Take the accuracy control as an example. It is clear that the current accuracy control is not so satisfying or not so suitable for the development of shipbuilding at the present stage. Therefore, we should change and modify it so that we will get good shipbuilding qualit with little enegy and have the initiative in industry competion. The designed ship is a kind of steel, single-deck, double-bottom hold area, double-shell structure side, single-propeller, single-rudder, single-engine, diesel engine-driven, 37220DWT bulk carrier. It has bulbous bow, forecastle, stern poop and five cargo holds. Bulk carrier is refered to a kind of ship used to carry grains, coal and ore sand. It can be classfied into large bulk carrier and mini bulker. The large bulk carrier often carry plenty of commodities in a long distance, and it is usually suitable for ocean transportation, while the mini bulker is used to carry goods in a short distance, and it is always s
