Underwater Ultrasonic Thickness Testing

Our Underwater Ultrasonic Thickness Testing (UTT) service provides accurate, non-destructive measurement of steel thickness and structural integrity below the waterline without requiring the vessel to enter dry dock. Performed by qualified underwater inspection specialists, this service helps vessel owners, operators, classification societies, and insurers assess the condition of hull structures while minimizing operational downtime and costs.

Using advanced ultrasonic testing equipment, our divers conduct thickness measurements on hull plating, ballast tanks, sea chests, offshore structures, pipelines, and other submerged steel components. The collected data allows for the identification of corrosion, erosion, wastage, and structural deterioration that may affect the safety and performance of the vessel or marine asset.
