What is ancillary system on the ship?

An ancillary system on a ship refers to the various support systems that are not part of the main propulsion or navigation systems but are essential for the overall operation and comfort of the vessel. These systems include power generation, heating, ventilation, air conditioning (HVAC), freshwater production, waste management, and fire safety systems. They ensure the ship's functionality, safety, and the well-being of the crew and passengers. Proper maintenance and integration of these ancillary systems are crucial for efficient ship operation.
