Installing the transducer on a blister or drop
keel
When all the preparations have been made, observe this procedure for the mounting of
the transducer If required, additional and more detailed procedures must be provided by
the installation ship yard.
Prerequisites
• The physical location of the transducer has been determined.
• The steel conduits are installed.
• A suitable fairing is designed and mounted.
Note
Whenever relevant, all drawings as well as the physical installation of each device must
be approved by the vessel's national registry and corresponding maritime authority
and/or classification society.
The following special tools are required for this installation:
• Torque wrench for the mounting bolts
• Loctite 270 (permanent high-strength threadlocker)
Context
This installation arrangement assumes that you can access the inside of the blister or
drop keel to mount the nuts. If this is not the case, the transducer must be mounted with
threaded steel rods welded to the bottom of the blister.
