Public curriculum specification
LNG Mechanical Maintenance & Reliability
Mechanical technicians, rotating-equipment personnel, reliability engineers and maintenance professionals
Build equipment-centered knowledge across compressors, pumps, valves, cryogenic service and condition-focused maintenance context.
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.
- Identify the operating purpose and major components of LNG rotating and mechanical equipment.
- Recognize equipment protection and operating-envelope concepts.
- Connect equipment condition to process consequences.
- Use P&IDs, OEM information and equipment data as maintenance references.
Technical curriculum
13 connected technical subjects
LNG Fundamentals · 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.
Open topicEngineering Drawings · 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.
Open topicRotating Equipment · Intermediate
Centrifugal Compressors in LNG Service
Understand the operating principles, performance limits, major components, auxiliaries and protection philosophy of centrifugal compressors used in LNG and gas-processing facilities.
Open topicRotating Equipment · Advanced
Dry Gas Seals for Centrifugal Compressors
Study the purpose, arrangement and monitoring of dry gas seals used to limit process-gas leakage from centrifugal compressors.
Open topicRotating Equipment · Advanced
Compressor Performance Monitoring
Understand how operators and engineers use pressure, temperature, flow, vibration and map position to evaluate centrifugal-compressor performance and degradation.
Open topicRotating Equipment · Intermediate
Boil-Off Gas (BOG) Compressors
Study the role of BOG compressors in controlling LNG tank and transfer-system vapor generation while maintaining a stable vapor-handling path.
Open topicRotating Equipment · Intermediate
Cryogenic In-Tank Pumps
Study submerged LNG pumps, pump columns, motor arrangement, hydraulic behavior and the operating considerations that arise from cryogenic service.
Open topicRotating Equipment · Intermediate
LNG High-Pressure Sendout Pumps
Understand how high-pressure LNG pumps raise liquid pressure before vaporization and how their hydraulic operating envelope connects storage, recondenser and vaporizer systems.
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 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 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 topicMarine & Transfer · Intermediate
LNG Marine Loading Arms and Transfer Systems
Understand the mechanical, hydraulic and shutdown functions of LNG loading arms used for liquid and vapor transfer between terminal and vessel.
Open topicAssessment framework
Assessment is defined by the active program.
- Equipment knowledge assessment
- Component/system identification exercises
- Failure-symptom or troubleshooting scenarios
- Workplace task evidence only in employer-scoped programs
Possible evidence
Evidence examples for governed delivery.
- Maintenance observation
- Inspection or condition record
- OEM-based task evidence
- Knowledge assessment
Choose the delivery relationship
The same program can enter through different governed relationships.
Individual access, corporate deployment, institutional use and verified partner learning have different commercial, assessment and evidence requirements.
