Shows the submarine builders sealing up the side hatch that was used for ingress in the construction, equipment loading and outfitting phase of UC3. With all the heavy machinery and engines safely installed inside the hull, now is the time to button her up tight. Afterwards the only means of access is the hatch on the topside and the one in the conning tower.
