Carnival Cruise Line is changing the way passengers are required to complete the emergency/safety drill, also called the muster drill. Traditionally, all cruise ship passengers would participate in a large emergency drill before the ship departs.

Instead, Carnival is allowing passengers to use its Carnival HUB App to locate where your muster station is and complete the drill in their own time (albeit before the ship departs. 

When passengers arrive at your muster station, they check in with a Carnival team member who will keep track of who has completed the exercise.
