T/SSLIA 001-2025 Guidelines for Safety Inspection of Natural Gas Liquefaction Plants
T/SSLIA 001-2025 Natural gas liquefaction plant safety inspection guidelines
Basic Information
Scope
Scope: These guidelines apply to factories that produce liquefied natural gas (LNG) primarily from methane, covering the entire process of safety inspections including raw material pretreatment, liquefaction, storage, transportation, and supporting facilities. Main technical content: Chapter 4: Basic Requirements: Introduces a three-in-one inspection mechanism of "full participation + risk grading + digital tools", and specifies the frequency of daily inspections, quarterly inspections, and special inspections. Chapter 5: Risk Grading: Establishes a three-dimensional quantitative evaluation matrix of accident consequences (5 levels) × occurrence probability (5 levels) × effectiveness of control measures (3 levels). Chapter 6: Inspection Implementation: Refines the full process of "plan formulation - on-site inspection - rectification tracking", and provides a hazard rectification notice form (Appendix C). Appendices A/B: Innovatively design safety document management checklists (containing 132 indicators in 18 categories) and on-site inspection checklists (covering 7 major process units and 236 key control points).
