AEM - The Science of Ship Design
Synopsis of Advance Elective Module (AEM)
The Science of Ship Design
The aim of the module is to provide students with an understanding of the marine offshore industry, focusing on the fundamental concepts of naval architecture. Hands-on will include boat modelling, field visit and mini projects to enhance learning.

After attending the 4 days AEM, we would like you to submit a reflection of your experiences. Your reflection should cover these 3 broad areas:
3 - Describe THREE things that you have learnt from the AEM experience
2 - Describe TWO things that you like about the AEM experience.
1 - Share ONE thing that we can improve on the AEM experience.

ReplyDelete3 things learnt:
- How ships are able to function and float despite being made out of heavy materials.
- The many factors that can affect the speed of the ship such as how streamline it is or the density of the fluid is it travelling through. This can also be applied into our final ship model.
- The testing of the ship before ship launching to see if it floats by using different tests like the inclining test and sea trial.
2 things I liked-
- Being able to learn a new topic under the watchful eye of the instructors at Ngee Ann Poly and the amount of hands on work there was really fun and I felt accomplished after our model was built.
- Being posed a challenge that we had no exposure to previously such as needing to built a ship out of layers of compressed styrofoam.
1 thing to improve.
- Make it longer as I really enjoyed myself and would hope it was longer.

ReplyDelete3 THINGS I HAVE LEARNT:
-The name of different parts of the ship and the ship's geometry which keeps it stable
-How the ship managed to float although being made out of denser materials
-How the heavy ships are 'launched' into the sea after building it on land
2 THINGS I LIKED:
-Being able to build a boat by ourselves proved to be a challenge for all of us which we all enjoyed
-The sense of achievement after seeing our boat afloat with all the weights stacked on it
1 THING TO IMPROVE:
-To be given more time for us to build our boats and to be able to experience more of poly life
Tan Xin Yu:
ReplyDeleteIt is a great experience! I have learnt a lot of wonderful things about ships. I learnt about the parts of the ship, what are the things need to be checked when making a ships and what affects the ships to sink. This AEM experience also helps me to make new friends and taste delicous foods in ngee ang poly. There are also tea breaks that i alway looking forward to. I hope this AEM can have more days as i really enjoyed myself.

3 Things I have learnt:
- Ships are able to float on water is due to Archimedes’ Principle, which states that if a body is immersed in a liquid there is an apparent loss in weight. This loss in weight is the upthrust exerted by a liquid on the body and is equal to the weight of the volume of liquid which the body displaces.
- All newly built ships have to go through an Inclining Test before one can use the ship to set sail. This test is to determine the ship’s stability, light-ship weight and the coordinates of its center of gravity. The inclining test is applied to newly constructed ships greater than 24m in length, and to ships altered in ways that could affect stability. These newly built ships could also go through a Sea Trail, which is usually the last phase of construction and it takes place in open waters, and it can last from a few hours to many days. Sea Trails are conducted to measure a vessel’s performance and general seaworthiness. Testing of a vessel’s speed, maneuverability, equipment and safety features are usually conducted. The Sea Trials include tests such as speed trial, crash stop, endurance, maneuvering trails and seakeeping for the ship.
- I also learned about the resistance and the propulsion of ships. The ship propulsion is one of the most important considerations for a naval architect is the power requirement for a ship. The power required enables the naval architect to select a propulsion plant, determined the amount of fuel storage required and refine the ship’s center of gravity estimate. Examples of such mechanisms are paddle wheels and propellers of different forms. Testing of full-scale ships and models determined that the power required to propel a ship through the water was directly related to the amount of resistance a hull experiences when moving through the water. Examples of power are brake horsepower (BHP), shaft horsepower (SHP), delivered horsepower (DHP), thrust horsepower (THP), effective horsepower (EHP). Ship resistance (Total hull resistance RT), is a force which opposes the movement of the ship. The total resistance of a ship is made up of a number of different components, which interact one with the other in an extremely complicated way. The total resistance is made up of four main components, frictional (viscous) resistance, wave-making resistance, Eddy resistance and air resistance. The resistance of a ship must be overcome with a forward thrust, supplied by some thrust producing mechanism.
2 Things I Liked:
- I like being out of my comfort zone as it challenges me to improve in my weaker areas. Constructing a ship model and accomplishing it was really an eye opener for me as I realised that I have far exceeded my expectations of my skills.
- The Ngee Ann Polytechnic Marine and Offshore Technology teachers are very kind to us and are willing to help us when in doubt. The Advanced Elective Module (AEM) has also allowed us to forge stronger bonds with our friends.
1 Thing To Improve:
- Increasing the number of days of the Advanced Elective Module (AEM)

ReplyDelete3 Things I have learnt
- I have learnt that all ships and vessels have to go through a test called the SEA TRIAL. Sea trails are conducted to measure a vessel's performance and general sea worthiness.
-I have also learnt the different types of ship launching.Some examples of ship launching are airbag launching,mechanical type launching and gravitational type launching.
-I have also learnt the ship's geometry and terminology
2 things that i like about the AEM are...
1)We were able to design and create our own boat from scratch which was very fun
2)Able to experience the polytechnic life the as we bonded better with our friends
1 thing that the AEM can be improved by is....
1) The AEM course could have been longer as it was very fun and engaging.
