Tembladora Transfer Station, with its deep water harbour and close proximity to Suriname, makes it a viable transshipment point. The operation starts with mooring of a shuttle ship along the western side of the 680-foot-long pier. The unloading of the shuttle vessel is performed by one travelling unloading gantry crane, equipped with an eight-cubic-yard clamshell bucket capable of an overall discharging rate of 250 metric tons of alumina per hour.

The alumina is dumped into a hopper on the unloader from where it is fed by a variable speed feeder belt (U) on a 48-inch belt conveyor (C) running north and elevating. It is then transferred by travelling tripper to any of the three conveyors (D1, D2, D3), which run over the top of the three rows of storage tanks, or a fourth conveyor (D4), which runs over the top of the bulk storage building. By this means, the alumina can be stored into any of the 15 alumina storage tanks or the building.
Under each of the three rows of tanks and under the storage building, there are concrete tunnels in which are located 54-inch-wide loadout belt conveyors (E1, E2, E3 & E4). The alumina flows by gravity to the belt through openings in the bottom of each tank and multiple openings in the floor of the building. These conveyors rise to a point above ground where they dump to a conveyor (G), which runs south to the outer end of the pier. From this conveyor, the alumina is transferred to the loading tower, which, like the unloading gantry crane, can move the length of the pier.
On the loading gantry, the alumina passes over a belt conveyor (L), a telescoping airslide and down the telescoping chute into the loading shed. The overall loading rate is approximately 750 metric tons of alumina per hour.
