Your yacht is equipped with a generator set, operated by a diesel engine, dimensioned to satisfy the power supply requirements suitably planned in the electric balance for various navigation conditions.
The generator is located in the aft area of the engine room, placed on a stand suitable to bear its weight and vibration induced.
The generator is contained in a sound-proof box, made of removable and insulating panels in painted marine aluminium. This solution allows easy access to the engine and to the alternator for maintenance and inspection, and at the same time a remarkable reduction of noise.
The starter generator is via its own independent 12V battery.
Near the generator is located the battery switch that allows to connect or exclude the generator starter battery.
The generator is equipped with an electronic device for automatically recharging the start up battery by means of its own alternator.
The engine is cooled down, through a cupronickel heat exchanger, by sea water sucked through an independent sea water intake, located between the engines and equipped with a cut-OFF valve and an inspectable strainer.
A second heat exchanger cools down the air inside a sound-proof box and the air necessary for the alternator ventilation.
The inspectable sea inlet strainer effectively protects the cooling circuit from harmful ingress of mud, sand and algae.
The generator draws the air necessary for combustion directly from the engine room through an opening in the stand.
The exhaust is conveyed and silenced through:
Besides exhaust gases, cooling water is discharged too. Immediately after the generator exhaust manifold there is the water injection point (raiser), where the mixture of cooling water and exhaust gas is formed.
The generator exhaust, in addition to reducing noise, collects the water in the exhaust pipes when the genset engine is switched OFF, preventing it from flowing into the engine through the exhaust manifold.
The water-gas separator separates the cooling water from the flue gas and discharges them overboard; it also reduces the noise level, which is already reduced by the muffler.
The advantage of using this kind of exhaust is a considerable noise reduction, a lower grade of smoke of the exhaust and a reduction of the operating temperature.
The generator’s start up battery can be recharged by the dedicated battery charger (optional) installed on the aft bulkhead of the engine room.
The charger can only recharge the battery when the yacht’s power supply is connected to the shore.
