In 2011, Servelec Controls was asked to design, implement and commission an emergency shutdown (ESD) safety system as part of Centrica Storage’s York field development project undertaken on the operational brownfield Easington gas terminal. The Easington gas terminal is one of three main terminals that process gas from the UK Continental Shelf. Easington accepts and processes gas from ten fields off the East Yorkshire coast as well as from the Langeled pipeline, the world’s longest subsea pipeline which imports gas from Norwegian producers into the UK’s National Transmission System.

The York field development project consisted of three main aspects:

  • New offshore normally unmanned installation (NUI) located in the York field off the north-east coast of the UK, providing enough gas to meet the demands of half a million households.
  • New offshore pipeline from the NUI to the existing Easington Terminal.
  • New facilities and modifications to the Centrica Storage Easington Terminal.

The project included new facilities and modifications to the existing, redundant Amethyst processing train, which forms part of the Easington Terminal. The terminal’s processing facility consists of inlet separation, dewpointing, heating, metering, utility and auxiliary systems.

The processed gas from the York field is exported to the National Grid while condensate and water that are removed from the gas are processed, stored and exported via the existing routes.  The emergency shutdown system provided by Servelec Controls ensures that in the unlikely event of an emergency situation, people, environment and plant are protected by a vital layer of protection if hazardous conditions occur.

Servelec Controls provided design, implementation and commissioning services for the emergency shutdown system ensuring the work was delivered on time and on budget.

The solution provided by Servelec Controls included:

  • SIL 2-rated GE PAC8000 SafetyNet Controller logic solver and IO equipment, power supplies, barriers and marshalling housed in front and rear double bay cabinets.
  • SIL 3- rated ABB 800xA Logic solver and I/O equipment, Modbus communications equipment, power supplies, power distribution, barriers and marshalling.
  • A 1U Power Edge Dell server engineering workstation and a 1U Power Edge Dell server, keyboard monitor and video (KVM) CAT 5 extender, Catalyst CISCO switches and distribution equipment.
  • Application software including ABB 800xA, GE PAC8000 SafetyNet logic solver functional logic and any other system configuration necessary to meet the requirements of specification.

Servelec Controls’ flexible approach and familiarity with the site and plant architecture and systems helped Servelec Controls deliver the project on-time and on-budget. Our team was dedicated to the project throughout the development and installation of the system, ensuring consistent delivery of knowledge and a familiar point of contact for the project team. 

Servelec Controls provides ongoing project work and support for Centrica’s onshore and offshore assets and is an industry leader in the design and implementation of automated control and functional safety systems for mission-critical applications.
