Structural Inspection

Sonomatic has a strong track record of inspection and related integrity activity in support of Structural Integrity Management. Our work in this area has tended to focus on safety and business-critical applications. The aim is to provide clients with accurate and reliable information on which to base their integrity plans and decisions.

Subsea structures can be subject to a variety of integrity threats both internal and external. Subsea structures require a variety of options in terms of deployment and access solutions.

Sonomatic is well suited with a wide range of inspection techniques to provide the best solution for the integrity threat present. Furthermore, Sonomatic has a wide range of existing ROV and Diver solutions that can meet most access requirements. When a custom access solution is required, Sonomatic has a depth of experience delivering from initial concept to field execution on custom solutions for structural inspection requirements.

Subsea Structural Inspection Applications

Corrosion Inspections and Mapping
  • Corrosion can be a serious problem for any project, with it being capable of causing serious damage to various structures on a project even during the building phase. Our inspection techniques are capable of detecting and mapping areas that are corroded before they become major problems.
Crack Detection
  • A crack in the structure of any project can mean potential disaster both from a monetary and personal standpoint. The numerous techniques Sonomatic can deploy are able to find and identify bot internal and external cracks while staying in accordance with appropriate health and safety regulations.

Cleaning & Corrosion Mapping Inspection of Large Subsea Oil Storage Tank

Sonomatic adapted existing subsea inspection equipment (MAG-Rover), to enable simultaneous water jet cleaning and ultrasonic PA data collection on a subsea structure. A new challenge for Sonomatic with an intense development process due to vessel operational timeframes. We completed the task in hand, successfully with all stakeholders very satisfied with the outcome.
