We pioneered the development of Ultrasonic leak detection technology over 3 decades ago and have been at the forefront of its research, manufacture & supply ever since.
Ultrasonic leak detection can be used to test a whole variety of watertight seals but our main applications include Bulk Carrier Hatch Covers, Watertight Doors, Cable Transit & Pipe Penetrations (MCTs)
The world-leading ABS & RINA Approved Portascanner® WATERTIGHT is an ultrasonic hatch cover tester, test procedures for testing watertight and weather-tight seals. Test the integrity of sealed compartments; watertight doors, hatch covers and multiple cable transits (MCTs).
Owners, managers, marine surveyors, third party servicing companies and other mariners have pledged their support for the Portascanner® WATERTIGHT water ingress testing equipment and Ultrasonic Leak Detector for years.
For three simple reasons: “it is faster, better, cheaper” than any competitor. The Portascanner® WATERTIGHT is the ideal unit to ultrasound test hatch coamings of the hatch cover sealing arrangement. But don’t take Coltraco Ultrasonics’ word for it, here are 3 customer testimonials:
“Our PORTASCANNER WATERTIGHT unit and Ultrasonic Leak Detector performed well during the entire period of use, proved rugged and we feel sure that if it had not required returning for mandatory calibration and certification, the unit would have performed well for many more years to come.” Captain J.F. Holmes, Botrans
“We did some transit inspection work on one of our customers vessel using the Portascanner and we are very pleased with your instrument. We are looking forward extending our service offer using it.” – Techsol Marine, Canada
Captain Peter Machado, Master Mariner, one of our first Fleet users of Portascanner™ Watertight when he was with Kuwait Livestock and Trading said, “COLTRACO’s Portascanner™ is the product that I am happy to endorse having used the product for many years in the challenging environment of large livestock carriers. Watertight integrity was and remains critical as the most recent conversions have been car carriers, container ships and tankers. Portascanner™ is portable, easy to carry and use, and more importantly, very efficient. It is a rugged. Aspects include purchase price at good value, good warranty terms, the availability of spares and service stations at major hub ports.”
The Portascanner® generator is the most efficient of all on the market. Unlike the old “Hedgehog Generator”, the Portascanner® generator has excellent battery life, is light and small, can be magnetically mounted, is highly sensitive and uses smart pinpoint technology to direct ultrasound to the seals during testing and test procedures.
Use the Portascanner® WATERTIGHT hatch cover tester to find hatch leaks and ensure watertight integrity.
In 1989 IACS introduced its guidance to owners concerning the care and survey of hatch covers as follows:
“Loss of weather-tight integrity continues to be a constant factor leading to cargo damage which could result in a threat to the safety of the crew, the vessel and its cargo hold, despite advances in modern shipbuilding technology, construction, navigation and means of preventing ingress of water and sea water into hold spaces, including water tightnes.”
The importance of continually maintaining seal integrity must take a more prominent position in vessel maintenance scheduling as demanded by regulations:
SOLAS Reg II-1/11.1 it states that hatches and watertight seals must be regularly tested: “Where a hose test is not practicable [sic] it may be replaced by [sic] an ultrasonic leak detection test or an equivalent test. In any case a thorough inspection of the watertight bulkheads shall be carried out.”
IACS: Firms engaged in tightness testing of closing appliances such as hatches, doors etc. with ultrasonic test equipment
2.1 Extent of engagement – Ultrasonic tightness testing of closing appliances such as hatches, doors etc.
2.2 Operators – The operator is to have the following qualifications:
2.3 It shall be demonstrated to the Surveyor that the ultrasonic equipment is fit for the purpose of detecting leakages in closing appliances.
2.4 Procedures – The supplier shall have documented work procedures which shall include the manual for the ultrasonic test equipment specified, its adjustment, its maintenance, its operation and approval criteria.
Water ingress on board ships can be devastating, to crew, vessel and cargo.
The Swedish P&I Club have stressed that proper weathertightness is a key factor in keeping cargo dry and crew safe. For ingress protect, watertight hatch doors and hatch covers’ sealing system needs to be in a good condition.
The North of England P&I Club state that defective hatch cover maintenance is an “expensive problem with a low-cost solution”.
Hatch leaks account for 4.56% of the total payouts (of claims between 5,000 and 3,000,000(USD))
The Swedish P & I club recommend using Hatch Cover Sonic Testing for protection against ingress and sea water ingress. As stated in their 2018 report “A much more effective method is to use an ultrasonic device, which is designed for this purpose and can pinpoint the area which is leaking, and if the compression bars of the gasket is sufficient. The advantages of using this type of equipment are evident, since ultrasonic tests and condition surveys can be carried out during any stage of the loading without risking cargo damage. The test can also be completed in sub-zero temperatures.”
Testing of hatch cover sealing arrangement, specially hatch coaming, with ultrasound is a dramatically more sensitive, accurate and reliable method for testing marine hatch covers, bulkheads and doors for watertight integrity on all vessels than the chalk test or a hose test. A multi-directional ultrasound emitter is placed in a hold. The open hatch value being tested is then sealed and the receiver switched on ready to receive any leakage of ultrasound via a set of headphones. An increased reading of ultrasound signal signifies an issue with the integrity of the door/hatch. Further, and closer inspection will allow identification of any specific leakage sight along with the severity. This test will take approximately 10 minutes and requires only one operator.
