FP McCann’s fire walls installed on Hornsea Substation

FP McCann’s fire walls installed on Hornsea Substation

FP McCann has played a major role in supplying both the precast concrete fire protection walls and the power cable troughs for the Hornsea Project, the largest offshore wind farm in the world, 120 kilometres off the Yorkshire coast.

Once complete in 2020, Hornsea Project One will be capable of generating up to 1.2 gigawatts of power from 174 wind turbines; enough clean, green electricity to power up to 1 million homes across the UK.

To protect the high voltage shunt reactors and transformers on site, five precast concrete fire walls have been constructed all over 11 metres high and formed using FP McCann’s columns and special wall panels, cast offsite. Weighing in excess of 8 tonnes, each of the 32 supporting columns have been located in a pre-formed concrete foundation base. The wall structures comprise of 244 precast concrete infill panels measuring 200mm thick and over 3 metres wide.

FP McCann supplied 675 metres of precast power and communication cable troughs, which run throughout the North Killingholme site below ground level. Standard troughs range in size from 1000mm wide by 1000mm deep, to 600mm wide by 600mm deep. As well as corner and ‘T’ units, a number of bespoke sizes have been manufactured to fit the design brief. These include a number of transition troughs, including a 1250mm by 750mm trough with a 50mm rebate.

The final stages of the construction phase at the substation will be the installation of the fencing and roads. Once completed and with the latest technology and security features, the substation will be almost entirely unmanned.
