CARGO-SAFE™ Ultrasonic Hatch Cover Tester  china flag Français Español

CARGO-SAFE™ Ultrasonic Hatch Cover Tester
Cargo

Overview of UT testing

 CARGO-SAFE™   The choice of marine surveyors across the globe

The ingress of water through leaking hatch covers is a main cause of damage to cargo. It is in the interest of ship owners, managers and insurers to guarantee the cargo hold is watertight, as damaged cargo caused by water leaking through hatch covers often results in large claims against insurance companies and P&I clubs.

ABSCARGO-SAFE™ is an ABS Type Approved hatch cover tester. The CARGO-SAFE™ UT  tester provides a quick and simple method of establishing weather tightness of hatch covers, bow, stern and side doors, but unlike hose testing, has no negative side effects on the port or harbour environment and can be performed in sub-zero temperatures.

• LCD display allows ease of reading in bright sunshine or in darkness.
• LED and sound warning of low battery on the Transmitter.
• Direct access to free technical support for the life of the product.

CARGO-SAFE™ Calibration and Maintenance

The CARGO-SAFE™ ultrasonic hatch leak detection system is sold with a device that can be used to check the emitters, the inspection microphones, the extension arm and microphone emergency lead (The EMEA Tester). It is recommended that this is done before each survey, to ensure accurate results.  The CARGO-SAFE™ hatch leak detector is calibrated at the factory and is predicted to stay in calibration for 5 years. The constant output circuitry guarantees the ultrasonic output of the Transmitter is constant over the entire discharge cycle of the batteries, validated by the green flashing LEDs.

CARGO-SAFE™ Certificates and ABS Type Approval Compliance

Each CARGO-SAFE™ unit is sold with a certificate of calibration and conformity, giving full details of serial numbers and warranty periods. This certificate is evidence of each unit’s calibration and ABS Type Approval compliance.  The CARGO-SAFE™ hatch cover tester complies with the IACS UR Z.17 Directive. The certificate of origin confirms that CARGO-SAFE™ is manufactured in the United Kingdom.

CARGO-SAFE™ After Sales Technical Support

Class Instrumentation Limited guarantees the CARGO-SAFE™ ultrasonic hatch cover tester to be free from defects in materials and workmanship for a period of three years from the date of dispatch for the Receiver & Transmitter units and six months for the accessories. Free telephone and email technical support are available throughout the life of the product.

CARGO-SAFE™ How it Works

How the CARGO-SAFE™ Ultrasonic Hatch Cover Tester Works

The principle for ultrasonic hatch cover testing is very simple. After the hatch covers are closed, a transmitter generating an ultrasonic signal is placed in the cargo hold (empty or loaded with cargo) emitting ultrasonic waves. The surveyor or operator then uses the CARGO-SAFE™ ultrasonic receiver to ‘listen’ from the outside of the hold and detect any ultrasonic sounds that pass through holes in the hatch cover sealing system with pin-point accuracy. The size of the leak can be established from 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 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™ Transmitter. The high sound pressure level is ample to fill the largest of holds enabling reliable and accurate readings.

How it works

Step by Step Guide to a Survey

1. The CARGO-SAFE™ Transmitter is placed in the cargo.

2. On the deck, with the hatches closed, the microphone and headphones are plugged into the Receiver.

3. The surveyor begins to inspect the hatch, holding the microphone against the hatch seals. Any gaps through which air or water can pass will allow the ultrasonic signal to pass and can be detected.

4. The display on the Receiver shows the decibel level of any ultrasound leaking through the hatch seals. It can also be heard through the headphones.

5. The flexible microphone and the extension arm allow the position of any potential leaks to be identified with pin-point accuracy. The size of the problem is established by the strength of the signal detected.
