That's not what is done on any marine plants I ever heard of, or for
that matter, any stationary ones. It would be incredibly wasteful of
fuel. Hey Rick, you following this?

No, have just got home a few minutes ago,brought a boat down from Alaska
and am now on my way to the airport to fly to Lauderdale for the
superyacht show ...

The only place water gets injected into the steam is in an attemperator
just before the evaporators. I cannot think of any single more wasteful
exercise than adding water to steam for any reason other than to cool
the steam going to an evaporator feed water heater running on live steam
rather than bleed steam.
