Abstract: The pilot station project in Myanmar is the second offshore pilot station in the world, with its own characteristics novel and complex structure, difficult offshore construction, multi specialties involved, tight design schedule etc. For solving above problems, BIM technology is introduced into the whole process of design and project management to carry out collaborative design, 3D modeling, drawing construction drawings and engineering statistics, collision inspection, pipeline optimization, 4D construction simulation, VR/AR visualization, etc. According to the specific problems, a series of technology development has been carried out, achieving the optimization of technical and economic indicators. The project has investigated and concluded a set of BIM forward design mode and management process, integrating standard specification, collaborative process, targeted scheme and implementation guarantee mechanism, which improves the accuracy and efficiency of deepening the design work, and will provide guidance for the application of BIM technology in the design of offshore building structures.
