Large-scale overseas heavy chemical investment project of Chinese enterprise usually needs to build individual supporting wharf to complete material transportation,so the site selection of the project largely depends on the wharf’s location.We analyze and summarize the characteristics of wharf site selection for these projects,such as large space span,few clear constraints and deep research depth,and screen several major factors affecting wharf site selection for these projects,such as wave conditions,water depth conditions,sediment conditions,geological and seismic conditions,land site conditions,port support conditions,transportation mileage,etc.Then we put forward the site selection target based on the lowest sum of construction cost and operating cost as the evaluation standard,and summarize the site selection ideas and processes from the macro study of the primary selection to the scheme-level micro study of the final selection.Taking an investment project of Chinese enterprise in Malaysia as an example,we deduce the whole process of site selection,which can be used as references for the similar project site selection.
