Designing, manufacturing and mounting the
steel conduit
A steel conduit is used to protect the transducer 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
To design, manufacture and mount the steel conduit, the following prerequisites must be
met:
• 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 has been installed.
• All relevant personnel (naval architects, designers, skilled shipyard workers) and
tools must be available.
