Frequently asked questions about our diving services for utility companies
How often should utility companies schedule underwater inspections?
The frequency of underwater inspections depends on various factors, including the type of infrastructure, environmental conditions, regulatory requirements, and performance data.
Water treatment facilities require regular inspections due to changing water conditions, sedimentation, and potential issues with infrastructure integrity. Inspections may be scheduled annually or semi-annually, with more frequent assessments in regions prone to environmental changes or extreme weather events.
The frequency of inspections for pipelines varies based on factors such as material, age, and location. In some cases, inspections may be conducted every 1-5 years, with more frequent assessments for critical or high-risk segments. Regular inspections help identify corrosion, damage, or other issues that could affect the reliability of these assets.
Underwater inspections for oil and gas installations, including platforms and subsea pipelines, are crucial for ensuring the safety and integrity of the infrastructure. Inspections are usually annual or as per regulatory requirements, with more frequent assessments during major maintenance or in response to specific events, such as storms or seismic activity.
