The lower level of the engine room contains many of the pumps, valves, and other plumbing which services the Mather's boilers, ballast tanks, lube oil systems, fire fighting, potable water system, and sewage system as well as air compressors.
Visible in the above picture on the left hand side is the number 2 fire/deck pump and compressed air tanks, on the right hand side part of the surface condenser.
Moving forward on the port side are the air compressors, high condenser discharge, and bilge pump. This side of the pump desk has far more plumbing that the starboard side.
A little further forward takes us to a thicket of steam lines.
Looking across the centerline of the vessel from port to starboard just forward of the turbine (on the right.) The green-caped machine in the forground is the main circulating pump, then the condensor well. White-wall on the left is the main boiler feedwater tank.
At the forward end of the port side are the port ballast and stripper pumps.
