Engine Room Top Platform Explored

Learn about the top platform of the machinery space of a ship

Introduction

We have been talking about the various platforms

of the ship engine roomand have discussed about

the bottom platformas well as the middle platform

of the engine room layout. Now it is time to get on

to the higher level and talk about the top platform

of the ship engine room. As usual, there are lots

of tanks, and other paraphernalia on the top

platform as well.

Take a good look at the sketch given below thissection to visualize better about what is being said

here.

Top Platform Layout

Spare Parts

The top platform contains the spare parts of main engine and spares for the operation of the ship including

the following.

Spare piston rod1.

Spare cylinder head2.

Spare cylinder liner3.

Spare propeller4.Spare tail shaft5.

This section will explain some of the paraphernalia found at the top platform.

Burning of waste oil, sludge, cotton waste is carried out using the incinerator .The waste oil which is obtained

from the scavenge drain tank, sludge from the purifier and oil water separator cannot be disposed overboard

so the incinerator is used to burn this oil. Plastic is not burnt in it because it would cause air pollution.

What is Hot Well?

Hote Well recollects the steam after the work is done and it is condensed. Boiler water tank is known as the

hot well because boiler feed pump takes suction from the hot well and gives it to the boiler through feed

check valve. It can be called by three different names, they are:

Hot well - because the water collected is hot1.

Cascade tank - because it collects the water from the condenser2.

Observation tank - because it is used for observe for any oil or dirt entering the system3.

If any traces of oil are found in the system, it indicates that there is a crack in the steam heating line in side

the fuel oil tanks. A sight glass is placed to observe the traces of oil or dirt present in the system.

If oil is present in the system then it forms a coating in tubes of the boiler, which may lead to lesser heat

transfer to the water in the boiler.

What is a Hydrophore System?

It is used to maintain the pressure of the water supplied to the different parts of the shipat various heights to

keep the constant presser of water in all lines and at all floors of the ship.

There are two hydrophore systems used on board:

Fresh water hydrophore system1.

Sanitary hydrophore system2.

What is the Jacket Cooling Water Expansion Tank?

Expansion tanks are provided for venting of gas, air or vapour formed in the jacket cooling water line, which

has to be released.

Expansion tank makes up the losses that occur due to evaporation in the jacket cooling space in the engine.

The make up water is provided in the expansion tank. It also provides the vent to trap any vacuum or vapour

due to evaporation or leakage /cracks in the closed cycle lines.

Low level alarm is fitted in the expansion tank to give alarm when the level of the water reaches the low line

due to leakage in the pipe or cylinder liner break down. Expansion tank also consists of a sight glass to

observe the water level in the tank.

WorkShop

WORK SHOP is present in the top platform it contains :

Lathe machine1.

Drilling machine2.

Grinding machine3.

Milling machine4.

Working bench5.

Bench vice6.

These machines are normally used for fitting and maintenance purposes and not for production obviously.
