A totally new concept for hatch cover tightness testing.

For many years, leaking hatch covers have been vehicles for commercial disasters and even today claims for wet damaged cargo as resulting from leaking hatch covers remain one of the biggest concerns for ship owners, ship managers, cargo interests and their insurers. Owners, P&I Clubs and insurers are faced with several hundred million dollars of claims for wetting damage to cargo on a yearly basis, not counting consequences of wetting damage related problems such as delays, disruption of schedules and investigations.

Now ultrasonic tightness testing can dramatically improve the n° 1 cause for claims each year - simply, accurately and reliably!

It has been proven that ultrasonic tightness testing of hatch covers with the SDT Sherlog product range can dramatically reduce exposure to claims filed against ships resulting from wet damaged cargo simply, accurately and reliably!

This entry-level kit of the SDT Sherlog product range includes:

• SDT FLEX.US receiver, with flexible sensor which allows the operator to bend and flex the sensor to gain access to hard-to reach areas
• SDT 8 MS transmitter
• Noise isolating headphone

Furthermore, the SDT FLEX.US receiver:

• is powered by ordinary AA batteries
• allows accurate and quick pin-pointing of areas where lack of compression exists on basis of an audible signal
• is able to work in the continuous or noncontinuous mode
• has an easily adjustable volume control.

Customer/Operator profile:

This low budget, but robust and reliable equipment is an ideal solution for operators who are interested in quick, reliable and easy detection of leaky spots with a high level of precision.

As detection of leaky spots is based on evaluating the received audible sound only, the Sherlog kit “CADET” combines easy and accurate testing with a minimum of training.

The Sherlog MATE includes:

• High-performance SDT200 receiver
• SDT 8 MS ultrasonic transmitter
• Noise isolating headphones
• Icon based menus for intuitive navigation

• External flexible sensor
• Storage capacity for 4000 time- and date-stamped measurements
• Tailor made DataDump software for data transfer to computer and printing
• Independent adjustments of listening volume and amplification level which enhances user's comfort.

Customer/Operator profile:

The Sherlog MATE is recommended to users who value the importance of both measuring and evaluating the weather tight integrity of hatch covers, as well as the transfer of survey data to their computer to facilitate reporting and record keeping. In order to interprete readings and test results in a correct manner, following the SDT-IMCS training course will enhance understanding and knowledge of the operator.

The Sherlog MASTER includes:

• The ultimate performance receiver (SDT270)
• SDT 8 MS ultrasonic transmitter
• Noise isolating headphones
• Icon based menus for intuitive navigation
• 6 integrated linguistic versions
• External flexible sensor
• Red/green indicator for indicating measurements >10% OHV
• Tailor made DataDump software for data transfer to computer through USB

The Sherlog SDT270 further allows:

• Logging of functional test
• Selecting the number of hatch covers panels
• Navigating on the receiver's display in order to position and log leaky areas
• Indicating additional openings like loading ports, ventilators and access hatches
• Storing of operator, equipment, certificate, port and ship information for inclusion in the final test report
• Immediate generation of a fully detailed, comprehensive and tamperproof test report.

Customer/Operator profile:

In addition to high quality performance, the unique screen navigation feature adds considerably to the user friendly measuring and logging of data during the execution of tightness test on board. Moreover, the enhanced reporting features of the SDT270 allow producing detailed and comprehensive survey reports in MS-Word format immediately after completion of the tightness test which is a major step forward in facilitating the reporting work of every surveyor, consultant or superintendent.
