1. General information
The SKIPPER ETNSTCI/ETNSTCILF combo ice/sand protection tank is used for installation of:
1. Echo sounder transducer type (24, 38, 50 and 200 kHz).
Caution!
Be aware that the transducer contains high precision parts and therefore proper
handling when mounting is essential for the nal result.
First of all, it must be decided where the tank should be installed. Normally, this will be in the fore part of
the ship, in the centerline, or as close to the centerline as possible. Optimal system operation is achieved by
tting the transducer as deep as possible on the hull.
• The active surface of the transducer must be installed with front face a maximum of +/-7 degree to the
ships horizontal plane.
Do not mount sensor/transducers close to the bow thruster propeller outlets, or aft of other hull installations
(outlets, vents or other protruding details) who may create aeration or turbulence.
It is necessary to select a part of the hull that is submerged and free from turbulence and aeration under all
load and speed conditions, and to avoid positions where air is trapped in heavy weather.
If a at, horizontal section is not available for the transducer tting, the shipyard must construct a suitable
bed. Welding seams in this area should be smoothed and rounded o, in order not to create turbulence or
aeration at speed.
Protect the active element of the transducer during transport and installation, and
do not paint the surface.

ETNSTCI/ETNSTCILF Installation Manual
Important
To comply with POLAR class requirements the Echo sounder transducer should be installed below
any ice belt
An echo sounder transducer installed into a tank with ice protection plate in front will have certain
disadvantages compared without a plate
• The plate will decrease the acoustic signal and decrease the general performance of the Echo
sounder
• The area between transducer and protection plate must be lled with water with no air bobbles
present at all time when echo sounder is in operation. Transducers pinging into air bubbles may
become defective after few minutes of operation.
To install the transducer in a tank with ice protection plate in stead of in a sea valve ush with
the hull result in worse performance (still inside IMO requirement) and higher risk of transducer
damage. Transducer damage in a tank with Ice protection is normally not covered by any SKIPPER
warranty.
”Transducers for Echo Sounder are delivered with a xed cable. Needed attention must be taken to
allow easy replacement/pulling of new cable during maintenance”.
SKIPPER Electronics AS will recommend installation positions if GA-drawings (General
arrangements) and frame drawings are made available for study.
Condition.
The welding to hull structures and structural support of the items may be subject to separate approval by
classication societies for each installation on board a ship.
Standard welding practice, methods and procedures should be observed, but may vary. (See welding notes).
Welding notes!
All bottom parts and anges for welding are precisely machined parts. During welding of these parts
to the ship’s hull plates, careful attention must be paid to avoid construction strain on the bottom
parts and anges.
• Let parts cool down during welding.
• Over heating may change t and form and result in non-conformity with intended sensor/
transducer.
• Welding to thick hull steel plates will exert high stress on bottom parts and anges.
• Especially care must be taken during welding of stainless steel anges.
• Work must be performed by a qualied and certied welder.

9. Bleeding the tank
After undocking of the ship, it may be necessary to open the cable gland on top of the cable pipe to bleed out
the air to ensure that water will ll the transducer tank. If the tank is not lled with water, the performance of
the transducer will be heavily reduced.
Note: Air can be trapped inside the tank due to aerated water/airbubbles from heavy seas, thrusters etc.
Routine for bleeding the tank /cable pipe should be considered.
The message “Lost bottom” on the echo sounder screen, in conditions where the sounder should see the
bottom, may be an indicator that the tank needs bleeding.
