Dear CE Arif

Good day

Please advise if FWG has provision for trying out on Steam .

Idea is to try and confirm all in order prior departure China and to avoid any more surprises

Thank you & Best Regards,

Dear Sir,
Good day.

Please find the below comments from ch eng :

Please find attached work done report for Fresh water generator Evaporator plates cleaning.
Main engine both Jacket cooling FW pump stopped and In/Out valves isolated. Bypass valves isolated.
Both JCW valves to Fresh water generator isolated and leak checked found valves holding (As JCW IN valve for FWG was leaking due to overtightening).
Stopper Screw for Butterfly valve (JCW IN valve) adjusted in closed position now there is no chance of over tightening.
Fresh water generator opened and Evaporator plates removed, found solid salts formation on plates.
Cleaning of Evaporator plates carried out and boxed back. Leak tested found satisfactory.
Thanks & Best Regards,

Arif Pawney

Subject: CANGJIE// FWG Update

Dear Sir,
Good day.

PLEASE FIND  BELOW COMMENTS FROM CH ENG

Please find below observations during FWG starting, upon renewal of Distillate Pump.

  1.  FWG started and optimum vacuum reached (650~680 mmhg)
  2.  After sufficient time Distillate pump started and observed pump delivered condensate @ 2.0 Bar pressure for few minutes then delivery stopped and discharge side vacuum found drawing air.
  3.  Condensate taste was good but ppm showing was 200 (water not salty)
  4.  From evaporator sight glass we can see water on the sight glass but boil off is not sighted.
  5.  As the water in sight glass rose more than 70 %, shell temperature kept rising upto 68 Deg C.
  6.  Above phenomena was miss-understood for defective distillate pump not able to drive out the condensate from condenser. (Now noticed there is not enough condensate being produced).
  7.  Concludes Evaporator plates are dirty, although last week chemical cleaning in place of evaporator plates have carried out.
  8.  Attached Main central cooling fresh water system, Following valves 11 V, 12 V & 45 V are not holding, vessel had been provided with Spare valves.
  9.  Replacing these valves needs Black out, as we know LT & HT system both are connected to same Expansion tank.
  10. Even putting a BLANK in 45 V towards ME system side doesn’t help in isolating the HT system completely from LT as the 3-Way (14 V) valve of ME temperature controller will keep supply water to HT system with a pressure of 3.5 Bar (As Generator and LT pumps is running).
  11. Will discuss with office prior taking up Black Out Job.
                           .
