On board of your yacht, two generators are installed in the engine room.
On the fuel tank flange, you can easily see the generator’s power supply, which can be cut-OFF by means of the two suction valves, on which you can handle quickly to cut-OFF the fuel lines in case of emergency in order to disconnect the generators. The connections going from the generators to the tank are for fuel flow-back.
The fuel, before being sent to the generators, is passed through the separator filters in order to retain the dirt particles and separate any water present (optional).
The exhaust gases, instead of being discharged directly overboard, are conveyed through mufflers, one on each generator placed next to them. These mufflers, by injecting water in the exhaust pipes, allow cooling down the fumes and, at the same time, reducing the noise produced by the water outflow.
To further reduce the noise, the fumes are then sent to the separators. The separators use the gravity and centrifugal forces to separate exhaust gases from cooling water.
This latter is separated and discharged directly under the water line. The exhaust gases without water are then conveyed and discharged overboard.
The sea cocks of the cooling circuit are installed on the hull with the sea water strainers, fastened to a surface close to the sea cocks valves.
Clean the sea cock strainers according to the use frequency and to the condition of the sucked waters (seaweeds, mucilages, etc..).
Before cleaning the strainers, remember to close the sea cock valves, to stop the generators and then to proceed with maintenance. Once this cleaning operation is completed, reopen the valves supplying the cooling circuit.
As to the unit supply, on each power generator set is located the control panel for the check and start/stop operations.
The generators are also equipped with battery breaker switches.
The dashboard control panel monitoring and controlling the main operating parameters (oil pressure, coolant temperature, rpm, etc..) of the generators, in order to detect any alarm situation or potential risk.
For further information on use and maintenance, please refer to the manufacturer’s manual.
