Shipsonic is currently selling almost all its systems in just two countries. The maritime industry by definition goes beyond national boundaries. We want to get traction in more countries. Already the nomination (1 of 30 SME companies) gives us access to great export support services: Netherlands Enterprise Agency Coach support us to identify our needs Ministerie van Buitenlandse Zaken (Min. Foreign Affairs) will open its trade support network to us evofenedex gives us a yea

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

While Shipsonic has monitored very carefully on all its installations, even some cases that have been running for more than 10 years, it never observed any metal fatigue. The tube bundles on box-coolers and particularly the thin metal horizontal support pl

As Chiel de Wit explains: if a fishing vessel has fish finders, net management equipment, or a platform supply vessel has a dynamic position system, it may cause interference with Shipsonic continuous ultrasonic sound. To solve this, Shipsonic has a piece of software which can instruct individual systems to skip the specific ultrasonic frequenc

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

Here he discusses why Shipsonic doesn't provide all these frills, including remote control of the system. So the answer boils down to: remote connectivity is very hard on vessels, because the control units are deep down in the e

The Framfjord is a vessel of just 67 meters long. See photo 1 for aft of MV Framfjord in dock in Stettin. The Framfjord was designed for rapid emergency goods delivery all over the world. The Red Cross ordered the vessel to be built in 2006, in Croatia. It was small enough to offload in all types of ports and offloading locations, such as river mouths/estuaries. It has complete independent loading and offloading equipment on board. It was at the same time equipped to be as in

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

Cavitation is '𝘵𝘩𝘦 𝘧𝘰𝘳𝘮𝘢𝘵𝘪𝘰𝘯 𝘢𝘯𝘥 𝘳𝘢𝘱𝘪𝘥 𝘤𝘰𝘭𝘭𝘢𝘱𝘴𝘦 𝘰𝘧 𝘷𝘢𝘱𝘰𝘳-𝘧𝘪𝘭𝘭𝘦𝘥 𝘣𝘶𝘣𝘣𝘭𝘦𝘴 (𝘰𝘳 𝘤𝘢𝘷𝘪𝘵𝘪𝘦𝘴) 𝘪𝘯 𝘢 𝘭𝘪𝘲𝘶𝘪𝘥'.

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
