ABB won a main automation and instrumentation contract for a new natural gas storage facility in Cheshire, UK.

The facility will hold over 400 million cubic meters of gas, and ABB System 800xA along with ABB Instrumentation will control the plant. The Stublach facility is for Storengy (a GDF Suez company) in Cheshire and will store gas in salt caverns deep underground.

The processing plant consists of gas compressors which move the gas between the caverns and the United Kingdom’s National Grid Transmission System (NTS). Additionally, an on-site drying plant removes water from the gas before it returns to the NTS. The site should operate for over 25 years.

ABB will provide engineering design services for the automation, safety instrumented system (SIS) along with the supply of an 800xA Integrated Process Control system and 800xA based SIS, ABB and third party instrumentation to Jacobs Engineering who are responsible for Engineering, Procurement and Construction of the plant.

Cyber Security

The ABB system will control the import of gas into the caverns for storage and export of gas into the grid; this includes the complex control required to handle these transfers in free flow and compression modes.

Plant safety is critical and the TUV certified AC 800M HI controllers along with the field devices used as the SIS will control the processing plant, associated pipelines and the well heads, which are up to 2 km from the processing plant.
