Shipsonic and delta-sistems B.V.
Shipsonic is a brand of delta-sistems B.V. a Dutch cleantech company that provides innovative, effective, cost efficient & environment friendly antifouling solutions for professional marine, offshore and fishery. As of January 2017 delta-sistems B.V. has incorporated Shipsonic, since 2006 one of the market leaders in ultrasonic antifouling. delta-sistems B.V. will continue the Shipsonic brand with recently developed and strongly improved series of heavy duty ultrasonic antifouling systems. All Shipsonic systems are developed and built in the Netherlands.
The Netherlands has a rich maritime research and development tradition. At Shipsonic we have made a conscious decision to tap into this. To be able to do this, our systems are fully developed and built in the Netherlands. This allows us to partner with such institutions as the NIOZ (Netherlands Institute for Sea Research) and the HZ Vlissingen (University of Applied Sciences), amongst others. For a more detailed look into our present innovation agenda, go to our Research & Development section.
Shipsonic is looking for dealers worldwide.
Shipsonic is a young company. We were established in 2017. Initially we emphasized the development and testing of our systems. Now it is time to work on growth. As part of our growth strategy, we want to expand our dealer network. If you run -or work for- a maritime supplier or repair company, feel free to contact us. Use the contact form at the bottom of this page and we shall get back to you. We are already sufficiently represented in Norway and the Netherlands.
Installation consulting services
Installing an ultrasonic antifouling system is very simple, and normally carried out by the ship’s crew. The one decision to make is how many transducers are needed, and where to place them. To help clients with this, we offer an installation consultancy service. We let you do the installation, but help you decide how. This service can be hired online, using video conferencing etc. Or one of our consultants comes to visit you on the ship itself.
Permanent, structural client feedback
We find client feedback so important, that any client willing to give us structural feedback on the functioning of his ultrasonic antifouling system, is offered a 30% reduction on system costs. As part of our feedback system, we are the only UAF supplier that hires professional divers to film the state of box coolers and sea chests protected by our systems.

Multiple transducers on 1 object Shipsonic is preparing a project to protect floating windmills against marine fouling. That involves installing a large number of transducers. Our biggest system powers 8 transducers, and our heaviest transducers are 120 Watt. But for this application even that is not enough. We need something bigger. […]
Design philosophy At Shipsonic we summarize our outlook on ship’s technology in two words: no frills. Our systems have to be of the fit-and-forget type. The control unit has only one task, to power the transducers. And it has to do so fail-safe. Therefor we do not take part in a common electronics hype, that[…]
Shipsonic™ has invested considerable resources in developing systems with a guaranteed, consistent effectiveness Correct ultrasonic frequency with sufficient energy Our transducers are 50, 100 or 120 Watts.

Ultrasonic antifouling grows as ‘green’ option for vessel owners
by Susan Buchanan,
Introduction by Susan Buchanan
By using sound waves, ultrasonic antifouling can prevent the growth of algae, barnacles and slime on boat hulls and interiors, and can protect sea chests and box coolers as well. The technology has been employed internationally from Europe to Australia, Japan, Chile and the Caribbean, and implemented on commercial, military and recreational vessels. More recently, these systems have caught on with yacht owners in North America. Fouled, rough hulls can slow boats and increase fuel consumption, and antifouling paints — while effective — can release toxins when a vessel is in the water or when coatings are scraped off in dry dock. Usage of ultrasound has grown following the International Ultrasonic antifouling grows as ‘green’ option for vessel owners by Susan Buchanan Maritime Organization’s ban over a decade ago on organotin in bottom paints, and because of moves to limit copper as an antifouling agent. Ultrasonic systems don’t rely on chemicals that can harm fish and mammals or pollute the air, and they can reduce vessel liftouts for cleaning. The cleaning abilities of sound waves have been recognized since before World War II. Starting in the 1950s, sound waves were utilized for this purpose in the food, agriculture, electronics, medical, aircraft and auto industries. While ultrasound’s marine applications have been acknowledged for decades, usage by commercial vessel operators has only gained traction in the past 15 years. To install a system, transducers are trends & currents Courtesy U.S. Coast Guard www.professionalmariner.com 37 antifouling can keep weeds, barnacles and mussels away without hazardous chemicals, cathodes or paints, (and) with no expensive lift-outs, scraping, high-pressure cleaning or the subsequent disposal of poisonous wastewater.” Impressed current antifouling (ICAF) systems typically use a copper alloy rod to prevent fouling and an aluminum or ferrous alloy rod to reduce corrosion, along with a power unit. Introduced to the market in 2008, NRG Marine’s Sonihull systems produce multiple pulses of ultrasonic energy in a range of targeted frequencies. These pulses are transmitted through the material to which the mounted inside a vessel’s hull, or on other internal features, along with a control box. Onboard generators or shore sources power the equipment.
Susan’s interview with delta-sistems’ Chiel de Wit:
For commercial users, the most common application of ultrasonic antifouling is protecting sea chests, bucket strainers, box coolers, intakes and piping for dry plate cleaners, said Chiel de Wit of delta-distems BV in the Netherlands. “In smaller vessels, we can also protect the hull,” he said.
Box-cooler fouling Box-coolers are essential for a ship’s functioning. However, when unprotected, they quickly lose their effectiveness due to marine growth. Unprotected box-coolers quickly look like this: The pipe bundle of the box-cooler is a very attractive surface for all kinds of marine life: – It has an attractive temperature (normally between 25 and 35[…]
ICAF At present the most effective way of protecting box coolers against marine fouling are the Impressed Current Anti Fouling systems (ICAF). We posted earlier that Shipsonic, together with Blokland Non Ferro, is working on an ultrasonic alternative for box-cooler antifouling. The first prototypes of this new system are now being tested. But[…]
Anti fouling paint To protect the hull of a ship, normally anti fouling paints are used. These paints are biocides, almost all varieties contain copper and/or zinc. In the long run, all these harmful substances end up in the environment. Regulation Regulation of anti fouling paint for ship hulls is increasingly under revision. The chemical[…]
An ultrasonic ant fouling system brings the tube-bundle of a box-cooler, the wall of a sea-chest or the hull of a ship in ultrasonic vibration. This vibration generates an environment in which the larvae of marine organisms do not want to settle. The vibration is so weak, that a large part of the organisms already[…]
