A navigable waterway inspection includes which of the following elements?

The choice that correctly identifies the elements of a navigable waterway inspection includes aspects that are essential for ensuring the integrity and safety of pipelines that may interact with or be located near water.

Pipeline location is fundamental as it determines where potential risks may emerge and informs the operational practices that need to be put in place for safety and compliance purposes in navigable waters. Surface inspection involves the evaluation of the visible aspects of the pipeline system, including checking for signs of leaks or damage that could adversely affect the waterway.

Submarine inspection, which often involves underwater assessments of pipelines, is crucial in navigable waterway inspections since pipelines may be submerged. This type of inspection ensures that any issues below the water's surface, such as deterioration or structural integrity problems, are addressed properly. These three components collectively ensure comprehensive monitoring and management of waterway conditions related to pipeline operations, helping to prevent accidents and protect environmental quality.

The other options include some relevant elements but either mix inspections that are not specifically exclusive to navigable waterways or incorporate checks and analyses that would not necessarily be part of a standard navigable waterway inspection. For example, diving equipment checks and water quality testing, while important in other contexts, do not capture the primary focus of a navigable water
