IMO,

it may eventually lead to corrosion of seal rings.

If that were to happen then IMO the rings are made of the wrong stuff.

There should be a labyrinth seal between the seal steam side and the lube oil side that minimizes the crossing of water into the lube oil. Water laden lube oil is a poor lubricant and too much will lead to early bearing failure. Hire a competent turbine engineer ASAP.

Please put all your test questions into a single thread so that they may be disposed of all at once.
