Installation steps
The following steps must be taken to install the EM 122 transducer arrays
1
Determine the physical location of the transducer arrays under the vessel’s hull.
• This is briefly explained in the previous chapter.
Note
It is important to minimize the alongship gap between the RX and the TX arrays
to improve the performance at very shallow water (to get overlap between RX and
TX footprints).
2
Design the transducer installation method.
• Several methods may be used: blister, gondola, flush mounting, external
mounting with fairing(s). The method must be chosen according to the vessel’s
hull design.
• On an ice capable vessel or an icebreaker, the transducers will normally be
incorporated into the hull. The transducers must be protected with ice windows.

3
Prepare the transducer array installation arrangement.
• The installation arrangement must be capable of accepting the two transducer
frames.
4
Verify the alignment of the mounting frame foundation.
5
Install the steel conduit(s) that will take the transducer cables up inside the ship to
the TRU.

6
Mount the transducer frames.
Align the frames.

7
Mount the transducer modules into the frames.
on page 32
8
Lay the transducer cables from the transducer modules to the steel conduits.
Each cable is marked in both ends with the module’s serial no. and the cable no.
9
Pull the cables up through the steel conduits.
10
Seal the steel conduits on top. This is done by the shipyard. The transducer cables
are designed to lay in water and the area around the transducers and the steel pipes
shall be water filled.
