Installing the transducer on a steel hull
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
It is very important that the fairing designed for the installation supports the full length
of the transducer body. Incomplete support will put the transducer.at risk in heavy seas.
The force of the water when the hull falls down may push the transducer up, and may
cause damage both to the transducer and to its mounting.
Note
Kongsberg Maritime AS takes no responsibility for any damages to the transducer, the
cable or the mounting arrangement, caused by slamming.
