Cargo Handling. Containment. Test 2

On what type of gas carrier do we use spherical cargo tanks?

Spherical cargo tanks are used on fully pressurised gas carriers
Spherical cargo tanks are used only on semi-refrigerated gas carriers
Spherical cargo tanks are not allowed on gas carriers
Spherical cargo tanks are used on all types of gas carrier, fully refrigerated, semi-refrigerated and fully pressurised gas carriers

Is there any requirement to the atmosphere in the hold space when carrying flamable cargo?

There is no requirements for the hold space, but we must have a neutral atmosphere in the cargo tank
Yes, dry atmosphere in hold space on all gas carriers exempt from those who have independent type C tanks
Yes, cargo vapour in hold space on all gas carriers
Yes, neutral atmosphere in hold space on all gas carriers exempt from those who have independent type C tanks

Explain the difference between absolute pressure and manometer pressure.

Absolute pressure is atmospheric pressure minus manometer pressure, to be used in technical tables
Absolute pressure is equal to manometer pressure and must be used in technical tables
Absolute pressure is atmospheric pressure added with manometer pressure, to be used in technical tables
Absolute pressure is atmospheric pressure multiplied with manometer pressure, to be used in technical tables

Are all independent tanks self-supported?

Do we find integral tanks as cargo tanks on gas carriers?

Integral tanks are allowed on all types of gas carriers
Integral tanks are normally not allowed on gas carriers other than LPG carriers
Integral tanks are normally not allowed on gas carriers if the cargo to be carryed have boiling point less than
Integral tanks are normally allowed on gas carriers if the cargo to be carryed have temperature above

What is the design temperature on the cargo containment system on a LPG/LEG carrier?

Why do we insulate the cargo containment?

What sort of information must an inhibitor certificate contain?

Inhibitor name, concentration of inhibitor, duration of effectiveness of inhibitor, expected duration of sea voyage, temperature limitation qualifying the lifetime of the inhibitor and number of cargo tanks inhibited
Inhibitor name, number of cargo tanks inhibited, duration of effectiveness of inhibitor, expected duration of sea voyage and temperature limitation qualifying the lifetime of the inhibitor
Inhibitor name, number of cargo tanks inhibited, duration of effectiveness of inhibitor, expected duration of sea voyage and date the cargo tanks are inhibited
Inhibitor name, date inhibited and expire date of the inhibitor
