Ultrasonic Antifouling fall under the umbrella of Marine Growth Prevention Systems. The systems make sure that there is no marine growth on the submerged asset.
The OES Group systems produce multiple bursts of ultrasonic energy in a range of targeted ultrasonic pulse frequencies. These pulses are transmitted through the material that the transducer is attached to: your offshore foundation, hull, propeller shaft, pipework, water-jet, sea chest etc…
The pulses produce a pattern of positive and negative pressure on the surface of the material being targeted. Microscopic bubbles are created during the negative pressure cycle, which then implode during the positive pressure cycle.
This microscopic agitation has a cleansing effect that destroys surface algae, always the first link in the marine food chain. Disrupting the food chain keeps the surface clean and makes it much less inviting habitat for larger organisms that feed on the algae. As well as inhibiting the creation of biofilm, the microscopic movement of the water prevents barnacle and mussel larvae from embedding on the surface.
