EM 710
2.6.2 Environmental requirements
Vibrations
If the vibration velocity amplitude at the base of the installed
equipment is expected to exceed 1g in the range 5–50 Hz,
constantly during operational life, special precautions are to be
taken.
Consult the applicable manufacturer’s documentation for shock
and vibration damping of the EM 710 Operator Station and
peripherals.
For more information about temperature and environment, see
Environmental and EMC specifications on page 23
Temperature and humidity
All equipment, unless otherwise specified, must be protected
from temperature extremes and excessive humidity.
2.6.3 Noise sources
The vessel’s hull, rudder(s) and propeller(s) should be thoroughly
inspected in dry dock prior to installation. Roughness below
the water-line, deformities in the shell plating and protruding
obstacles can create acoustical noise. These sources of turbulence
must be smoothed or removed as best as possible. It is especially
important that the propeller(s) is not pitted or damaged.
2.6.4 Dry docking
The Transducer installation must be done when the vessel is in
dry dock. Make sure there is sufficient working space under the
hull for this installation work.
Note
The location of the gondola and/or protection blister must be
noted on the vessel’s docking plan for future reference.
2.6.5 Wiring
All cables between the bridge, the various operation- and
equipment rooms, must be supported and protected along their
entire length using conduits or cable trays. Note that the cables
must not be installed in the vicinity of high-power supplies and
cables, antenna cables or other possible sources of interference.
