Muster Drill

All ships conduct muster drills, also known as lifeboat drills. In maritime terminology, a muster drill is an onboard exercise to ensure that all crew (as well as any passengers) know how to evacuate the vessel in the event of an emergency. International law stipulates that the Master of every ship must make sure that officers, crew and passengers are familiar with the procedure of lowering the lifeboats and evacuating the vessel, and the emergency use of the lifeboats.
