摘要作为国际上设计制造的主要船型之一，散货船在运输市场上占据着很高的比重。本文是以南京汪洋船舶工程有限责任公司设计制造的8700DWT散货船为母型船，并基于NAPA软件进行9000DWT散货船总体设计。论文的完成对于散货船在相关领域具备更完善的资料有一定的帮助，同时本文也着重介绍了对于NAPA软件建模操作流程的相关讲解。58715

    论文主要涉及以下几个方面：

1. 通过上网搜索，查阅相关资料以及最新的新闻报导总结并分析散货船的发展现状、目前存在的问题以及未来的发展趋势；

2. 根据母型船的数据及相关规范对9000DWT散货船的主尺度进行确定，为NAPA的仿射变换提供数据支持；

3. 基于NAPA软件对本船进行船型建模、舱室划分、舱室定义以及载况加载，并利用NAPA软件的CAD出口应用CAD软件对船舶相应图纸及计算进行二次开发；

4. 依据《船舶与海上设施法定检验规则》并运用NAPA软件对9000DWT散货船进行静水力计算，稳性校核，干舷和吨位计算以及相关图表的输出。

Abstract As the design of manufacturing one of the main types, bulk carrier haye a very high proportion in the transport market . This paper is to Nanjing Ocean Ship Engineering Co., Ltd. design and manufacture of 8700DWT bulk carrier for the mother ship, and based on Napa software for 9000DWT bulk cargo ship general design. Paper for bulk carriers in related fields have some help with more perfect data . At the same time, this paper also introduces the Napa software modeling process.

This paper mainly involves the following aspects:

1. Through Internet search, access to relevant information and the latest news reports summary and analysis of the development status of bulk carriers, the current problems and the future development trend;

    2.According to the data of the master ship and the relevant specifications, the main scale of the 9000DWT bulk carrier is determined, which provides data support for the affine transformation of NAPA;

3.Based on the NAPA software, this ship carries on the model of ship type, the pision of the cabin, the definition of the cabin and the loading condition. The CAD software of CAD is used to carry out the two development of the corresponding drawing and calculation of the ship;

4. According to the < Statutory inspection rules for ships and offshore facilities > and the use of Napa software to 9000DWT bulk carrier of static hydraulic calculation, stability checking, free-board and tonnage calculation and outputting related graphics.

Key words: Bulk carrier; Main dimension; NAPA; Hydrostatic pressure; Stability check
