Question 3782 Deck General

The correct answer is A) If it creates a hazard to navigation. According to Coast Guard regulations, the master or person in charge of a mobile offshore drilling unit (MODU) is required to submit a casualty report for an intentional grounding if it creates a hazard to navigation. This is because an intentional grounding that poses a risk to other vessels or impedes the flow of maritime traffic needs to be reported to the Coast Guard for proper response and mitigation. The other options are incorrect because: B) Submitting a casualty report is not at the owner's discretion, but a regulatory requirement; C) The duration of the grounding does not determine the reporting requirement; and D) A casualty report is not required under all conditions, only if the grounding creates a navigational hazard.
