A cargo of LNG loaded in Australia is en route to South America in an unusual trade that has not been seen for the last four years.

Ship tracking experts said the 173,400-cbm Sevilla Knutsen (built 2010) left the Queensland Curtis LNG plant on 26 July.

The ship, which is on charter to energy major Shell, has arrived off the coast of Chile and is expected to dock at the Quintero LNG receiving terminal on 15 August.
