It is a great honour for Shipsonic to have been chosen as the most reliable, environmentally friendly and robust anti-fouling for box-coolers. We appreciate the selection process by Van Wijngaarden Marine Services B.V., Kooiman Marine Group and NRF (Nederlandse Radiateuren Fabriek) and we are proud to be part of the Rijnstroom project. Special thanks to Jan Willem Janné and @Martien Beeke. #competitiveprocurement #boxcoolers #ultrasonicantifouling #usaf #marinegrowthpreventi

Finally we received our latest batch of the Ultra Tester© version 1.4.2026. Ever wonder how much sound your ultrasonic anti-fouling actually delivers? The Shipsonic designed (very much by Chiel de Wit), built and copy-right protected device can measure the SPL - Sound Pressure Level. We use this to check if the ultrasonic sound from our transducers is properly transferred into the object we need to protect against fouling. #SPL #soundpressurelevel #effectivenessmeasurement #U

However, however, we install only a small portion of our systems on hulls. Why is that? Two reasons: It requires a very large number of transducers, roughly 2 transducers between frames, on port and starboard. That comes to 4 transducers every 600mm or so. We need to be a

Either they revert to plate-coolers, or they switch to keel coolers. Why are some in the maritime industry unhappy with box-coolers? There are so many advantages to box-coolers, how can the disadvantages make them unattractive to some? Th

Shipsonic noticed that so many stories go around about how marine fouling happens and how ultrasonic systems can fight it. We identified a whole list of stories we heard. Then we put the list to our Director, Chiel de Wit. The result is a wonderful series of short videos giving you honest answers about this theme shrouded in myths and fantasy. The first 4 videos are here: Q1: Some claim that ultrasonic anti-fouling can clean a surface of marine growth. What is Shipsonic’s vi

This photo was taken during one of our recent installations. It shows how Shipsonic’s software can be installed and updated instantly. It also allows the client to reconfigure the system, if he has decided to add additional channels to our modular units. So far we have always been able to guide staff onboard to do this themselves since the software is very user friendly. For the nerds: Shipsonic uses embedded software. This means that our engineers design the combination of h

The more (ultrasonic) decibels you can bring into a seawater exposed surface, the more it vibrates and the better we can prevent biofilm and if there is no biofilm subsequently you cannot have mussel/barnacle/tubewurm infestations. Due to years of painstaking research Shipsonic

That is a myth. Basically, ultrasonic sound cannot even kill any organism, it can only prevent biofilm from settling. 𝘋𝘦𝘮𝘺𝘴𝘵𝘪𝘧𝘺𝘪𝘯𝘨 𝘜𝘭𝘵𝘳𝘢𝘴𝘰𝘯𝘪𝘤 𝘈𝘯𝘵𝘪-𝘧𝘰𝘶𝘭𝘪𝘯𝘨 #USAF #fouling #biofilm #myths

Even the sturdiest, two-component, costly glues have a limited working life in a vessel. To boot, the constant high Sound Pressure Level is also a huge challenge for the glue. Several of our installations took place on vessels where we needed to remove our friends' systems, with transducers hang

It is wonderful for Shipsonic to connect with so many captains, fleet managers, shipping companies and maritime researchers at this sophisticated trade show. Our stand has a real ultrasonic vibe and attracts many genuinely interested people. Two more days to go, looking forward to meeting you there at our stand 3.167 as part of GET STC LTD stand.

Together with Kelvion, Shipsonic has developed test equipment that can measure the actual capacity of a cooler. It measures not only the inlet and outlet temperature of the coolant, but also the speed at which the fluid flows through the coolers.
