Public curriculum specification
LNG Process Safety, Commissioning & Startup
Commissioning personnel, process-safety professionals, operators, project engineers and technical leaders
Connect hazard analysis, inerting, commissioning, cooldown, startup, shutdown and emergency protection into one lifecycle-oriented technical program.
Review cadence: At least annually and whenever material curriculum, assessment or scope requirements change. How curriculum governance works →
Learning outcomes
What the program is structured to develop.
- Explain key commissioning steps before hydrocarbon introduction.
- Understand why inerting, gas testing and controlled cooldown are sequenced.
- Relate HAZOP/LOPA concepts to safeguards and startup readiness.
- Differentiate normal shutdown, ESD isolation and depressurization.

LNG Spills, Vapor Dispersion and Thermal Hazards
Understand the physical behavior of released LNG, vapor cloud formation, dispersion influences and the principles behind spill containment and emergency planning.
Open topicProcess Systems · Intermediate
Nitrogen and Inert Gas Systems
Understand the use of nitrogen for purging, inerting, padding and maintenance support across LNG facilities.
Open topicProcess Systems · Advanced
LNG Commissioning, Purging and Cooldown
Study the staged preparation of LNG systems for hydrocarbon introduction, including cleanliness, leak testing, inerting, purging and controlled cooldown.
Open topicProcess Systems · Advanced
LNG Facility Startup and Shutdown Philosophy
Understand the system dependencies, sequencing and stabilization concepts that shape startup, normal shutdown and emergency shutdown of LNG facilities.
Open topicControls & Protection · Intermediate
DCS, SIS and Emergency Shutdown Systems
Understand the different roles of the distributed control system, safety instrumented system and emergency shutdown functions in an LNG facility.
Open topicValves & Protection · Intermediate
Emergency Shutdown Valves (ESDVs)
Learn how ESDVs isolate inventories or process sections during defined shutdown scenarios and how valve fail position, actuator design and shutdown logic fit into the protective architecture.
Open topicValves & Protection · Intermediate
Blowdown Valves (BDVs) and Depressurization
Understand how BDVs support controlled depressurization of process inventories during shutdown or emergency scenarios and why blowdown capacity, destination and timing are engineering decisions.
Open topicValves & Protection · Intermediate
Pressure Safety Valves (PSVs)
Understand the purpose, terminology and process-safety role of pressure safety valves protecting LNG equipment and piping against credible overpressure scenarios.
Open topicSafety Systems · Intermediate
Flare, Vent and Safe Disposal Systems
Study how relief, depressurization and vent streams are collected and routed to controlled disposal systems during normal, upset and emergency conditions.
Open topicSafety Systems · Intermediate
Fire & Gas Detection Systems in LNG Facilities
Study the detection and response architecture used to identify flammable gas, fire or cryogenic release hazards and initiate alarms or protective actions.
Open topicValves & Protection · Intermediate
Cryogenic Valves, Materials and Low-Temperature Design
Understand how cryogenic temperature affects valve construction, materials, stem arrangements, sealing, thermal contraction and isolation strategy in LNG service.
Open topicAssessment framework
Assessment is defined by the active program.
- Technical knowledge assessment
- Commissioning-sequence exercise
- Hazard/safeguard case analysis
- Project or workplace evidence only where explicitly specified
Possible evidence
Evidence examples for governed delivery.
- Commissioning-system review
- Hazard-analysis exercise
- Startup/shutdown scenario assessment
- Approved project evidence where applicable
