You guys asked for it, so here’s the 360-degree tour of the engine room.
The engine room is hugeeee, like ginormous compare to bridge or lifeboat which means
there’s a lot of sections to cover, so ill be highlighting the important machinery and
their uses, then quickly moving on to next section.
Pause or rewind a bit if you want to explore more.
If you’ve never been on a mega ship, the layout can be a bit disorientating, I almost
got lost when I was a fresh cadet.
Don’t try too hard to map out the layout, just know that the Engine Room has total of
5 deck levels and ill mention whenever I go down one level.
Anyways we’ll starts from the engine control room which is on the upper decks.
Most of the systems are remotely linked to the control room, and rightfully so, since
most operations are remotely controlled and monitored from here.
The most important one is perhaps the ICMS Cabinet at the back, all machineries and systems
on the ship are linked to this centralized computer, they are processed and remotely
displayed for other systems.
Through the fire door into the actual engine space.
The Vertical Oil boiler is for producing steam needed for heating fuel and lube oil.
An onboard Incinerator for burning general garbage.
Moving ahead we can see the controls for incinerator.
And now we will head down to the 2nd Deck.
Through another fire door we are inside the electrical circuit room where the temperature
is maintained at a cool level for all the circuits and computers.
It’s mostly transformers and starter controls for reefer containers, lights, pumps, fans
and generators.
Outside the electrical room behind the cage we can see the actual 6600 volts transformers.
the frequency convertor is used to convert alternating current; you know AC power.
Waste oil settle tank for boiling out water content in waste oil
Moving forward, we have sterilizer for our fresh water.
Big bottles of Refrigerant to refill air conditioner.
Up top is one of the many air vents that provide ventilation throughout the engine room.
If we are in tropical zone like Singapore the temperature be quite hot, up to 45 degrees.
From here we have a better angle of the air conditioner unit.
Calorifier for heating water.
We have 4+1 air compressor on the ship, this is the “plus one” separated from the other
four in another area.
The white box is a cylinder oil measuring tank.
Finished 2nd deck now and let’s head down to 3rd deck.
Here we have our Fresh Water Generator and the cooler Pump; the cooler is down below
which we will pass by later.
Shifting forward, here’s the rest of the 4 air compressors; the compressed air is transferred
and stored into the two big air reservoirs behind.
The main valves are for main engine while the smaller ones are drain valves for collected
moisture.
Coming back around, we are in front of the workshop’s entrance , the elevator door,
and a side profile of the main engine.
Above us there’s one of the many monorails that run across the entire engine room, its
used to lift heavy parts around.
Going inside, heres our electrician officer.
All around, you can see there’s big tools, small tools, power tools.
Tools, tools everywhere.
Next room is the spare stores which we have everything like all sizes of bolts nuts, coupling,
gaskets. we are very well stocked.
Coming back to the main area, finally we have the 12 cylinders in sight.
Downstairs you can see the engine cadet checking on gauges and recording logs.
The big tubes up top are the exhaust manifolds which runs up to the funnel.
Behind is a small bathroom.
Moving next to one of the exhaust valve and cylinder heads, the thick tube is a high pressure
lube oil line.
Over the edge on the side is the top part of spare cylinder liners which we will check
out later once downstairs.
Now Smack in the middle of the engine, we have a clear view of the 3 smaller lines which
are for fuel injection.
Going around to the side, this is the turbo charger for that extra power.
For those that don’t know, turbo charger re-uses the exhaust to produce more power,
similar to cars.
The other tubes on the starboard side is exhaust manifold from the generators.
Walking behind the engine we are now in between two turbo chargers
The smaller pipes are lines for air intake and jacket cooling
Down into 4th deck, here we have a spare cylinder head, exhaust valve, a sea water pump for
jacket cooling and sewage treatment tank for use at ports and coastal waters.
Into a small sub section, we have four diesel generators.
The opposite side is the central cooler for all cooling systems including Main Engine
jacket, generators and our fresh water.
If you remember previously the cooler pumps is actually located right above deck.
Walking pass the spare cylinder liners, it’s quite big.
This is one level below the cylinder heads; it’s called the main engine local control.
From here, Engineer they can do manual throttle adjustments in case of emergency, say for
example telegraph not working.
Which is why there is an internal telephone to communicate with navigation bridge for
receiving engine orders.
This is the purifier room for diesel and fuel oil, its purpose is to remove impurity before
injection into the main engine.
It’s one of the hottest areas in the engine room
Finally we have arrived at the fifth and lowest deck – we call it engine floor.
Here we can see the entirety of the crank case with individual crank case door for maintenance.
Tons and tons of miscellaneous pumps and valves all around.
Shifting forward to the front of the crank case we have two pumps supplying lube oil.
Opposite side is the essential pumps including general service and ballast pump which is
vital for deck side operations.
You might notice the red hatch at the back, that’s the entrance down into the duct keel
which I’ve explored in an earlier video
Going around the crank case, this side doesn’t have the same crank case doors, instead it’s
a series of relief valves for in case of an emergency to release pressure.
Here we have more purifiers but not for fuel or diesel, these for specifically for lube
oil.
Finally we arrived at the shaft, between the crank case and the shaft is a massive flywheel
for counter balance.
On the other end is a shaft generator for producing electricity from the spinning motion.
The oily water separator is vital part of Marine pollution code; its purpose is to filter
oil content within dirty water so that it is clean to discharge.
At the
very end of the engine room we have a bulkhead and behind it, is the stern tube.
Pressure gauges used to monitor the tube seal to ensure water-tightness.
The Emergency escape is just around the corner.
You climb up from here and pop out onto the open decks.
And we’ve covered most of the engine room.
As you can tell its massive so the tour is a bit long winded but hopefully you find it
interesting.
