How the fuel oil system works on board the ship?
– Fuel oil transfer system – This system receives and stores fuel and delivers it to settling tanks. Fuel oils are loaded through deck fill connections that have sample connections provided to permit the fuel to be sampled as it is taken aboard. HFO is loaded in storage tanks fitted with heating coils.
What is a fuel oil system?
The fuel oil service system is designed to deliver fuel oil to the boilers at temperatures and pressures suitable for satisfactory combustion. The system basically consists of settling tanks, suction and discharge strainers, pumps, heating coils, seven valves to properly meter fuel and other assorted hardware.
What are the types of fuel oil the we use onboard ship?
From the point of view of marine fuels, the first types to be of use are marine gas oil (MGO) and marine diesel oil (MDO). These are the distillate fuels and used mostly in high and medium speed engines and gensets.
How do you test fuel onboard ship?
The onboard lube oil tests are carried out by taking samples from the sampling point, which should be located after the system, with the system in running condition. Before taking the sample, oil must be drained so that stagnant oil in the sampling point is removed.
What is the function of the fuel system in a ship?
The function of the fuel injection system is to provide the right amount of fuel at the right moment and in a suitable condition for the combustion process. There must therefore be some form of measured fuel supply, a means of timing the delivery and the atomisation of the fuel.
How does a fuel oil system work?
When your oil burner is engaged, heating oil travels from the tank to the burner by way of a pump where it becomes a fine mist mixed with air. The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber.
What is the difference between 180 CST and 380 CST fuel oil?
“The 180 CST is supported by strong demand from power sector, but the 380 CST HSFO market is not weak. The strong viscosity spread is due to strong 180 CST,” a Singapore-based trader said.
What is the difference between MGO and MDO?
Marine gas oil (bunker fuel or bunker oil) is any type of diesel which is used in seagoing vessels. The switchover to lighter types like Marine Diesel Oil (MDO) or Marine Gas Oil (MGO) requires monitoring and some modifications to the burner and fuel systems.
What are the importance of testing of fuel oil onboard?
Why is marine fuel oil testing important? Regular fuel testing is vital as it ensures that you know that the fuel oil you’re bunkering and use is fit for purpose. There are host of problems that can occur with your fuel, both from the traditional heavy fuel oil to the more modern low sulphur fuels.
What is the difference between heavy fuel oil and diesel?
Unlike heavy fuel oil (HFO), marine diesel oil does not have to be heated during storage. Marine diesel oil is sometimes also used synonymously with the term “intermediate fuel oil” (IFO). In the strict sense, the term marine diesel oil mainly refers to blends with a very small proportion of heavy fuel oil.
What is the difference between fuel oil and diesel oil?
2 diesel fuel oil are almost the same thing (diesel is different in that it also has a cetane number limit which describes the ignition quality of the fuel). Distillate fuel oils are distilled from crude oil. Gas oil refers to the process of distillation. It is the same thing as heating oil.
How does the fuel oil system on a ship work?
The mixing tank is used to collect recirculated oil and also acts as a buffer or reserve tank as it will supply fuel when the daily service tank is empty. Fig : Fuel oil system for cargo ships The system includes various safety devices such as low-level alarms and remotely operated tank outlet valves which can be closed in the event of a fire.
How is fuel oil transferred to service tanks?
– Fuel oil treatment system – From the settling tanks fuel oil is transferred to the service tanks via FO treatment system. For cleaning of heavy fuel oils (HFO) the two stage process is commonly used.
How is fuel oil cleaned in a HFO system?
For cleaning of heavy fuel oils (HFO) the two stage process is commonly used. The fuel is heated in a settling tank to about 50-60°C and then is drawn out by the purifier inlet pump. The inlet pump delivers the fuel to a thermostaticallycontrolled heater which raises the fuel temperature to about 80°C,…
How are settling tanks used in fuel oil treatment?
Settling tanks are used to permit gross water and solids to settle on the bottom. – Fuel oil treatment system – From the settling tanks fuel oil is transferred to the service tanks via FO treatment system. For cleaning of heavy fuel oils (HFO) the two stage process is commonly used.
