Drain any condensate water from the oil-lubricated main bearings by
means of through-flushing or by draining through the ports in the bearing
pedestals. The drain ports are marked by a sign "Oil drainage at
maintenance" attached to the bearing pedestal. For through-flushing,
use an anti-corrosive agent that removes water and humidity but does
not cause any harm when mixed with the lubrication oil, e.g. Mobilarma
MT (Mobil).
