摘要

本次畢業(yè)設(shè)計為2500噸油船設(shè)計

在設(shè)計過程中主要參考2400噸油船為相近的母型船，同時以《鋼質(zhì)海船入級規(guī)范》2006，《船舶設(shè)計原理》等文獻為參考進行設(shè)計。在設(shè)計過程中綜合考慮了船舶的快速性、操縱性、經(jīng)濟性等性能。

畢業(yè)設(shè)計內(nèi)容主要包括以下幾個部分:

一． 主尺度確定——根據(jù)任務(wù)書的要求并參考母型船初步確定主尺度，經(jīng)過重力與浮力平衡進一步確定主尺度，再對容積、航速及穩(wěn)性等性能進行校核，最終確定船舶主尺度。

二． 型線設(shè)計——采用1－Cp法改造母型船型線，通過繪制輔助水線半寬圖來繪制設(shè)計船的水線半寬圖、橫剖面圖、側(cè)視圖，從而得到設(shè)計船的型線圖。

三． 總布置設(shè)計——按照規(guī)范要求并參考母型船進行總布置設(shè)計，區(qū)劃船舶主體和上層建筑，布置船舶艙室和設(shè)備。

四． 性能計算——對設(shè)計船的裝載情況、浮態(tài)、初穩(wěn)性、完整穩(wěn)型等性能進行校核，包括靜水力曲線、穩(wěn)性橫截曲線、靜動穩(wěn)性曲線等相關(guān)曲線的繪制，以滿足任務(wù)書及規(guī)范的要求。

五． 螺旋槳設(shè)計——設(shè)計螺旋槳的直徑及其他參數(shù)，保證船、機、槳三者的配合，以提高設(shè)計船的整體性能。

    關(guān)鍵詞：油船；主尺度確定；型線變換；性能計算；螺旋槳設(shè)計

Abstract

This topic of dissertation is the design of tanker of 2500ton oil tanker.

During the design process, the main reference for similar 2400ton as type 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. During the design process, I has considered the ship's speed, maneuverability, economy, performance, etc. 

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, speed ,stability and so on. Finally, ultimately determine the principal dimensions of the design ship. 

Second. type design-Useing 1-Cp-based law reform typer ship line drawn. Through drawing the water-assisted semi-wide plan to draw the design of ship's water line half-width plan, midship section，outboard profile，norder 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 divisions and the superstructure of ships, ship compartment layout and equipment.     Fourth, performance Verification – Considered the loading of the ship design, the floating state, the beginning of stability, integrity , stability and other performance-based verifications, including Hydrostatic curves transversal stability curve, static and dynamic stability curve of the drawn curve, etc., to meet mission requirement and Calculation

Fifth, propeller design – determine the diameter and other parameter of the propellers to ensure that ships, aircraft, propeller with three in order to improve the overall performance of the design of the ship. 

Sixth, 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.

Key words：oil tanker ；principle dimension ；transformation in line ； function calculation ； propeller design
