[READ THIS FIRST!!]

IMPORTANT NOTICE ON TIDE MEASUREMENTS

(In nav-aided mode, tide accuracy depends heavily on gyro accuracy.)

SETTING SHIP’S HEADING

The CI-35/35H has the nav-aided mode to measure absolute tides even in deep waters where ground tracking is unattainable. To achieve reliable measurements, however, you must supply accurate heading (gyro) information and ship’s position (or speed/course) data to the CI-35/35H.

If you are going to use nav-aided mode, set the reading of the AD converter (gyro interface) exactly with that of master gyrocompass.

Procedure

1. Confirm that the gyrocompass has settled and all the necessary compensations (latitude compensation, weather compensation, etc.) are made correctly.

2. Manipulate the AD converter to obtain the same reading as you read on the master gyrocompass. (Do not make adjustment while the ship is turning.)

Master

(Gyro Interface)

If the gyro reading is accurate enough, the CI-35/35H should provide accurate tide information. If the gyro data contains some error, however, you may see the following symptoms.

¡ Set/drift information on nav-aided mode differs from that on ground-tracking mode.

¡ Tide/tide differential information on nav-aided mode differs from that on ground-tracking mode.

CALIBRATING COURSE OFFSET (Automatic)

A. When ground-tracking is attainable:

1. Make sure the navaid (GPS) is working correctly and accurately.

2. On CI-35/35H, select ground tracking mode. (Press the TRACKING MODE key to see the

“GT” mode indication on the display.)

3. In Menu 4, set ‘CRS CAL MODE’ to “GT”.

4. Run your boat at a speed about 10 kts, keeping the same direction. To minimize the effect of gyro speed error, it is desirable to run along parallels (i.e., eastward or westward).

5. In Menu 4, place the cursor on “START” (‘CRS CAL EXEC’) and then press the EVENT key. As soon as you press the EVENT, “0.0” should appear in reverse text at the upper-right part of the display. After 2 mile-run, the display will show the course calibration angle

(result of calculation) in normal text.

4. Run your boat at a speed about 10 kts, keeping the same direction. To minimize the effect of gyro speed error, it is desirable to run along parallels (i.e., eastward or westward).

5. In Menu 4, place the cursor on “START” (‘CRS CAL EXEC’) and then press the EVENT key. As soon as you press the EVENT, “0.0” should appear in reverse text at the upper-right part of the display.

6. When the boat has run for 5 minutes, turn your heading almost 180˚ and steer back to the start point. After 10 minute-run, the display will show the course calibration angle (result of calculation) in normal text.

WHY IS GYRO DATA IMPORTANT IN NAV-AIDED MODE?

If you consider the difference of tide vector calculations is ground-tracking mode and in nav-aided mode, you will realize how important the gyro (heading) information is.

Tide Calculation in Ground-Tracking Mode

In ground-tracking mode, the CI-35/35H derives tide information from the following data.

(1) Ship’s speed/course based on ground

(ground speed)

(2) Ship’s speed/course based on target layer

(water speed)

(3) Bearing of ship’s bow

(Heading by gyro)

θ

G

: True bearing of ship’s bow (ref. north)

: Gyro reading

: Direction of ground speed (ref. bow)

W

: Direction of water speed (ref. bow)

Both ground speed (1) and water speed (2) are sensed by the common transducers mounted on the hull. Thus, they are the speed vectors with respect to the ship’s bow. No matter what the true bearing of ship’s heading be, the relative angle of these two vectors does not change. The tide vector is simply given as the difference of these two speed vectors.

Tide Calculation in Nav-Aided Mode

In nav-aided mode, the CI-35/35H derives tide information from the following data.

(1) Ship’s speed/course sensed by the external navigator (GPS)

(nav speed = pseudo ground speed)

(2) Ship’s speed/course based on target layer

(water speed)

(3) Bearing of ship’s bow

(Heading by gyro)

: True bearing of ship’s bow (ref. north)

: True bearing of nav speed (ref. north)

: Direction of water speed (ref. bow)

Here, nav speed (1) is the ship’s speed vector sensed by the external navigator, and the moving direction is expressed with respect to true north.

While the water speed (2) is the ship’s speed vector measured by CI-35/35H using the Doppler shifts against the measuring layer, and accordingly its direction is expressed with respect to the ship’s bow.

As the directional reference of these two vectors are different (north vs ship’s bow), we can not simply calculate the difference of vectors to obtain the tide vector in question.

Tide Vector

So the direction of water speed vector (2) is converted to true bearing (north reference) by using the gyro data, and then the tide vector is calculated.

Without gyro error

If the gyro data contains some error, the true bearing of the water speed vector changes (rotates) accordingly. While the bearing of the nav speed vector does not change with the gyro error. (The relative angle of these two changes.)

In other words the tide vector, given as a difference of these two speed vectors, changes in size

You may now realize that the gyro data in nav-aided mode is very important and it has to be accurate enough for reliable tide data.

To obtain dependable tide/tide differential data, it is desirable to reduce the gyro error below 1 degree.

Tide Vector

With gyro error

Relative angle of water speed vector and nav speed vector changes with gyro error.

Accordingly, the size (speed) and direction of tide vector change.

Note: The depth must be at least 40 m in order to calculate tide.

CHAPTER 1. GENERAL

1. FEATURES

¡ The functions of CI-35 and CI-35H are same. CI-35H is type approved by MOT (Ministory of

Transportation).

¡ Even in deep waters where ground (bottom) reference is not available acoustically, the CI-35/

35H can provide absolute movements of measuring layers by receiving position (or speed) data from GPS navigator and heading data from gyro compass. It may be used on deep sea fishing boats or on ocean research vessels.

¡ The CI-35/35H consists of three major units; display unit; transceiver unit and hull unit (transducer), each compact enough to permit installation even on a small boat.

¡ Triple-beam system for automatic error compensation against pitching and rolling of vessel.

Single-mold transducer makes installation easy while maintaining mechanical beaming accuracy.

¡ Sounding frequency of 130 kHz provides high interference immunity from other acoustic equipments. Intelligent digital signal processing technique adds tracking stability and measuring accuracy.

¡ Echo level display always on screen. Permits constant monitoring of signal conditions of three sounding beams.

¡ Tide effect display plots movements of tides beneath the vessel’s course track. Helpful in estimating three-dimensional deformation of cast net.

¡ Tide history display presents change of tide over last 24 sample points (24 hours maximum)

¡ Raw data output port provided for collecting and analyzing current data on a separate computer.

Note:

When transmitting with the external transmission pulse (KP) taken from an external device

(echosounder, sonar, etc.), the repetition rate of the KP should be more than 500 ms. The repetition rate may become shorter than 500 ms when the range setting on the external device is less than 100 m. Therefore, set the range on the external device to more than 100 m.

1-1

2. PRINCIPLE OF MEASUREMENT

When a moving vessel emits an acoustical pulse into the water at an angle, a portion of emitted energy is reflected from the seabed and other microscopic objects in the sound path, such as plankton or air bubbles. The frequency of the received signal is shifted from the transmitted frequency in proportion to relative velocity between the vessel and underwater reflecting objects. This is called

Doppler Effect.

The CI-35/35H calculates and displays movements of ship and currents at specific depths by measuring Doppler shifts obtained from three separate directions.

Planktonic layer

Seabed

Frequency of reflected signal is shifted in proportion to relative speed between the vessel and reflecting objects.

Ship’s Speed

(Here, speed is a vector value including velocity and direction.)

Depending on the base of measurement, ship’s speed is expressed in two ways:

Ground tracking speed:

Ship’s speed and course relative to seabed (fixed base)

(Absolute speed)

Water tracking speed:

Ship’s speed and course relative to water layer just below the

(Relative speed) vessel (floating base)

Assume that the ship and layer A are moving in the same direction, and ship’s speeds based on ground (Vg) and on layer A (Vwa) are measured as;

Vg = 10 kt (Ship’s speed based on ground)

Vwa = 7 kt (Ship’s speed based on layer A).

Speed of layer A based on ground (C1) can be calculated as follows:

C1 = Vg - Vwa

= 10 - 7

= 3 (kt)

Nav-Tide

(Absolute tide)

Absolute tide can be measured in the nav-aided mode.

Nav-aided ship’s speed (Vn) is equivalent to ship’s ground tracking speed in the ideal conditions.

That is, the nav-tide can be calculated by simply replacing Vg with Vn in the above equation.

Assuming that the ship, layer A and layer B are moving in the same direction, and ship’s speeds based on layer A (Vwa) and on layer B (Vwb) are measured as;

Vwa = 8 kt (Ship’s speed based on layer A)

Vwb = 5 kt (Ship’s speed based on layer B)

Tide differential calculations in ground tracking mode

As an absolute ship’s speed (Vg) is available in the ground tracking mode, tide speeds of layer A

(C1) and layer B (C2) based on ground are calculated as follows:

C1 = Vg - Vwa (Speed of layer A based on ground)

C2 = Vg - Vwb (Speed of layer B based on ground)

Thus, the tide differential (Cd) between layer A and layer B is;

Cd = C2 - C1

= (Vg - Vwb) - (Vg - Vwa)

= Vwa - Vwb

= 8 - 5

= 3 (kt)

In the water tracking mode, watermass just below the transducer (near-surface layer) is taken as the base of all measurements (virtual ground). Therefore, the ship and tide speeds in the water tracking mode are not absolute but relative to this near-surface layer.

Vw = 9 kt (Ship’s speed based on near-surface layer)

Vwa = 8 kt (Ship’s speed based on layer A)

Vwb = 5 kt (Ship’s speed based on layer B)

Tide differential calculations in water tracking mode

Tide speeds of layer A (C1) and layer B (C2) relative to near-surface layer (Vw) are calculated as follows:

D1 = Vw - Vwa (Speed of layer A based on near-surface layer)

D2 = Vw - Vwb (Speed of layer B based on near-surface layer)

The tide differential (Dd) between layers A and layer B is; or

Dd = D2 - D1

= (Vw - Vwb) - (Vw - Vwa)

= Vwa - Vwb

= 8 - 5

= 3 (kt)

Dd = D1 - D2

= (Vw - Vwa) - (Vw - Vwb)

If you compare the results of calculations on this page with the ones on preceding pages, you will find the tide differential of two layers is identical irrespective of tracking mode.

TIDE SPEED/DIRECTION

Display (text)

Tide speeds/directions of three layers are displayed below the ship’s speed/course.

Depending on the tracking mode in use, the meaning of speed/direction changes as follows

`

In the ground tracking mode, speed/direction values represent movement of the layer relative to ground. [Ground-based tide = Absolute tide]

`

In the water tracking mode, speed/direction values represent movement of the layer relative to near-surface water. Strictly speaking, they do not represent tide but tide differential. [Surface-based tide = Relative tide]

`

In the nav-aided mode, speed/direction values represent movement of the layer relative to pseudo ground. [Ground-based tide = Absolute tide]

(Note that accurate ship’s speed/course and heading information must be applied to CI-35/

35H to obtain reliable tide data.)

To set measuring depth of tide;

Depth value of the selected layer appears is green.

Press the same key again when desired depth is set. The depth value will return to white.

The CI-35/35H can hold last 24 tide samples collected at a time interval of 15 sec, 1 min, 5 min, 10 min, 30 min or 1 hour. The tide history presents variation of these tide information with a string of round marks. That is, distance from the graphic center to a mark represents tide speed at the sample time, and the direction from the center to a mark represents tide direction.

The figure below can be interpreted that the tide has changed from SW to NE (opposite) direction.

`

To call the tide history display, press the HISTORY key. The tide history of layers activated in

MENU 1 - “LAYER n” are displayed. (The figure below shows history of only one layer.)

TIDE EFFECT

Display

The tide effect display is useful for estimating three-dimensional deformation of cast net by the effect of tides at different depths. Notice that display merely shows movements of layers; it does not show true net shape in the water.

Assume that you put drifting marks (virtual buoys) on the net at each layer below the vessel at an interval of six seconds.

Virtual buoys

Layer 1 (YEL)

Layer 2 (PPL)

Layer 3 (L-BLU)

As the marks move with the tides keeping the same speeds and directions, a series of marks makes a brief section shape of the net at the layer.

In practice, a net does not sink immediately, because of various tensions and stresses placed on it. Thus, use the tide effect information only as a reference.

If all layers are moving at the same speed and direction, buoy tracks of all layers should coincide.

If the self check reveals equipment fault, shown by the error code, report the results to the service technician when calling for service. (The user should not attempt further check inside the equipment.)

WARNING

Do not open the cover of the equipment.

This equipment uses high voltage electricity which can shock, burn, or cause death.

Only qualified personnel should work inside the equipment.

Procedure

10. NAV-AIDED TIDE MEASUREMENT

Even where ground tracking is unattainable, absolute tide movements (tide on ground) can be calculated by applying accurate position and heading data to CI-35/35H. This function may be extremely useful for deep sea purse seining or oceanographic survey.

Note: 1. Depths are measured below transducer surface.

2. The CI-35/35H uses an acoustic wave for speed measurements. Aeration due

to rapid accelera tion/deceleration, heavy engine/propeller vibration or interference from other sounding equipments can degrade performance of this equipment.

3. Tide speed measuremants are made by detecting echoes from underwater microscopic objects like plankton. If density of microscopic objects is too high or too low, depending on season or operating areas,

CI-35/35H may not provide normal measuring performance.
