摘要近年来，中国经济处于持续增长的阶段，对于货物运输存在着极大的需求。沿海水运相对陆运和空运，其运价更低且载货量更大，往往达到万吨以上，同时可以满足长距离运输的要求，具有一定的优势和发展前景。目前，沿海货船使用最多的种类是干货船，这类船型一般可以装载不同种类的货物，如杂货、集装箱、散货等，因此其对国内货物运输市场的适应性更强，更具生命力。
鉴于上述，本文运用专业的船舶设计软件NAPA，进行125.6米沿海货船的总体设计。首先，对沿海干货船的发展现状与趋势进行了概述。之后，根据母型船换算新船的主要要素，并进行浮性、快速性、初稳性及舱容校核，初步估算船舶重心、空船重量、载重量。然后，基于NAPA完成新船的型线设计、舱室划分及基本载况的加载，计算新船的静水力性能和完整稳性，并绘制型线图和总布置图。58699
设计船型为沿海干货船，船首为球首型，船尾为双尾型，采用双机双桨，船体为双壳双底结构。相关性能的计算与校核，依据中华人民共和国海事局发行的《国内航行海船法定检验技术规范》。

Abstract
In recent years, China's economy is in a period of sustained growth, there is a great demand for goods transport. Coastal Waterway relative land and air, the lower freight and cargo capacity larger, often reaching million tons or more, and can meet the requirements of long distance transportation, has certain advantages and development prospects. At present, the coastal vessel using the most species is dry cargo ship, the ship can generally be loaded with different kinds of goods, such as cargo, containers, bulk cargo and, so its adaptability is stronger for domestic cargo transportation market, more vitality.
In view of the above, this article uses the professional ship design software NAPA, carries on the 125.6 meter coastal cargo ship general design. First of all, the development status and trends of the coastal dry cargo ship were summarized. After that, according to the main elements of the new ship, and the floating, rapid, initial stability and cabin capacity check, the preliminary estimate of the weight of the ship, the weight of the ship. Then, based on the NAPA to complete the new ship line design, compartment pision and the basic load conditions, the calculation of the new ship's hydrostatic performance and complete stability, and draw the line and general layout.
Design of ship for coastal cargo ship and bow to the ball first, twin skeg stern, adopts double sculls, the hull was double bottom double hull structure. The calculation and check of the performance related, according to the maritime safety administration of the people's Republic of China issued by the domestic voyage ships statutory inspection technical rules.
