Accepted Answer

Sulfur oxide (SOx) and nitrogen oxide (NOx) emissions from ship exhausts

Answer

ECAs under MARPOL Annex VI require ships to use low-sulfur fuel or exhaust cleaning systems to reduce SOx and NOx air emissions in designated coastal areas.

Question 2

What does 'graywater' refer to on a cruise ship?

Accepted Answer

Wastewater from sinks, showers, laundry, and galleys (excluding toilet waste)

Answer

Graywater is wastewater from cabin sinks, showers, laundries, and galleys that is less contaminated than sewage (blackwater) but still regulated.

Accepted Answer

12 nautical miles

MARPOL Annex IV prohibits discharge of untreated sewage within 12 nautical miles of the nearest land, requiring advanced treatment before nearshore discharge.

Question 4

What is an 'Exhaust Gas Cleaning System (scrubber)' used for on a cruise ship?

Accepted Answer

Removing sulfur from exhaust gases to comply with low-sulfur emission regulations

Answer

Exhaust gas scrubbers wash sulfur from engine exhaust gases, allowing ships to burn cheaper high-sulfur fuel while still meeting MARPOL emission limits.
