Since 2001, classification societies have collectively recognized ultrasonic testing (UT) as a reliable and approved alternative to traditional hose testing for verifying the weathertight integrity of hatch covers during class and statutory inspections. This method, when performed using calibrated ultrasonic equipment that is type-approved by class societies and operated by qualified personnel, offers a non-invasive, accurate, and repeatable way to assess hatch cover tightness.
To maintain high standards across the maritime industry, the International Association of Classification Societies (IACS) established strict requirements under IACS Unified Requirement (UR) Z17. These criteria ensure that companies performing ultrasonic hatch cover testing:
Use certified and approved ultrasonic devices
Employ trained technicians with a solid grasp of ultrasound theory
Possess practical experience in hatch cover inspection
Understand hatch design, maintenance, and common repair practices
The adoption of ultrasonic testing helps shipowners and operators meet compliance standards while improving inspection efficiency and reducing potential damage to cargo holds caused by water ingress.

White Coral Offshore Services provides professional ultrasonic hatch cover testing using the latest, type-approved devices. Our equipment is regularly calibrated, maintained, and operated by certified ultrasonic technicians to ensure accuracy and compliance with P&I Club, Classification Society, and Flag State requirements.
Each test is delivered with a comprehensive Ultrasonic Hatch Cover Test Report, formatted to meet industry standards and regulatory acceptance criteria.
Key Benefits of Ultrasonic Hatch Cover Testing
Non-destructive and dry testing: No water is used, reducing risk to water-sensitive cargo and avoiding environmental pollution in ports or at sea.
High precision: Detects damaged gaskets, poor compression zones, or leak-prone areas in the hatch sealing system.
Efficient diagnosis: Speeds up leak identification, enabling targeted repairs and reducing unnecessary interventions.
Repair validation: Follow-up testing verifies the success of hatch cover repairs before vessel departure.
No interference with cargo: Testing can be done on loaded or empty holds, allowing flexibility during cargo operations.
Minimal crew involvement: Only basic supervision and safety support from the vessel’s crew are required.
