slug catcher water removal after hydrostatic pressure

[pastyl]

We are in the final stage of the construction of a natural gas slug catcher. We are looking a way for removing the water after hydrostatic test pressure. The catcher has only two nozzles, one for drainage and one for level measurement (4"). Both nozzles are installed appr. 3m high from the catcher's main pipes (as the vessel is installed underground with it's nozzles above ground) and it is not easy to remove or rotate the vessel so as the water could be removed for the nozzles by gravity.
The catcher is vessel pipe 24" appr. 2x6m pipes and has a volume of 4000lt.

could you put a hose down one of the nozzles connected to a sump pump? ... though that probably wouldn't get 100% of the water

It's a slug catcher. If you don't have any way to get liquid out of it, you've got serious, long term problems. I bet the operators will object to shutting the pipeline down and sticking a green garden hose down into it ever slug.

Seriously, why can't you pressure it up and blow the air out the normal flow path?
