Innovative solutions: the latest Ultrasonic Antifouling System

Biofouling is estimated to add $60-100 billion to commercial shipping costs every year. This includes increased fuel-consumption, drydocking costs, remedial measures and revenue lost due to regular maintenance and downtime.

On hard surfaces in contact with raw seawater, the biofouling process can start in as little as 15 minutes. It starts with the settlement and build-up of slime and soon progresses to algae, weeds and then molluscs.

When marine fouling grows on the outside of a ship's hull, hydrodynamic drag increases which causes fuel consumption to rise. On the inside of a vessel, marine fouling will reduce cooling water flow and lead to major equipment failure if left unchecked.

Eligroup solution:

AN.FO.R.A. is our patented and certified system to prevent the fouling on hull, box coolers, sea chests.

Better hull performance;

Save Fuel;

Reduce lift outs, midseason scrubs and hull re-painting

AN.FO.R.A. Marine Hull protection system utilizes the latest digital electronics and Ultrasonic transducer technology.

The Ultrasonic system works by emitting a specific and scientifically researched low powered pulsed ultrasonic frequencies from a digital control unit, via transducers that are in direct contact with the inside of the hull. The hull acts as a sound board, carrying the sound waves, creating a microscopic environment of moving water molecules over the entire underwater profile of the hull. As a result growth is prevented as the cell structures of the algae and micro-organisms are targeted and cannot survive. While sound waves are resonating throughout the hull form because the transducers are directly fixed to the hull inside, the stern gear (propellers, shafts and drives) are acoustically isolated from the sound within the hull, due to the seals used in their attachment.
