Haiphong Marine offers professional ultrasonic hatch cover tightness testing at all Vietnam ports and anchorages. Ensure watertight integrity, protect cargo, and meet P&I standards 24/7.
Reliable Ultrasonic Hatch Cover Tightness Testing Across Vietnam
In the maritime world, protecting cargo from water ingress is not just a safety measure—it’s a legal and commercial requirement. Haiphong Marine provides professional ultrasonic hatch cover tightness testing for vessels at all major Vietnamese ports and anchorages.
Our certified inspectors use IMO and IACS-approved ultrasonic equipment to identify even the smallest leak paths that traditional hose or chalk tests may overlook. With years of technical experience and full mobility across the country, we help shipowners verify hatch cover integrity efficiently, avoiding costly cargo claims and port delays.
When a hatch cover fails to seal properly, seawater can easily enter the cargo hold—causing cargo contamination, rusting, and insurance disputes. Even a few drops of water can damage thousands of dollars’ worth of sensitive goods.
Ultrasonic testing is now recognized as the global industry standard for assessing hatch cover weathertightness. It offers accurate, non-destructive, and fast evaluation compared to conventional methods.

+ Highly Accurate: Detects micro-leakages invisible to the naked eye.
+ Non-Invasive: No need to flood or spray the hatch area.
+ Environmentally Friendly: No pollution or water waste.
+ Fast Turnaround: Typically completed within 2–3 hours per vessel.
+ Globally Accepted: Recognized by all P&I clubs, insurers, and classification societies.
+ Ideal for Bulk, General Cargo, and Container Vessels.
Haiphong Marine’s mobile inspection team can perform ultrasonic tests both in port and at anchorage.
