Programme overview
Introduction:
Staff moving into liquefied natural gas (LNG) projects often understand only their own link of the chain, so feed gas specifications, boil-off losses, cargo scheduling and regasification send-out are planned in isolation and the cryogenic hazards are underestimated. This Core Concept course follows LNG from feed gas pre-treatment and liquefaction through full containment storage, carrier loading and shipping to regasification terminals and FSRUs, then covers LNG safety, contract and pricing basics and small-scale LNG. Participants walk through each facility type and produce an LNG Value Chain Map and Hazard Register for their own role.
Course Objectives:
- Explain LNG composition, cryogenic properties, volume reduction and heating value and relate them to feed gas specifications
- Describe the pre-treatment units that remove acid gas, water, mercury and heavy hydrocarbons ahead of the cold section
- Compare the published liquefaction processes and trace refrigerant cycles and main cryogenic heat exchanger duty on a process flow diagram
- Track boil-off gas generation in storage tanks, jetty lines and carrier cargo tanks and select handling routes such as compression, fuel use and reliquefaction
- Identify rapid phase transition, cryogenic embrittlement and vapour cloud hazards and match them to the safeguards found on LNG terminals and ships
- Interpret the main terms of LNG sale and purchase agreements and price indexation and compile an LNG Value Chain Map and Hazard Register
Target Audience:
- Process and mechanical engineers joining liquefaction, storage or regasification projects
- Operations and maintenance staff responsible for LNG tank farms, jetties and vaporiser trains
- Commercial and shipping staff who schedule cargoes, nominate volumes and administer LNG contracts
- Planning and supply chain staff who forecast send-out and coordinate carriers with terminals
- HSE advisers responsible for cryogenic hazard assessment at gas terminals
- Project and asset integrity staff moving from pipeline gas or oil into LNG assets

- LNG Value Chain Map and Hazard Register Drafting and Peer Review
Skills You Will Gain:
- LNG Property Interpretation
- Gas Pre-Treatment Specification
- Liquefaction Process Recognition
- Boil-Off Gas Management
- Cargo Containment Awareness
- Regasification System Selection
- Cryogenic Hazard Identification
- LNG Contract Literacy
Why Attend This Course:
- Leave with an LNG Value Chain Map and Hazard Register built from walkthroughs of liquefaction, storage, jetty and FSRU layouts
- Talk with process, shipping and commercial colleagues using the same terms for boil-off, send-out, cargo energy and delivery point
- Spot rapid phase transition, cold spill and vapour cloud scenarios before they appear in a design review or a site visit
- Compare LNG practice with engineers, operators and traders from producing, shipping and importing organisations
Conclusion:
Working safely and profitably in LNG depends on seeing how each link of the chain affects the next: feed gas quality sets liquefaction duty, tank heat leak sets boil-off, cargo containment sets shipping losses and vaporiser choice sets send-out. The course moves from LNG properties and the value chain, through pre-treatment and liquefaction technology, storage, boil-off and loading, to regasification, FSRUs and hazard safeguards. The final day adds contract, pricing and small-scale basics and produces an LNG Value Chain Map and Hazard Register for each participant.
