BIM技术在大型LNG储罐建设中的应用前景

大型LNG储罐的建设具有涉及专业繁多并交叉作业、工艺技术要求高、建设周期长和运营维护复杂等特点。因此,科学的管理方法和先进的工程建设理念对提高储罐建设的质量和效率、节约成本等方面具有重要的作用和意义。BIM(Building Infotmation Modeling)技术采用4D建模方法对建设工程的全部相关信息进行系统化管理,并通过统一控制和无缝交流的共享方式实现工程建设目标。结合大型LNG储罐建设的自身特点,引入BIM技术,通过建立虚拟模型和模拟工况,可对整个工程建设和运营过程进行优化控制,最终达到提高质量和节约成本等目的。鉴于中国目前已掌握了大型LNG储罐建设的传统管理方法和建造技术,引入BIM技术的条件基本具备。在未来LNG产业的发展中,该技术将在大型LNG储罐的全过程管理中发挥重要的作用。同时还建议,受技术垄断的限制,我国应加强"标准统一、技术同步、知识产权"等方面的攻关研究。

Application prospect of BIM in the construction of large-scale LNG storage tanks

Large-scale LNG storage tank construction is so complicated that it involves multi-disciplines, cross-operation, high technical requirements, long construction periods, and quite sophisticated follow-up operation and maintenance. Scientific management and advanced engineering construction concept will be of great significance to improve the quality and efficiency of LNG storage tank construction, save the cost, and so on. The BIM (Building Information Modeling） technology adopts the 4D-modeling methodology to systematically manage all the involved information in a construction engineering project and to achieve the construction goal by uniform control and seamless communication with the information sharing. In combination with the characteristics of a large-scale LNG storage tank construction project, the BIM was introduced to build a virtual model simulating the actual working conditions, which will optimize and control the whole construction and operation process, thereby to improve the quality and reduce the cost. Under the present situation, China is equipped with introducing the BIM technology into the large-scale LNG storage tank construction projects. In the future LNG sector, the BIM will play an important role in the management of large-scale LNG storage tank construction and operation projects. Meanwhile, it was also pointed out that in order to overcome technological monopoly restrictions, China should try to make great breakthroughs in the aspects of standard criteria, synchronous technologies, and protected intellectual properties, and so on.
