SABIC safeguards UK pipeline
17 Nov 2011
London – Hima-Sella has completed delivery on safety systems for all 20 valve stations along the length of SABIC UK Petrochemicals’ 250km-long Wilton-Grangemouth ethylene pipeline (WGEP), one of a number of pipelines used to link ethylene production plants in the UK.
The installations are part of an upgrade programme that commenced in 2010 and includes the replacement of the valve stations’ remote terminal units (RTUs) and hardwired valve interlocks with a BS EN 61508 safety system.
At the valve stations, which are in remote locations, a number of parameters are monitored including valve positions, upstream and downstream pressures, temperatures, cathodic protection, battery charger status and product flows.
Localised safety within each valve station is delivered via a HIMA HIMatrix F35 programmable electronic system (PES), which has eight analogue inputs, 24 digital inputs, eight digital outputs, three Fieldbus ports and four configurable Ethernet ports.
All 20 PESs for the WGEP upgrade were programmed by Hima-Sella using HIMA’s IEC 61131- 3-compliant ELOP II software tool. In a separate contract, Hima-Sella has provided another SIS based on a HIMatrix PES to protect SABIC UK Petrochemicals’ Teesside, Arthur Taylor Jetty Arm.
