AbstractThe subject of this graduation design is the schematic design of a 82000-ton bulkproduct carrier. What the designer mainly considers is the practicability of the ship and the economical point of view, we tried to reduce the cost of the ship construction. The whole design process covers most of the knowledge which the designer has gained from undergraduate taught courses. The design process can be divided into six major parts as follows:1. Fix the principal dimensions of the ship in accordance with the design specification and then check the capability. In order to select optimal schematic, the designer has taken three methods into account and chose the optimal one after comparison. Furthermore, the main characteristics of the ship are preliminarily checked.2. Design the lines of the under-water part of the ship using the method of “1-Cp”, while the up-water part is designed with the method of “Self-design” to correspond to the under-water part. The requirements of the lines of the stern must be considered in order to easily arrange a screw propeller and a rudder behind the stern.3. Consult similar ships to go along with the general arrangement. To make the ship to work normally and seamen to live comfortably, it is necessary to arrange every cabin and various related equipment properly. The frame space and the number of bulkheads are determined by corresponding rules.4. According to line gragh,we can calculate the hydrostatic curve. Calculation of Hydrostatics and Stability. In the calculation of hydrostatic and stability ,the designer obtains the hydrostatics curves. The initial stability for the four typical loading conditions, i.e. fully-loaded arrival, fully-loaded departure, ballast-loaded arrival as well as ballast-loaded departure are all checked based on the corresponding rules.5. Design a MAU-5 type of screw propeller using the method of “Draft design”. Ensure the cooperation of the ship, mainframe and the screw in order to enhance the velocity capability of the ship designed.6. Design the structure of cargo hold under the rules of “Rules For the Classification of Sea-going steel ships (2006)”. It is necessary to reduce the cost of ship construction on the premise of meeting the strength demands.Generraly speaking, the graduation project is a bulk carrier design as the basis, which considers the practicality and economy of the ship. The calculation and analysis are used to check whether the ship is sailing to meet the performance goals. I focused on the design of stowage and stability calculations and in this respect I also have done a detailed explanation of the calculation.Calculated by standardizing requirements and verification, the results of theship's design are with good ends so that it is good to meet the design specifications in the mission statement and the corresponding requirements of the performance.Key Words：Bulk Carrier;Linetype Design；Genenral layout Design；Stability; Structure Design目录摘要............................................................................................. 错误!未定义书签。
