ABB has revealed that the Stublach gas storage facility, which is being built for Storengy, will be controlled by ABB System 800xA along with instrumentation from the company.

The ABB System 800xA control system along with ABB instrumentation provides inherent asset-monitoring facilities to assist operators manage and maintain the plant to increase productivity and reduce energy usage.

The Stublach facility is being built in Cheshire and will store gas in salt caverns deep underground.

The plant consists of gas compressors, which move the gas between the caverns and the National Grid Transmission System (NTS).

In addition, an on-site drying plant removes water from the gas before it is returned to the NTS.

ABB will act as the main instrumentation and automation contractor.

It 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, which is responsible for engineering, procurement and construction of the plant.

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

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

This will be engineered by TUV-certified ABB engineers based in St Neots, Cambridgeshire.

As availability and efficiency of the plant are crucial, the System 800xA controllers will be in a redundant configuration.

The 800xA system also interfaces to fire and gas monitors around the plant, as well as third-party packages such as the compressor unit controls to monitor and control the plant.

This provides integrated visibility for the operators of the process, plant assets, along with the safety aspects for both plant and personnel.
