Cathelco Middle East has announced the launch in the region of a new ultrasonic biofouling protection, system, USP DragGone. The technology is designed to reduce fuel consumption by 30-40%, while significantly lowering installation costs. According to Cathelco, the system eliminates the need for drydocking, making it a highly attractive option for shipowners.
Chris Hewitt, Product and Technical Manager at Cathelco, comments, “After closely monitoring developments in ultrasonic antifouling technology, we are confident that our patented system offers distinct advantages over existing solutions. Its installation is straightforward, even on the largest vessels, and it effectively prevents fouling from a broader range of species than traditional systems.”
Since its launch, the system has already been installed on a variety of vessel types, including ferries, bulk carriers, barges and super yachts.
The system works through acoustic cavitation, with high-frequency sound waves producing microscopic bubbles in the water. When these bubbles burst, they rupture the cells of biofouling organisms through localised pressure changes. This prevents them from attaching to the vessel’s hulls at an early stage.
Unlike traditional methods, ultrasonic antifouling works as a proactive approach instead of being reactive. It is also non-toxic, allowing ship owners to protect their vessels while reducing their environmental footprint, Cavotec states.
