1. General
The siting of the SAL R1E transducers is an important factor in determining the accuracy and
efficiency of the overall system.
The transducers are designed to be fitted flush with the hull. One of the tranducers measures
the sea depth (ES = Echo Sounder) and the other transducer measures speed through the water
(SL = Speed Log) in the water mass approximately 130 mm below the ship’s hull.
NOTE: The R1a Speed Log transducer is tested with the cable as one unit. Do not cut or
modify the transducer cable. The relative speed measurement operates at a frequency where
cable length affects performance. Consilium Marine & Safety AB takes no responsibility in
case of cable modification.
The steel bottom flange is welded into a cut-out in the ship’s bottom hull plate. The bottom
flange, including the guide ring, holds the transducers flush with the underside of the hull.
The Top Assembly of the sea valve makes it possible to maintain and change the transducers
without dry-docking the vessel.
The connecting tubes hold each transducer in its intended and fixed position.
IMPORTANT!
When welding the bottom flange to the hull the Red markings on the flange must be assured
to point in the ship’s forward direction!

2. Transducer location requirements
1. To achieve the best performance of the R1E system, special care must be taken to find the
best area in respect of water streaming under the transducers. The transducer location
SHOULD BE REVIEWED AND COMMENTED BY CONSILIUM MARINE &
SAFETY AB in terms of the hydro-dynamical conditions, otherwise the guarantee for the
log system will not be valid. Early discussions on transducer location with drawings are
always recommended. The hydro-dynamical review given by Consilium only concerns the
above requirement and not the inside design, such as installation height, access to closing
valve or any inside obstacles that might occur and jeopardise the function or maintenance.
For more detailed installation advices please refer to the complete manual.
2. The SAL R1E mounting set should be installed in the foremost part of the vessel as close
as possible to the keel line.
3. The SAL R1E mounting set should always be installed perpendicular to the ship’s
horizontal plane.
4. The SAL R1E mounting set and transducer cables are not intended for submerged
mounting in a water filled tank. If no other alternative is available a separate watertight
(W.T.) compartment must be arranged housing the SAL R1E mounting set with
transducers. The cables must be run in a watertight pipe conduit connecting directly from
the W.T. compartment to free/dry space where the R1a Speed Log electronics unit (ELC)
and Echo Sounder junction box are normally installed.
5. The compartment in which the transducers are installed may be sealed by a manhole or
hatch but the compartment must always be accessible for service.
6. The transducer cables must not be permanently installed in case of service or replacement
of a defective transducer. Extra cable length shall be coiled.
Do not cut the cable! Warranty is void if cable is cut.
7. Sufficient headroom must be available at the SAL R1E mounting set position to allow for
its fitting and removal/maintenance (see drawing for appropriate bottom part).
8. On tankers the SAL R1E mounting set location is not to be within the EX–area. The
transducers must never come in contact with cargo oil.
9. The R1a Speed Log transducer cable shall run directly to the R1a ELC and must never be
cut off, shortened, extended or by any other mean passing a junction box!
10. In the vicinity of the transducers’ location, the outside of the vessel must be free from
sudden projections, welding joints, steps and sharp edges. Special care must be taken that
no obstacle occurs in the forward vicinity of the transducers. Such conditions will cause
water turbulence, which may give unreliable speed readings from the Speed Log as well
as distorted depth measurments from the Echo Sounder system.
11. Water inlets and outlets may disturb the water flow. Therefore, the transducers should be
located at least 2 m forward of such openings.
12. The transducers (sensor elements) must always remain submerged, even with a minimum
draught in heavy seas.

Boundary Layer
A moving ship’s hull tends to drag a layer of water with it, causing a boundary region around
the hull. The water speed at the hull is almost the same as the ship’s speed, so that the relative
water speed is almost zero. With successive water layers, the relative water speed increases
until, at the boundary edge, the relative water speed becomes equal to the ship’s speed. The
thickness of this boundary layer is not uniform around the ship, and can range from a few
millimetres near the bow to over a metre at the stern on a large ship.
The relative speed of successive water layers is not proportional to distance from the hull, but
follows a curve as shown below:
Ship´s hull
0
U
Ship´s
Speed
V
Inside
Boundary
Layer
Relative water Speed
Outside boundary layer
(Relative water speed = U)
Next to hull: Relative
water speed = 0
At 1/2 boundary layer:
Relative water speed = 90%U
At boundary layer edge:
Relative water speed = 100%U
Noise, Cavitations and Factors Affecting Acoustic Speed Logs
The transducer operates on the acoustic principle and is therefore susceptible to interference
from acoustic (noise) sources. In particular, the transducer should be fitted well away from the
propeller and other sources of noise, to minimise the effects of noise, vibration and
cavitations.
The transducer and electronics unit is designed to respond principally to the acoustic
reflections denoting the speed of the ship. In some situations, however, the system may
respond to false signals that can arise under adverse conditions. All acoustic logs are affected
in a similar way.
3. Maintenance of Bottom Parts
Each bottom part assembly incorporates a zinc ring that acts as a sacrificial anode to prevent
corrosion of the transducer and bottom parts. The zinc ring should be inspected, and changed
if deteriorated, each time when the ship is dry-docked.
When maintaining the bottom parts it is also recommended to inspect and tighten the tube
bracket clamp.
The guide ring, zinc ring or the transducer surfaces must never be painted!

4. Mounting Set Single Bottom Sea Valve (MSSBSV)
The SAL R1E mounting set is suitable for installation on single bottom ships allowing the
transducers to be removed without bringing the ship out of the water (dry-docking).
Sea Valve / Transducers Assembly
The bottom flange must first be welded into a hole cut in the ship’s bottom hull plate. The
hole must be positioned so that the sea valve may be fitted without obstruction.
Cut a circular hole (diameter 250 mm +10/ –0 mm) at the selected transducer position.

Welding the Bottom flange in Ship’s hull
Notes: 1. Welding work should be carried out by qualified personnel as required by the
applicable classification society.
2. The Red markings on the bottom flange shall point in ship’s forward
direction.
3. IT IS IMPORTANT that the outer (bottom) surface of the flange is flush with
the hull plate and exactly vertical/perpendicular. The welded joint must be
ground smooth and flush with the hull and flange. There must be no sharp
edges to interfere with the water flow around the transducers.

Installing the SAL R1E Top Assembly with transducers.
Following procedures require that the ship is still in drydock and the Sea Valve is fully
opened to allow proper installation and inspection of result.
1. Fully open the Sea Valve, i.e. approximately 27.5 full turns of the hand wheel from
fully closed to fully open valve gate. Observe the indicator pin and as well the interior
of the Sea Valve to verify!
2. Assure that the Seal 2 is placed on top of the Sea Valve flange.
3. The SAL R1E Top Assembly shall be mounted on the Sea Valve with the Red
marking on the valve cover top pointing in the ship’s forward direction in line with
Red markings on the bottom flange and guide ring. From inside, through the Sea
Valve, also the guide ring can be observed with the smaller hole for the Speed Log
transducer positioned in forward direction.
4. Carefully lift the SAL R1E Top Assembly and lower it into the Sea Valve ensuring
that the above direction criteria are complied with and that the transducers do not
violently hit/touch the valve body during mounting.
5. The two Clamp axles, Pos. 9 above, will find appropriate mating holes in the valve
flange, thus may be temporarily loosely fitted with M16 nuts. At this stage also assure
that the two transducers have located properly in the guide ring and that the valve
cover plate, Pos. 8 above, is mating properly with the Sea Valve flange.
6. If not, slightly loosen the three tube bracket M10 clamping screws/nuts (and possibly
the four M16 nuts on top of the tube bracket) to adjust as might be needed. However,
do not use excessive force!
7. Secure the SAL R1E Top Assembly on the Sea Valve using the two M16 Clamp
axles, the six M16x60 screws and eight M16 nuts and eight M16 lock nuts.
8. ENSURE that the transducers are correctly seated at their lowest possible position and
VERIFY this by checking the transducers from outside the ship’s hull.
9. The connecting tubes shall now be approximately 62 mm height over the tube bracket
as indicated in the figure above.
10. The Sea Valve shall always remain in fully open position when the transducers are in
operational position, i.e. down and seated in the guide ring. The Sea Valve may only
be closed when both transducers are retracted to a position above and clear from the
Sea Valve gate.
Note!
IT IS IMPORTANT THAT THE TRANSDUCERS ARE CORRECTLY SEATED AND
FLUSH WITH THE GUIDE RING AND HULL OUTSIDE.
Re-confirm all mounting procedures referring to the picture below and make further
alignments/adjustments as needed and described below.

Orientation of Transducer Connecting Tubes
Turn and fine adjust each connecting tube so that the flat section on the
connecting tubes faces to starboard, SB, and is parallel within ±3° to the keel
line. Use a straight guide bar held against the flat section to facilitate this.
This alignment is important and critical only for the R1a Speed Log
transducer, although same procedure may be used also for the Echo Sounder
transducer.
Tighten the three M10 tube bracket clamping screws to hold the connecting tubes.
Tighten the four M16 nuts holding the tube bracket Clamp axles in position.
To be absolutely sure that the transducers are correctly seated and FLUSH WITH
THE HULL, this must be verified from outside the ship. If necessary, this must be
readjusted also after the above alignment procedure.
