Answer:

Several sources of chlorides contamination may affect the cooling water (along with boiler water):

  • Shore-supplied water with high chloride content. Water may not be even salty, but contain some antibacterial additives, which trigger high salinity test results. Test the water in the FW system/tanks for chlorides
  • Faulty Fresh Water Generator or/and it's salinometer. In this case, salty water supplied in FW storage tanks slowly increasing its salinity. Check FWG and carry out the chlorides test of water at the outlet of FWG and in storage tanks
  • Leakages from seawater coolers. Pressure test cooler to ensure tightness
