Hold inspections

We ensure that vessel holds are ready to receive your valuable cargo by inspecting and verifying the load compartment prior to loading. We will check that the hold is dry, clean, free from rust or rust flakes and paint that could harm or discolor your cargo.

We can, if applicable, chemically test whether the hold is free from previous cargo remnants and residues. The ship’s log is checked as part of our contamination testing, to verify whether there were harmful materials among previous cargoes and we pay special attention to other carried products that may cause problems due to quarantine requirements. The hold is also checked for any damage and repainted areas are reviewed. 

Hose Test and Ultrasonic Test

To verify the tightness of the holds, a hose test can be performed which consists of applying high water pressure to the hatch covers and gaskets, to determine tightness and/or potential defects in the hatches. An ultrasonic leak detection test is a viable alternative to the hose test for testing hatch covers and access hatches for weather tightness, as it accurately locates potential points of leakage. The ultrasonic hatch leak detection involves placing an electronic signal generator –transmitter inside the cargo hold- with closed and secured hatches. A sensor is then passed around the outside of all compression joints. Readings taken by the sensor on the receiver indicate points of low compression or potential points of leakage. Ultrasonic testing overcomes the majority of limitations associated with hose testing and can be carried out when holds are loaded.
