Watertightness testing

Hatch covers are designed to protect cargo from seawater, rain, and spray. Even minor leakage can damage sensitive or high-value cargo, leading to claims or financial losses. Water ingress through faulty hatch covers can compromise vessel stability, cause flooding in cargo holds, and pose serious safety risks to the vessel and crew. nternational regulations (such as SOLAS and class society rules) require that hatch covers be watertight. Regular testing ensures compliance and helps avoid penalties during port state control inspections. Insurers often require proof of watertightness to validate coverage in the event of a claim. Lack of proper testing and documentation may result in denied claims. Preventing water ingress avoids cargo damage, delays, and costly repairs, thus improving operational efficiency and reducing long-term maintenance expenses.

There are two common methods we frequently use to test the watertight integrity of hatch covers:

1. Hose Test

2. Ultrasonic Test

What Happens in a Product Inspection?

During an inspection, a GTIC inspector evaluates products at specific production stages using a comprehensive checklist.

This checklist is tailored to the product and the client’s requirements.

Our checks typically assess the following:

Specifications
Dimensions
Function
Appearance
Performance
Workmanship

Packaging and packing are also checked, and product-specific tests are usually conducted. Checks can be tailored to the production stage. For example, inspections carried out at the start of production will include checks of raw materials.

We offer off-the-shelf checklists designed to match particular products. If customized checks are needed, you can add to one of these checklists or create your own.
