Our focus

As an young cleantech company we focus on continuous improvement

An ultrasonic antifouling (UAF) system brings the tube-bundle of a box-cooler 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 organisms already present, survive. At a distance of around 20 meters or so, the ultrasonic ‘sound’ has dissipated. The impact on the environment is absolutely zero. Click the icon to read more.

highly effective

The effect of ultrasonic vibration as a blockade for marine growth has been known since the early 1950’s. Given the many advantages this technology has, compared to conventional anti fouling systems, it is surprising to see it is not yet widespread. This probably has to do with the effectiveness of the technology, which is not always consistent. Click the icon to read how Shipsonic has developed systems that are consistently effective.

cost efficient

Ultrasonic Antifouling Systems can be installed while the ship is moving in the high seas. No special tools or dry docking needed. No moving parts either, so hardly any wear and tear. And maintenance free. This makes the ultrasonic solution extremely cost efficient. Click the icon to read more.

About US

Shipsonic and delta-sistems B.V.
Heavy Duty Ultrasonic Antifouling solutions in the best Dutch maritime engineering tradition.

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.

  • Permanent innovation

    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.

  • Global agents network
  • 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.
