Delivering Results

MainOcean Carolinas

Charleston Freight Station and Conquer Logistics joined the MainOcean family in Charleston, South Carolina as MainOcean Carolinas.

With two locations servicing the Port of Charleston, we offer 300,000 sq. feet of dry warehousing space, ample truck/container yards, and depth of experience in specialized cargo handling and packing – all from convenient and strategically-located facilities close to SCSPA terminals and inland routes.

MainOcean  acquired GT Logistics, a 3PL provider based in Greer, South Carolina, in June 2023. The expansion into the Upstate is part of MainOcean’s strategic plans to be near Inland Port Greer and expand their warehouse and logistics capabilities to better serve its customers in South Carolina and the Southeast.
