On this marine guide, here are all you need to know about international shore connection (ISC).
What is ISC?
ISC is a standardized flange used to connect the ship’s fire main to an external water source (shore hydrant or another vessel) in emergencies.
In the unfortunate case of a fire, a Shore Connection functions as a backup measure for firefighters on ships. In case there is a total failure of pumps on board, the ship’s own water supply is not sufficient. The ISC makes a connection to shore where another water source can take over. It provides a means to connect an external water source, typically from shore facilities or another vessel, to the ship’s fire main.

• Failure of fire pumps
• Major onboard fire
• Fire while in port
