The liquefied natural gas (LNG) supply chain utilizes significant amounts of resources due to its stringent processing requirements. Reducing such resources is economically and environmentally desirable. However, no rigorous, fully validated simulation model exists for the entire chain to serve as a powerful and cost-effective tool for optimization and other reliable analyses. In this work, we used actual data to construct a full chain rigorous simulation model spanning all units from the wellhead to transportation and regasification. In addition to key simulation results, we presented an effective systematic approach for the simulation while discussing essential operating envelopes and constraints that must be respected to obtain reliable predictions. Using the model, we performed an energy and environmental analysis to thoroughly quantify chain losses, emissions and wastes. This model will serve as the basis for a series of publications on the optimization and analysis of the LNG chain.

液化天然气（LNG）供应链由于其严格的处理要求而占用了大量资源。减少这种资源在经济和环境上是合乎需要的。但是，对于整个链，没有严格的，经过充分验证的仿真模型可以用作优化和其他可靠分析的强大且经济高效的工具。在这项工作中，我们使用实际数据构建了一个完整的，严格的模拟模型，涵盖了从井口到运输和再气化的所有单元。除了关键的仿真结果，我们还提供了一种有效的系统方法进行仿真，同时讨论了获得可靠预测所必须考虑的基本操作范围和约束条件。使用模型，我们进行了能源和环境分析，以彻底量化链损失，排放和废物。该模型将作为有关LNG链的优化和分析的一系列出版物的基础。
