General rules and laws concerning safety and accident prevention must always
be observed.
Introduction
The thrust given by the bow thruster will vary from vessel to vessel depending on the effect of the wind, the water displacement and the shape of the underwater hull.
The nominal thrust quoted can only be achieved under the most favourable conditions. Therefore, the following factors are to be observed:
- Flow and pressure of the pump must be attuned to the hydraulic motor.
- The actual method of connecting the thrust tunnel to the ship’s hull is of utmost importance for the best possible performance. See paragraph ‘installation instructions’.
- Only when absolutely necessary (e.g. when sailing frequently in muddy or polluted waters) grids may be installed to the tunnel openings.
- In case such grid bars are being fitted, please observe closely the recommendations made in paragraph ‘installation instructions’.
Compliance with the recommendations that follow hereafter, will result in a longer life and better performance of the bow thruster:
-
Never run the bow thruster continuously for a long period of time.
With a view to the internally generated heat. -
Check during sailing that the maximum temperature of the hydraulic oil doesn’t exceed a temperature of 100 degrees C.
-
All of the specified maintenance should be carried out regularly.
Use
General
-
The bow thruster can only be used if the main engine, which drives the hydraulic pump, is in operation.
-
The thrust of the bow thruster depends on:
-
the number of revolutions of the main motor
-
the number of pieces of hydraulic equipment switched on (for instance simultaneous use of both bow thruster and stern thruster)
-
Depending on the type of load-sensing-valve used, the bow
thruster must be operated using the appropriate control panel: -
1-step load-sensing-valve:
3-position lever switch: BPJE2 or BPJDE2, or selector switch: BPSE2 -
2-step load-sensing-valve: 5-position lever switch: BPJ5 or BPJSTH5 or BPJ5D
Caution
If 2 control panels are installed never operate the bow thruster from both
panels simultaneously
3-position lever switch, or selector switch
- Switch the main switch on.
- Switch the panel on.
- The valve is operated by means of the lever switch
- The lever will not stay in positions ‘L’ and ‘R’. The lever will always jump back to the middle position ‘C’.
- After using the bow thruster switch the panel off.
- Switch the main switch off when leaving the ship
5-position lever switch
- Switch the main switch on.
- Switch the panel on.
- The valve is operated by means of the lever switch
- In positions ‘1L’ and ‘1R’ the bow thruster works at approximately half the thrust (depending on the load-sensing pressure set).
- In positions ‘2L’ and ‘2R’ the bow thruster works at full thrust.
- The lever will not stay in positions ‘2L’ and ‘2R’. The lever will always jump back to position ‘1L’ or ‘1R’.
- After using the bow thruster switch the panel off.
- Switch the main switch off when leaving the ship
Installation instructions
These installation instructions give guidelines for fitting the VETUS hydraulic bow thrusters ‘BOW55HMD’, ‘BOW95HMD’, ‘BOW160HMD’, ‘BOW230HMD’ , ‘BOW310HM’D, ‘BOWH410’ and ‘BOWH550’.
This installation instruction explains only that part of the installation that differs from the installation instruction going with the bow thrusters ‘55 kgf’ model ‘55 kgf’ (‘BOW55HMD’), ‘95 kgf’ (‘BOW95HMD’), ‘160 kgf’ (‘BOW160HMD’), ‘230 kgf’ (‘BOW230HMD’), ‘310 kgf’ (‘BOW310HMD’), ‘410 kgf’ (‘BOWH410’) and ‘550 kgf’ (‘BOWH550’)
So consult for the installation of the entire hydraulic bow thruster also the relevant bow thruster instruction.
Hydraulic motor
The room where the hydraulic motor of the bow thruster is installed should be dry and well ventilated.
The hydraulic motor can be installed in various positions.
The hydraulic motor must be positioned in such a way that it is always well
clear from the maximum bilge water level.
Final assembly
- Grease the threads of the fastenings bolts with ‘outboard gear grease’ and install the hydraulic motor to the intermediate flange.
Hydraulic installation
Consult the installation manual ‘Installation manual Hydraulic installation’
Electrical installation
Consult the installation manual ‘Installation manual Electrical installation’
- For a first check, turn the propeller by hand, it should turn easily, whilst being connected to the output spindle of the hydraulic motor
*) A suitable grease is VETUS ‘Shipping Grease’, Art. code: VSG.
Trouble shooting
Hydraulic motor rotates (too) slowly.
- Speed of the hydraulic pump is (too) low.
Hydraulic motor does not rotate at all.
- Check whether the main switch is in position ‘ON’.
- Check whether the control circuit fuse is blown. Control circuit is shortened, check wiring.
- Transmission of the hydraulic pump is faulty
The hydraulic system looses oil.
- Check all tubing and connections for possible leakage.
