Protecting floating windmills

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.      […]

Measuring signal strength of different transducers locations on a box-cooler

The effectiveness of ultrasonic anti-fouling

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. Their frequencies range from 20 to 40 KHz. Each transducer type has its own response frequency. That is the frequency in which the transducer functions optimally. With optimal[…]

Getting access to the sea-chest is complicated and costly

Cost efficiency of ultrasonic anti-fouling systems (UAFS)

If need be, ultrasonic anti-fouling systems can be installed while the ship is moving in the high seas. It can be installed by the ship’s crew. No special tools or dry docking needed. No moving parts either, so hardly any wear and tear. Hence maintenance free. This makes the ultrasonic solution extremely cost efficient.  […]

Fides; first Blokland-Shipsonic box-cooler ultrasonic anti-fouling test system installed

Box-cooler protection Blokland-Shipsonic have installed their first ultrasonic anti-fouling system. The system is developed specifically for the protection of box-coolers. The installation was carried out by a Blokland engineer. The ship where it was installed is the Fides. The Fides is active in the Amsterdam, Rotterdam, Antwerp (ARA) region. It is a container vessel owned[…]

Nisr (pilot boat Kuwait) equipped with Shipsonic ultrasonic anti-fouling system

Big fouling problems The SL Nisr (Smit Lamnalco) operates in the Persian Gulf, known for its relative severe marine fouling. The LS Nisr is not equipped with a box cooler, but has 2 small inlet chambers, protected with a grate, that lead to 2 strainers which strain the seawater before reaching the plate coolers.  […]

Madagascar (tug); Shipsonic installs another heavy duty anti-fouling system on a SmitLamnalco vessel

              The vessel Shipsonic just finished the hand-over of another heavy duty ultrasonic anti-fouling system for use on a SmitLamnalco vessel. This time it concerns the tug Madagascar, operating in the Persian Gulf, and based in the United Arab Emirates. The system The system installed is a HDS80, the[…]

Ange; Shipsonic antifouling system installed on a competitive regatta yacht in the Mediterranean

Fast yacht even faster The captain of the Ange has just installed a Shipsonic ultrasonic anti-fouling system. The Ange is a competitive regatta yacht, a Beneteau First 40.7, based in Toulon. The system comprises 2 transducers                 Professional marine standards Shipsonic specializes in heavier systems for sea going[…]

Blokland is, worldwide, a major player in maritime cooling technology. Challenge For this project, they will make[…]

Research program with the University of Applied Sciences Vlissingen and the Royal Netherlands Institute for Sea Research

Preparing the research set up at the NIOZ premises Research partners The University of Applied Sciences Vlissingen, the Royal Netherlands Institute for Sea Research and Shipsonic have won a research grant. This research grant is made available by the Dutch Taskforce for Applied Research (SIA KIEM). This is a governmental program to support innovation through[…]

FWN Solide; 7 transducers for box-coolers of

On top of the box-cooler   The Solide was one of our first installations with the transducers directly installed on top of the box-coolers. The transducers are glued on the water covers. Each auxiliary box cooler was equipped with 1 transducer, each main box-cooler was fitted with 2 transducers. Together 7 transducers were installed, on[…]

Box-cooler protection

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[…]

Hull protection

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[…]
