Question 2773 Deck General

The correct answer is C) Immediately. The emergency position-indicating radio beacon (EPIRB) should be activated immediately after abandoning a mobile offshore drilling unit (MODU) in an emergency situation. This is because the EPIRB is designed to transmit a distress signal with the vessel's location to search and rescue authorities, allowing them to quickly locate and assist the crew. Activating the EPIRB immediately maximizes the chances of a timely rescue, which is crucial in a life-threatening situation. The other answer choices are incorrect because there is no need to wait for sunset or another vessel to be in sight, and a one-hour delay could significantly reduce the chances of a successful rescue.
