Purpose

To explain and direct new engineering students about the process of drawing an engine system that exists on the T.S. Golden Bear(TSGB). A system is a series of components in order to provide a function aboard the TSGB, an example of this would be the jacket water system which cools the engines.

Outline

Materials:

Knowing what to draw

Organizing a tour

The tour

The final draft

Warnings

Cheating will result in a zero grade for that system, one out of the six that are traced.

Be aware of your surroundings. You are in the engine room with moving parts. DO NOT MOVE ANY VALVES OR TOUCH ANY BUTTONS! Doing so may result in harm to oneself or another.

Process

Materials:

Work blues or boiler suit and steel-toed boots must be worn in the engine room at all times!

Flashlight

EPO-120L workbook

Mechanical pencil

Engineering graph paper

Straight edge and/or ruler

Stencil with multiple diameters of circles ranging in sizes

Compass

Knowing what to draw:

In your Marine Engineering Systems Lab class, the professor will go over the system in detail so that you may have a better understanding of what you are observing. The EPO-120L workbook will have drawings inside of it that the instructor will go over that pertain to the system and will help you to organize how your drawing should look like on paper. The drawings in the workbook are not accurate so you do still need to go down into the engine room.

Organizing tours:

The corps of cadets (the student body) is split in to companies, and then into divisions, then into sections and then into squads.  The squad that you choose will have a squad leader that will organize a time to meet with the other people in the group so that each of you can go down into the ship and see what the engine room is like. Squad leaders may be hard to get a hold of because they too have to do homework and take classes. So, with this in mind, it is usually okay to just go with another group.

The Tour:

The tour guide, or squad leader, will take you into the engine room then start explaining what certain things are, and if you ask, they can explain what it does and how it works. However, chances are that the professor will force you to think of how it works in class. While the squad leader is talking you should be tracing on your pad of paper where you think it belongs on your paper as an accurate representation. Remember that you do not have to draw things to scale but you do have to have everything pertinent to the system including all valves, gauges and flow. Tours will start out with little to no expectation for you to know what you’re looking at; however, by the end of the class you should be able to trace the systems by your self and know what certain parts look like so that you may be able recognize it by the time that cruise comes around. During your tour, you will probably notice that it’s pretty messy and that your paper may have an oil stain or two. This is good because it provides authenticity and that you actually went down there and saw what you needed to as opposed to cheating. Also, your rough draft will have lines that go all over the place so don’t worry if you can’t figure out what one goes to; just remember to ask one of your class mates to make sure that you have everything.

The Final Draft:

After you confirm that you have everything in the right place, you will need to sit down in you room or some other place away from your other class mates because you don’t want your tracing to look like someone else’s. For your final you will need the engineers pad as well as the straight edge, compass, stencil, and fine point mechanical pencil to make your system look good. Be sure that you do not free hand anything over one cm (one box) so that nothing looks messy because you can and probably will be docked a couple of points. Once you think that you are done with the final, give it to an upper classman so that they may be able to look it over to be sure that what you’ve drawn is good enough for the graders. After you’ve made all necessary corrections, you’ll walk into class and place it on to the professor’s desk so that the professor can give it to the graders and points can be assessed.
