Hydrophone cable
The trawl hydrophone is delivered with a 22 m cable. The cable
is fitted with plug that fits the ANT socket on the r ear side of
the PI54 Operator Unit. The standard hydrophone delivery
includes cable gland kit 599-202216 for steel hulls, and the
hydrophone cable has been cut to allow this cable gland to be
installed.
General cable gland guidelines
Hydrophone cables ar e passed through the hull using approved
cable glands for the type of vessel in question. The standard
delivery consists of a steel cable gland that is to be welded to
the hull.
A bronze cable gland can be delivered as an option for vessels
with wood or fibreglass construction. Vessel not to be classified
can as an option use a cable gland made of plastic.
Note: Simrad strongly recommends that a length of conduit be fitted
around hydrophone cable glands made of steel or bronze and
extended over the water-line inside the vessel. This precaution
reduces the danger of flooding in the event of gland failure and
hydrophones installed in this manner are also easier to replace.
Some vessels may experience difficulties finding suitable areas
of the hull for mounting hydrophone cable glands due to
existing water tanks, concrete ballast or other obstacles. A
possible solution in such cases is to run the hydrophone cables
in a steel conduit aft along the hull until a suitable cable gland
location is available. The respective cable gland can then be
installed as described in the following instructions.
Note: Simrad takes no responsibility for the correct installation of
cable glands, associated hull modifications and/or structural
support of hydrophone cable penetration. These activities are
subject to individual approval by the respective classification
society for the vessel in question.
