System with 50 Watt and 100 Watt transducers
The Beyond is a bunker tanker operating from Singapore. An HDS40 was installed, but with 2 sets of different transducers. We installed 2 transducers of 50 Watt and 2 transducers of 100 Watt. The transducers were installed on the sea-chests.
Advantages of different transducers
Different size transducers have different resonance frequencies. This results in a broader frequency range, in this case in the sea-chest wall. Different organisms are vulnerable to different ultrasonic frequencies. Hence, combining different transducer types on one object, is more effective. Lately we have started combining 100Watt and 120 Watt transducers.
