Going Into Depth
Friday, December 16th, 2011I chatted with a friend in the shipping business about the Panama Canal expansion. More than $5 billion is being spent to expand the canal’s locks to handle the largest container ships on the drawing boards today. Some say the entire project will cost $10 billion once you count all the new facilities and other investments the expansion will attract. I have long told architects and engineers that they need to check out Panama. The new locks are expected to be in use by 2015, so not that long from now.
I hadn’t thought much about the implications of the new size of ships that the expanded canal will allow. Maximum ship sizes are governed not by the cargoes they will handle or the destinations their owners want them to go to, but by the depths of the harbors they will see and the size of the canals or waterways they will pass through. The present maximum size for transiting the Panama Canal is the gold standard for designing ships. Known as Panamax, this is the size vessel that most ports want to be able to handle. There are other standards out there. Suezmax is for vessels that must use the Suez Canal (considerably smaller than the Panama Canal). There is a Seawaymax for ships that go up the St. Lawrence Seaway. There is even a super huge Chinamax for ships restricting themselves to using China’s largest ports. Chinamax ships won’t be going anywhere near a canal. For the most of the world, Panamax is the key. And it is about to change.The current Panamax, determined by the size of the locks in Panama, says that a vessel cannot be longer than 965 ft (294.13 m), wider than 106 ft (32.31 m), deeper than 39.5 ft (12.04 m), or taller than 190 ft (57.91 m). The height restriction is to pass under bridges along the canal. These dimensions mean that a current Panamax vessel can carry up to about 5,000 20-foot containers. After the new locks are operating, the new Panamax ships will be able to handle up to 12,000 20-foot containers! These ships are monsters! The new Panamax dimensions will be a length of 1,200 ft (366 m), a width of 160.7 ft (49 m), and a draft of 49.9 ft (15.2 m). The height (air draft) won’t change because the existing bridges aren’t being replaced.
The new Panamax has profound implications for ports – and for anyone who ships by sea. Many of the world’s ports will be unable to handle the new ships. Honolulu, for instance, can barely handle a current Panamax ship, and I just don’t see Hawaii spending mega-bucks to dredge the harbor and ship channel to more than 50 feet. (This puts paid to the old dream of using Honolulu as a transhipment port for ships bound across the Pacific.) Other smaller ports will also feel the pinch.
The new Panamax ships will dominate shipping between the few major ports that can handle them. That implies that smaller vessels will carry cargoes from the new Panamax-capable ports to smaller regional ports that can’t handle these monstrous ships. Kind of a hub and spoke model like the aviation industry uses. I spoke with a shipping expert from Miami who speculated that the new Panamax ships would require a super port somewhere in the Caribbean, Central America or the Bahamas to take cargo off the big ships and redistribute it to smaller ships that can still enter smaller U.S. East Coast or Gulf ports. We are likely to see the same in the Pacific, but it remains to be seen where the super ports will be developed.
You can expect to see shipping rates drop on the routes used by the new Panamax ships. But you will likely see rising rates on the routes served by the smaller, probably older vessels that can still fit into the smaller harbors. Across the Pacific, that means lower prices for crossing the big ocean, but higher costs to push the cargo further along the West Coast or between Asian ports. Those of us out here in the middle will simply be dependent on smaller vessels. But we already are.
