Profession ship assistant engineer

Ship assistant engineers assist the ship chief engineer and the ship duty engineer in the operations of the ship's hull. They support the operation of the main engines, steering mechanism, electrical generation and other major subsystems. They communicate with maritime engineers about the performance of technical operations. They also ensure appropriate safety and regulatory standards compliance and are able to take on higher level positions if needed.
