50,000-ton Large Hatch Multi-purpose Cargo Vessel Ship And Line Design

Hull principal dimension and lines design and research to 50,000dwt open Hatch Multi-Purpose Cargo Ship, depending on the design and development of the fifth generation big hatch multi-purpose cargo ship, has widely collected and analyzed the information which referred to the results of hull lines proof and optimization from other same kind ships of home and abroad, followed and understood the technique requirements and adaptability from world shipping, ports, waterway and cargo, optimized the principal dimensions and hull lines.To start with, the characteristics of the third and fourth generation ships were analysed. And the thought of principal dimensions and its design procedure of the fifth were given. Principal dimensions were demonstrated, the effects to deadweight, cargo deadweight and valid cargo deadweight cubic capacity from their length, depth, waterdraft and block coefficient were analysed. The relationship between hatch width and ship broads, length of cargo tanks, length of tanks, the relationship between general plan and ship dimensions, the relationship between dimensions and main properties like speediness, seakeeping, resistance and manipulation were studied.As a multi-purpose cargo ship, cubic cargo tanks are required as many as possible. So to define principal dimensions data and accomplish technique design procedure on the basis of the satisfactory that hull form should meet the above requirement, the test and measurement of resistance, self propulsion, flow line, flow field and seakeeping were carried out in Statens Skeppsprovningsanstalt, Goteborg Towing Tank(SSPA) in order to get the best hull form lines by comparative and optimistic analysis to the results of the above tests and measurements.In summary, this article expounds the dimensions study oriented to the fifth generation open hatch multi-purpose cargo ship and the achievement of a good selection to the length, broads and depth., such selection and hull line design, by optimization proof and comparing to other some kind ships, has been demonstrated to have excellent ship property and economy property.
