In the final paper, the topic of the automated engine room on the ship is explained. Automation can be defined as a technology concerned with the execution of processes using programmed commands combined with automatic feedback control to ensure proper execution of instructions. The main goal of automation is to improve the efficiency, accuracy and speed of business processes, which ultimately leads to increased productivity and reduced costs. Automation on ships is becoming more and more important, and thus automation is not only a technology, but above all a culture and man is at the center of this process. Since certain processes that need to be automated on board are far from each other, it is necessary to connect them with each other through a computer network. Today, the basic components of such systems are digital computers or digital processors that process received information, calculate optimal solutions and exchange data with components of the same and/or other levels. Automatic control systems serve to manage the operation of machines and devices, i.e. processes without the direct participation of a human, i.e. an operator (eg a fully automated ship's engine room without a crew).
