FUNCTION & CONTROL METHOD
Technology and range are selected from static pressure, turndown, pulsation, plugging, temperature, response and required accuracy. Remote seals, manifolds or purging are applied where process conditions require.
ELECTRICAL, INSTRUMENTATION & AUTOMATION
Pressure Instrumentation
Measures gauge, absolute, differential and vacuum pressure for control, monitoring, equipment protection and custody/process calculations.
MAIN HARDWARE & SYSTEM BOUNDARY
Pressure transmitters, DP transmitters, gauges, switches, manifolds, diaphragm seals, impulse piping/tubing, root valves and junction/remote I/O interfaces.
CRITICAL DESIGN INPUTS
Approved P&IDs and control philosophy, process ranges and alarm/trip limits, hazardous-area classification, environmental conditions, I/O and load lists, availability/redundancy target, package interfaces, communication protocols, cybersecurity and client standards.
ENGINEERING DELIVERABLES
System architecture, instrument/equipment index, datasheets, I/O list, hook-ups, loop and wiring diagrams, cabinet/panel drawings, cable schedule, network drawings, control narratives, cause-and-effect, logic diagrams, graphics, test procedures and as-built backups.
FUNCTIONAL SAFETY, RELIABILITY & CYBERSECURITY
Fail-safe alarm/trip allocation, overrange protection, SIL capability where required, impulse-line segregation and hazardous-area certification are verified.
TESTING, COMMISSIONING & APPLICATIONS
CDU/VDU columns, reactors, drums, filters, pumps, compressors, tanks and utility networks. Calibration, loop check and trip testing are completed before start-up.
CODES, STANDARDS & QUALITY BASIS
IEC 61511 interfaces, ISA practices, ASME process connections, ATEX/IECEx or applicable GOST/EAC hazardous-area requirements.
CONTRACTUAL CODE BASIS
IEC 61511 interfaces, ISA practices, ASME process connections, ATEX/IECEx or applicable GOST/EAC hazardous-area requirements.
