Ballast and anti-heeling systems are used on board to ensure and achieve stability. This requirement is necessary for comfortable navigation for both crew and passengers, as well as cargo security and efficient port operation. So far, various types of technologies have been developed to achieve this. Depending on whether or not additional energy is required for stabilization, they are divided into passive and active systems. This paper provides an overview of all types and technologies used for this purpose. In order to understand the importance of the stabilizer, it is necessary to understand the oscillations of the ship, and in particular to pay attention to the rotational motion in the x-axis. Since rolling can significantly impair stability, all stabilization systems so far have just been created to dampen its operation. Depending on the stabilizer to be fitted it will depend the type of the ship. In addition, a brief overview of the history of the development of these systems and the impact of ballast on the environment is presented.
