Thanks Stevefury, I think I understand now. The relief line looks like a way to send the auxiliary returns directly to the main condensers instead of the direct contact heater?Hi Rancor.
The starboard side is the silent blow-off valve. There are two connections on the port side facing forward. One is the relief and the other is the turbine start.
Many of these connections were speculative as we (I) don't have these parts of the piping details for this area of the room. I had followed the suggestions closely as possible which were made by more experienced folks than myself and this is how I have them arranged.

Port side relief (Large upper valve) to a main exhaust return and the turbine start connected to a regulated steam supply:

Here is a photo of the area on Britannic:

And the turbine start allows the turbine to be turned over without the main engines running? Introducing high pressure steam directly into the exhausts of the main engines?
