• Direct process design across \[4\] concurrent EPC projects — Pars Petrochemical PDH
(UOP-licensed), GTPP Islamabad-e Gharb (Methanol & MTP plants), Tang-e Bijar gas
wellhead, Yadavaran oil wellhead facilities, and the Bandar Abbas Refinery utilities
upgrade — leading a team of \[#\] process engineers.
• Delivered relief load, flare radiation, and PSV sizing studies for the Methanol, PVM, and
PP units of the GTPP mega-project, sizing \[#\] relief devices per API 520/521 and
verifying flare network adequacy in Aspen Flarenet.
• Engineered sizing calculations and datasheets for \[100+\] equipment items (drums,
towers, shell-and-tube exchangers, pumps, compressors, air coolers, silencers, mixers,
filters, reactors), achieving \[first-pass\] approval on \[#\]% of vendor document reviews.
• Standardized piping material specifications for the Bandar Abbas Refinery utilities
upgrade (incl. 000-PA-E-720001 Rev. D5), resolving \[#\] cross-discipline inconsistencies
through systematic P&ID-datasheet-BEDD cross-checking.
• Performed hydraulic studies, natural-circulation assessment of heat-recovery packages,
and natural/forced-draft fired heater sizing, eliminating \[#\] potential operability issues
before IFC.
• Developed, reviewed, and issued \[#\] PFD and P&ID sheets through squad-check and IFC
cycles across wellhead and refinery packages.

• Supervised OSHA-1910.119-based PSM programs as Project Supervisor: full gap
assessment and implementation at Marun Petrochemical and gap assessment at Kavian
Petrochemical, covering all 14 PSM elements across \[#\] units.
• Facilitated HAZID for Bid Boland 2 Gas Refinery and HAZOP for the Arak Oil Refinery
NHT unit; served as core HAZOP team member for Mobin (off-sites), Bouali (naphtha
pre-fractionation), Borzouyeh, Tehran Refinery (NHT & CCR), Damavand (firewater),
and Islamabad (Methanol & PVM) — \[#\] nodes / \[#\] sessions in total.
• Led Job Hazard Analysis teams at Sefiddasht Steel Plant and supervised Risk-Based
Inspection (RBI) implementation at Pars Industrial Carbon, closing \[#\] high-priority
recommendations.
• Directed engineering safety studies for the Tang-e Bijar gas wellhead and Yadavaran oil
wellhead projects, identifying HSE-critical discrepancies (set-pressure conflicts,
hazardous-area classification, NACE MR0175 sour-service gaps) ahead of construction.
