Port of Savannah Seeks to Deepen Shipping Lane Again

SAVANNAH, Ga. — Just 18 months after crews finished the $1 billion dredging of the Savannah River channel, the Georgia Ports Authority wants to study deepening the shipping lane again.
Lauded as one of Georgia’s largest economic development projects, the last deepening helped Savannah become one of the busiest ports in North America. Now, officials say, to remain competitive, a new round of deepening is needed amid a massive shift in international trade routes between the U.S. East Coast and Asian manufacturing hubs.
“By the time we completed the last deepening, we were again behind the times,” Georgia Ports Authority CEO Griff Lynch said. “There is a need to get the port and river ready for the future and position us for success.”
Georgia’s ports are huge economic drivers. The Port of Savannah and other ports authority facilities support 561,000 jobs and contribute $59 billion annually to the state’s gross domestic product, a recent study showed. The ports’ business has nearly doubled over the last decade, and officials have announced expansion projects that will significantly boost container capacity by 2030.
The latest dig dropped the river bottom to 47 feet, deep enough to handle the biggest ships that cross the Pacific Ocean and transit the expanded Panama Canal en route to Savannah and other East Coast ports.

But growth in manufacturing in Asian nations outside China — including India, Thailand and Vietnam — has shippers sending more goods west on bigger vessels from Asia through Egypt’s Suez Canal and across the Atlantic Ocean. These ships require deeper and wider channels to access ports.
Another deepening in Savannah is likely to take years, require bipartisan political support in a fractured Congress and could involve hundreds of millions of state funds, just as the last one did.
The most recent expansion wrapped in March 2022, more than 25 years after the Army Corps of Engineers conducted a similar deepening study. Port authority officials say a new effort will also require widening the river channel at strategic points and would take approximately a decade.
A new round of dredging is likely to face fierce opposition from environmental advocates. The most recent project required hundreds of millions of dollars spent to preserve or build new wetlands and to protect wildlife.

Ports authority officials have already requested authorization from Congress to seek a study. Georgia’s Democratic U.S. Sens., Raphael Warnock and Jon Ossoff, and U.S. Rep. Buddy Carter, a Republican who represents coastal Georgia, have voiced their support.
Lynch is expected to highlight the need for enlarging the harbor during the Oct. 12 annual Savannah State of the Ports luncheon. The changes are part of broader expansion plans that include elevating the roadway of the Talmadge suspension bridge over the Savannah River and construction of a third container terminal.
“This is the time to reflect, build and be ready for the next wave of cargo,” Lynch said in previewing his State of the Port address. “The East Coast is in a good position to add market share. The question for us is: Will we be in the best position to be competitive?”
Why wasn’t the last dredging deeper?
Engineers based the last Savannah River deepening on the then-planned expansion of the Panama Canal.
The canal’s locks system limits the width of ships. Vessels built to carry more than the equivalent of 15,000 20-foot-long cargo containers can’t transit the canal.
The last dredging met the minimum depth required for fully loaded “post-Panamax” ships to reach Savannah at all tides. The original target was 48 feet, but concerns about wetlands damage and impacts on the Floridian Aquifer, the main source of drinking water for 10 million Americans, led to a scale-back.

Concerns about the aquifer will likely be one of the hurdles supporters of deepening will have to overcome. Anticipating such pushback, Lynch vowed the ports authority would not advocate for “anything that impacts the aquifer.”
Bigger ships, known as “Suezmax” vessels, carry up to 9,000 more containers than the Panama Canal freighters. They need at least 50 feet of depth below the waterline when fully loaded with cargo.
Why trade is shifting to bigger ships
Nearly a quarter of all containerships on order or under construction today are for Suezmax vessels, according to a February report from shipping consulting firm Alphaliner. The trend is due in part to the emergence of India, Thailand and Vietnam as manufacturing rivals to China.
Companies have diversified their factory locations over the last five years, adopting what Savannah-based maritime trade consultant Walter Kemmsies calls a “China plus one” strategy. Driven by the tariff war launched by then-President Donald Trump against China in 2018 and exacerbated by China’s adversarial stances against the U.S., the manufacturing movement to west Asia is accelerating.

Ships departing from those ports can reach U.S. East Coast ports via the Suez as quickly as they can by heading across the Pacific and through the Panama Canal. The wider Suez allows the bigger ships, creating economies of scale for shippers.
According to Kemmsies, Savannah is a preferred port because of geography and management. Cargo in Savannah can reach Southeast and Midwest destinations within two days of being unloaded. And the state-run entity has not suffered the labor disruptions that have plagued other U.S. ports.
What would another deepening involve?
Another round of dredging would not only deepen the channel but widen the lane as well.
The Port of Savannah sits 22 miles from the river’s mouth, and the inland stretch is not straight. The channel includes several of what Lynch calls “chokepoints” where ships can’t pass each other. Vessels often must stop and wait for another ship to clear these narrow sections before proceeding.

Suezmax ships measure 1,300 feet long and 24 containers wide and would create more of a logjam.
The channel study would focus on ways to address these tight corners, Lynch said.
“Carriers can’t afford to have their vessels sitting,” Kemmsies said. “For a port to be attractive to the ocean carriers, the port must be cost-effective and efficient. The navigation channel has to have the capacity.”
Study authorization would come as part of a renewal of the Water Resources and Development Act (WRDA) next year. Up for reauthorization every two years, the WRDA enables the Corps of Engineers to take action on a specific list of projects meant to improve rivers, harbors and other bodies of water. WRDA authorization does not include funding for those initiatives.
Georgia lawmakers lobby for the inclusion of state projects in the WRDA. A spokesperson for Ossoff said the Democrat “continues working closely with the GPA to support economic development and the growth of Georgia’s world-class ports,” while a spokesperson for Warnock, a Savannah native, said the Democrat is “supportive of authorizing a study which would assess the benefits of deepening and widening the port of Savannah harbor to allow it to remain competitive on the world stage.”
Carter offered a full-throated endorsement of the study.
“Georgia’s First Congressional District is experiencing tremendous growth, and it is encouraging that the Georgia Ports Association is planning for this expansion by exploring options to widen and deepen the Port of Savannah, a major economic engine for our state,” Carter said. “I look forward to working with GPA to ensure it can continue to grow with the appropriate support from the federal government.”
