FTV 1/25/2012 Engine Room Visit

A visit to the Engine Room is an awesome sight as we see the actual machines that work to make us sail through the ocean. It is here that we see how energy can be converted from one form to other to accomplish the tasks need to get the job done. 

This is a picture shows the actual fuel oil burners going into our Starboard (one on the right side of the ship) boiler. We have 2 boilers that make all of the steam that we use to make some of our electricity as well as some of our fresh water out of salt water. It is also used to turn our propeller.

This is a picture of our main shaft that runs from our engine gears all the way to the back (“Stern”) of the ship and out to our propeller. This is made up of eight sections which are bolted together. They are supported by bearings that have lube oil in them

These are our throttles that are in the engine room. These are opened or closed to put more or less steam to our engines to give the speed that the office on the bridge wants. The big one is the “Ahead” throttle to go forward and the small one is the “Astern” throttle to go backwards. The Red and Green dial at the top of this picture shows how fast the propeller is turning. The Red and Green dial below that shows us what the Bridge wants for speed.

As you work through this activity you will learn an important law of the universe that is the law of the conservation of energy, which states that energy cannot be increased or decreased, but energy can change from one form to another even as the total amount remains constant. Energy can be found in many forms here are some examples:

  • Mechanical
  • Electrical
  • Thermal (heat)
  • Chemical
  • Radiant (light)
