Question 134Steam Plants - 1st Asst/Chief

The correct answer is D. According to U.S. Coast Guard regulations, if the maximum steam generating capacity of a boiler is increased, the vessel must be re-inspected and the captain's license must be endorsed to reflect the increased capacity. This is because the increased steam generation capacity represents a significant change to the vessel's equipment and systems, which must be evaluated for safety and compliance purposes. The other answer choices are incorrect because they do not accurately reflect the Coast Guard's regulatory requirements in this scenario.
