2. CHOICE OF HULL EQUIPMENT

1. According to vessel size

- Hull-fittings with valve (48.1 RVI - 48.1 RVB) or LENS

. Are used on all types of vessels

- Hull-fittings without valve (48.1 RB - 48.1 RA - 48.1 RBL - 48.1 RI) are used on :

. 500 toners maximum

. Fishing ships not longer than 45m

2. Hull fitting cannot be used in dangerous compartments (fuel, hydrocarbons, chemicals).

3. Hull strength must be checked before installation of hull fitting.

4. Hull fitting must be installed in compliance with the specifications of the ship classification company.

5. Power supply wiring must comply with the specifications of the ship classification company.

Sensor location

The flush sensor must be installed in the foremost area of the vessel, when possible in a perpendicular position in the lower section of the bulb on the keel line. Deviation from the perpendicular measured in relation to the vessel’s center line is not to exceed 5°.

In relation to the port/starboard yaw axis, deviation to a maximum of 30° may be permissible in particularly favorable conditions.

The installation position is to be at least 0.5m from echo sounder transmitter and similar devices;

The sensor must be positioned at least 10m away from corrosion protection electrodes. The maximum AC voltage component of the supply voltage of active corrosion protection electrodes is not to exceed 20mV eff.

The flat sensor surface measures the water speed along the hull. This measured speed is not equal to the vessel's true speed. Measured speed is lower than vessel's speed. At vessel's extreme fore, near true speed is obtained, but towards the aft of vessel speed value differs.

The area along the hull where speed is different from vessel's speed is called the "boundary layer". Its thickness increases from fore to aft. The main cause is water running along the hull, which decreases up front. Because of the hull profile, hydrodynamic penetration coefficient is minimum in the fore.

Speed does not depend on fouling of the hull located in the boundary layer. Therefore, the ratio of the vessel's speed and measured speed is constant.

The sensor must be located near the bow, as far forward as possible. It must always remain immerged (if the sensor emerges occasionally, this can cause a short disturbance which doesn't effect the total distance information).

In order to protect the sensor against docking maneuvers, it is recommended to weld two strips on both sides of the sensor close to the hull-casing flanges. In order to avoid hydrodynamic disturbances, it is strongly suggested to profile these strips. Their dimensions will be calculated depending on the desired protection.

03MU002- D – Page 9



The line joining the electrodes of the sensor must be perpendicular to the vessels longitudinal axis.

ATTENTION : It is mandatory to install the sensor in a dry area. In case of sustained immersion, it is strongly advised to use a special watertight sensor.

For vessels with a bulge bow, the area located within distance equal to twice the height of the bulge can be disturbed. The sensor must be preferably located in the bulge. When it is not possible to install the sensor up front, it is recommended to fix it on a streamlined bulge.

For special installation cases (bow thruster...), please contact an I2E/BEN Marine certified agent.

When the sensor is to be retracted from inside the hull, which is the general case, make sure that the sensor location is easily accessible, avoiding costly and long operations. Cargo holds, for instance, cannot be considered as accessible ; in this case, an I2E/BEN Marine certified agent will advise you.

General rules for sensor installation

Before proceeding or drilling, etc. make sure that there is room enough for retraction of the sensor and vital service work. If the hull plating is not flat enough at the selected area, it is necessary to flatten the hull or fit a flattened hull reinforcement.

Welding the hull casing to the hull requires special care. For welding to a carbon steel hull, use electrodes in austenitic alloy : 24 Cr, 12 Ni, 3 Mo or 20 Cr, 12 Ni, 3 Mo". Welding will be preferably made in argon atmosphere.

All BEN hull-fittings are fitted with a plastic outer cap (part n°16 on drawing D0343). This

part is vital and shall be carefully put in place and sticked using tightness cement during

installation. If broken, replace it immediately. A spare outer cap is always supplied either with the fitting or with the spares.

Fibered plastic or sandwich hulls : plastic hulls are not as resistant to screw pressure as metallic ones. Concerning sandwich hulls, the sandwiched materials must be replaced by a solid wooden ring or the equivalent. On standard plastic hulls, a large surface metallic washer can be placed inside and outside, under the condition that it is covered with plastic material joined smoothly to the hull surface. Tightness between hull and washer must be assured. For this type of hull, the inner part of the drilling must be covered for tightness by self polymerizing polyester.

03MU002- D – Page 10



For wooden hulls, hull thickness (including the reinforcement) must be less than the total thickness the hull-fitting can tolerate. I2E/BEN Marine has developed systems for different thickenesses of hulls. Contact an I2E/BEN Marine agent for further information.

Anti-fouling paint must not be removed by abrasion. In certain cases, it is neither possible nor recommended to put the sensor immediately in its working position. In this case, it is necessary to prevent sensor (and connected-cable) damage until it is put in its final position.

When installation is over, do not forget to clean the sensor.

2.1 SCREWED-TO-HULL-FITTING WITH VALVE TYPE 48.1.RVB WITH 48.1.RVB16

SENSOR OR 65.1.RVB WITH 65.2.RVB.20 SENSOR

(Drawing n° D0342)

Steel hulls may be too thin and require suitable reinforcement : minimum total thickness must be 25 mm.

Check that actual thickness of the hull (including the reinforcement) is less than the tolerated thickness.

Note : Reinforcement is always recommended on any type of hull.

1. Remove the sensor from the hull-fitting and from piece (16). Remove the 0-rings.

2. Drill a 64.5 mm diameter hole in the hull for 48 sensors or 93 mm diameter hole for 65 sensors. Remember to flatten external surface in order to get a perfect bearing of piece (1).

For plastic hull, take into acount the instruction § “ General rules for senser installation ”.

Do an external chanfer (about 5 mm - 45°) for easy mounting and proper positioning of piece (1).

Safety of the vessel deperds from Installation.

3. Position hull casing (1) and use self polymerizing mastic for tightness (rubber, silicone rilsan for example). Mastic layer must be thin. Let is harden to a pasty consistency.

4. Screw casing nut (2) on hull casing, and torque it with hammer or caulking tool. To avoid the hull casing from unscrewing, block it with a wedge.

03MU002- D – Page 11



5. Screw the four thru-bolts ref (3) into the nut threaded holes (piece ref. 2) and butt them firmly against the hull plating in order to prevent future unscrewing of the nut. Safety is increased if a blind hole of a few mm depth is drilled facing the bolt. For plastic hulls, it is recommended to glue the nut to the hull with polymerizing fibered polyester.

6. Clean and grease 0-rings (11) an (12). Put them in place. Install the gate valve and properly adjust it (with regard to thru-bolt ref.3).

7. Put the upper 0-ring (6) in place in its landing, suitably greased. Install the upper flange

(5).

8. Screw the safety nuts (19) on thru-bolt (3) forcing moderately and equally.

9. Put 0-ring (13) in place.

10.Fill the inner part of outer bush (16) with self polymerizing silicone rubber such as

"syntofer". Remember to fill only the part indicated on D0342 drawing.

11.Introduce isolating part ref (16) with force. Make sure that it is properly positioned. Check that nothing protrudes and try to introduce the sensor from the outside. Let the mastic harden.

12.Grease flat seal (7) and put it in place.

13.Carefully lubricate the sensor and introduce it in its proper location. Take care to not grease the electrode.

14.Use grease supplied with spares. When properly positioned, the sensitive surface of the sensor protrudes at least 1 mm from external bush, and the red mark on the sensor head is directed towards the bow.

15.Fix sensor flange (8) with screws (9) and washers (20) ; put circlip 15. Connect the link

(10). Check link length : it must be long enough to allow closing of the valve and short enough to prevent sensor from escaping and passing over 0-ring (6).

When using anti-fouling paint,

DOT NOT PAINT THE ELECTRODES - DO NOT GREASE THE

LECTRODES

Note : to avoid sensor damage, it is recommended to put sensor in place just before departure, or while at sea (in this case, do not forget to close the valve).

2.2 WELDED-TO-HULL-FITTING WITH VALVE TYPE 48.1.RVI WITH 48.1RVB. 16

SENSOR OR 65.1.RVI WITH 65.2.RVB.20 SENSOR

(Drawing n° D0343)

Drill a 77 mm diameter hole in the hull for 48 sensors and a 92 mm diameter hole for 65.2 sensors. Do an external chamfer of 5 mm (45°) for welding.

Prior to weld in the hull casing (1) the hull fitting is to be fully dismantled and O-rings are to be taken off.

1. Hull-casing (1) must be properly positioned, follow suggested procedure on drawing C1287. Weld the hull-fitting to he hull. After three or four spots have been welded on the internal side of the hull, remove the tools. Check that the lower part of hull-casing (1) does not protrude the hull, and grind the external seam flush with the hull.

IMPORTANT : Hull-fitting mechanical tolerances are very precise. In order to avoid any possible damage, do not heat the hull-fitting when welding it.

2. Weld piece ref (2) on hull-casing (1).

3. Weld the four try-bolts (3) on lower flange (2) - might already be done in factory -

4. Clean and oil up bearing surface of 0-ring (11) and (12). Put them in place. Install and position the gate valve (4).

5. Put 0-ring (6) and position upper flange (5).

6. Screw nuts (19) - do not forget the washers (18) - on the thru-bolts (3).

7. Put the lower 0-ring seal ref (13) in place.

Fill the inner part of the outer bush ref (16) with self polymerizing silicone rubber. Be careful to not over fill. Force the isolating part inside and clips it. Check positioning of hull-casing and also check that nothing protrudes inside by carefully introducing the sensor. Let the paste harden the time required.

8. Put flat seal (7) in place. Carefully lubricate the sensor and introduce it. Use grease supplied with spares.

9. When properly positioned, the sensitive surface of the sensor protrudes at least 1 mm from external bush, and the red mark on the head is directed towards the bow.

10. Fix sensor flange(8) with screws (9) and washers (20) ; put circlip 15.

11. Connect the link (10). Check link length : it must be long enough to allow closing of the valve and short enought to prevent sensor from escaping and passing over 0-ring (6).

To avoid sensor damage, it is recommended to put sensor in place just before departure, or while at sea

(in this case, do not forget to close the valve). When using anti-fouling paint.

DO NOT PAINT THE ELECTRODES - DO NOT GREASE THE ELECTRODES

03MU002- D – Page 13



2.3 SCREWED-TO-HULL-FITTING WITHOUT VALVE TYPE 48.1.RB OR 48.1.RBL

WITH 48.1.RB OR 48.1.RVB SENSOR (Drawing n° C1285/C1301)

Above fittings are in bronze (48 RB) or in aluminum (48 RA) according to the sensor material

(C1287). Those fittings are convenient for hulls not over 30 mm thickness, including hull reinforcement. Minimum clearance for sensor retraction is 150 mm distance from inside hull.

For thick hulls, a longer hull-fitting has been designed (see drawing C1285 ; 48 RBL hullfitting). This hull-fitting concerns only wooden vessels. Maximum thickness of the hull is 110 mm. Minimum clearance for sensor retraction is 410 mm. A threaded cap ref (25) is supplied with the hull-fitting in order to obturate the opening when the sensor is removed.

1. Drill a 64.5 mm diameter hole in the hole for 481 sensors. Remember to flatten external surface in order to get a perfect bearing of piece (1). Do an external chamfer (about 5 mm -

45° -) for easy mounting and proper positioning.

2. Position hull-casing (1). Tightness is obtained by a self polymerizing silicone rubber in order to prevent rotation of the body when unscrewing.

3. Fill the inner part of outer bush ref (16) with the mastic mentioned above. Be careful to fill only the part indicated on drawing C1301. Force the bush, check that the bush is properly clipsed and that nothing protrudes. Test the clearance by introducing the sensor preferably from outside. Let the paste harden.

4. Put the washer (24) and the nut (23). The nut (23) must be locked by a conventional mechanical system (refer to the drawing). As to the RBL hull-fitting, it is possible to add a second nut acting as a lock-nut (see drawing C1285).

5. Position 0-ring (13) - previously greased - and flat seal (7) and carefully introduce the sensor.

Take care to not grease the electrode.

Use grease supplied with spares.

When using anti-fouling paint,

DO NOT PAINT THE ELECTRODES.

Attention : Red mark on sensor-head must be directed towards the bow.

6. Screw sensor nut (8). Do not forget the circlips (15).

DO NOT GREASE THE ELECTRODES

(Drawing n° C1287)

1/ Drill a 77 mm diameter hole in the hull. Do an external chamfer of 5 mm (45°) for welding.

2/ Position hull-casing (1). To obtain accurate positioning, follow suggested procedure on the drawing. After three or four spots have been welded on internal side of hull, remove the mechanical system and check the positioning. Hull-casing must be flush with the hull. After welding, grind the external seam on a level with hull surface in order to allow piece (16) to butt on piece (1).

IMPORTANT : Hull-fitting mechanical tolerances are adjusted. In order to avoid any destroying risk, do not heat the hull-fitting when welding it.

3/ Fill the inner part of outer bush ref (16) with self polymerizing silicone rubber. Fill only the part indicated on the drawing. Replace the bush, check that bush is properly clipsed and that nothing protrudes. Test the clearance by introducing the sensor preferably from outside. Let the paste harden.

In most cases, lower flange (2) is already welded to hull casing (1).

4/ Weld the thru-bolts (3).

5/ Grease 0-ring (13) and position it.

6/ Do not forget flat seal (7). Introduce and grease the sensor. Install sensor-flange (8). Screw the thru-bolts with (19) + (18). Do not forget circlips (15).

Attention : To introduce sensor, use grease supplied with spares. When using antifouling paint, DO NOT PAINT THE ELECTRODES, DO NOT GREASE THE

ELECTRODES. When properly positioned, the sensitive surface of the sensor protrudes at least 1 mm from external bush. The red mark on the sensor head is directed towards the fore of the vessel.

03MU002- D – Page 15



2.5 LENS PROBE WITH HULLFITTING MADE OF STAINLESS STEEL or Aluminium

A/ INSTALLATION PROCEDURE

1. Drill a 184mm hole in the hull. Do an external chamfer of 5mm (45°) for welding.

2. Position hull-fitting in the correct mounting direction.

The reference mark drawn on hull-fitting is oriented towards bow, it must be exactly parallel to the vessel axis.

The hull-fitting defines the mounting direction of the lens probe.

When the hull-fitting is welded, grind the external seam on a level with hull surface in order not to create hydraulic interferences around the probe.

3. Weld a steel pipe to back of hull-fitting.

Ø = 40mm - Thickness = Minimum 5mm

This pipe will be stopped at 50mm above maximum waterline.

4. Introduce the probe after pulling watertight cable into the pipe.

5. Brush probe bottom with watertight rubber before fixing it with its 4 screws.

Caution : DO NOT GREASE THE ELECTRODES.

When using anti-fouling paint, DO NOT PAINT THE ELECTRODES.

B/ DISMOUNTLING AND CHANGING OF SENSOR

1/ Cut off power supply of the electronic.

2/ Disconnect the watertight cable sensor from the electronic.

3/ Strongly attach the watertight cable to a rope of at least the lenght of pipe.

4/ Send a diver to unscrew the four fixation screws of sensor.

5/ Screw-up the two extraction screws in order to push out the sensor from its hullfitting.

6/ Extract the complete defective sensor with its watertight cable and the rope attached to it.

7/ Strongly attach the new sensor’s watertight cable to the rope and pull back up the cable for a new connection.

Caution : Before replacing the sensor in its hullfitting, don't forget to apply the

watertight o'ring by silicone mastic.

This equipment is DNV and GL typed approved.

3. INSTALLING THE ELECTRONIC UNIT

The BLIND ANTHEA can be flush mounted on to the bulkhead at any angle attached with 4 screws.

◊ The cover of the BLIND ANTHEA is hinged. Leave enough space on the left side for opening.

◊ After terminal connecting, pull out as many wires as possible before tightening stuffing boxes in order to limit HF radiations inside unit.

◊ If wires are hardened, they should not be hardened beyond stuffing boxes input and should be grounded to casing via stuffing boxes.

The equipment is designed for a battery power supply of 24 volts -10% +30%. Its average consumption is 200 mA.

The BLIND ANTHEA is protected against polarity reversal of the power supply ; if it does not work, reverse the wires.

The sensor cable is 16 meters long. For greater lengths (up to 150 m), use two junction boxes and two separate shielded cables (see drawing on next page).

For a 24 V power supply, the value of the fuse is 1A.

For a 220 V power supply, the value of the fuse is 125mA.

4. TESTS, ADJUSTMENTS AND CALIBRATION UPON FIRST USE

Preliminary tests

Once installation is completed, a first test must be performed before turning the power on.

Open the BLIND ANTHEA and move the Normal - Test switch (S1) to the Test position.

Turn the button clockwise to turn the device on. If nothing appears on the speed repeater, this means that the ANTHEA is not receiving any current.

Check the battery charge, then the fuse.

When working, the log is at about 80 % of the scale in Test mode.

In case a GA120 galvanometer is used, make sure that strap position corresponds to the galvanometer scale, that is :

E6

E5 E4 E3

- 2 + 16 knots

- 3 + 24 knots

0 + 32 knots

0 + 48 knots

Zero adjustment

When ship is motionless on dead calm water, speed can be above zero. You then have to correct this zero shifting.

Make sure there is no undertow.

You can easily check it by putting sensor back to front to check zero does not change.

If it does, zero can be adjusted by equalizing absolute speed values when sensor is in normal position and is back to front. Do not forget then to put sensor back in correct position (red mark towards ship bow).

4.1 LOG CALIBRATION

An E/M log measures speed and distance in relation to water. When there is no current, the distance indicated by the log is the distance in relation to the bottom or the true distance.

Several methods can be used :

a) Empirical method

Using the average of the measurements of long distances covered in comparison with the actual distances.

b) Rational method

Using the measurements of speed in covering the same base distance several times.

The device is set for the average sensitivity of its sensors in the factory.

If the first method is used, calculate the average relative error for a certain number of runs at different times and with different tide levels, but at roughly the same speed.

It is convenient to calculate these errors in percentages. The average error is calculated by taking the average of the relative errors. A large enough number of runs must be made, as in the following tables :

Runs listed by order

Error

1

- 2%

2

- 5%

3

+ 7%

4

- 6%

5

+ 2%

6

+ 1%

7

+ 4%

8

+ 3%

9

+ 1%

10

+ 3%

- 2 - 5 + 7 - 6 + 2 + 1 + 4 + 3 + 1 + 3 = + 8

The average relative error is

8 = + 0,8 %

The correction is : - 0,8 %

03MU002- D – Page 26



4.2 CALIBRATION OVER SHORT DISTANCES

It is possible to calibrate the log with precision by covering a known base distance defined by alignment on the shore, preferably following a route defined by an alignment.

Calculating true or real speed :

Clock the time needed to cover the base distance : the true or real speed Vr is :

Dr = Real distance covered

Tr = Time taken to cover the distance in seconds

The factor 3600 comes from the fact that the speed is measured in knots (miles per hour) and the time in seconds.

Calculation of the log speed

The log speed must not be read on the speed display as the measurement would not be precise enough. The average speed must be determined by clocking the time taken to complete the distance.

A second stop watch is useful, but if you only have one, the same method can be used by taking the times on the first stop watch as you go.

With a second stop watch, measure the time taken to cover the distance displayed on the distance counter. Start the stop watch as soon as the first one tenth of a mile figure changes after entering the base distance zone. Stop the stop watch when the base distance has been covered or just before reaching the end of the distance when the one tenth of a mile figure changes.

Do not change the speed or the direction of the boat until this measurement has been taken.

Log speed VI is :

V1 = D1

Let Dd and Df respectively be the distances displayed at the beginning and at the end of the trip ; the distance displayed on the log will be :

D1 = Df - Dd

If the time measured between the display of Dd and Df is T1, the average speed indicated on the log is :

03MU002- D – Page 27



Tr and T1 are not identical, since the beginning and the end of each of these timings are not identical.

If the base distance is long enough to be able to accept an approximation of a tenth of a mile, just not the indications on the distance counter upon entering and leaving the base distance zone.

The above measurements are to be taken over several runs. a) When in a zone where the current remains constant throughout the tests, the base distance zone should be covered a second time in the opposite direction, carrying out the same operations. The average of the speeds obtained is then calculated :

Vaverage b) If the current is not constant, a third run in the same direction as the first will be made, as long as the tests are made consecutively with no time out between any two test runs.

The average is calculated as follows :

Vaverage

= V1 + 2V2 + V3

V1 = speed calculated on the first run

V2 = speed calculated on the second run

V3 = speed calculated on the third run

Always try to operate at the speed given by the log, modifying the engine speed controls if necessary.

Do not perform the measurements while the tide is turning.

Having found the average real speeds and the average log speeds, a simple calculation will provide the percentage of error of the log.

The percent error is :

This error may be positive or negative.

Example : suppose that 1.1 miles are covered in a clocked time of Tr1 = 364 seconds.

03MU002- D – Page 28



The real speed will be :

1,1 x 3600

364

= 10,9 knots

The average real speed will be :

10,1 + 10,9

= 10,5 knots

2

Suppose that during the first run over the base distance, the stop watch was started when the distance counter was at : 24.1 miles, and that it was stopped when the distance counter was at : 25.4 miles, the stop watch will have run 400 seconds.

The distance read from the distance counter will be : 25.4 - 24.1 = 1.3 mile.

Calculating the indicated speed gives :

1,3 x 3600

= 11,7 knots

400

During the second run the stop watch was started when the distance counter was at 26.0

mile and stopped when the distance counter was at 27.2 miles, the stop will have run 372 seconds.

The distance read from the distance counter is : 27.2 - 26 = 1.2 miles.

The speed calculated is :

1,2 x 3600

= 11,6 knots

372

The average value of the speeds indicated is :

11,7 + 11,6

= 11,65 knots

2

Error correction :

First evaluate the error in percentage.

In the above example, the error :

= + 10 %

The correction to be made is therefore : - 10 %.

03MU002- D – Page 29



Switch "TEST" on and wait a few seconds till speed display is stabilized.

Note test value.

Calculate new test value : for example :

Test value = 18 knots

New value =

18 knots -

18 x 10

100

= 16,2 knots
