Due to the expansion of the circulation of commodities , many goods with the transport by sea and inland collaboration in the the Jianghai direct transport is such a way . Its connection to China's coastal , ocean shipping and inland water transport plays an important role in China , Jianghai ship has a broad development and application prospect . 2400 tons Jianghai nonstop cargo for the study, according to the ship's hull form characteristics , study for the optimization design methods and ideas , learn from domestic and international shipping to optimize research methods and design studies to optimize the ship . Has two main aspects : First, to optimize its structure . Uses the optimization method of the ship to the cargo tank area topside tank swash bulkheads changed straight bulkhead , this result makes cargo volume increases, easy loading and unloading cargo , but also increases large deck opening . Large deck openings increases will affect the ship's overall longitudinal strength and torsional strength , therefore , will have the strength check of the boat . Optimize the structure of the ship design , finite element model of the whole ship , created by MSC.Patran / Nastran software directly calculated according to the China Classification Society , \checking and analysis of the structural strength of the hull , in order to consider the real the ship sailed state response under various load conditions and wave conditions , and checking the large opening under the conditions of the longitudinal strength of the hull . The second is to promote energy conservation and it improved . Ship energy saving has become an important issue of the world shipbuilding industry and the shipping industry research , it is related to fuel and cost savings , environmental protection and economic benefits of the operation of the ship and other issues . As the shipbuilding industry and the development of the world economy , increasing oil prices , resulting in ship fuel costs were significantly higher trend , the share of the total cost of the operation of the ship expenses cost ratio . Ship propulsion energy-saving technology and methods have a lot to promote the application of energy-saving the ship , take a simple and practical method - to change the gearbox reduction ratio , to improve the efficiency of the propeller , the same power play host case, you can reduce the fuel consumption rate , to achieve the purpose of energy conservation .
