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.
