Through our exclusive underwater Non-Destructive Testing (NDT) technologies and remote robotic scanners, we empower our customers to perform integrity assessments on their subsea assets including pipelines, flexible/rigid risers, offshore structures and vessels while minimising costs, reducing environmental impact, and enhancing personnel safety.
Subsea NDT Applications
TSC Subsea distinguishes itself by providing a wide array of NDT techniques and subsea robotic inspection systems deployable via remotely operated vehicles (ROVs) or divers. This versatility enables us to carefully choose and utilise the most suitable NDT methods that align with the unique needs of our customers.
We are committed to delivering superior quality and reliable inspection data on time, every time. We assure our customers of accurate subsea asset integrity assessments, enabling them to make well-informed decisions and instilling confidence in their operations.
“With TSC Subsea we found a reliable partner with whom we were able to complete the relevant offshore work in a safe manner, within the scheduled time frame and within the planned budget.”

Subsea Inspection Capabilities
With a track record of over ten years in resolving subsea inspection challenges across various water depths, ranging from the splash zone to ultra-deepwater, we possess the knowledge and experience in assessing the following types of damage mechanisms and typical issues associated with vital underwater assets:
- Validation of In-Line Inspection (ILI) surveys.
- Evaluation of internal pipeline corrosion and erosion.
- Detection and measurement of weld defects.
- Inspection of welds in subsea structures.
- Corrosion Under Insulation (CUI) assessment.
- Measurement of pipeline geometry, including ovality and dents.
- Flange face corrosion inspection.
- Wall thickness measurement for elbow extrados, duplex, and steel.
- Detection and measurement of hydrates.
- Evaluation of grout integrity.
- Identification of flooded annulus in flexible risers.
- Flooded Member Detection (FMD).
- FPSOs hull surveys.
“Each local area data collection was completed 5 times quicker compared with the Computed Tomography (CT) tool used in Gulf of Mexico (GoM) which was the only external local inspection technology available for deepwater production systems at that time.”
