Systems integration specialist Hima-Sella commences work on three safety solutions for Total E&P UK at its St. Fergus gas terminalStockport, United Kingdom - Systems integration specialist Hima-Sella has been awarded and has commenced work on three contracts to provide solutions to protect against overpressure scenarios at the Total E&P UK Ltd gas terminal at St. Fergus, Scotland.
Under a contract awarded by Wood Group PSN, Hima-Sella is upgrading an existing Over Pressure Protection System (OPPS). The company is also contracted by valve manufacturer Mokveld to provide and install a new High Integrity Pressure Protection System (HIPPS) and a new Interlock Over Pressure Protection System (IOPPS)
Each system is being implemented using a HIMA Planar 4 solid state logic solver connected to pressure transmitters fitted to the interlocking manifolds of the pipelines they protect. In the event of an overpressure scenario, the Planar 4 (which is SIL 4 capable) will send shutdown signals to the respective safety valves.
Hima-Sella is also providing a HIMA HIMatrix system (itself SIL 3 rated) as a controller for 'Sequence of Events' reporting and pressure transmitter discrepancy calculations.
Eddy Turnock, Hima-Sella's Sales & Marketing Director, comments: "These three projects reaffirm Hima-Sella's position as a supplier of safety instrumented systems and professional engineering services into the oil and gas industry. In addition, the systems in question, and the way we architect safety around safety critical infrastructure such as valves, provide the highest level of protection whilst affording operational efficiency."
All essential system components have been delivered and are scheduled for installation during the summer. Commissioning is scheduled for mid- to late-September.
