1
an oil tanker is a ship designed for the bulk transport of oil
2
or its products there are two basic types of oil tankers crude tankers
3
and product tankers crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries.
4
Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets.
5
The size classes range from inland or coastal tankers to the ultra -large crude carriers.
6
In this video, we are focusing on an ultra -large crude tanker.
7
Let's take a closer look at the main parts of this vessel.
8
Pipeline systems are used to load and discharge oil, water, gas, and many other purposes.
9
There is a helicopter landing pad.
10
Cranes are used for transporting heavy equipment on and off the ship.
11
Mast risers are connected to the cargo tanks below.
12
They are designed to release pressure that builds up inside the cargo tanks during the loading or unloading of oil.
13
The accommodation area is where the crew members stay, eat, and sleep.
14
This is the control room.
15
Emergency escape boats are used for the crew members to escape in life -threatening situations.
16
Now let's take a look inside the hull.
17
The oil cargo tanks store crude oil for transportation.
18
Water ballast tanks provide stability for the vessel.
19
In the aft of the vessel, there are heavy fuel oil and marine gas oil tanks that are used to power the ship.
20
a sludge tank stores waste from the treatment system there is
21
also a freshwater tank in between all these tanks of different
22
types of liquid there are empty spaces called the cofferdum and down here is the engine room this is the pump room
23
The crew working on this gigantic vessel can number around 30 people.
24
Not all oil tankers have the exact same design.
25
Many ships might have parts located in different spots, but in this animation, this is the basic design principle.
26
A large crude oil tanker has multiple oil cargo tanks, primarily to avoid free surface effects.
27
Sometimes, the sea can be rough, just like in this scenario.
28
If an oil tanker has only one giant tank to carry oil cargo, it will face free surface effect.
29
When the liquid inside a tank moves from side to side, it generates forces that impact the side of the hull.
30
If the impact to one side of the hull is too strong, it can cause the ship to capsize.
31
To solve this problem, oil tankers have multiple smaller tanks.
32
When the liquid moves, the impact is divided into smaller sections, reducing the impact on one side of the hull.
33
This provides more stability for the vessel.
34
All oil tankers with a length above 120 meters are required to be double hulled.
35
The double hull is designed to protect the oil cargo tanks from external damages.
36
In a single -hulled ship, if the hull is shredded or cracked by any external impacts, it can result in oil leakage into the ocean,
37
endangering marine life, and polluting the environment.
38
The space between the hull and oil cargo tanks are used as water ballast tanks.
39
When not carrying oil, the tank doesn't have enough weight to counter the buoyancy and will easily be moved by the waves.
40
Without stability, it will be difficult for crew members to work and live. To be well stabilized,
41
the bottom part of the vessel needs to be submerged under the water by filling the water ballast tanks. When oil is loaded,
42
the ballast tank will discharge its water back to the sea to Thank you keep the ship from being too heavily loaded.
43
All ships are required to have a water treatment system.
44
It is important because when a ship pumps seawater into the ballast tanks from one location and carries it to another location,
45
it might potentially bring unwanted microorganisms and bacteria.
46
Before discharging water back to the sea in a new location, the water needs to be treated to kill all the harmful bacteria.
47
Copherdom.
48
It is a space which is used to separate different liquid tanks of different types.
49
When two tanks of different liquid types share the same wall, and if there is a crack or leak, two types of liquid will end up spilled out and mixing with each other.
50
That's why with the Copherdom separating two tanks apart, it creates a space for fixing the leak without contaminating the
51
other tank let's take a look at how oil is loaded into the cargo tanks
52
when loading oil weight distribution is very important to consider
53
if weight distribution is uneven it can result in an unwanted accident for example
54
if there is too much weight on one side the vessel
55
will lose its balance to avoid this accident oil has to
56
be loaded evenly each time there is a jungle of pipes here
57
so let's simplify it
58
and focus on the oil loading pipes only this pipeline is used to load
59
and discharge oil in and out of the cargo tank this part is called a manifold
60
and oil enters here a pump is used to push the
61
oil through a bell mouth where the oil comes out into
62
the tanks from the bottom to the top for example in
63
this model there are 15 oil cargo tanks The first pipeline will load oil into these five tanks to ensure
64
that the weight is evenly distributed.
65
The second pipe will load oil into these five tanks, and the third pipe will load oil into the last five tanks.
66
Three sections represented by three different colors for easy view in this animation.
67
In reality, crude oil is black.
68
With this design, it doesn't matter which pipeline is used to load
69
or unload oil first the weight will still be distributed evenly.
70
Oil cargo tanks are also equipped with heating coils to reduce viscosity for easy pumping.
71
Oil tankers use a device called loading arms to load or discharge oil.
72
During offshore oil loading the tanker receives oil directly from the subsea pipeline using a buoy and floating hoses.
73
If an oil tanker is too large to get close to a dock, it will transfer the oil to a smaller tanker to carry it to the dock.

ما هي تقنية التظليل الصوتي؟
التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
