What is Piping System in the Engine Room (Motor Ship)?

Piping system in the engine room is quite complicated. It is necessary to all
personnel working in the engine room to familiarize them actually, to understand and
locate the arrangement of all equipments connected in a piping system in order to
operate safely. To clearly identify the kind of fluid flowing in the system, color
markings are stenciled in the engine room piping’s. Piping symbol lists are provided
in the finished plan/maker’s instruction manuals. Actual sample of piping system is
incorporated in this handbook and explained in detailed manner to use as guide
during operation. Some of the components may vary depending on the design
requirements of the machineries.
