To meet the stringent national requirement for protection of environment, FHC has proposed a design of silo with better enclosing feature instead of exposed coal stockyard forsthe Phase 3 Coal Terminal at Huanghua Port. As it is the first time to use silos on large scale in coal terminals of China, many technical issues need to be solved by researches and studies. The present paper introduced the determination of silo size by using computer simulation model, by giving practical examples in the engineering practice. The paper has also discussed design study of slewing ship loader for loading vessels at both sides of the coal berth.
