 About 6 miles away from Puerto Armuelles, on Punta Burica, in the deep water of Charco Azul or in English "Blue Ditch" an ideal place was found to unload supertankers.They would then put the oil into Panamax tankers so the oil could then cross the canal and on to the U.S. refineries.Very soon after that operation started, it was decided that would be better to have a pipeline.
