Chief engineer
A chief engineer, commonly referred to as "ChEng" or "Chief", is the most senior engine officer of an engine department on a ship, typically a merchant ship, and holds overall leadership and the responsibility of that department. As a person who holds one of the most senior roles on the ship, they must have excellent communication and leadership skills. They will be expected to regularly work alongside other crew members and external consultants, and most importantly, provide guidance to their team. To be a chief engineer, an engineer must attain a chief engineer's license appropriate to the  tonnage, power rating, and type of ship that they are employed on. A chief engineer is ultimately responsible for all operations and maintenance that has to do with any and all engineering equipment throughout the entire ship, and supervises all other engineering officer and engine ratings within the department.
