approved by the vessel’s national registry and corresponding maritime authority and/or
classification society. Such approval must be obtained before the installation can begin.
The shipowner and shipyard doing the installation are responsible for obtaining and
paying for such approval.
Important
Finalize the steel conduit installation before you pull the transducer cable through it.
Make sure that there are no spatter, sharp edges or protruding objects that can damage
the transducer cables. If a cable is damaged, and penetrated by water, the transducer
may be damaged beyond repair.
The outline dimensions of the ES18 transducer and the relevant installation items can be
found in the
Drawing file chapter in this manual. End user manuals and source drawings
(normally in AutoCad format) can be downloaded from our website.

Procedure
1 Based on the vessel drawings, the physical properties of the decks and bulkheads,
and the physical locations of the transceiver and the transducer, design the steel
conduit.
The steel conduit must preferably be straight. Start the conduit immediately
above the transducer, and terminate it well above the water line. If you must
introduce bends on the steel conduit, take the minimum cable bending radius into
consideration.
2 Manufacture the steel conduit according to the relevant production standards.
3 Mount the steel conduit.
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.
