What changes in Galveston
Galveston shares Sector Houston-Galveston as its Captain of the Port, and its security profile splits along the same lines as its commercial one: cruise terminals with passenger screening obligations, and offshore lightering with a quite different set of questions.
Offshore transfers raise issues the shoreside regime does not directly address. Two vessels working together outside a facility means the security relationship is vessel-to-vessel under Part 104 rather than vessel-to-facility under Part 105, and the Declaration of Security is between the ships.
- Sector Houston-Galveston is the COTP for both ports.
- Cruise terminals carry passenger screening obligations under 33 CFR 105.
- Offshore lightering makes the security relationship vessel-to-vessel, not vessel-to-facility.
- Declaration of Security between the two ships applies during transfers.
- Texas City refining berths carry high-consequence cargo requirements.

The Galveston cluster
Galveston matters commercially for two things that have nothing to do with each other: a growing cruise business, and its position at the seaward end of the Houston Ship Channel where the designated offshore lightering area sits. Deep-draft tankers that cannot transit the channel loaded discharge part cargo here first.
- Designated offshore lightering area
- Gateway to the Houston Ship Channel
- Growing cruise operation
- Texas City refining berths
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
How does security work during an offshore transfer?
It becomes a vessel-to-vessel relationship under 33 CFR 104 rather than the vessel-to-facility relationship of a berth call. The Declaration of Security is between the two ships, and each master remains responsible for their own vessel's security plan.
Is Galveston covered by the Houston COTP?
Yes — Sector Houston-Galveston covers both, so policy is consistent across the offshore lightering area, the Galveston berths and the Houston Ship Channel.
