Specialist safety instrumentation systems provider Hima-Sella has received an order for the design, manufacture and installation of an upgrade to a large Norwegian oil and gas refinery’s P1 Alarm system.
At the heart of the upgrade will be a HIMA HiQuad H51q Programmable Electronic System. It will interface with the refinery’s digital control system and feed all alarm data to a new SCADA HMI; which is based on a dual redundant server in separate locations. Each server will have two screens which can view data from either server. The screens will emulate the existing lamp-driven displays.
The purpose of a category P1 Alarm system is to protect plant personnel and buildings plus call out first responders. The upgrade is being designed to meet not only the end-user’s alarm functionality requirements but also the refinery’s cyber-security needs (and is to be compliant with IEC 62443-3-3).
