Question62:-As per MARPOL, for bottom damage, independent calculations for mean outflow shall be done for 0 m and -2.5
m tide conditions. They are combined as follows: *"O_{MB} = 0.7 O_{MB(0)} + 0.3 O_{MB(2.5)}"’. Where: *"O_{MB(0)}"*

= mean outflow for 0 m tide condition; and *"O_{MB(2.5)}"" = mean outflow for -2.5 m tide condition, in *"m*3"". Oil
outflow will be more for "0 m" or " -2.5 m" condition?

A:-0m

8:--2.5 1

C:-(1) and (2)

D:-None of the above

Correct Answer:- Option-B
Question63:-A double hull bulk carrier has 7 cargo holds. The vessel's beam is 42.0 m. The width of each side wing tank is
2.5 m. There is no centerline bulkhead in the cargo hold. The probability of side damage occurring between the transverse
bulkheads bounding no. 2 space is 0.1266. The following will hold true:

A:-Insufficient information

B:-Damage probability (cargo hold) > 0.1266
Damage probability (cargo hold) = Damage probability (wing tank)

C:-(2) and (4)

D:-Damage probability (cargo hold) < 0.1266
Damage probability (cargo hold) > Damage probability (wing tank)
