Cargo Operations Quiz

What is the purpose of drying in the general cycle of cargo operations?

• To lower the temperature of the cargo tank before loading

• To remove moisture from cargo tanks and piping system

• To cool or heat the cargo to meet specified temperature

• To reduce oxygen content in the cargo system

What is the main reason for inerting the cargo tanks, piping system, and void spaces?

• To increase the oxygen content for safety

• To reduce the oxygen content to acceptable levels

• To speed up the loading process

• To prevent flammable atmosphere in the subsequent gassing up operations

What is the recommended method for purging the atmosphere within a tank during cargo operations?

• Combustion method

• Dilution method

• Ventilation method

• Displacement method

What is the purpose of gassing up in the cargo operations?

• To reduce inert Gas in the cargo tanks with cargo vapour

• To remove moisture from the cargo tanks

• To reduce oxygen content in the cargo tanks

• To increase the pressure in the cargo tanks

When should pre-cooling be carried out in the cargo operations?

• After loading the cargo

• Before loading the cargo

• During discharge of the cargo

• During the voyage

What is the process of liquid freeing in the cargo operations?

• Draining and stripping the tanks using the stripping pump

• Introducing cold Gas followed by liquid cargo into the tanks

• Purging the inert Gas out of the cargo tanks

• Removing all liquid from the tanks

What should be done before discharging the cargo according to the text?

• Ignore the method of discharging the cargo

• Check the cargo tanks temperatures and pressures

• Skip the pre-operational ship/shore information exchange

• Start the discharge operation immediately

Why is sampling carried out before the commencement of cargo discharge?

• To establish safe conditions before cargo transfer

• To increase the cargo temperature

• To speed up the discharge process

• To reduce the oxygen content in the cargo tanks

What is the purpose of ballasting/de-ballasting in the cargo operations?

• To increase the trim and list of the vessel

• To check the oil content in the ballast water

• To distribute weights to avoid excessive trim, list, or stress

• To speed up the loading process

Why is it important to monitor the cargo temperature during operations?

• To ensure the cargo remains within the specified temperature range

• To increase the cargo pressure

• To speed up the cargo discharge process

• To reduce the inert gas content in the tanks
