Question 3170 Deck General

The correct answer is D) While on a foreign voyage and outside US jurisdiction, in order to meet manning requirements. This is the correct answer because under US Coast Guard regulations, foreign credentialed personnel may be employed on US-flag towing vessels while operating outside of US jurisdiction, such as on foreign voyages, in order to meet the vessel's manning requirements. This is allowed as long as the foreign credentials are equivalent to the US requirements. The other options are incorrect because US regulations prohibit the employment of foreign credentialed personnel on domestic voyages (option C), and there is no exception that allows their use while operating above the US outer continental shelf (option A). Option B is also incorrect, as the use of foreign credentialed personnel is permitted in certain circumstances as described in option D.
