Secure the steel conduit to decks and/or bulkheads with welds. Observe relevant
requirements and guidelines from the classification society, and make sure that the
conduit is properly supported, strong and watertight.
Note
The quality of the welding is critical to the safety of the vessel. Welding must only
be done by a certified welder.
4 If relevant, allow the maritime authority and/or classification society to inspect and
approve the design and the installation of the steel conduit.
Installing the transducer(s)
The installation of the transducer (or transducers) is a key task for successful use of the
EA640 Hydrographic single beam echo sounder. Not only will you need to penetrate
the vessel’s hull, you must also to select a physical location for maximum performance
and minimum acoustic and electric noise.
Prerequisites
To get a full overview of the installation, you need all relevant vessel drawings. You also
need the drawings provided for each transducer.
Context
Necessary information for the installation of each transducer can be found in the end-user
documentation provided with the transducer.
Procedure
1 Determine the physical location of the transducer.
The decision must be based on:
• The vessel drawings
• The shape and properties of the hull
Make sure that all possible considerations are made to reduce noise.
2 Based on the shape of the transducer housing, and the mounting devices available,
determine the installation method.
3 Design, manufacture and mount the necessary fairing, installation blister, keel box
and/or tank that is required to mount the transducer.
4 Design, manufacture and mount the steel conduit for the transducer cable.
5 Unpack the transducer from its transport crate.
6 Position the transducer under the mounting location.
7 Pull the transducer cable up through the steel conduit.
