ALL 27 turbines on a Tees Valley offshore windfarm have now been installed.
The massive ship MPI Adventure is pictured taking the last two turbines out from Hartlepool to the EDF Energy Renewables Teesside offshore windfarm.
But bosses say Hartlepool will continue to be the base for workers on the project as electrical and other works are carried out.
The MPI Adventure is a large six-leg jack up vessel designed to transport, lift and install turbines. It has taken turbines out of Hartlepool for months, out to the project off the coast of Redcar.
Once completed, the wind farm will be capable of generating electricity equivalent to the consumption of 40,000 households.
After installation a commissioning and testing programme is undertaken by the wind turbine generator manufacturer, Siemens, to ensure that each is ready for operation.
Once completed, the windfarm will be capable of generating up to its full output of 62 megawatts.
A spokesman said: “All 27 turbines were installed using MPI. Eight of them are fully electronically commissioned and supplying power to the grid.
“Work on bringing the other turbines into supplying power is continuing and that is the focus of attention now.”
Cables buried on the seabed transmit the electricity from the wind turbines to a newly constructed substation at Warrenby where the voltage is boosted to reduce transmission losses before entering the electrical grid via a connection at Lackenby.
