And Panamanian officials are studying construction of yet another set of locks capable of accommodating still-larger ships, according to Sáenz, who commented, “We are already thinking about a fourth set of locks in years to come.”

As was the case back in 1914 when the original Panama Canal opened for business, the United States remains the No. 1 user of the waterway, with more than two-thirds of current transits beginning or ending at a U.S. port, Sáenz said. It is followed on that list by China, Chile, Mexico (propelled by Mexican exports of liquefied natural gas) and Japan. Sáenz said he anticipates that, by 2020, the number of LNG vessels going through the canal on a typical day will double to two from the current one. The greatest share of Panama Canal Authority income comes from container vessels heading from Northeast Asia to the U.S. East Coast.

The Panama Canal’s worth goes beyond facilitating passage of ships between Pacific and Atlantic oceans, according to Sáenz.

“The canal is all about reliability, connectivity and value-added services,” Sáenz.said, citing plans for adding to the container and roll-on-roll-off cargo terminals already in place at either end of the waterway, as well as an LNG terminal under study for the Pacific side, logistics park development, facilities for generation of electric power, and bunkering and pipeline installations. A third bridge across the canal is on target for completion by mid-2019.
