In 2001, classification societies collectively agreed that ultrasonic testing, conducted with equipment approved by class and operated by qualified professionals, was deemed an acceptable alternative to hose testing. This method serves to determine the weathertight integrity of hatch covers during class and statutory inspections. To establish standards for firms engaged in ultrasonic testing, IACS developed criteria under IACS UR Z17. This measure aimed to ensure that surveyors involved in checking hatch covers possessed a comprehensive understanding of ultrasound theory, practical testing experience, and a foundational knowledge of hatch-cover design, maintenance, and repairs. The use of calibrated and classification society type-approved equipment is essential to guarantee the repeatability of test results.
More about Ultrasonic Hatch Cover Testing
We utilize the latest model of Ultrasonic hatch cover testing devices, consistently calibrated, and maintained in readiness for operation. These devices are operated exclusively by certified Ultrasonic equipment operators. Our service includes the provision of a standard Ultrasonic Hatch Cover Test Report, formatted to meet the acceptance criteria of P&I clubs, Classification Societies, and Flag States.
The utilization of ultrasonic testing equipment offers several advantages:
- Ultrasonic testing is a reliable and non-destructive method, providing insights into the compression status of the sealing system.
- It facilitates precise detection of damaged or poorly compressed areas, significantly reducing the time required for identifying potential leaks.
- Once the leak location is identified, the appropriate repair method can be determined, allowing for targeted repairs and avoiding unnecessary extensive interventions. Subsequent tests can validate the effectiveness of the repairs.
- Being a ‘dry’ testing method, ultrasonic testing eliminates the risk of damaging water-sensitive cargo or causing environmental pollution in dock, river, or sea water.
Moreover:
- Ultrasonic testing is a swift and uncomplicated process, requiring no assistance from the ship’s crew other than supervision and safety measures.
- Downloadable test results provide ship operators with detailed reports for their records.
- The flexibility of ultrasonic testing equipment allows for usage in loaded or empty holds, enabling cover repairs during loading and subsequent checks during or after the loading period, but before departure.
