Introduction
The compactness of the Kongsberg EM 3002 multibeam echo
sounder is a guarantee for a fast and easy installation. For a
surface vessel, the Operator Station and Processing Unit are
placed inside the vessel while the Sonar Head is mounted so that
it is always submerged in water with a mounting angle in
accordance to the system mission.
Operator Station
The Operator Station is a ruggedized PC workstation, prepared
for mounting in a standard 19” rack (requires 4 rack height
units). It is supplied with a rackable 17.4” industrial LCD
monitor, a keyboard and an optical mouse. A bracket for the
monitor is included for table top, bulkhead and roof mounting.
Processing Unit
The Processing Unit may be mounted in a standard 19” rack
(requires 4 rack height units).
On large vessels the Processing Unit may have to be mounted in
a different location closer to the Sonar Head due to the restricted
length of the cable connecting the two units (15 m standard
length extendable to a maximum of 45 m) or a fibre optic link
may be used.
Solutions for mounting the Processing Unit in an underwater
vehicle may be discussed.
Sonar Head
The EM 3002 Sonar Head must be mounted so that it has a clear
view of the bottom, i.e. no obstructions are permitted within a
sector of minimum ±75° acrosstrack and ± 30° along track with
respect to the face of the Sonar Head as seen from the
transducers.
For standard mapping purposes the Sonar Head should be
aligned with the keel line, and not be tilted more than about 10°
forwards or 40° to the side.
It is important that the Sonar Head is mounted so that the water
in front of the head is not aereated. On most vessels a suitable
location would be near the keel in the forward part of the vessel.
An arrangement for streamlining or mechanically protecting the
head may be added, but would normally not be required. Flush
mounting in a well may be used for a permanent installation.
