Marine Draughting

What you will learn

The Marine Draughting module enables you to work with a naval architect. Because we’re in Cape Town (the ship-building hub of South Africa) we allow you to specialise in this field over three trimesters.

Theory Section (Jan – Apr)

The marine draughting course at Academy IDT begins with eight weeks of theorical lessons.

We review the main vocabulary used in the marine industry and the different type of vessels, ships, yachts and boats. We concentrate on the basic knowledge needed to understand and be able to read technical drawings as well as knowledge of different structural parts of a ship from the details of the hull plating to deck structure. We also investigate the notion of displacement, the volume of buoyancy and basic calculations between displacement and the main measurement of the ship. Special attention is given to understanding the connection between density, volume and weight. We also spend time understanding weight calculations and calculating the centre of gravity for different types of beams, as well as how to bring the different weights together to get the final resultant weight and the centre of gravity of the ship.

During the theoretical session we also review the role of classification societies and international regulations.

Theory Section – FBSO Vessel (Apr – Aug)

After the first trimester we start the practical course with the AutoCAD plan of a section of an FPSO ship. Students are required to import the section into SolidWorks and re-draw the ship from there. Students model the hull, deck, deck-hull connection radius and the bulkhead shape using the hull and deck. Using information similar to an engineer’s sketch they produce the internal shapes of the bulkhead followed by the partitions, the horizontal frames and the beams. By the end of the 8th week we have built a full model of that section of the ship. In the last four weeks, students are divided into teams with each team building part of the ship. This allows the students to practice the type of team work they will experience in industry, with each group communicating and sharing information in order to find the correct connections between the parts of the ship.

Practical Section – Yacht (Aug – Nov)

The third trimester concentrates on yacht design. We start by modelling the engine drive train – students have to assemble all the drive train parts from the engine to the propeller. They then build the engine- bearing structure and finally, design the engine bearer. Part of the project involves solving the installation problem by creating the metal part.

Once this part is complete, students use the final four weeks to complete a group project. This project requires them to research different yacht designs, select one and model its deck on top of the existing hull given at the start of the course.
