Reference Answer
### (a) Fresh Water Hydrophore System
A Fresh Water (FW) Hydrophore System is a self-contained, automated unit designed to store and supply fresh water under constant pressure to various points of use on a vessel, such as accommodation, galley, and laundry facilities. It eliminates the need for a high-level gravity tank, thereby saving space, reducing structural weight, and improving ship stability.
#### System Components
1. **FW Storage Tanks:** Tanks where potable water, produced by an evaporator or taken from shore, is stored.
