The water in FW tank suddenly became salty. What may be the cause? There is no interconnection between FW and SW systems.
- Salt water coul enter from the outside through penetrations in hull or deck, depending on your ship arrangement. Drain the water and conduct a tank inspection.
- check your Fresh Water Generator and salinometer. If salinometer is faulty or disconnected it can not prevent contamination of FW tank with a salty water in case of FWG failure.
