Engineering of LPG Bullets Maintenance Depressurization Piping

This project involves the detailed engineering design of a new blowdown system for ten LPG storage bullets at the Khor Mor LPG Plant operated by Pearl Petroleum in the Kurdistan Region. The objective is to enable safe, controlled, and independent depressurization of each LPG bullet without interrupting truck loading operations. The proposed system will route blowdown vapors from each bullet to a common header connected to the existing flare system, ensuring compliance with ASME B31.3, API 521, and COMPANY isolation philosophy requirements. The scope includes piping, structural, and stress analysis design, tie-in engineering, 3D modeling, material take-offs, and HAZOP review to enhance operational flexibility, safety, and environmental compliance. Additionally, the project includes assessment and optimization of the existing cold vent system using DNV PHAST dispersion analysis.
