Hatch cover tightness testing is a non-destructive method applied to check the water- and air-tightness of ship hatch covers and to ensure cargo safety.
During the test an ultrasonic transmitter is placed inside the hold and the covers are closed. The perimeter of the cover is then scanned with an ultrasonic receiver so that potential leaks at gaskets and joints are detected precisely, and the results are reported in detail.
Typical Applications
- Ultrasonic hatch cover tightness testing
- Gasket and compression-bar leak detection
- Cross-joint and drainage channel checks
- Pre-loading watertight integrity verification
- Bulk carrier and general cargo vessel surveys
- Class and P&I documentation support
Why Hatch Cover Tightness Testing?
- Objective, quantitative leak location
- No water or chalk needed — clean and fast
- Cargo hold can be tested without flooding
- Report accepted for class and P&I purposes
