1. Description of camber, sheer, tumble home, Rise
of floor by sketch?
Camber:-The
transverse curvature of the deck from the centerline down to the sides. This
camber is used on exposed deck to drive water to the sides of the ship.
Sheer:- The
curvature of the deck in a fore & aft directions, rising from midship to
the maximum at the ends. It makes a ship more seaworthy by raising the deck at
the fore & after ends further from the water and by reducing the volume of
water coming on the deck.
Tumble
Home:- In some ships, the midship side shell in the region of the upper deck is
curved slightly towards the centre line, thus reducing the width of the upper
deck & decks above.
Rise of
Floor:- The bottom shell of ship is sometimes sloped up from the keel to
the bilge to facilitate drainage. The rise of floor is very small.
2. What is freeboard and reserve buoyancy ?
Freeboard:-It
is the distance from the waterline to the top of the deck plating at the side
of the deck amidships.
Reserve
Buoyancy:- It is the potential buoyancy of a ship and depends upon the intact,
watertight volume above the waterline.
When a mass
is added to ship, or buoyancy is lost due to bilging, the reserve buoyancy is
converted into buoyancy by increasing the draught. If the loss in bupyancy
exceeds the reserve buoyancy the V/L will sink.
3. why tankers have less freeboard
The
openings in the tankers are small than of other ship & also the
permeability is more.
4. what do u mean by stability of ship. How a stable
ship returns to upright posn if heeled by external force.
STABILITY
OF SHIP: The tendency of ship to come back to its upright position when healed
by external force is defined as the stability of the ship.
When a ship
is healed the centre of buoyancy shifts, this forms a righting lever . thus the
wt. of the ship
5. what is tender and stiff ship.
Tender
Ship:- The ship with a small Metacentric height has a small righting lever
at any angle & will roll easily is said to be tender ship. In tender ship,
In it the centre of gravity lies below the transverse metacentre. The GM is
more than GZ. & these kind of ship are more stable.
Stiff
Ship:- The ship
with a large Metacentric height has a large righting lever at any angle &
has considerable resistance to rolling. A stiff ship is very uncomfortable. In
it the Centre of Gravity lies above the transverse metacentre.
6. What is free surface effect. How knowledge of free surface effect will
be useful. How it is reduced constructionally.
Free
Surface Effect:- When a tank of liquid is partially filled &
the mass of liquid is moved. This movement affects the Metacentric height. This
is called free surface effect.
If free
surface effects becomes more, then ship may Capsize.
7.Collision bulkhead purpose and location.
Purpose:-
·
Avoids
flooding of ship in case of damage to bows.
Location
·
Location is
such that it is not so much forward as to get damaged on impact , Neither
it should be too far aft so that compartment flooded forward causes
extensive trim by head. As a rule located at minimum distance to get
maximum space for cargo.
·
Minimum
at 1/20 of ships length from forward perpendicular
·
The
collision bulkhead is continuous to upper most continuous deck
·
The
collision bulkhead is 20% stronger than other bulkheads
·
Collision
bulkhead is 5 to 8 percent of ships length from forward.

a damage.
Various
Methods of Reducing Rolling are:-
a.
Fin stabliser
b. Bilge
keel
10.

It is half
of the length of the ship. Starting from midship to fore & aft equally
distanced.
11.
Mid ship section of bulk carrier and tanker.
12.
What is margin line.
Margin
Line:- It is the imaginary line which is drawn 75mm below the
uppermost continuous deck. It Denotes the limit, upto which can be flooded/
loaded without sinking.
13.
What is angle of loll?
Angle of
LOL:- It is the angle at which the ship with initial negative
Metacentric height will lie at rest in still water.
If the ship
is further inclined to an angle less than angle of loll, the ship will
sink.
14.
what are GZ and KN curves.
15.
sketch plimsol marking.
16.
How aft peak tank is sealed from stern tube.
The
propeller enters the shaft outside from the ship, acting as its barrier. In
case of water cooled Stern Tube, Gland packing are used to prevent water
ingress inside. But incase of Lignum vitae bearing, some water is allowed to
go.
In case of
Oil cooled Stern tube, the rubber seals fitted with springs are used.
17.
what is block coefficient. If we say that block coefficient of one ship is 0.9
and 0ther 0.95. what does it mean.
Block
Coefficient:- It is the ratio of volume of displacement to the product of
the length, breadth & draught.
Cb = Volume of displacement / (L x B x d)
When Block
coef. If more, it means Volume of displacement is more.

Sprinkler system how tested?
Testing
procedure
a. Close the section isolating valve, this will raise an alarm indicating zone
isolation.
b. Now, open the test valve, if no water comes out, then it means the NR valve
placed after the section isolating valve is not leaking.
c. Since, the section after the NR valve remains pressurized, opening of the
drain valve will cause the water pressure in the section line to decrease. A
pressure switch sensor senses the decreased pressure & raises an alarm.
d. Now, close the drain valve, open the section isolating stop valve. To check
the flow switch, open the flow test switch to activate an alarm.
e. All the above alarms will be indicated on the navigation bridge, E/room as
well as in the Fire Control Room. The alarm will also indicate the particular
zone from where it has risen.
f. If all the alarm conditions are satisfied, close all the testing valves,
open the section isolating valve, purge the sprinkler line by air and again
keep the line pressurized. Check from the pressure gauge, that proper pressure
has been maintained or not.

76.Meaning
of Panting,Pounding?
Panting :- As the
waves pass along the ship they cause fluctuations in water pressure which tend
to create an in- and- out movement of the shell plating. The
effect is mostly found to be greatest at the ends of the ship, particularly at
the fore end. Such effect is termed as Panting.
Pounding:-
When a ship meets heavy weather and commences heaving and pitcxhing, the rise
of the fore end of the ship occasionally synchronises with the trough of the
wave. The fore end then emerges from the water and re-enters with a tremendous
slamming effect known as pounding.

COW :- Crude Oil Washing
As per
MARPOL Annex 1, Regulation 33. Regulation for the prevention of pollution by
oil .Every crude oil tanker of 20000 Dwt and above shall be fitted with cargo
tank cleaning system using crude oil washing.
The purpose
of COW is to reduce accumulation of sludge in tanks & reduce the amount of
carry over cargo.
During
operation of COW, tanks must have oxygen content less than 8 % and under
positive IG Pressure.
The
advantage of COW is that tank remains clean & ROB cargo is less & hence
increases cargo carrying capacity.
79. What IG
System Requirement. Why IG System not used on ships which are less than 20000
dwt?
Every oil tanker of 20000 DWT or above should be provided with an IG System.
IG System
is not used on ship which are less than 20000Dwt because COW is not applicable
to ship which are lesser than 20000 DWT .
