AAn internal inspection of the non-metallic expansion joint is performed every 5 years regardless of the frequency of periodic vessel inspections.
BAn internal inspection of the non-metallic expansion joint is performed every 2.5 years regardless of the frequency of periodic vessel inspections.
CAn internal inspection of the non-metallic expansion joint is performed at every periodic ship inspection.
DAn internal inspection of the non-metallic expansion joint is performed whenever an external inspection reveals excessive wear or other signs of deterioration or damage.
AI Explanation

The correct answer is D) An internal inspection of the non-metallic expansion joint is performed whenever an external inspection reveals excessive wear or other signs of deterioration or damage. This is the correct answer because the 46 CFR regulations state that internal inspections of non-metallic expansion joints are only required when the external inspection indicates potential issues, rather than at a fixed interval. The regulations do not mandate internal inspections at regular intervals, but rather tie them to the condition of the expansion joint as observed during the external inspection. The other options are incorrect because they prescribe internal inspections at fixed intervals, which is not the requirement according to the 46 CFR regulations pertaining to piping systems and periodic tests and inspections.
