This is the second steam release pipe from the steam engine we found. The first one was found last year in the sand off the ship's portside. The steam release pipe is often called a "spittoon" because it is similar to one in shape. It was connected to the steam chest on the engine and ran to the top of the hurricane deck roof. Its function was to release excess steam pressure. Image courtesy NOAA/NURC-UConn/The Science Channel.
