Dear sir,
I'm working as an 4th engineer onboard.
We've Alfa Laval separator TYPE-S 967 for Heavy fuel oil on our ship.
Recently we had an issue with our separator. There are number of alarms in EPC-60 like pt4 low, oil leaking from bowl, discharge feedback error etc almost instantaneously.As all this is operating water issue, on checking water side I found heavy oil in operating water hose till SV10 solenoid valve.
I don't have any idea from. Where the oil is coming from to operating water line which is located at the top of separator on inlet outlet pipe.
Requesting you to please help me in this regard, I'll be grateful to you.

Thanks and regards
