Sea-chest installation

One of our earlier bigger professional installations was on the HAM317, a trailing suction hopper dredger owned by Van Oord. We installed 4 transducers of 50 Watt each to protect the sea-chests. In the video we still show the old installation method, with threaded rings.

New installation method

We have now changed to directly gluing the transducers on the object to be protected. This way of installing transducers is faster and easier.

New transducers

Also, we have upgraded from 50 Watt to 100 or even 120 Watt transducers. Bigger transducers means more sound pressure and lower frequency ranges. Both are good for the effectiveness of the system!
