InDepth Diving provides advanced Non-Destructive Testing (NDT) services for underwater structures across a wide range of marine, civil, and industrial environments. Our inspection team includes certified CSWIP 3.1 and 3.2 Underwater Inspectors, ensuring that all work is carried out to internationally recognised standards with the highest level of technical accuracy and professional integrity.
We conduct comprehensive underwater inspections and testing to assess the condition, safety, and compliance of submerged assets such as bridge piers, pipelines, piles, moorings, tanks, offshore platforms, and ship hulls. Our team is experienced in both routine maintenance inspections and critical assessments following structural incidents or extreme weather events.
Each inspection is supported by detailed technical reports, including photographic evidence, data analysis, and actionable recommendations. Reports are formatted to suit client requirements and can be integrated into broader asset management or compliance systems.
At InDepth Diving, our CSWIP-qualified divers are backed by surface support teams and project managers who ensure all inspections are conducted safely, efficiently, and in full compliance with AS/NZS 2299 and other relevant international standards. Whether as part of a planned maintenance program or a time-sensitive investigation, our underwater NDT services help clients make informed decisions, reduce risk, and extend the lifespan of critical infrastructure.
InDepth Diving provides advanced inspection and condition assessment services both above and below the waterline, delivering accurate, data-driven insights that support asset management, maintenance planning, and regulatory compliance. Our services include conventional visual inspections, high-resolution 3D scanning, and a range of non-destructive testing (NDT) techniques, all conducted by qualified professionals in accordance with industry best practices and standards, Eddy current and MPI.
Visual Inspections
We offer detailed visual inspections carried out by certified divers and technicians using high-definition video and photography equipment. These inspections provide clients with a clear understanding of the condition of underwater and above-water structures, including signs of wear, corrosion, impact damage, or marine growth. Real-time surface monitoring and recorded footage allow for client oversight and post-inspection analysis.
3D Scanning
For projects requiring a higher level of precision, InDepth Diving employs 3D scanning technology, to create accurate digital models of underwater structures and terrain. This method is ideal for:
Our 3D scans allow clients and engineers to interact with and analyse underwater environments virtually, improving planning, reducing risk, and enhancing documentation accuracy.
