Joining them soon, asked them this question at the interview with a view on how long it would be to command, their reply was:
"When you get 3000 (factored) hrs you are assessed for command in your OPC/LPC and if successful, put in the pool for command for the next available slot. At the moment the wait in the pool is not too long as they need Captains."
"They don't need a seniority list as they only have one type, so cross fleet movements and promotions are not factors"
