What are Underwater NDT & ECT?
Underwater Non-Destructive Testing (NDT) finds defects in structural steel without damaging the part. Eddy Current Testing (ECT) is the underwater go-to for crack detection on welded joints because it works through paint and marine growth — saving the cleaning step that MPI requires. Combined, UT + MPI + ECT + ACFM cover thickness loss, surface cracks, sub-surface flaws and weld integrity on hulls, piles, risers, mooring chains and offshore structures.
When do you need Underwater NDT & ECT?
- Class survey — hull plate UTG for thickness verification
- Post-incident assessment — checking welded joints after impact or grounding
- Asset integrity programme — periodic inspection of jetty piles, risers, mooring chains
- Weld quality check — verifying repair welds before class sign-off
- Crack monitoring — annual inspection of known indications
Our NDT & ECT Process
- Scope definition — joint with client engineer, class surveyor and our Level III certified inspection specialist
- Surface preparation — water-jet cleaning at measurement points (UT/MPI); ECT/ACFM works through coating
- Inspection — diver carries the probe; data streamed live to surface inspector for real-time evaluation
- Recording — full data set captured, photo and video evidence at every point
- Class-format report — measurements, indications, comparison to acceptance criteria, recommendations

Frequently Asked Questions
Q1. UT, MPI or ECT — which do I need?
Ans: UT for thickness loss; MPI for surface cracks on cleaned steel; ECT for crack detection through paint & marine growth (much faster than MPI). We’ll recommend the right method based on what you’re looking for.
Q2. Will the ECT report be accepted by my class society?
Ans: Yes — ECT is accepted by all major class societies for crack detection on welded joints, subject to qualified personnel (which our Level II inspectors are).
Q3. How long does an underwater UT survey take?
Ans: 50 measurement points on a hull: typically 1 dive day. Class-format report delivered within 48 hours.
