Question 3858 Deck General

The correct answer is B) Shut down the transfer operation. The reasoning for this is that in the event of a safety or pollution hazard during fuel transfer operations on a mobile offshore drilling unit (MODU), the first and most critical action is to immediately shut down the transfer operation. This is in accordance with regulations and best practices for preventing an incident from escalating or causing further harm. Sounding the fire alarm (A) or notifying the ballast control operator (C) should be secondary actions after the transfer has been stopped. Waiting for the person in charge to act (D) could result in valuable time being lost and the hazardous situation potentially worsening.
