Central Area Transmission System

The Central Area Transmission System is a gas terminal and transportation facility at Seal Sands near Middlesbrough with multiple processing and pumping stations. The site consists of a large network of pipelines, storage tanks, and treatment units that handle gas coming from the North Sea.

Construction of this infrastructure began in 1993 and was then the second largest construction project in the United Kingdom after the Channel Tunnel. The facility expanded gradually to meet growing demand for gas processing and distribution.

The facility has become a symbol of regional energy infrastructure and has shaped the Teesside coastline for decades. Visitors can observe the massive installation from outside and understand how central it is to local industry and national energy supply.

The site is located in an industrial area best reached by car or public transport, with limited visitor access available from outside. The best time to visit is during daylight hours when the facility's operations are visible.

The facility connects to numerous offshore gas fields through a central riser platform located in the central North Sea. This underwater connectivity allows it to process gas from multiple sources simultaneously, a technical feature that visitors cannot directly see from land.
