AFAIK, the scrap minister moves ships on his own, just like the resupply and retrofit ministers do. I'm assuming the "ship movement minister" is actually the attack, defense, patrol, and exploration ministers (all the individual ministers can move ships, in fact, except for facility construction and possibly space yard ships).
We'll figure out how to set the maintenance properly the same time we figure out fleet experience.
