As-salamu alaikum and Welcome back to Orange Shots
most of you have asked the same question time and again
have you ever repeated the Titanic scene on our ship
We have done it so many times ...
especially when we were young and it was early days in the merchant Navy
we used to enjoy doing it
we used to spread our hands like this
RAKESH!!!!
Today we will talk about at least three of the things that
are at the forward part of the ship and are very important ..
Today we will start with the bow of the vessel
bow is the foremost part of a ship
various equipments are fixed over there
but let me show you a very interesting thing first
this grey area that you see behind me
this is all rain
I'd literally have to run if it comes here
this part of the bow is also called Foc'le
there are various parts of it
there are a couple of very interesting things outside the Foc'le of the ship
the first interesting thing is called bulbous bow
on a loaded ship this part is submerged
you can see this (bulbous Bow) only when the vessel is in ballast
otherwise you cannot ..
Bulbous Bow has a very important function..
just like the aerodynamics are important for the airplanes
the water dynamics are very important for the ships
bulbous bow helps a vessel Cut through the water
seawater has friction
as seawater is liquid, it has got certain friction to it
and it resists anything that cuts through it
this bulbous bow helps fight that friction and resistance
you guys must've seen this in many ships before
but if you guys didn't know before what it was...
Now you know..
Second thing that I would touch upon is the flare
of the BOW..
the flare is slightly protruded and raised ..
it is extended up to the main deck at an angle and then there is bulkhead
It has its own purpose
in this clip a ship is pitching heavily and it appears that the bow
is getting into the water and then coming out
but as the ship has a flare in the forward part
this flare causes the water to splash away
once the bow slams on the water.
and that's why the water does not come on ship
and just like every natural thing, Water is powerful
Consider the example of storms to understand this ...
The water is extremely powerful & forceful ...
The flare prevents the water from coming on board
and hence prevents damages to ship
and protects the ship from the force of water
now that we have already seen all the things that are outside of the bow
Now it is time to talk about one very important thing
you guys must've seen in the movies
or must've read in the stories
-- the vessel being at anchor --
or seen the ships dropping anchor in the videos and movies
that anchor my friends is this ..
the rain is getting close ... anyway ..
Let's talk about the anchor, we have two anchors
One is on the starboard side of the ship
and the other one is on the portside of the ship
an Anchor is a truly amazing equipment
we should also discuss
how such a huge vessel is held up by such a small anchor
the actual size of the anchor varies
it depends upon the size of the ship it is actually fitted upon
an anchor is actually quite big in itself
but if you compare it to the size of the ship it is fitted upon
It is truly truly tiny in comparison
consider our vessel -- we are usually loaded with 150,000 tons of cargo
add 20 to 30,000 tons more
that means around 180,000 tons weight is held up in position
by a seven or eight tons anchor
the anchors of different ships are of different sizes
if you talk about our Vessel, then have a look at these links
I am not a small Person ..
I am about 5'10" high and these links are positioned higher than me
this machine that lowers the anchor in the water is called Windlass
the chain is wrapped on the drum of Windlass
and the outboard end of the Chain is connected to the anchor
and the inboard end is stored in the chain locker
it seems like there is a good news for me ..
this rain did not affect us and it's blown away
all this whitish area is rain
thankfully it hasn't affected us
on the main deck I showed you the anchor and Anchor Chain
which was very long
the length of one shackle is 27.5 m
and we have around 12 to 13 shackles
naturally you may be asking about their storage ??
These huge round Pipes that you see
are called chain lockers
The Chain that is connected with the anchor
is stored here after passing over windlass
All the excess chain is stored inside these
we have one of these pipes on the Starboard side and the other on the Port side
or -- one on the right & one on the left
that's where it is
but it's truly amazing
that such huge ships are being held by such small anchors
now .. why do we use anchor
our ships usually call different ports
but there is a thing associated with these calls
just as an aeroplane has to pay when it stops at an airport
We have to pay for the stoppages at ports as well
especially if we are going at a berth or at a paid Anchorage
but when we find suitable depths at open seas ...
As the seas and oceans are huge
We do find suitable depths at many places at open seas
we can drop anchor there & wait for our next voyage
or wait for the next employment, free of charge
your anchor is your friend at these times
this was just one purpose of Anchor
there are many purposes of an anchor
it is used in various types of moorings as well
apart from this, if you lose manoeuvrability of your ship
or if you lose your main engine
your last resort is to drop anchor
not always but it helps a lot
furthermore I told you that we have two Chain lockers
one was that one and the other one is right here
how does an anchor hold a ship ?
When we are dropping our anchor ..
The chain is usually paid out from the windless and is leading vertically down
due to the weight of the anchor, the chain is hanging vertically
You keep paying out the chain
and a time comes when Anchor touches the Ground.
A ship's anchor has a few very important parts
One is called Shank, that is the solid backbone of anchor
and then there are two flukes that helps the anchor dig into the ground
at first when the anchor touches the ground it is lying flat
and then you keep on paying the chain out
that is you lower the chain even more
and then the ship starts moving in a certain direction
The chain forms a slight angle from the ship
this slight angle causes the shank of anchor to raise up
due to the movement of ship the anchor that is lying flat on the ground moves as well
The angle between the flukes and Shank is increased even more
and then due to the movement of the ship
these flukes dig in the floor of the sea
after digging in it becomes easy for anchor to hold the ship
you can easily guess one thing that is important in this mechanism
and that is the importance of speed of your vessel
Your Speed should not be excessive once you're dropping anchor
the common perception that you can drop anchor at any speed is wrong
in last days we talked about crimson Polaris and we talked about Heng Tong 77
one thing was common in both accidents
the anchors were dropped when the ship was moving with considerable momentum
as a result the Chain was broken and the anchors were lost
as per my opinion the speed of the ship should not be
more than one knot when you're dropping the anchor
and at the same time your engine should be running
busy in reducing the speed of the vessel
this is really really important
and if you do not comply with this, your anchor may be lost
we have one anchor that I showed you on the port side
this is the second anchor
this is on the Starboard side or the right side of the ship
at the same time you also have to ensure that the weather is not bad while at anchor
because in case of bad weather the sea, swell and wind -
all will push your ship
remember as we have discussed a few moments ago
that an anchor is very small in comparison to the ship itself
an anchor can hold a ship but only in normal weather conditions
when excessive force is applied on the ship while
your anchor is already dropped & with ship holding onto her anchor
due to the movement of the mammoth ship the anchor may be lost (probably)
I have uploaded 2 videos about Storm
in one of the videos I told you guys
that we were an anchor and the storm was coming towards us
in that case we heaved up our anchor before the arrival of Storm
because we did not want to endanger our Anchor
and until the time the storm persisted
we used our Main Engine to manoeuvre the vessel
because ships engine is the
only thing that can support a ship in any kind of conditions
it is designed to run this mammoth forward and aft in any weather conditions
you should not leave your anchor at the ground during the storm
There are a couple of things that you have to think before dropping anchor
if you're thinking that you can drop Anchor anywhere,
in any part of the world Then you are wrong
you have to ensure that the depth where you are dropping the anchor is suitable
secondly the holding ground should be good
Again I would like to quote example of Heng Tong 77
she is surrounded by sand, and Sand is a very bad holding Ground
and so are the shoals, shingles and a like
The anchor will keep dragging if such is the holding ground
As the weight on Ship will keep increasing, the anchor will keep dragging
except, if there is no other solution
you should avoid dropping anchor at such spots
Thirdly, as I mentioned moments ago - you should avoid bad weather
if the wind force is already excessive don't drop the anchor
we are usually advised to be careful when the windspeed is around 26 knots
and if it increases to 35 to 40 kn
the anchor should be heaved up.
don't put your anchor and your ship at Risk.
if you want to know these wind speeds in kilometres per hour
26 knots is approximately 40 KMPH
and 35 to 40 kn comes to approximately 74/75 km/h
such wind speeds can generate the sea and swell
these are very important things that you have to take care of
anchor is very helpful to a ship but it has its own limitations
and we have to give due considerations to all of these limitations
meantime if you guys want to know how much money is required to run the ship
then that Video will be linked here
and if you guys want to know how does a new Cadet feel
and what is his routine
than that Video will be linked here
take very good care of yourself
and remember me in your prayers
with tons of love for my orange shots family
and to be orange shots family
this is me Zahid Nisar
you are watching Orange Shots
until the next video
