Question 50 MODU01 - Offshore Installation Manager

The Correct Answer is B A continuous sounding of a fog whistle (or any prolonged sounding device) by a vessel, under both the International Regulations for Preventing Collisions at Sea (COLREGs) and Inland Rules, is designated as a signal of **distress**. This is explicitly listed among the universally recognized distress signals, indicating that the vessel is facing a grave and imminent danger and requires immediate assistance. Here is why the other options are incorrect: * **A) A request that the draw span of a bridge to be opened:** Bridge opening requests are typically signaled using short blasts (usually one prolonged blast followed by one short blast, or simply five short blasts depending on the jurisdiction/local rules, but never a continuous blast). * **C) That the vessel is anchored:** A vessel anchored in fog signals its presence by ringing the bell rapidly for about five seconds at intervals of not more than two minutes, and may follow this with three blasts on the whistle (one short, one prolonged, one short) to give an audible warning to an approaching vessel of her position and the possibility of collision. A continuous blast is not the anchoring signal. * **D) A vessel is broken down and drifting:** While a vessel that is broken down may eventually declare distress (Option B), simply being broken down or drifting in fog has specific maneuvering/warning signals (e.g., the signal for a power-driven vessel underway but stopped and making no way, or the signal for a vessel restricted in her ability to maneuver). A continuous blast is reserved exclusively for the gravest situation: distress.
