Today the Dutch algae control company, LG Sonic has received an official order from the Royal Netherlands Navy to apply their ultrasound technology on a marine vessel to prevent the growth of biofouling. Before the end of 2016 multiple ultrasonic antifouling systems will be installed on a 130-meter long marine vessel.
Biofouling growth increases the drag on a hull which results that a ship can consume up to 40% more fuel and correspondingly produce 40% more CO2 emissions. The marine industry globally spends billions of dollars in addressing fouling, using a variety of protection methods such as coatings. The disadvantage of using these coatings is that it they can either be harmful for the environment, expensive and/or ineffective.
In order to provide an environmentally friendly and effective solution to these problems, LG Sonic, developed a new technology to prevent the growth of biofouling by using specific ultrasonic parameters. In the fall of 2016, a 12-month pilot project will start to apply this technology on a 130-meter long frigate.
The objective of the project is to measure the effectivity of LG Sonic devices as an alternative solution for antifouling coatings. The solution is to deploy multiple systems that transmit ultrasonic waves of specific frequencies throughout the ship’s hull in order to prevent and control biofouling.
Nomination P.J.S. de Jong Innovation award
Recently, the project is nominated for the P.J. de Jong Innovation award, awarded by TNO (Organisation of Applied Scientific Research).
