The fuel tank is built with fibreglass according to ISO 10088 standards and is located at bow in the engine room under the flooring of the VIP’s cabins.
The tank is filled through two filler necks, located inside two suitable peaks placed along the side walk-arounds of the yacht.
The fuel level is detected by a sensor and is visible by means of the control panel, located in the main station.
It is possible to monitor the level in the tank also by means of a visual gauge, attached directly on the fuel tank flange. This gauge can be actuated by means of a ball valve and a push-button valve, and it must be activated to check whether the transmitted value corresponds to the real level of fuel inside the tank.
Your yacht is equipped with a fuel treatment system.
It is a good rule, before each navigation, to check again the fuel level also by means of the visual check installed on the tank flange.
The level indicated without operating the valve refers to the last check.
While checking for consumption and distances, it is a good rule to always keep plenty of margin, so as to be able to face bad weather conditions or other possible unexpected events.
The fuel is sucked directly from the tank and is sent to the distribution manifold, which supplies the engines and the generators.
The fuel sucked, before reaching the uses, flows through the water/fuel separator filters holding impurities and separating possible water in the fuel.
During boarding, the fuel flow produces a lot of foam; if this comes out, you might think the tank is full. Therefore, it is good to wait for a few minutes and then top up, in order to be sure that the tank has been filled correctly.
The particular geometric shape of the tank allows the decantation of impurities in the fuel tank.
It is appropriate to fill the tank some hours before setting up for navigation, in this way the impurities in the fuel will settle down and water will decant as they are both heavier than fuel.
The tank is drained through a manually operated valve located on the consumer flange.
The draining should never be conveyed to the bilge. If accidentally the draining is conveyed to the bilge, disconnect the bilge pumps and clean accurately.
To avoid fuel fumes, the tank has been equipped with two vent manifolds and a flame trap.
The activation of the fire-fighting system implies the closure of the fuel cut-OFF valves.
The sensor reading can be distorted by the temperature, because the specific weight of fuel varies according to this last parameter and to the yacht trim. Therefore before setting-up for navigation, always refer to the visual level in the engine room.
Every marina has dedicated toxic waste disposal areas. It is recommended not to scatter waste that can contaminate the environment (such as used oil, fuel, oily liquids, batteries, etc..).
Prior to perform any job in the engine room, disconnect the bilge pumps switches, to prevent accidental fuel, lubricant or other liquid leaks and therefore the pollution of the yacht surrounding waters.
Because of the high temperature in the engine room, oil or fuel leaks can evaporate and create a serious risk of fire.
Fuel leak can cause a fire to break. Check regularly the integrity of the system.
The bilges of the engine room must always be kept clean, so that fuel or oil leaks or penetrations from the engines or the generators can be easily noticed. If leaks are noticed, it is necessary to stop the engines and to let them cool and only afterward, if possible, repair the leak.
Finally clean the bilges.
It is forbidden to discharge bilge water mixed with oil or diesel fuel into the sea, because this can cause of serious pollution. Check periodically the level of possible oily waters contained into the collecting tanks under the engines, should their level be close to bilge over flooding, disconnect the magneto-thermals switches of the bilge automatic pump system, to avoid accidental spills, until the tanks have been completely drained in accordance with the environmental legislation. During the maintenance operation in the engine room, it is compulsory to disconnect the magneto-thermals of the bilge pumps automatic suction system, avoiding in this way accidental spills.
EXPLOSION/FIRE DANGER
EXPLOSION/FIRE/POLLUTION DANGER
Fuel system connections that are too loose or too tight can leak, resulting in fuel loss, environmental pollution and explosion/fire danger.
Be careful not to accidentally damaging the system fuel pipes.
Periodically carry out the verification of all the fuel pipes.
