FWG & Hydrophore

3 lessons

Fresh water at sea and pressure at the taps: fresh-water generator operation and hydrophore pressure-water systems with their faults.

This chapter collects 3 illustrated lessons on FWG & Hydrophore as part of Auxiliary Machinery & Shipboard Systems, ordered as they are best studied. It opens with Fresh Water Generator — Vacuum Boiling, Operation & Faults, Hydrophore & Water Supply — Pressure on Demand, Reverse Osmosis (RO) Desalination Plants — Membranes, High-Pressure Pumping & Water Quality. Each lesson is written for MEO oral and written preparation: definitions first, then how the system behaves, then the checks and figures used in practice.
