摘要我的毕业设计为4800吨近海油船总体设计。老师给的母型船资料为4600吨油船，所以我在设计中以母型船改造法为基本思想，同时专业课上的《船舶原理》，《船舶设计原理》等书也给了我很多的帮助，我以它们为参考进行设计。在设计过程中还要考虑了船舶的各项性能，如：稳性，快速性等。58704

在经过一番的摸索后，我把我的毕业设计内容分为以下几个重要内容:

一． 主尺度的确定——在看完老师给的任务书后，我借鉴母型船的数据初定主尺度，为了满足浮性方程，就要对主尺度进行调整，这样就可以进一步明确主尺度了，最后对相关性能进行校核就可以确定设计船的主尺度了。

二． 型线设计——先确定棱形系数和中横剖面系数及浮心纵向位置，确定进流段和去流段的长度来选择横剖面面积形状，通过1- 法对横剖面面积曲线进行改造，在绘制完格子线和轮廓线后绘制各站横剖线，后绘制水线半宽图，最终绘制纵剖线来得到型线图。

三． 总布置设计——根据规范并借鉴母型船的相关数据进行设计船的总布置设计，划分主体和上层建筑，分布舱室，填充设备。

四． 静水力性能计算——根据型值表计算船舶在静水中各种浮态吃水的各项性能参数，计算过程通过表格呈现。

Abstract

This topic of dissertation is the design of tanker of 4800ton oil tanker.

Parent ship data teacher is 4600 tons of oil tankers, so I designed to parent ship transformation method is the basic idea, and "Ship Principle" courses on "Ship Design" and other books also gave me a lot of help I to design them as a reference. In the design process also took into account the performance of the ship, such as: stability, fast and so 

After some exploration, I put my graduation project is pided into the following key elements:

First. Determine the main scale - after reading the book task teacher, I learn from the mother vessels of the main dimensions of the data initially, in order to meet the buoyancy equation, it is necessary to adjust the main dimensions, so that you can further define the main dimensions, Finally, the relative performance can be checked to determine the main dimensions of the ship's design.

Second. Form design - first determine prismatic coefficient and the cross-sectional coefficient and center of buoyancy longitudinal location, determine the length of the inflow section and the flow section to be selected cross-sectional area of the shape of the cross-sectional area of the law by 1- curve transformation, after drawing after drawing the grid lines and the cross-sectional contour line of each station, after a half wide picture drawn waterline, eventually drawing a vertical line to obtain cross-sectional profile in FIG.

Third. Layout Design - design of the ship according to the specifications and reference data relevant parent ship general arrangement design, piding body and superstructure, the distribution chamber, filling equipment.

Fourth. Hydrostatic Performance Calculation - calculate the performance parameters of a ship in calm water of various floating state according to the draft table of offsets, via a table showing the calculation process
