Leading P&I clubs and industry authorities recommend the adoption of advanced ultrasonic technology for watertightness testing. In their guidelines, they emphasize the reliability, accuracy, and efficiency offered by devices like the Coltraco Portascanner Watertight Plus in ensuring vessel safety and regulatory compliance.

RightShip also endorses, recognizes and supports the use of ultrasonic testing for assessing the weathertightness of hatch covers. In particular, according to their documentation, RightShip recommends that the weather tightness of hatch covers should be checked at least once every 3 months while in case of steel cargo shipment, weather tightness of hatch cover should be carried out by means of ultrasonic testing, before loading and in the presence of the loading surveyor.

In line with these industry best practices, the Coltraco Portascanner® Watertight Plus stands out as a trusted and widely used solution by maritime professionals. Engineered to meet the rigorous demands of the shipping industry, the Portascanner delivers an advanced, user-friendly approach to watertightness testing. Whether for routine inspections or compliance with regulatory audits, it empowers crew members with the tools to conduct fast, accurate, and non-destructive testing—onboard and in real-time.
