Question 3874 Deck General

The correct answer is A) engages in a voyage to a port of another country which is a party of MARPOL. Under the regulations implementing MARPOL (the International Convention for the Prevention of Pollution from Ships), a mobile offshore drilling unit is required to have an International Oil Pollution Prevention (IOPP) Certificate when it engages in a voyage to a port of another country that is a party to MARPOL. This is because MARPOL requires ships, including mobile offshore drilling units, to have a valid IOPP Certificate when entering the port of another MARPOL country. The other answer choices are incorrect because they do not align with the MARPOL regulations. Moving to a new drilling location in U.S. waters or drilling on the Outer Continental Shelf do not, on their own, trigger the requirement for an IOPP Certificate under MARPOL.
