Reduced feed rate
New HJ SIP valves were installed during overhaul and the piston rings were changed. After a running period of 3,100 hours the feedrate was lowered to 0,62 g/kWh with a recommendation of reducing to as low as 0,55 g/kWh.
This corresponds to yearly saving in lube oil of 156L/24hrs.
or $100,000 in yearly savings for the vessel (price est. $2,1/L).
Further more the iron value measured in the lube oil 3 months after the overhaul was reduced by 25% compared to before changing the rings.
Unit 2 at 22,272 running hrs (3,166 running hrs. with HJ SIP valves)
