What changes in Charleston
Sector Charleston covers both Charleston and Savannah, which is worth knowing: two of the busiest South Atlantic container ports fall under one Captain of the Port. Policy and posture are therefore consistent between them in a way operators can rely on.
The terminals are modern and their facility security plans reflect that, with structured access control and credentialing. Container operations mean the security load is concentrated at the gate and gangway rather than distributed across a large shoreside workforce.
- Sector Charleston covers both Charleston and Savannah under one COTP.
- Policy and posture are consistent across the two ports as a result.
- Modern terminals operate structured access control under 33 CFR 105.
- Container operations concentrate the security load at gate and gangway.
- Hurricane season brings port condition changes that interact with security posture.

The Charleston cluster
Charleston competes directly with Savannah for South Atlantic container volume and has invested heavily in harbour depth to take larger vessels on more tides. The port is efficient and modern, with the Leatherman terminal adding capacity, and the trade is overwhelmingly containerised rather than bulk or energy.
- Deep harbour after federal deepening
- Modern container terminals
- South Atlantic gateway
- Strong inland rail links
The fundamentals
After 2001 the IMO produced the ISPS Code, and the United States passed the Maritime Transportation Security Act in 2002. The two were developed in parallel and are broadly aligned, but the US did not adopt ISPS as its domestic law. It wrote its own, in 33 CFR Parts 101 to 106.
The practical consequence is that in a US port you are inspected against the Code of Federal Regulations, not against the ISPS Code. Most of the substance matches. The vocabulary, the thresholds and the enforcement do not.
This is the shared explanation, common to every market. The full treatment is in MTSA Explained: How US Port Security Actually Works.
Frequently asked questions
Does one Coast Guard sector cover both Charleston and Savannah?
Yes — Sector Charleston is the Captain of the Port for both. That gives consistent policy and posture across the two busiest South Atlantic container ports, which is useful for operators running services that call at both.
How does container operation affect the security load?
It concentrates it. Unlike ro-ro or breakbulk, where a large workforce moves on and off continuously, container operations keep the control points at the gate and the gangway, which makes access control more manageable.
