End fitting. Any one of numerous fittings used for rig conversion.
Traveling surf or surf block. An all tensioned wire rig with the highline and inhaul/outhaul lines being tended by winches on the delivery ship.
Star assembly. An all tensioned wire rig with the highline and the inhaul and outhaul lines being tended by winches in the delivery ship. It is a bell shaped assembly which is bolted to the traveling surf.
Pendant receiving station. It is being phased out of the Navy.
Span wire/highline. A 3/4 inch diameter galvanized steel wire that supports the UNREP rigs.
Probe/ROBB coupling. A device used to receive fuel. The combined quick release (ROBB) coupling and valve consist of a female and a male end. The male end, rigged on the receiving ship, is the slightly tapered tube with a flange at one end. Despite the name, the ROBB coupling does not qualify as a quick release device because uncoupling is virtually impossible when the fitting is under strain. Any strain must be taken by the riding line, and, to connect or disconnect, the ends must be lined up perfectly. To provide for emergency breakaway, a breakable spool is inserted between the receiving ship's manifold and the male end. Only U.S. ships are fitted with the ROBB coupling.
