Dirty job

This is a part of the cooling system, a kind of debris filter which is under water most of the time.
We clean it about every 4 hours bij scraping the seaweeeds and other stuff off with a automated trash rake cleaner, (an overhead trash rake) but apparently the seaweeds grow further at the backside of it.
So when the differential pressure over the filter is getting too high and will not come down the normal way, we have to pull out the whole rake.
This we can only do when the coolingwaterpumps have been stopped, and that can only be done when we stop the unit for a longer time (i.e. for a week).
Now is the time to do it, but it's cold....
It's not so nice to be at the pumping station, and especially doing a job like this......
It's wet, cold, everything you touch is freezing cold and so on.
But.. it has to be done because next week the unit has to be connected to the grid again.
