Are your Hatch Covers tight?

Following closely the evolution of technology and the surveying requirements of the major P&I clubs and shipowners, InterMarine surveyors have been trained and qualified to carry out Ultrasonic Tightness Tests of Hatch Covers.
In this context, the company has been equipped with the state of the art Sherlog Master Kit.
This 3rd generation model is at the top of the range compared to other models in the market and offers enhanced performance, accurate measuring and instant reporting, minimising the total time required for inspection and reporting.

​The most important benefits of using ultrasonic testing method are:

1. Reliable, Non-destructive, repeatable testing method.
2. Detection of areas where lack of compression exists with pin-point accuracy (no time consuming investigation needed for finding the leaks, as the leak can be pin-pointed local repairs might be sufficient and adequate,….).
3. Information about compression status.
4. Quick and easy testing, without assistance from ship’s crew (except for supervision and safety aspects).
5. Possibility to use the equipment in holds loaded with water susceptible cargo.
6. Possibility to test hatch covers irrespective of weather conditions.
7. Testing for weather tightness and air/gas tightness.
8. Identification of leaks without the use of a transmitter (on condition that the compartment tested for leaks is pressurized (air escaping through small openings, cracks etc… will cause disturbance of molecules/friction which creates ultrasounds that can be detected)
