Underwater pipeline inspection is a critical process used to assess the condition, integrity, and safety of pipelines submerged in bodies of water. These pipelines may transport various substances, including oil, natural gas, water, or other liquids, and they are often found in offshore environments, rivers, lakes, or coastal areas. Conducting regular inspections helps ensure the reliability of these pipelines and prevents environmental incidents.
