CARGO-SAFE DATA™ Ultrasonic Hatch Cover Tester


CARGO-SAFE DATA has marked us out as the leading provider for sophisticated leak detection. The CARGO-SAFE DATA enabled leaks to be found in a large range of situations from cable transits, weather-tight and water-tight doors, hatches, stern and bow doors up to full size hatch covers for cargo ships. Ultrasonic testing completely replaces chalk or hose testing and replaces it with an environmentally friendly non-polluting fast and accurate digital alternative.

The ABS Approved CARGO-SAFE DATA is the combination of a Cargo-Safe and Door-Safe with the added ability to store data on a memory stick for down loading onto a computer or smartphone. This feature rich product will perform without compromise hatch-cover testing for the largest of ships and water-tight, weather-tight doors and transit testing.

How the CARGO-SAFE DATA™ works

The CARGO-SAFE™ works in a very simple way. After the hatch covers are closed, the transmitter generating an ultrasonic signal is placed in the cargo hold, which then emit ultrasonic waves(the cargo hold can be empty or loaded with cargo).
The surveyor or operator then uses the CARGO-SAFE™ ultrasonic receiver to ‘listen’ from outside of the hold and detect any ultrasonic sounds that pass through any holes in the hatch cover with pinpoint accuracy. The size of the leak can be established by the strength of the signal detected.

The CARGO-SAFE™ hatch cover leak detection system has three levels of emitters: upper, lower and vertical. This means that ALL of the ultrasound is directed to the hatch covers, optimising its effectiveness.

The diagram shows the dispersion pattern of the ultrasonic sound emanating from the CARGO-SAFE DATA™ transmitter.

The CARGO-SAFE DATA™ has a high sound pressure level, so it is ample enough to fill even the largest of holds, to enable reliable and accurate readings.

  1. The CARGO-SAFE DATA™ transmitter is placed in the cargo hold.
  1. On the deck, with all the hatches closed, the microphone and headphones are plugged into the receiver.
  1. The surveyor begins to inspect the hatch, holding the microphone against the hatch seals. Any gaps that either air or water could pass through will also allow the ultrasonic signal to pass through – and be detected.
  1. The display on the receiver shows the decibel level of any ultrasound leaking through the hatch seals. The signal can also be heard through the headphones.
  1. The flexible microphone and the extension arm allow the position of any potential leaks to be identified with pinpoint accuracy. The size of the problem is established by the strength of the signal detected.
  • Carry Case
  • A receiver in a leather case with a waist and neck strap for hands-free use
  • Transmitter in a leather case with neck strap for hands-free use
  • 2 yellow microphones
  • Extension arm with wrist strap
  • Emitter tester (for pre-survey checks)
  • Emergency microphone lead
  • AA rechargeable batteries (6 in the transmitter, 4 for the receiver, and 10 spares)
  • Battery charger

CARGO-SAFE DATA™ can be used to test the tightness and water integrity of:

  • Cargo hatch covers
  • Bow and stern doors
  • Access hatch seals
  • Watertight doors
  • Weathertight doors

The CARGO-SAFE DATA™ was designed for use within the Indian Navy, making it operational even in high heat and humidity.

Unlike hose testing, ultrasonic testing has many benefits and no drawbacks.

  • It is compliant with port and harbour environment management plans
  • It does not pollute the marine environment
  • It can locate holes and tears in hatch seals with pinpoint accuracy
  • It causes no damage to cargo
  • It can be conducted in sub-zero temperatures
  • It can be carried out with the cargo in place
  • It does not interfere with the other crew activities

The CARGO-SAFE DATA™ is sold with a device that can be used to check the emitters, the inspection microphones, the extension arm and the microphone emergency lead (The EMEA Tester). It is recommended that this is complete between each survey to ensure accurate results.

The CARGO-SAFE DATA™ hatch leak detector is calibrated at the factory and we predict it will stay calibrated for 5 years.

The constant output circuitry guarantees that the ultrasonic output of the transmitter is constant throughout the entire battery life. You can see this by the green flashing LED’s.
