During The course of B.Tech Marine Engineering, there is a subject with the name MAM which teaches us the foundation of Marine Machinery. Meaning It teaches us about the machine’s principal, it’s working and other application of those Machines.
So today under this article we will be talking about what are the main topics which are taught in MAM subject. Normally according to the Course Planner this subject comes in 3rd Sem of 4-year Program. So if you are already passed 3rd sem I am pretty sure you already know about these.
Let’s get started…..
(1) Engine Room Layout
Out of 24 hours, Engineers onboard have a minimum duty hours of almost 8 hours in the Engine Room of the ship. So we should be knowing about the place where we are going to work and spend our most of the time there. So Engine Room Layout will familiarize you with the sitemap of Engine Room i.e the placement of the machines and tools inside the Engine Room. Ofcourse we will be studying about this in deatils in some other post.
We are also taught about the tools which we use in the Engine Room like Crane and lifting equipment, weilding equipment and Hydraullic Equipment etc..,
(2)Evaporators
By the name we can guess that the machines which converts the liquid state into vapour state is known as Evaporators. There are tons of types of evaporators and we use them on the basis of our requirement. Machines like Fresh Water Generator, Boiler and etc.. uses evaporators as their primary functions. So Studying this topic involves the selection, types of Evaporators. And ofcourse we humans have the tendency to extract the maximum output of any things so we will also study about How can we maximise the output of Evaporators?
(3) Distillation, Purification & Sanitization
All of the above word meaning is same and that’s cleaning something. Onboard the ships we require machines that can seperate slug from oil, salt from sea water, & can sanitize the sewge waste so that it can be discharged into sea. There requirement are fulfilled by Purifiers, Clarifiers, Fresh Water Generators, Seawge Treatment Plant, Incinerators and more.., So in this we will study about the working and application procedure of these Machines and ofcourse their maintaince. All of these machines will be dicussed one by one in upcoming posts.
(4) Pump & Piping System
Just like blood vessel is in the Mammal’s Body, there is Piping System on the ships which carries fluids from one place to other based on our requirement. And in order to make something flow(unnaturally) we need Pump that can provide enough energy in order to make the fluid flow. So we will be also taught about Pump and it’s Piping System with all it’s parts and maintaince procedure.
(4) Compressors & Blowers
I am pretty sure that you will agree with me that if I say that we can’t start the Main Engine without the use of Air compressors. Let me know about your thoughts in comments section below.
There are many types of Compressors available which we use on basis of our requirement. So inorder to select the right compressor for the right job one must know the features of these. So we are also taught about the Compressors and blowers. You should know that these two are not very different.
(5) Dry Docking
Dry Docking is same as we are putting our car in a garge for servicing. It is done periodically to check & repair the hull of the ship. And also SURVEY is done while Dry Docking Period. Surveys are also done periodically in order to check whether the ship is in condition to sail in an efficient way or not and also certificate is issued after survey is done which shows the efficiency of the ships and is very important at time of issue of Insurance Policy. There are tons of Survey and Certificate that are issued to a ships we will discuss about that later.
(6) Deck Machiney
Engineers are responsible for efficient operation of machines onboard the ships whether its in or out of the Engine Room. There are machines on the deck like Windlass Machine, Capstan, Cargo Crane, etc. So all these also comes under the Engineers watch. So we are also taught about their working and maintaince procedure of the Machines on Deck.
(7) Safe Manoeuvring
Moving a ships is done by combines working of Machines onboard. Like Main engine produces power which rotates the propeller and the ship move and the direction is given by steering gear to the rudder.
So in this section you will taught about Propeller Shafting, Steering Gear, Stabilizers, Rudder, Bow thrusters, Anchors and more. In one word all the equipment which helps in safe manoeuvring is taught to us so that we can work efficiently onboard the ships.
I think that the best book for this subject is Marine Auxiliary Machinery H. D. McGeorge— You can Buy From Here
From my point of view I tried to cover all the thing if I didn’t Pls feel free to point out.
