When a ship relies on external services rather than its own plant, this status is known as what?

This tests a ship’s practice of using power from the shore instead of running its own engines or onboard generators while at berth. When a vessel is connected to shore-side electrical power, its main boilers and auxiliary generators can be shut down, a condition known as cold iron (or cold ironing). This lowers fuel use and emissions in port and reduces noise. Being docked or idle describes location or activity in port, and shore powered is a descriptive phrase for using shore power, but the established term for this powering arrangement is cold iron.
