Sea-chest entry while drydocking 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[…]
Sea-chest installation One of our earlier bigger professional installations was on the HAM317, a trailing suction hopper dredger owned by Van Oord. We installed 4 transducers of 50 Watt each to protect the some sea-chests. In the videos we still show the old installation method, with threaded rings. […]
Skansi Skansi is a shipping company very keen on innovation and experimentation. Shipsonic has installed various systems for box cooler protection on 2 of their off-shore vessels, the Saeborg and the Sjoborg. First round of trials We started in 2016 installing a number of HDS (Heavy Duty) systems to protect the sea chests and -indirectly-[…]
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[…]
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. […]
Ridas Yachts from Estonia is building a new 115 feet ketch, called Zaca. They will install a Shipsonic HDS40-100. This is a system with 4 transducers of 100 Watt each. The system will be used to protect the hull against fouling.
Transducer location At delta-sistems we feel we have dealt with all the technical challenges in making a reliable, high powered ultrasonic system. One challenge remains, however. This is: where exactly to install the transducers on the object that needs protection? This is an acoustical problem. And acoustical problems are notoriously complex. Finding the solution is[…]
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,[…]
