Question 3505Deck General70% to pass
While being towed at a 19.5 foot draft, the DEEP DRILLER experiences single amplitude pitching of 7.5 degrees with an 8 second period. You should _______________.
AI Explanation
The correct answer is C) continue towing operations and carefully monitor vessel motions.
This is the correct answer because when a vessel is being towed at a specific draft, the towing operation should continue as long as the vessel motions remain within safe limits. The information provided indicates that the vessel is experiencing a single amplitude pitching of 7.5 degrees with an 8-second period, which is a relatively moderate motion that can be safely monitored during the towing operation. Altering the course or changing the draft may not necessarily improve the motion characteristics and could introduce additional risks or complications.
The other options are incorrect because A) altering the course may not be necessary if the motions are within acceptable limits, B) and D) changing the draft may not be warranted without further assessment of the vessel's stability and motion characteristics at the new draft.
