Designing, manufacturing and mounting the
steel conduit
A high quality transducer cable is used between the transducer and the transceiver. In order
to ensure a safe installation, a steel conduit must be installed for this cable. The conduit
serves two purposes. It will protect the cable, and shield it from electric noise. Depending
on how the steel conduit is terminated over the transducer, it may also secure the watertight
integrity of the vessel.
Prerequisites
• All relevant vessel and transducer drawings
must be available.
• All relevant work instructions, procedures
and standards must be available.
• The physical location of the transducer has
been determined.
• The installation method has been
determined.
• The cable gland (stuffing box) has been
installed .
• All relevant personnel (naval architects,
designers, skilled shipyard workers) and
tools must be available.
