Hima-Sella has completed delivery on safety solutions at all 20 valve stations along the length of SABIC UK Petrochemicals’ 250km Wilton-Grangemouth Ethylene Pipeline (WGEP), one of a number used to link ethylene production plants in the UK.

The installations include 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. Hima-Sella’s solution for localised safety within each valve station is the 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.
