Offshore oil platforms are fixed or floating structures. It used for oil and gas exploration, production and processing in the ocean. They are usually built far from the coastline to exploit oil and gas resources on the seabed. Offshore platforms are designed and built to cope with extreme conditions in the marine environment, such as storms, waves, corrosion, and changes in seabed geology.

Offshore oil platforms and ships are in a harsh marine environment and face multiple risks such as extreme weather, salt spray corrosion, mechanical wear, and structural aging for a long time. Therefore, regular and accurate non-destructive testing (NDT) of their structures is crucial. These detection methods help ensure the safe operation of platforms and ships, prevent catastrophic failures, ensure the safety of personnel, and reduce maintenance costs.

First: The importance of NDT inspection camera in Offshore Oil Platforms and Ships

• Corrosion and wear monitoring: Saltwater and humid air can cause corrosion and degradation of metal structures (such as steel). So regular non-destructive testing helps identify potential corrosion, cracks or other damage.
• Structural integrity assessment: Structural safety is critical in the design and operation of offshore platforms and ships. Non-destructive testing can accurately assess the strength of supporting structures, pipelines and shells to ensure their load-bearing capacity and durability.
• Reduce downtime: By identifying potential defects in advance, non-destructive testing can avoid emergency repairs and downtime, thereby reducing the impact on production or transportation.
