Question 49 MODU01 - Offshore Installation Manager

The Correct Answer is C **Why option C ("The vessel is in distress") is correct:** According to both the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Annex IV (Distress Signals), and corresponding Inland navigation rules, the firing of a rocket or shell, or other explosive signal, fired at intervals of about one minute, is explicitly listed as an internationally recognized signal indicating that a vessel is in **distress** and requires assistance. **Why the other options are incorrect:** * **A) The gun is being used to sound passing signals:** Passing signals (like those used when meeting, crossing, or overtaking) are short blasts sounded by the vessel's whistle or horn. Firing a gun at one-minute intervals is a distress signal, not a standard maneuver signal. * **B) All vessels are to clear the area:** While other vessels must respond to a distress signal, the primary meaning of the signal is that the signaling vessel requires immediate aid. The signal does not function as a command for others to clear out. * **D) All is clear and it is safe to pass:** This signal indicates the exact opposite. A vessel firing a gun at one-minute intervals is in a life-threatening situation and requires immediate attention and assistance; it does not indicate clear conditions or safety.
