ULTRASONIC TESTING OF TIGHTNESS OF HOLDS, CARGO HATCHES, CONTAINERS AND OTHER SEALED COMPARTMENTS
 
Our qualified surveyors perform vessel inspections, ultrasonic leak testing and Pre-insurance Inspection with the latest UK-made ultrasonic leak testing equipment: the Cygnus Hatch Sure Ultrasonic Hatch Leak Detector.
 
 
Features of the Cygnus Hatch Sure Ultrasonic Leak Detector:
  • ABS Type Approved (Download Certificate of Approval) and accepted by P&I Clubs
  • Lightweight (only 3.8 kg) - suitable for hand carry
  • Digital controls for calibration
  • The value of the open hatch (OH) and the sound level in decibels (dB) are displayed simultaneously
  • Powerful and reliable transmitter
  • Convenient transportation in a backpack
  • The transmitter has 6 preset power levels, allowing it to be used in confined spaces.
  • The transmitter is equipped with a shoulder strap for convenience and safety
  • Verification can be performed with a loaded hold
  • Allows you to quickly and thoroughly check the tightness of closing the hatch cover
  • Environmentally friendly
  • Can be used at low temperatures

The Cygnus Hatch Sure Ultrasonic Leak Detector provides an efficient and rapid assessment of hatch tightness to prevent water or moisture from entering through leaking hatches, resulting in cargo damage.

The system consists of a transmitter, which contains of a generator with 19 ultrasonic emitters (40 kHz) and is powered by a battery. These emitters have a special distribution pattern - the reproduced sound field equally covers the entire control area, and the receiver records the ultrasonic signal that penetrates through the slots and allows you to quickly and accurately determine the areas of leaks.

The generator is placed inside the hold, and then, using the receiver, the signal level is compared with the hatch cover open and through the seals of the closed hatch cover. If the signal level at the closed hatch cover is more than 10% of the open signal level, the hatch is considered leaky.

The Cygnus Hatch Sure ultrasonic leak detector is designed:

  • to assess the tightness of ship hatches
  • for inspection of tank hatches
  • for testing for leaks on large yachts
  • for testing waterproof doors
  • for inspection of sealing of sealed doors and hatches
  • for use in confined spaces
  • for any closed systems without excessive pressure / vacuum
