This thesis provides a detailed description of the configuration and operation of marine pumps, along with an overview of their historical development, with a special emphasis on the improvements and automation of systems utilizing marine pumps. The study also addresses the classification of various automation systems on board, including key components such as alarm and safety systems, which are essential for the safe and efficient operation of the vessel, where the focus will be on automatic regulation and the PID controller. The main focus of the paper is on the automation of marine pump operations within a given system, offering a detailed description of different types of pumps, their characteristics, and specific applications in various maritime operations. Through system analysis, the importance of automation in modern maritime systems is highlighted, not only for increasing efficiency and safety but also for reducing the need for human intervention, thereby optimizing processes and contributing to the reduction of operational costs on board.
