Which MARPOL regulation addresses any failure of oil filtering equipment?

• A. MARPOL I/17.5
• B. MARPOL I/17.3
• C. MARPOL I/17.2
• D. MARPOL I/7.1

Answer: (A)

Regulation 17 of MARPOL Annex I deals with oil filtering equipment and how oily-water mixtures are processed and discharged. Within this regulation, the provision that directly addresses what to do if the oil filtering equipment fails is the one that lays out actions to take when a fault occurs. It specifies that any failure of the oil filtering equipment must be handled promptly, with proper procedures followed to prevent improper discharges, and that the incident must be recorded and acted upon (including maintenance or repair and notifying the master). This makes it the right choice because it directly covers handling faults in the equipment itself, which is exactly what the question asks about.

The other numbers refer to different aspects of the oil filtering system or MARPOL rules in general, such as design, testing, or other discharge requirements, rather than the process for dealing with a failure of the equipment.
