What does an international shore connection (ISC) provide?

An international shore connection (ISC) is specifically designed to provide firefighting water to a vessel's fire main. This connection allows firefighters onshore to quickly and efficiently supply water directly to a ship's fire suppression system in the event of a fire. The primary purpose of the ISC is to ensure that vessels can access a reliable source of water for firefighting, especially when docked or in port, thereby enhancing the overall safety of marine operations.

The connection is standardized internationally to ensure compatibility between various vessels and shore facilities globally, promoting effective response in fire emergencies. Its design typically includes specific adapters and fittings to accommodate different fire main systems used by ships, ensuring an efficient transfer of water.

Other options do not align with the primary function of the ISC. It does not provide electrical supply, emergency evacuation routes, or fuel supply, as those requirements are managed by different systems and protocols on vessels and at port facilities.
