What is the purpose of a bilge alarm?

The purpose of a bilge alarm is to alert the crew of abnormal water levels in the bilge, which is the lowest part of a ship where water typically collects. Monitoring water levels is crucial in maintaining the vessel's safety and stability. An elevated water level in the bilge can indicate potential flooding, leakage, or malfunctioning of pumps, which could lead to serious safety hazards. By triggering an alarm when water reaches a certain level, the crew is notified in time to take appropriate action, such as identifying the source of the water intrusion and managing the situation before it escalates. This proactive approach is essential in preventing damage and ensuring the integrity of the vessel during operations.
