在设计过程中，主要参考母型船，同时以《钢质海船入级规范》2006，《船舶设计原理》等参考文献进行设计。

毕业设计内容主要包括以下几个部分：

一、主尺度确定——根据任务书的要求并参考母型船，初步确定主尺度，经过重力与浮力平衡进一步确定主尺度，再对舱容进行校核，最终确定船舶主尺度。

二、型线设计——采用母型改造法，绘制设计船的水线半宽图、横剖面图、侧视图，从而得到设计船的型线图。

三、总布置设计——按照规范要求并参考母型船进行总布置设计，布置舱室和设备。61820

四、结构设计——本船全船为纵骨架式，参照相应规范计算船体各处构件的相关参数如剖面模数，总纵弯曲等，选取构件，保证结构设计的合理、船体结构的稳定。

4900DWT oil tanker structural strength design

School of Naval Architecture and Civil Engineering, Zhejiang Ocean University, Zhoushan, Zhejiang 316004

[Abstract]The graduation design is a structure design of 4900DWT oil tanker.During the design process, with reference to the mother ship, at the same time,take 《The Standard of Steel Quality Sea-going Ship into Class whit Calculation》, 《the principle of ship design》 etc. as references for design. 

Graduation Project includes the following sections:

First.determine main dimensions– According to the requirements of the task,reference book,consider type ship initially identified the main demensions.Taking the balance of gravity and buoyancy to further determine the principal dimensions, and then checking performance such as volume.Finally, ultimately determine the principal dimensions of the design ship. 

    Second. type design–The parent type transformation method, draw the design of ship's water line half-width plan, midship section , outboard profile, in order to get the design of ship-based moulded plan.

Third.general arrangement design–in accordance with the Calculation requirements with reference to the type ship to carry out the design of general arrangement, the main pisions and the superstructure of ships, ship compartment layout and equipment. 

    Fouth.structural design–the boat ship-wide framework for the longitudinal type, calculated by reference to the hull of the corresponding norms of the relevant parameters in various components such as section modulus and so on, select the components to ensure the reasonable structure design.
