Early North Sea oil accelerates Royal Navy conversion

What changes if a large North Sea oil field is discovered in Scotland in 1904?

The Royal Navy moves to oil firing earlier, probably by the Orion generation, while secure domestic coal and petroleum strengthen Britain's strategic fuel position.

Domestic oil would transform the debate over relying on imported fuel for capital ships. The discovery arrives too late to redesign the earliest dreadnought immediately, but the Orion generation and later ships could adopt oil firing much sooner. Britain would then combine abundant Welsh coal with secure domestic petroleum instead of treating oil endurance as a foreign-supply vulnerability. That energy position creates consequences far beyond one ship class because competitors must plan against a more efficient and logistically secure Royal Navy.
