Protection for gas field
Published: 30 August 2012 - Joe Bush
Hima-Sella is providing emergency shutdown and automated overpressure protection systems in relation to a gas field in Teeside.
The company has commenced work on two contracts for the design, manufacture and installation of safety systems for the Teeside Gas Processing Plant at Seal Sands in Middlesborough, which is currently being modified to receive and process gas from the Breagh field in the North Sea.
Under the first contract, awarded by AMEC, the company is providing an emergency shutdown system (ESD) at the processing plant. The ESD is being built around a HIMA HIQuad H51q-HS (SIL 3 rated) programmable electronic system (PES), which features dual redundant CPUs and will reside in four system cabinets (three of which will be at the processing plant and a fourth that will be located on the unmanned Breagh Alpha platform - approximately 100km offshore).
Under the second contract, awarded by J. Murphy & Sons, a civil engineering and building contractor, the company is providing a high integrity pressure protection system (HIPPS), which will be located at a beach valve compound (a landfall site about 10km from the processing plant for a 20” class 1500 pipeline from the Breagh Alpha platform). The HIPPS will also be based on the HIMA HIQuad H51q (PES) and will perform 2oo3 voting on pressure transmitters to provide autonomous and fail-safe protection of the downstream pipeline against overpressure.
Andy Tonge, Hima-Sella’s Sales Manager, commented: “The Breagh field is one of the largest gas discoveries in recent years and it is helping secure the UK’s future energy needs. We’re therefore delighted to have been awarded these two contracts to engineer solutions to protect the Breagh Alpha platform and the 110km of pipeline to the Teeside Gas Processing Plant.”
The ESD and HIPPS are scheduled for delivery in Q3 of this year.
