What about the partial oil burning vessels under construction?  I can retrograde vessels with steam turbines under construction down to logical year of build for their engines.

Rohan's ships are a bit more advanced, in some areas, behind in others.  They are better than historical in many cases, but behind the Dreadnoughts still in areas (Arcadias not withstanding, but those are heavily modified French ships), actual Rohan designs are still between predreadnought and South Carolina.

Partially oil burning vessels will fall into two categories
a/ bunkerage with 10% oil to enhance coal fires
b/ 10 to 100% bunkerage - this requires the development of the relevant technology.
