Transducer blister
The transducer arrays should be mounted underneath the vessel. To achieve this, you can
design and manufacture a streamlined transducer blister, and mount it under the vessel’s
hull. This is a well proven way, when refitting a vessel with a EM 122 system.
A blister is a mounting construction fully welded to the hull of the ship. I contains
casings or boxes, which form the mail part of the unit, housing the transducer frames
and modules. The design is aimed at guiding the aerated water and air bubbles around
both sides of the installation and create an environment around the transducer free of air
bubbles. Blisters of different sizes and shapes have been used from the early days of
echo sounder installation, and this method of installation is a well known principal.
Note
The inside surface of the blister must be protected with appropriate protective paint
and an adequate amount of zinc.
