Question 31 MODU01 - Offshore Installation Manager

The Correct Answer is C **Explanation for Option C (Correct):** The illustration D010RR depicts the required daytime shapes prescribed under the International Regulations for Preventing Collisions at Sea (COLREGs) Rule 24 (Towing and Pushing). Specifically, it shows a vessel displaying a **diamond shape**. COLREGs Rule 24(a)(i) requires a vessel engaged in towing, where the length of the tow (measured from the stern of the towing vessel to the after end of the tow) exceeds 200 meters, to exhibit a **diamond shape** where it can best be seen. Therefore, a vessel displaying this shape has a tow that exceeds 200 meters in length. **Explanation of Incorrect Options:** **A) Is at anchor:** A vessel at anchor displays a **ball** shape forward (COLREGs Rule 30). **B) Is not under command:** A vessel not under command displays **two balls** in a vertical line (COLREGs Rule 27(a)). **D) Has a tow that is carrying hazardous cargo:** There is no specific shape required by COLREGs solely for a tow carrying hazardous cargo, although additional shapes (like a cylinder) might be required if the vessel is restricted in its ability to maneuver due to the nature of the operation (e.g., dredging, mine clearance). However, the diamond shape specifically signifies the length of the tow, not the nature of its cargo.
