Executing projects in Control & Automation Systems for over 30 years covering the full life cycle from Concept to Design, Engineering, Contruction, Commissioning, Start-up and Process Optimisation has resulted in diverse experience and us delivering real value to our customers. We look forward to working with you to delivering your requirements.
Critical decisions are made after the PHA/LOPA and before detailed design that have significant impact in the full lifecycle of a Safety Instrumented System.
The Abalto process for design and implementation of ISA84/IEC 61511 compliant industrial safety instrumented systems is based on knowledge and experience in PHA/LOPA along with control system hardware, software and field instrumentation to ensure that Safety Instrumented Functions (SIFs) are clearly defined and realised.
The true value of the Abalto integrated approach to SIS engineering is to:
- Ensures IPL verification and selection is well defined to minimise rework
- Demonstrate that designs comply with ISA84/IEC 61511 from the beginning
- Optimise capital costs against proof test frequencies
- Ensure the optimisation of process safety and runtime reliability
