During a submarine inspection, at what maximum interval do divers pass over each pipe?

In submarine inspections, divers are tasked with closely monitoring the integrity of underwater pipelines. The standard practice of passing over each pipe at a maximum interval of 20 feet is based on ensuring detailed observation and minimizing the risk of missing critical defects or issues that could affect the pipeline's safety and operational effectiveness.

This distance allows divers to maintain a thorough inspection process while also considering the visibility and assessment of various potential hazards or anomalies. Smaller intervals could lead to increased time and resource expenditures, while larger intervals may risk overlooking significant problems.

As a result, the 20-foot interval strikes a balance, allowing for effective surveillance while safeguarding the structural and operational integrity of pipelines in underwater environments.
