MARPOL Annex II Quiz

For Category X substances, what happens if prewashing is not carried out?

• The ship will be fined

• Discharge is permitted without prewash

• The residue must be retained and sent to shore reception facilities

• The ship must slow down for safer discharge

According to MARPOL Annex II, Category Z substances are subject to:

• Stricter dilution and quantity controls compared to Category Y

• More lenient dilution and discharge quantity restrictions than Category Y

• Identical rules to Category X

• Prohibited discharge without prewash

In special areas such as the Antarctic, the discharge of Category Y substances is:

• Strictly prohibited or subject to more stringent requirements

• Permitted with limited dilution

• Allowed only at depths greater than 50 meters

• Unregulated

Prewash procedures for tanks carrying Category X substances must follow guidelines specified in:

• The ship's ballast water management plan

• The Procedures and Arrangements Manual

• The ECDIS system regulations

• The MARPOL Annex I manual

Which of the following accurately describes the discharge of Category Y substances?

• Only allowed if tanks are not cleaned

• Prohibited in international waters

• Permitted if the discharge occurs at least 12 nautical miles from land

• Allowed in enclosed spaces

If a ship constructed before 1 January 2007 is discharging Category Z residues, what condition applies?

• Discharge must be below the waterline

• Above-water discharge is allowed

• The ship must travel at a speed of at least 10 knots

• Discharge is prohibited

What minimum speed is required for ships discharging Category Y residues en route?

• 5 knots

• 4 knots for self-propelled ships

• 7 knots for self-propelled ships

• 10 knots for all ships

What is the primary objective of Regulation 13 (Prewash and Tank Cleaning) under MARPOL Annex II?

• To minimize pollution from tank cleaning residues

• To allow discharge at reduced speeds

• To ensure safety procedures during loading

• To reduce ship speed before discharge

According to MARPOL Annex II, the discharge of Category Z substances is regulated by:

• Mandatory prewash procedures

• Strict adherence to specific discharge rates

• Prohibition in all territorial waters

• More lenient discharge standards than Category X

The discharge of Category X residues must occur at:

• 25 meters depth or more

• 50 meters from the ship's hull

• In shore reception facilities after prewash

• In compliance with Annex III standards
