Lesson 1: Notions of MPP

What is MPP?

MPP consists of:
◦
Main propulsion equipment

◦
Auxiliary propulsion equipments
◦
Safety equipment
◦
Equipment of serving domestic requirement
◦
Deck ‘s equipment
Lesson 1: Notions of MPP
1. Main propulsion plant equipment
a. Main Engine

Generates mechanical energy to turn a ship's propeller

Kinds of following main engine can be used: Steam engine, steam
turbine, gas turbine, diesel engine, and “generator - motor”

Diesel engine is mostly used nowadays. Besides this, on modern
ships newly manufactured with large power, the steam turbine
propulsion plants are being developed.

In the marine propulsion plant, one or more main engine can be
used.
Lesson 1: Notions of MPP
b. Propulsion equipment
◦ Transforms mechanical energy of the main engine into thrust force
when maneuvering.
◦
The oldest type of mechanical propulsion for ships is Jet
propulsion.

◦
Paddle wheel was used on steamers until about 1850.
◦ Nowadays, screw propeller was used on all ship with advantage of
high efficiency and safe working.
◦
There are two common kinds of screw propeller used in the
marine propulsion plant, they are:

Non controllable - pitch propeller

Controllable - pitch propeller
Lesson 1: Notions of MPP
c. Driving equipment
◦
It is intermediate equipment to transmit power from a main engine
to a screw propeller
◦
Driving equipment consists of: Shafting, flanges, split muff coupling,
clutch, and reduction gear.
e. Main boiler
◦
Its duty is to supply steam (with high pressure and temperature) to
steam engine, steam turbine and other auxiliary machinery.
◦
Main boiler is used only on steam ship.
g. Conveyance equipment
◦
They are used to convey working substance to a main engine. They
consist of steam tube, gas tube.
