I am late to the thread. What are the hoses? The antifreeze?

I think they are the methanol and hot water lines.

You might be right on the antifreeze. They are going to pump something in (methanol?) to keep the methane from forming the ice crystals that blocked the pipe the last time and kept them from recovering the oil.
