MIAMI — Resembling giant metallic birds with their booms outstretched like wings, four super-post-Panamax cranes from China glided into the Government Cut channel Monday to prepare for the day when PortMiami welcomes some of the world’s largest ships.
The 262-foot-tall, fully assembled cranes were transported from an island off the coast of Shanghai aboard a special carrier and spent nearly three months at sea after storms around South Africa’s Cape of Good Hope slowed the journey.
The cranes are part of $2 billion in port improvements aimed at doubling cargo traffic in the next several years and making the port ready for post-Panamax ships expected to call on PortMiami when expansion of the Panama Canal is completed in mid-2015.
As the cranes appeared on the horizon Monday, PortMiami Director Bill Johnson addressed a gathering of local politicians and dignitaries at the harbor pilots’ house.
“These are four of the big ones. â¦ We are big-ship ready,” he said. “Savannah, here we come.”
The Port of Savannah, Ga., Miami’s chief rival in the Southeast and the top port in the region for containerized cargo, took delivery of four super-post-Panamax cranes in June, bringing its fleet of super-post-Panamax cranes and post-Panamax cranes to more than two dozen.
But Savannah is still awaiting final legislative approval before it can launch its own dredging project.
With the improvements, PortMiami hopes to win back some cargo that now goes to Savannah and then moves down the Florida peninsula by truck or rail to supply local markets.
The Panama Canal is maxed out and is undergoing a renovation to accommodate a new generation of post-Panamax ships that are too long, too wide and too heavy for its locks. Once those mega-ships begin traversing the canal, PortMiami wants to become a gateway port for them.
The planned dredging of PortMiami’s shipping canal to a depth of 50 to 52 feet means fully loaded post-Panamax ships will be able to call in Miami for the first time. Instead of ships loaded with 4,500 TEUs — a TEU is equivalent to a 20-foot container — PortMiami will be able to handle ships carrying 12,000 to 13,000 TEUs.
The $220 million dredging project is slated to begin next month and is expected to be completed around the same time as the canal. But the port’s crane fleet also needed an update.
The new cranes, which are as tall as a 25-story building, collectively cost $39 million. They will be capable of reaching over 22 containers, compared to 13 containers for smaller cranes, to pluck cargo from a ship and will be able to reach containers stacked 11 high on deck.
The four new cranes replace three smaller cranes that PortMiami sold to the Port of Barranquilla, Colombia, and join two other super-post Panamax cranes at the port. The super-post-Panamax designation means the cranes can unload ships that are even larger than the ones that will transit the expanded Panama Canal.
“The cranes are an important component in our growth strategy,” Johnson said.
Other parts of the port-improvement equation are a $915 million port tunnel linking PortMiami to the interstate highway system; strengthening wharves and bulkheads in anticipation of the deep dredge; and an on-port rail link between the port and the Florida East Coast Railway yard in Hialeah.
“The post-Panamax era is near at hand,” Miami-Dade County Mayor Carlos Gimenez said in a statement. “The new PortMiami cranes represent an investment that ensures that we remain competitive in the global marketplace.”
