Intelligent Acoustic Deterrent
SealFENCE is an intelligent acoustic deterrent system (sometimes known as a seal scarer) designed to deter seals and sea lions from underwater areas using a unique ultrasonic transmission.
The system is close range (effective at up to 50m) and uses a proven, physiological technique. SealFENCE comprises a topside control module and a submerged “smart projector” (manufactured exclusively for us by Airmar Technology) that emits the sound. The short range means that a network of modules is required around the farm to create a “fence” of protection.
SealFENCE features a unique Active Condition Monitoring (ACM) System which checks that each Smart Projector is working correctly and displays live and historical performance information on the barge.
SealFENCE is a modular system with each self contained module located on each cage. There are no cables running between cages or between the barge and the cage.
