Bowser (tanker)

[2] The term also describes refuelling boats that supply seaplanes, army fuel tankers used for combat resupply, and vehicles that fill heavy construction equipment such as hydraulic excavators and bulldozers.

As such, it is a method of mutual distribution, improving fuel access for customers while reducing the main costs of each distributor.

Being a commercial service, it normally applies to DERV (Diesel Engined Road Vehicle ]) rather than petrol (gasoline), but can also include new energy solutions, for example, a Hydrogen Bowser which can be used to refuel gaseous hydrogen to mobile plant and machinery.

[4] At the former nuclear research facility at Dounreay in the far north of Scotland, the word bowser is used to describe various moveable (but not wheeled) vessels that contain alkali metals (sodium or NaK), protected from oxidation by an inert gas.

The word may also have been in use at the Atomic Energy Authority's (now UKAEA's) southern sites.
