ter.Chapter 3 introduces theprogramming design language and the database visiting technology.Chapter 4introduces how to get data from AutoCAD two—dimensional graph.For users’convenience to use this software to carry on the computation,the paper carries on there—development to AutoCAD and realizes to read the data from AutoCAD and induct III 武汉理工大学硕士学位论文computing system’S database file automatically.Chapter 5 is about this computingsystem and COMPASS data transfer.The main idea of this chapter is to introduce thedatabase visiting technology and realizable method,as well as enter the data what isneeded in the intact stability computation from the COMPASS and induct to thiscomputing system.Chapter 6 is the development of an intact stability computingsystem WHUT-ISCS.The majority of this chapter introduces the loading principle ofthe bulk carrier,the intact stability computation as well as the development ofcomputing system. The core of this procedure design is the bulk carrier’S performance computation,the intact stability computation,and the ships’type,the loading condition and thenavigation area choice involved in the process of computation.The part ofperformance computation mainly includes the hydrostatic performance curve table,the Bonjean curve table and the stability interpolation curve table.The intact stabilitycomputation is mainly includes the metacentric stability,the dynamical stability andthe stability weighs.In the process of computation,various parameters’value hasgreat influence to the result,because the parameter computation involves lots oflinearity and the misalignment interpolation. The design of bulk carrier loading intact stability calculates software needs theauthor to have a firm professional foundation,acquaint with each link of lading,andhave the unusual understanding to bulk carrier’S loading.In consideration of thedemand of actual usage,this procedure adopts Visual Basic 6.0 as a platform,takesMS—ACCESS and MS-EXCEL as the main database,and takes ADO(ActiveX DataObject)as the database visiting technology.The procedure adopts the blockprocessing to handle different problems with mutually independent modules,in thisway the maintainability of the project approach is better.

二战后,由于全球对于散货运输的需求量大幅增加,散货船运输在海上货物运输中占据着越来越重要的地位,在货运总量中所占的比重也越来越大【11。
在国际航运业中,散货船运输占货物运输的30%以上。
IMO的调查显示,大宗散货运量近年来一直在持续增长,从2004年到现在,年增长率分别达到:5.9%,3.9%,3.9%。
由于货运量大,货源充足,航线固定,装卸效率高等因素,散货船运输能获得良好的经济效益,散货船已成为运输船舶的主力军。
现在全世界的原材料货物大多是由散货船承运的,因此散货船迄今仍然是世界性产业链不可缺少的重要的一个环节。
随着世界经济地不断发展,世界性的原材料运输必然增多,散货船运输仍将保持较高的增长势头,散货船的总吨数也必将增大。
目前,散货船正朝着双壳化、大型化、快速化和多用途化发展12】。
在新设计建造的散货船的使用年限将更长、更加环保而且自动化性能也会有很大的提高。
随着计算机水平的不断发展,散货船的设计方法也将不断地进步。
为了提高散货船的营运安全性,IMO、IACS等国家组织和各大船级社不断修改、完善SOLAS、MARPOL等规范、规则,提高船舶的技术
