Immediately west of the Galván Nº 1 berth is the Polisur floating petro-chemical plant and beyond that the viaduct running out to the tanker berths (postas) Nº1 (oil tankers) and 2 (gas carriers) operated by Bahía Petróleo S.A. Piping for these berths is carried from the shore along the viaduct and the jetty to the central loading platforms. Both berths consist of 4 berthing dolphins with central loading platforms of 31×21 m and outlying berthing dolphins giving an overall berth length of 371 m each.
