refelling

Refelling refers to the process of adding fuel to a vehicle or vessel. This is a common and essential activity for maintaining mobility and operational capability. For road vehicles, refelling typically occurs at a gasoline station or a diesel pump. The process involves inserting a fuel nozzle into the vehicle's fuel tank and dispensing the appropriate type and quantity of fuel. Safety precautions, such as ensuring the engine is off and avoiding sparks, are crucial during refelling.

For aircraft, refelling is a more complex operation, often conducted on the ground or in-flight. Ground refuelling involves connecting fuel hoses to the aircraft at an airport apron. In-flight refuelling, also known as aerial refuelling, allows aircraft to extend their range by receiving fuel from a tanker aircraft while airborne. This is a critical capability for military operations and long-duration flights.

Marine vessels also undergo refuelling, known as bunkering. This can take place at ports, harbours, or offshore facilities. The type of fuel used depends on the vessel's propulsion system, ranging from heavy fuel oil to marine diesel. The procedures for bunkering are standardized to ensure safety and environmental protection, as spills can have significant ecological consequences. In all contexts, refelling is a vital logistical operation that supports transportation and other activities dependent on powered vehicles and vessels.
