Key Benefits

Prevent Cargo Damage

Water ingress through leaking hatch covers is a leading cause of cargo damage. For ship owners, managers, and insurers, ensuring the cargo hold is watertight is crucial. Leaks often lead to costly claims against insurance companies and P&I clubs, making it essential to prevent water damage before it happens. Protect your bottom line with a guaranteed, reliable solution!

Reliable Hatch Testing

CARGO-SAFE™ is an ABS Type Approved hatch cover tester, trusted for its precision and reliability. The Probador ultrasónico de tapas de escotilla CARGO-SAFE™ offers a fast, simple solution to verify the weather tightness of hatch covers, bow, stern, and side doors. Unlike traditional hose testing, it leaves no environmental impact on ports or harbors and can even be used in sub-zero temperatures, ensuring flawless performance in any conditions. Protect your cargo and the environment with CARGO-SAFE™!

How It Works

Super Easy To Use

The principle for ultrasonic 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 problem can be established from the strength of the signal detected.

From Box To Survey in 5 Easy Steps

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

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

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.

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.

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.

In the field of ultrasonic hatch cover testing, the importance of a powerful transmitter cannot be overstated. Imagine the hold of a cargo ship a vast space comparable in scale to a grand church or mosque. To thoroughly inspect it for potential leaks, ultrasound technology is essential.

The key to effective leak detection is the ability to detect even the faintest ultrasound emissions. Compliance with regulations requires precision within a margin of just +/-1%. Achieving this level of accuracy demands a significant Opening Hatch Value (OHV), measured in decibels. The strength of this value is crucial; if it’s too low, the results will be inaccurate.

Class Instrumentation Ltd’s Cargo-Safe is the most powerful ultrasonic transmitter available, with an impressive output of 157 decibels, making it unmatched in the market. To explore its full capabilities, visit here.

Achieving a consistent ultrasound level throughout the vast expanse of a cargo hold on a bulk carrier presents a significant challenge. Not only does it require substantial power, but also a method to evenly disperse the energy emitted from the transmitter to uniformly saturate the area. The arrangement of the 13 emitters on the transmitter must therefore be meticulously designed to emit energy in a precise pattern for effective distribution.

Class Instrumentation Ltd has perfectly engineered the positioning and angles of each of the 13 emitters to tackle this complex task with precision ensuring optimal performance. https://www.classltd.com/cargo-safe-ultrasonic-hatch-cover-tester/

Ensuring prolonged battery life is crucial when conducting leak detection on hatch covers aboard a bulk carrier. Avoiding the inconvenience of battery changes is paramount. At Class Instrumentation Ltd, we’ve integrated a proprietary circuit designed to sustain transmitter power consistently, regardless of battery voltage, until only 10% of battery power remains. This innovative feature extends equipment performance, doubling the operational time compared to conventional circuits. With this enhancement, our equipment can confidently complete surveys on Capesize bulk carriers using just one set of batteries.https://www.classltd.com/cargo-safe-ultrasonic-hatch-cover-tester/

The CARGO-SAFE can be used on any vessel between Handysize to Capesize. For vessels smaller then Handysize we recommend our DOOR-SAFE or CABIN-SAFE products.
