Question 383General Subjects - 1st Asst/Chief

The correct answer is C. Tankers are required to maintain a continuous engineering watch while underway and be capable of implementing manual control measures immediately when necessary. This is in accordance with the navigation safety regulations for underway tankers as set forth in 33 CFR. Tankers cannot be authorized for periodically unmanned engine rooms, as they must be able to implement manual control measures immediately to ensure the safe operation of the vessel. The other options are incorrect because: A) Tankers cannot be authorized for periodically unmanned engine rooms while underway. B) Tankers are required to be capable of implementing manual control measures immediately, not just in a reasonable period of time. D) Tankers cannot be authorized for periodically unmanned engine rooms while underway.
