Abstract: In response to the multi-subject cooperative design, tight schedule and high difficulty in the design of the Lekki deepwater port project in Nigeria, the BIM technology research on port engineering collaborative design has been carried out.Autodesk Vault platform is used to integrate various software and file formats for collaborative design.The conclusion is drawn that BIM technology in port engineering can achieve cooperative design, pipeline integration, deepening design, and etc., which can effectively improve the quality and efficiency of port engineering design, reduce the problems such as "mistake and miss" in the design process, and reduce the project cost.As a conclusion, BIM application should the main direction and trend of design engineering.
