In the maritime industry, ensuring the watertight integrity of doors is paramount for the safety of both vessels and their crews. Traditional testing methods, such as the chalk test and hose test, have proven to be inadequate and outdated.

Here we take a further look at the drawbacks of these methods and highlight the significance of adopting advanced technologies like Portascanner® WATERTIGHT PLUS for comprehensive watertight door testing.

What does a Chalk Test Actually do?

One commonly used but flawed method for testing watertight doors is the chalk test. While it assesses the compression of the door seal, it fails to guarantee actual watertightness.

A compressed seal doesn’t necessarily mean a leak-free seal, especially if the seal is damaged. Relying on the chalk test alone may lead to overlooking critical issues that could compromise the safety of the vessel.

Why using the Hose Test can be risky?

Another outdated method involves the hose test, where substantial amounts of water are sprayed inside the ship to check for leaks. While this test may identify leaks, it comes with inherent risks.

Uncontrolled water exposure can impact machinery, electronics, and electrical systems, potentially causing extensive damage. The hose test, therefore, poses a threat to the system that it aims to protect, making it an undesirable choice for watertight integrity testing.

The Benefits of Using Ultrasound Technology

To address the limitations of traditional testing methods, it’s crucial to embrace innovative technologies. The Portascanner® WATERTIGHT PLUS offers a scientific and non-intrusive solution for inspecting the watertight integrity of doors. This ultrasonic instrumentation is designed to provide accurate and reliable results without the drawbacks associated with chalk and hose tests.

Regular maintenance using the Portascanner® WATERTIGHT PLUS not only ensures the watertight integrity of doors but also helps vessels comply with international maritime regulations. 

Avoiding issues raised by Port State Control and Classification Societies becomes more straightforward when advanced testing methods are employed. Compliance with the Safety of Life at Sea (SOLAS) regulations is essential to guarantee that doors are maintained to the highest standards, reducing the risk of water ingress and enhancing overall maritime safety.
