Without auxilary boiler how will work ship?

Without an auxiliary boiler, a ship would struggle to generate necessary steam for various systems, such as heating, propulsion, and power generation. This could lead to failures in essential functions like engine cooling, fuel oil heating, and domestic hot water supply. As a result, operational efficiency would be compromised, potentially affecting safety and overall performance. Alternative power sources or backup systems would need to be in place to compensate for the loss of auxiliary boiler functions.
