In planning and designning of port and harbour facilities, it is very important to establish design condition of them on ship’s size of ships which would use the facilities.
　In many cases, the ship which would use the facilities couldn’t be specified, we should establish the standardized design condition on ship’s size by statistical analysis on the data of ships which would use the facilities.
　In this report, we made analysis on interrelation between Gross Tonnage of ship or Dead Weight Tonnage and the staple dimension of ship such as Length Over All, Moulded Width, Moulded Depth and Draft using the data of “Lloyd’s Register of Ships (1988)” and Register of Japanese Shipping (1987).
　On the analysis, we divided the ship to eight kinds, which were General Cargo Ship, Oil Tanker, Container Ship, Bulk Carrier, Gas Carrier, Pure Car Carrier, Passenger Boat and Ferry Boat, because recently ship would tend to be built for exclusive use on specified cargo transportation.
