Field operators and developing operations personnel
LNG Plant Operator
A system-first pathway for understanding LNG process flow, equipment, storage, BOG, sendout and the safeguards that shape normal and abnormal operation.
Role learning outcomes
A practical curriculum target for the role.
- Trace the major LNG process path and connected utilities.
- Relate field equipment to PFDs, P&IDs and operating logic.
- Recognize key operating variables, alarms, trips and protective responses.
- Understand how storage, BOG and sendout systems interact.
Possible evidence in a workplace program
- • System walkdowns or equivalent familiarization records
- • Procedure-based task observations
- • Knowledge assessments
- • Approved operating qualification evidence where the employer uses it
Employer authorization, site qualification and licensing remain separate from LNG University learning records.
Foundation
Build the technical language and system context needed before role-specific depth.
Foundational
LNG Properties, Cryogenics and Phase Behavior
Build the physical foundation needed to understand why LNG equipment, materials, operating limits and safeguards are different from conventional ambient-temperature hydrocarbon systems.
Foundational
Process Flow Diagrams (PFDs) for LNG Facilities
Learn to read an LNG process at system level by following major equipment, streams, operating conditions and material or energy flows on a PFD.
Intermediate
Piping & Instrumentation Diagrams (P&IDs)
Develop the ability to read the detailed relationship among process piping, valves, instruments, equipment, control loops and safeguards on LNG P&IDs.
Core role knowledge
The principal systems and technical subjects most directly connected to the role.
Intermediate
LNG Storage Tanks and Tank Systems
Understand the major systems around LNG storage tanks, including containment, insulation, instrumentation, pressure management, pump columns and safeguards.
Intermediate
LNG Tank Instrumentation and Inventory Measurement
Understand the level, temperature, pressure and density-related measurements used to monitor LNG tank inventory and thermal condition.
Intermediate
Cryogenic In-Tank Pumps
Study submerged LNG pumps, pump columns, motor arrangement, hydraulic behavior and the operating considerations that arise from cryogenic service.
Intermediate
Boil-Off Gas Management
Understand the sources, collection, compression, recovery and disposition of BOG across storage, unloading, loading and regasification operations.
Foundational
LNG Regasification Process
Follow LNG from storage through pumping, BOG recovery, vaporization, metering and pipeline sendout.
Intermediate
Control Valves and Final Control Elements
Study how control valves convert controller output into process action and how sizing, trim, actuator behavior, positioners and process conditions affect controllability.
Advanced & protection context
Deeper control, safeguard or specialist knowledge that strengthens decision-making and cross-functional understanding.
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.
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.
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.
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.
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.
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.
