近年来,随着全球对清洁能源需求的日益增长,液化天然气(LNG)项目的规模也在向大型化发展。与侧重上游投资为主的传统油田项目相比,LNG项目的投资重心转向了下游复杂的液化工程的建设,同时也使之成为LNG项目投产的关键。为进一步了解计划进度管理工作在大型LNG项目中促建设、保投产方面的作用,对俄罗斯亚马尔LNG项目的建造过程进行了跟踪研究。该项目通过计划进度管理技术将复杂的建设过程化整为零,再施以目标设定-按步执行-实时对比-采取纠偏(PDCA)周期性闭环管理,同时借助进度信息平台和计划软件等进度管理工具,最终实现对项目建设的整体规划和控制,有效保障项目按期投产。因此,研究和分析计划进度管理技术在大型油气项目建设的应用,对合理安排建设进程和保障按期投产有积极意义。

Recently, the trend of upsizing is more obvious on LNG project. Comparing with traditional oil field project which mostly focus on up-stream, LNG project pours major investment on complex LNG plant construction down-stream which is the key facility for gas liquefaction and the start-up of entire project. In order to well understand the role of scheduling work within the large LNG project construction, Yamal LNG project is set as a good example to do the study. In this project, with the help of schedule management technology, the whole complex project was broken-down into several small pieces and became a simple one. The PDCA ( plan-do-check-action ) regular closed-loop management and progress information platform & software also play an important role in monitoring and controlling construction progress and final start-up. Basically, schedule management technology is very vital to construction duration control in larger oil and gas project.
