This document discusses auxiliary machinery on ships, which includes all mechanical equipment besides the main engines and boilers. It defines auxiliary machinery as machinery that serves the main engine and ship's necessities. The document then lists and describes the main functions of auxiliary machinery, such as supplying needs to the main engines/boilers, keeping the ship dry and trimmed, supplying domestic needs, applying main engine power, supplying electric power/lighting, mooring and handling cargo, and providing safety. It concludes by stating that individual engineer officers are often responsible for ensuring efficient operation of certain auxiliary machinery.
