial equipment around the world.
About 15 meters below the O2's superstructure, the powertrains
are attached on two wing-like legs.
Now comes a period of onsite testing to determine if the innovative
system can deliver according to expectations. On July
28, it commenced generating power to the grid at the European
Marine Energy Centre at Orkney, becoming the world's
most powerful operational tidal turbine.
Strong currents arise where the ebb and flow of tide squeeze
between islands. These are particularly powerful off the
Orkney Islands, which is why experiments with tidal current
power plants have been carried out here for several years at
EMEC which has become Europe's leading test site for tidal
and wave energy projects.
" This is a huge milestone for Orbital, " noted Andrew Scott,
CEO. The O2 turbine started construction in the second half
of 2019. It is designed to generate enough clean, predictable
electricity to meet the demand of around 2,000 UK homes and
offset approximately 2,200 tons of CO2 production per year.
The 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. 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. 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.
