I'm a bit uncertain about how far a ship running adrift should move if its speed has been reduced.
Suppose an Explorer, whose original speed is 4, takes a Fuel Systems Ruptured critical, reducing its speed to 0; then it takes an Engines Disabled critical, putting it adrift - does it start moving again now it has no engines?
What about a Hyperion with original speed 8, which is crippled and has taken an Engines Disabled critical - does it drift at speed 4 (half original speed) or speed 2 (half its crippled speed)?
The Hyperion fixes its engines, but then loses its final damage points. Now how fast does it drift?
