Seaplant interview Coltraco about watertight integrity
Please find a preview of the latest published article by Coltraco Ultrasonics, with the full article available at the button below: “With navies such as the Indian Navy and Royal Navy successfully implementing ultrasonic testing of watertight seals as part of their onboard safety management, Coltraco Ultrasonics answer questions about the importance of ensuring watertight integrity to delivering the Safeship®: protecting crew, cargo and vessel.“
Why is watertight integrity an issue?
In 1989 IACS introduced its guidance to owners concerning the care and survey of hatchcovers “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 ship and its cargoes, despite advances in modern shipbuilding technology, construction, navigation and means of preventing ingress of water into hold spaces.”
Other regulations such as SOLAS Reg II-1/11.1 – Initial Testing of Watertight Bulkheads etc requires “a thorough inspection of the watertight bulkheads shall be carried out” using ultrasonic leak test or hose test or equivalent test.
How is ultrasound used to ensure watertight integrity?
The Swedish P & I club recommend using Ultrasound. 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 of the gasket is sufficient. The advantages of using this type of equipment are evident, since ultrasonic tests can be carried out during any stage of the loading without risking cargo damage. The test can also be completed in sub-zero temperatures. The ultrasonic test should be carried out as per the class requirements.”
Which is the best ultrasonic test kit for hatch cover testing?
For 3 simple reasons: “it is faster, better, cheaper” than any competitor. But don’t just take Coltraco Ultrasonics’ word for it, here are 3 customer testimonials:
“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
“The fleet was equipped with a unit per Bulk Carrier and the units are and working well, providing the confidence that there will be no problems with water damage claims.” Ship Management Company
“Our PORTASCANNER WATERTIGHT unit 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
