For means of abandonment of a MODU, which type of embarkation does not require prior approval by the Coast Guard?

Correct Answer: Option D — Fixed ladders

Fixed ladders are considered permanent structural features of a MODU and do not require specific Coast Guard approval for use as a means of abandonment. Conversely, movable equipment like safety booms or elevators requires rigorous testing and certification to ensure they function reliably during emergency evacuation scenarios.
