Flush mounted
With the flush mount method the transducers are installed inside the ship's hull. This
method exposes the transducers to passing air bubbles which might affect the system
performance. The benefit of a flush mounted installation is that nothing protrudes from
the keel.
The transducer arrays may be mounted flush with the vessel’s hull. In order to do this,
the shipyard must design a framework inside the hull to support the casings. The arrays
must then be mounted so that their faces are flush with the outer hull.
Note
This installation method may prove unsuccessful due to aerated water blocking the
signal path to and from the transducers. Thorough research on the vessel’s hull design
and the acoustic conditions must be made before attempting this installation method.
Note
The installation shipyard must provide all necessary installation drawings.
If required, all drawings and documents must be approved by the vessel’s national
registry and corresponding maritime authority and/or classification society.
Such approval must be obtained before the installation can begin. The shipowner
and shipyard doing the installation are responsible for obtaining and paying for such
approval.
External mounted with fairings
The transducer arrays can be mounted directly under the vessel’s hull.
A fairing will usually be added around the transducers to ensure laminar water flow
without any aeration problems.
Installation with fairings has proven successful in former multibeam echo sounder
installations.
Note
The installation shipyard must provide all necessary installation drawings.
If required, all drawings and documents must be approved by the vessel’s national
registry and corresponding maritime authority and/or classification society.
Such approval must be obtained before the installation can begin. The shipowner
and shipyard doing the installation are responsible for obtaining and paying for such
approval.
