THE 8,400-TEU Maersk Surabaya ran aground, and was later refloated, in the Savannah River enroute to the Port of Savannah, reported Ventura, California's gCaptain.
The AIS (automatic identification system) showed the Danish-flagged ship up against the bank of the river with tugs in position around the vessel's stern.
The US Coast Guard said the response is underway after the ship ran aground, but was still awaiting details on the incident.
It appears the vessel was refloated about two hours after its initial grounding, according to AIS data from ship tracking and maritime analytics provider MarineTraffic.com.
It appears the ship may have been blocking a good portion of the shipping channel before she was refloated hours later.
The Maersk Surabaya was built in 2006 and was inbound from the Port of Charleston when the incident occurred.
The Port of Savannah, the second-busiest port on the US east coast after New York/New Jersey, experienced its third-busiest month on record in April as retailers replenished depleted inventories and make early orders ahead of the peak shipping season.
The surge of imports has caused the containership backlog to swell to about 25 currently.
The Maersk Surabaya previously made headlines in 2021 when she dropped anchor and damaged a critical underwater cable connecting Western Australia with Singapore. Australia subsequently arrested and charged the ship's master with negligent conduct.
