This is a video detailing the International shore connection, its care, parts and use in any eventuality.
The dimensions, as well as connection are explained for your understanding.
I hope this video will help you in your future career paths ❤️
Good afternoon, so today we will discuss about international shore connection. So this is an
international shore connection box and these are the details we will discuss all of this in detail.
So let us start watching the video. So the international shore connection is basically
used to get a common link between the shore hydrant and the ship's firemen. Remember
different types of ship will have different type of fire hydrant.
So that fire hydrants type and size cannot be standardized but the shore connection you can
standardize it. So what the international shore connection is going to do is it's going to have
one side of the flange with international standards and that going that side can be
connected to the shore hydrant side and the other side is going to be of your ship's specific
hydrant. So this hydrant you can directly either connect it connect to your ship's
fire hydrant because all couplings are going to be male and female. So you can either connect
it directly to your ship or you can rig a fire hose from the international shore connection
and connect it to your ship's hydrant. So this is the basically the reason why
international shore connection is given. So at least if you have one hose to charge your fire
main you can fight fire somewhere else on your ship because you can isolate your fire main and
at one point if you put the water at least from the other side the fire main will get charged and
from the other side you can fight the fire using your ship's fire hose.
Now there are locations that are to be specific for international shore connection where it is
going to be kept is basically as per your ship's fire control and safety plan. So you should always
make sure that your international shore connection is as per your ship's fire control and safety plan
and mostly it is in a place that is going to be accessible by the fire brigade. Now the dimensions
I will show it to you along with the explanation then it is going to be a better understanding.
So this is our international shore connection. It will be kept inside a box and this symbol is
the IMO symbol for international shore connection. So once I open the box we will be able to see the
international shore connection. I have kept all these dimensions here so that you can read it as
you watch the video. So the international shore connection I am taking out from the box.
This is the international shore connection and the associated rubber packing you can see this.
Now these have some certain dimensions. See this is practically your ship's
hydrant. So this dimension will be in accordance with your ship. Now the standards are for this
place. This is the outer diameter. This the outer diameter should be 178 mm and the inner diameter
should be 64 mm. Now the bolt circle diameter. This is the bolt circle. This diameter should be
132 mm. Now this bolt they will be having four slots. All these slots should have a
diameter of minimum 19 mm and the flange thickness. This is the flange thickness. The
flange thickness should be at least 14.5 mm. Now there are requirements for bolts and nuts. The
bolts and nuts should be four in number and should have a length of minimum 50 millimeter
and a dia of 16 mm. So these are the bolts and nuts. I am replacing it. So these are the bolts
and nuts. It looks a little bit dirty but this is basically grease applied so that it can be
easily used in case of an emergency and washers should be eight in number. So each of the bolt
and nut should include two washers each. So these are the two washers. So these are the requirements
and we have certain extra washers inside just for the case of emergency. Now let us go and
try out our international shore connection. I will show you how it can be used. Before trying
out the international shore connection let me show you something else that is important. This
is the ship's fire and safety plan. In the ship's fire and safety plan the number and the location
of the international shore connection is given. You can see the international shore connection,
the number and on top is the place where that has to be kept. Now let us try out the international
shore connection. Now this is the international shore connection with one side as per our ship
specific hydrant and the other side is the flange. So we will open our ship's hydrant cap and as you
can see the ship side of the international shore connection will align perfectly with our hydrant.
So let me rig it in. Now after I rigged it in I'll turn it and lock it. Now the shore side will be
having a hose and their hose will have at one side the same specific as our international shore
connection. So that will become a perfect fit and the four slots you can put the bolts and tight it.
Then when the water is pumped in and our hydrant is opened what is going to happen is we are going
to pressurize our ship's fire main. Suppose the international shore connection of the port is
fixed on the land how we are going to use it is we will use a fire hose and we will connect the
fire hose to our fire hydrant and at the other end of the fire hose we will connect to the
international shore connection. Now this side can be taken out to the land and connected
to the flange of the port. So once the water is pumped in and our hydrant cap is open
again our fire main is going to be charged. I hope you got a good understanding. Thank you.
