Underwater NDT Inspections
Harcan Marine offers comprehensive underwater NDT (non-destructive testing) services designed to assess the condition of underwater structures and materials.
With 30+ years of experience and a team of certified professionals, we provide accurate and reliable testing solutions that help identify potential issues before they become costly problems.
Whether dealing with submerged steel piles, subsea pipelines, or ferry terminals, our underwater NDT services give you the insights you need to maintain safety and extend the life of your infrastructure.
What Is Underwater NDT?
Underwater NDT, or underwater non-destructive testing, evaluates the integrity of underwater structures without causing damage. This method is vital for inspecting materials like steel, concrete, and composites exposed to harsh underwater environments. It allows for accurate structural health assessments, ensuring that maintenance or repairs only occur when necessary.
Harcan Marine offers various underwater dive services, including underwater NDT inspections, using advanced techniques for the highest quality results. Our expert divers, trained in CSWIP 3.1 & 3.2 certifications, use specialised equipment to provide detailed information about the condition of your underwater assets.

How Underwater NDT Inspections Solve Your Structural Problems
Prevent Costly Repairs
Underwater NDT inspections help detect issues early so you can address minor damage before it escalates into major, costly repairs. Regular inspections help identify the need for underwater welding, underwater concreting, or other remedial actions to preserve the structural integrity of your assets.
Improve Safety and Compliance
Maintaining safe and compliant structures is essential for operational and regulatory purposes. With our underwater NDT inspections, you’ll receive detailed reports, allowing you to make informed decisions about repairs, maintenance, and asset management. This proactive approach helps avoid costly fines or accidents caused by structural failures.
Extend Asset Lifespan
Regular underwater NDT inspections help extend the life of underwater assets like subsea pipelines, pontoons, and steel piles. By identifying areas that need reinforcement or repair, you can optimise the lifespan of your infrastructure, ensuring it remains operational for years to come.
Our Underwater NDT Inspection Services
Harcan Marine offers a variety of underwater NDT inspections, including:
-
Ultrasonic Wall Thickness Inspection
This method measures the thickness of materials to detect corrosion, erosion, or any damage that may compromise structural integrity. -
Magnetic Particle Inspection
Used for detecting surface and near-surface flaws in ferromagnetic materials, this method is ideal for underwater welding inspections and repairs. -
Dye Penetrant Inspection
A non-invasive method that highlights cracks and surface defects by applying a visible dye to the material being inspected. -
Eddy Current Inspection (ECI)
This technique uses electromagnetic induction to detect flaws in conductive materials, making it ideal for inspecting metal structures like steel piles and pipelines. -
Visual & Dimensional Inspection
We visually inspect underwater structures using trained divers and advanced equipment to identify damage and ensure correct dimensions and alignment. -
Laser Scanning/Mapping
Laser technology allows us to create accurate 3D models of underwater structures, providing detailed data for further analysis. -
Cathodic Protection & Anode Potential Testing
These tests assess the effectiveness of corrosion protection systems in underwater structures, ensuring they remain safe and operational.

What is the difference between underwater NDT and regular NDT?Underwater NDT inspections are specifically designed to assess structures submerged in water, such as subsea pipelines, pontoons, and steel piles. The key difference is that underwater inspections must account for the challenges of working in an aquatic environment, such as visibility, currents, and pressure. Regular NDT, on the other hand, is typically used for inspections above water.
-
How do I know if my underwater structure needs an underwater magnetic particle inspection?If your structure is exposed to harsh underwater conditions or has been in service for a long time, it’s a good idea to schedule regular NDT inspections. Early detection of wear, corrosion, or other issues can prevent costly damage and ensure the safety of your infrastructure.
-
What types of damage can underwater non-destructive testing detect?Underwater NDT can detect multiple issues, including corrosion, cracks, material thinning, and structural misalignment. These inspections help identify potential problems before they lead to significant damage or failure, ensuring your structure remains safe and operational.
-
How often should I schedule underwater NDT inspections?The frequency of underwater NDT inspections depends on the type of structure and environmental factors. Typically, inspections are scheduled annually or biannually. However, more frequent inspections may be recommended for high-risk areas or critical infrastructure.
