The Rough field is situated in the Southern North Sea, 18 miles off the coast of East Yorkshire. We have two offshore installation hubs called 3B and 8A where gas is injected and extracted through up to 30 wells, which have been drilled through the platforms down into the reservoir thousands of feet below the seabed.
Gas is extracted as a vapour offshore, before being sent via a 91cm (36inch) diameter subsea pipeline to the Easington gas terminal where the gas undergoes several separation processes. Before being sent into the National Transmission System (NTS), which is used to transport the gas throughout the UK before it reaches people homes.
At the Easington gas terminal, Centrica Storage also processes and ships gas from Centrica Energy’s York gas field, located just a few miles from Rough. In 2011/12, the Essington terminal underwent a multi-million pound upgrade to prepare it for receiving gas from the York field. York gas flowed into the terminal in March 2013, where it was processed and shipped into NTS. The success of this operation has paved the way for further collaboration between Centrica Storage and other potential Southern North Sea gas operators looking to send their gas onshore.
Around 350 staff and contractors are employed within the operation, both onshore and offshore.
