摘要

Safety is of paramount importance in the design of any process plant and in particular of LNG liquefaction as well as regasification plants. In principle, an LNG plant should be in compliance with the safety requirements, norms, policies and guidelines issued by local and international authorities. How to comply with these standards, in a logical and systematic way during engineering design, to ensure the integrity of an LNG plant under all foreseeable ways of operation is discussed in this paper. Similarly, it emphasizes the need to discuss hazardous situations and incidents that could happen and that have to be resolved quickly to minimize uncontrolled loss of containment and how operational risks have to be assessed for acceptability in order to deliver a cost effective design. The use of standards such as the National Fire Protection Association (NFPA- 59A), its provisions and alternatives are discussed in determining the hazard footprint of a facility. This includes the evaluation of risks to facilities inside and outside the plant (thermal radiation and vapor dispersion calculations) due to possible spill scenarios and in the possible event of a terrorist attack on storage tanks, ships, etc. with the corresponding release of LNG. The paper illustrates the application, to LNG plants, of the International Electrotechnical Commission (IEC-61508/61511) procedures to determine that the safety level of the instrumentation system is consistent with the risk acceptance criteria of the project. The importance of using HAZID and HAZOP procedures at different points in the design, as well as several 3D model reviews of the plant by an audit team are described.
