It's a lot of wheels turning, all day long, all throughout the Wando Welch terminal.
"It's non-stop traffic," Timica Carter said. She's a container handler and first-year employee at the port.
Officials say the month of March was their busiest ever, with workers unloading more than 110,000 containers.
Carter is one of 140 new employees hired since January 2017 at the Wando Welch terminal, which officials say more than doubles their workforce in that time.
"It's just massive for trade," Colt Davis said. Davis is a heavy lift mechanic, which involves maintenance on the cranes you can see for miles away around the Lowcountry.
"You really don't think much of it but then you get in that elevator and you step out, now you know you're in a different world really," Davis said. He started working at the Wando Welch terminal in May 2017.
A 2015 study by the USC School of Business said the port has an annual economic impact of $6.3 billion in the Lowcountry, and that one in every 20 Lowcountry jobs is tied to the port.
"I feel like it's starting to click and starting to piece together a little bit here and there," Davis said. "Trying to pick up as much as you can. Because there really is a lot of info to know in this field."
Timica Carter says she's the only woman operator at the Wando Welch terminal, but she's okay with that.
"A lot of companies you go to work and they say hey we're closing down...I don't see the port closing down any time soon."
Officials say workers unload around 1,000 containers from each ship that pulls into Lowcountry ports.
