EC20: Drain cooling system

Today: I took the opportunity to make a roundtour and check the relative humidity in a couple of systems.
The unit is in presevation and is most systems are drained and preserved by means of dried air.
This is for some systems like the generator and condensate system done by regenerative airheaters and for other systems like feedwaterpre-heaters by means of compressed dried instrument air.

The system in this picture has nothing to do with all that; it's part of the seawatercooling system and in particular this system is used to cool the drainsystem. These two 100% pumps pump seawater through a kind of vessel where hot water and steam are mixed with relatively cold seawater. After that the water is led to a pond and from there in the outlet of the cooling system
This system now is emptied too....
