Process Safety & Engineering Services for the LNG Industry
The Liquefied Natural Gas (LNG) sector presents unique operational and regulatory challenges across liquefaction, storage, transport, and regasification. At Smith & Burgess, we deliver comprehensive process safety and engineering consulting to ensure safe, efficient, and compliant LNG operations.
Our engineers bring decades of experience—from greenfield export terminals to midstream storage and regasification facilities—addressing boil-off gas management, complex flare networks, facility expansions, and more. We partner with you to develop practical, standards-based solutions that align with global regulations and your specific operating needs.
Compliance expertise includes:
- PHMSA 49 CFR Part 193
- OSHA 29 CFR 1910.119
- EPA 40 CFR Parts 60.18 & 68
- NFPA 59A
- IFC 603, 5003, and 6004
- API 520 & 521

Pressure Relief and Flare System Studies
for LNG Facilities
Overpressure scenarios in LNG environments demand specialized modeling and mitigation. Our Relief & Flare System Studies ensure your relief devices and flare networks perform reliably and comply with API 520/521 and global best practices.
Key services:
- Overpressure scenario identification & dynamic hydraulic modeling
- Flare header hydraulics, knock-out drum sizing, and backpressure analysis
- Relief valve & rupture disk sizing (API 520/521)
- Flare system debottlenecking & optimization
- Documentation for PSI compliance and audit readiness
We leverage deep technical know-how, proven methodologies, and our SalusTM software platform to solve your most pressing challenges.
