On aluminium hulls we measure residual thickness and evaluate typical damage patterns such as pitting and galvanic corrosion. Methodically similar to steel measurement but requires adapted sound velocities, transducers and an understanding of typical aluminium corrosion.
Aluminium hulls behave acoustically differently from steel: different sound velocity, different typical thicknesses (often 6–12 mm), different corrosion patterns. A plain "standard" steel-style measurement returns distorted values without adaptation.
We calibrate the device on board material or reference blocks before each session, select the appropriate transducer and interpret readings against typical aluminium corrosion patterns.
Typical priorities:
As with steel we work in a defined grid and take multiple readings per point. You receive a report with grid plan, values, statistics and assessment. Where galvanic issues are suspected we review anode concept, bonding and electrical layout in passing, without independently rebuilding them.
For mixed constructions or refits we combine the aluminium measurement with steel hull measurement and — if relevant — carbon ultrasonic testing.
Vessel type, year, mooring and reason — you will receive scope and fee.
