The water area and handling facilities of coal terminals depend on dimensions of bulk carriers, which are performing ship calls to marine ports. Dimensions and maximum deadweight of bulk carriers tend to increase as a result of «economies scale» effect and dynamically inequable shipbuilding market. Maximum parcel sizes of vessel has been increasing every decade. That makes impact on the configuration of the terminals, the volume of construction materials and dredging, marine terminals scheduling. For an accurate design or exploitation of marine terminals there is a need for updating (every 2–3 years) of vessel dimensions by using methods classification, benchmarking and approximation. The article specifies the classification of bulk carriers by vessels deadweight and regional categories and presents a detailed structure of the global dry bulk fleet (quantity and distribution for existing and planned for construction vessels, which are registered by IMO International Maritime Organization), which allows more deeply consider the current status and trends in the shipbuilding industry. For coal bulk carriers the dimensions were updated (length, breadth, draught, number of cargo holds) by every 10 000 tons of deadweight at level of 95% provision, for the first time in the practice of Russian researches obtained approximating dependencies between dimensions and deadweight. It is concluded that further approximating dependencies can be included into a mathematical apparatus of integrated simulation models for marine coal terminals, which are specified with the stochastic distribution of ship calls. Actual dimensions of vessels can improve the accuracy of the design, it can be applied at all stages of the design (conceptual design, project documentation, working documentation), as well as for planning of cargo handling operations and ship calls for current operating activity.
