Oil & Gas Engineering Expertise
Every deliverable is simulation-validated and code-compliant — from HYSYS heat and mass balance tables to Caesar II stress isometrics and HTRI thermal design reports. No rule-of-thumb sizing, no assumption-driven design.
What We Deliver
Steady-state and dynamic process simulation for oil and gas, refinery, and petrochemical facilities using Aspen HYSYS for upstream and midstream operations, and Aspen Plus for refinery and chemical processes.

HAZOP & HAZID Support
Process safety starts at design stage — not after construction. KVRM provides engineering support for HAZOP and HAZID studies, ensuring P&IDs are prepared to a standard that enables effective hazard identification.
KVRM provides engineering support before, during, and after HAZOP and HAZID studies — ensuring P&IDs are accurate and complete, design assumptions are documented, and HAZOP action items are closed with appropriate engineering responses. Our Aspen HYSYS simulation models provide the quantitative basis for consequence assessment and PSV sizing (API 520/521).
- P&ID review and mark-up for HAZOP preparation
- HAZOP Node definition and design intent documentation
- Cause and consequence analysis support
- HAZOP action item tracking and engineering response closure
- HAZID facilitation support for early-stage projects
- Safeguarding review — SIS, BPCS, and pressure relief
- PSV sizing using Aspen HYSYS (API 520 / API 521)
- Layer of protection analysis (LOPA) support
