Cargo ships under 5000 GT must have emergency power available for how many hours?

Cargo ships under 5000 gross tons are required to have emergency power available for 3 hours as per international regulations, such as those outlined by the International Maritime Organization (IMO). This requirement ensures that vital systems remain operational in the event of a main power failure, enhancing safety for both the crew and the vessel. This duration enables the ship to maintain essential services, including lighting, communications, and emergency systems, allowing for an orderly evacuation if necessary.

The 3-hour standard reflects a balance between operational feasibility and safety, acknowledging that during emergencies, it may take time to assess the situation, initiate corrective actions, or evacuate. This period is deemed sufficient for crews to respond effectively in an emergency while ensuring that safety measures are maintained.
