Video | Hinkley Point C’s offshore progress

Six giant steel casings, weighing 350 tonnes and 40m long and 6m wide each, have been installed, marking an important step in the construction of the Hinkley Point C’s cooling water system. 

They will form part of the vertical shafts which will connect the five miles of tunnels with the intake and outtake heads. These 5,000-tonne structures were lowered onto the seabed last year and will circulate water to the nuclear reactors. 

The offshore work in the Bristol Channel is approaching completion.
