Every Week at Garden City Terminal, a Vessel Discharges Cargo That Does Not Fit
A transformer too tall for a standard box. A wind turbine nacelle riding a flat rack with custom lashing. A piece of construction equipment, an oversized agricultural rig, or a 45-ton industrial press whose center of gravity turns a routine road move into a multi-state over-dimensional permit job. That cargo arrives at the Port of Savannah needing one thing: an operator who has moved it before.
Savannah Logistics Services is the new brand for the operating team that built its reputation as Savannah River Logistics. OOG freight has been our discipline from the start — twenty-five years of flat rack, open top, breakbulk, and heavy lift at GPA. Coverage now extends to the Port of Charleston as well.
Out of Gauge Is a Discipline, Not a Service Line
Out of gauge cargo at the Port of Savannah covers anything that breaks ISO container dimensions: flat rack container drayage, open top container moves, breakbulk shipping out of Savannah, Georgia, project cargo, and heavy-lift pieces that travel over-height, over-width, over-length, or overweight.
Each category has its own equipment requirement, its own lashing standard, its own permit pathway, and its own risk profile.
That last point matters. There is no generic OOG playbook. There is the playbook an operator has written by moving the cargo through GPA, vessel by vessel — and there is everything else. A shipper who treats OOG freight as a commodity service learns the difference the hard way: in detention costs, missed project deadlines, and damaged equipment.
What Counts as Out of Gauge?
If your shipment meets any of the criteria below, it requires specialized handling, equipment, and planning:
- Over length: Exceeds 40-foot or 45-foot container length
- Over width: Exceeds 8-foot container width
- Over height: Exceeds 9′6″ container height
- Overweight: Exceeds container weight limits or state road weight limits
- Awkward configuration: Shape, fragility, or attachment points prevent standard container loading even when dimensions are within limits
The classification matters. Once a shipment is OOG, it needs specialized trailers, multi-state over-dimensional permits, route surveys, and in many cases escort vehicles or police escorts. Trying to move it as standard freight is not a shortcut — it is a violation.

Standard container drayage is forgiving. If a chassis is unavailable Tuesday, your container probably ships Wednesday. The cost is detention, not catastrophe.
Flat rack container drayage in Savannah is not forgiving. A flat rack drop-off without dedicated, properly equipped chassis on the receiving side becomes a vessel discharge problem that becomes a port problem that becomes a customer relationship problem.
That is why our team operates as an asset-based logistics provider, not a brokerage. We run more than 80 company-owned tractors and over 300 chassis, including the specialized equipment that flat rack, open top, and heavy-lift moves require. Every driver is TWIC-cleared and familiar with Garden City Terminal gate procedures. When a vessel discharges OOG cargo, our fleet is staged. There is no scramble. The asset is owned and the driver is on payroll.
For oversized cargo shipping work in Georgia, that operating model is the entire job. A broker does not own the chassis they promise. An asset-based OOG logistics East Coast port operator does.
| What You Need | Brokered OOG Provider | SLS — Asset-Based |
|---|---|---|
| Dedicated chassis when a flat rack discharges | Depends on third-party availability | 300+ chassis owned — fleet is staged |
| Tractors ready for OOG dispatch | Brokered to whoever answers the phone | 80+ company-owned tractors on payroll |
| TWIC-cleared drivers, GPA gate familiar | Variable — whoever the broker found | Every driver TWIC-cleared, knows GPA |
| Permits — GA, SC, FL, AL, TN | Outsourced to a third party | In-house, every state on route |
| Local warehouse for OOG staging | Third-party site, multiple handoffs | Morgan Lakes facility — 15 mi from port |
| Single point of accountability | Calls bounce between dispatch and broker | One operator, owns the move start to finish |
The Real Cost of Getting It Wrong
OOG buyers do not fear inconvenience. They fear catastrophic, expensive, and visible failure. Here is what actually happens when an OOG move is mishandled:
| Mistake | What It Actually Costs |
|---|---|
| Wrong lashing pattern on a flat rack | Cargo shift in transit; damaged equipment; insurance claim; project delay with installation crew on the clock |
| Missed escort permit | Load held at state line until escort arranged; per-day storage; fines for moving without authorization |
| Chassis that cannot accept the load | Vessel discharge stops; flat rack returns to terminal; port relationship strain; demurrage accrues by the hour |
| Skipped route survey | Driver hits a low bridge, weight-restricted road, or construction zone mid-transit. Cargo damage and infrastructure liability follow. |
| Re-broker chain breaks | Quote-holder loses visibility; driver doesn’t answer; nobody knows where the load is or who is accountable. |
Every failure mode in the table above is preventable — but only when the carrier, the routing, and the permits are managed by people who do this every week, not occasionally.
↑ Back to ContentsEquipment Matched to Your Cargo
The right trailer is the difference between a routine delivery and a six-figure incident. Five specialized equipment types make up the OOG toolkit, and each one solves a different problem.
| Equipment | Spec Limits | Best For | Why It Matters |
|---|---|---|---|
| Flat Rack | 20ft & 40ft; up to ~88,000 lbs. payload | Over-width / over-height machinery, wind nacelles, project cargo | Collapsible ends and open sides for side- and top-loading. Custom lashing handled in-house. |
| Open Top | 20ft & 40ft; standard container width | Over-height cargo that fits standard width; top-loading required | Removable tarp roof enables crane loading without changing container footprint. |
| RGN Trailer | Up to ~150,000 lbs. with axle configuration | Heavy equipment, transformers, industrial presses | Detachable gooseneck allows ground-level loading; multi-axle weight distribution. |
| Lowboy | Deck height as low as 18″; up to ~80,000 lbs. | Very tall cargo, construction equipment, wind tower sections | Lowest available deck height clears overhead obstructions on permitted routes. |
| Step Deck | Two-level deck; up to ~48,000 lbs. | Medium-height cargo, mixed loads, Ro-Ro freight | Two-level deck handles both standard and over-height items on a single trailer. |
How SLS Picks the Right Equipment
Cargo specifications drive the equipment choice — not whatever a carrier happens to have available that week. Once your dimensions and weight are confirmed, we match against trailer capabilities from our owned fleet, routing constraints (low clearances eliminate some options), and weight distribution requirements. The wrong trailer creates problems no permit can fix.
↑ Back to ContentsThe Permit Problem No One Talks About Until It Stops the Load
Every OOG move out of the port has a road problem to solve. Bridge clearances, weight-restricted routes, escort vehicle requirements, and county-by-county over-dimensional permit windows.
Georgia, South Carolina, Florida, Alabama, and Tennessee each have their own rules — and a misread on any of them parks the load at a county line.
Permits and route surveys belong in-house. OOG over-dimensional permits in Georgia are too time-sensitive and too consequential to outsource. Heavy-lift energy equipment moves out of Savannah to substations carry transformers and switchgear that cannot tolerate route improvisation. Wind energy OOG freight from Savannah moves turbine blades, nacelles, and tower sections that require coordinated escort planning across multiple jurisdictions. Construction equipment OOG shipping out of GPA demands the same operating discipline.
Eight Questions Every OOG Shipper Should Ask
When shippers call our team for an OOG freight quote at GPA, the conversation that follows tells us more than any RFQ. The questions a shipper asks are the questions they wish they had asked their last operator. For shippers evaluating any OOG provider at the Port of Savannah, here is the checklist we recommend.
| # | Ask Every OOG Provider | What a Strong Answer Tells You |
|---|---|---|
| 01 | How many years moving OOG freight at GPA? | OOG mastery is built shipment by shipment. Years equal scenarios survived. |
| 02 | Owned tractors and chassis — or brokered? | Asset-based fleets do not run out of equipment when a flat rack arrives. |
| 03 | Is flat rack and open top container inventory dedicated? | Pulled-from-pool gear delays flat rack drayage moves. |
| 04 | Are over-dimensional permits handled in-house? | Permits in Georgia and across the Southeast cannot wait on third parties. |
| 05 | Have you moved this specific cargo type before? | Wind, transformer, breakbulk, and Ro-Ro each carry distinct risks. |
| 06 | What is your route survey process? | A weak survey on heavy-lift cargo stops the load at a county line. |
| 07 | Are you connected to local warehousing? | OOG storage close to port closes third-party staging gaps. |
| 08 | Who is the single point of contact? | OOG cannot be run by committee. One accountable operator is essential. |
None of these questions are unfair. Any operator should answer them quickly and specifically. If the answers are vague, that is the answer. SLS will answer all eight, in writing, before any quote is signed. That is what twenty-five years of reputation requires.
↑ Back to ContentsSavannah and Charleston: How SLS Covers Both
SLS operates as the OOG and project cargo specialist for the Port of Savannah, where the operating team has 25 years of GPA experience. Coverage extends to the Port of Charleston using the same asset-based fleet, the same TWIC-cleared drivers, and the same in-house permit team.
| Capability | Port of Savannah | Port of Charleston |
|---|---|---|
| Primary Terminal | Garden City Terminal | North Charleston Terminal |
| Flat Rack & Open Top Pickup | Same-day available — 25 years of GPA experience | Coordinated pickup available |
| TWIC-Cleared Drivers | 80+ on payroll, GPA gate procedures known | Same fleet operates Charleston routes |
| Warehouse Staging | Morgan Lakes facility — 15 mi from terminal | Same SLS facility serves Charleston routing |
| In-House Permits | GA, SC, FL, AL, TN coordinated in-house | Same multi-state permit team |
Which Port Should You Use?
- Savannah is typically preferred when you need same-day port pickup with deep GPA operating familiarity, staging at our Morgan Lakes facility, or you’re moving cargo destined for the Southeast manufacturing corridor.
- Charleston is typically preferred when your cargo’s origin or destination favors I-26 / I-95 north routing, or when Charleston-specific ocean carrier schedules align with your ship date.
SLS can quote both options when it is not obvious which is better, so you see the full picture before committing to a port.
↑ Back to ContentsWhy the Port-to-Warehouse Connection Matters for OOG
OOG cargo rarely travels straight from vessel to final delivery. It often needs interim staging, transloading, or temporary OOG oversized cargo storage in Savannah while permits, end-user crews, or project schedules align.
For OOG freight shippers at the Port of Savannah, when staging happens at a third-party site disconnected from the drayage operation, costs and risks accumulate at every handoff.
The SLS facilities at Morgan Lakes in Pooler, GA — the same yards and warehouse footprint our team has operated for twenty-five years under the Savannah River Logistics name — sit 15 miles from the Port of Savannah. For OOG cargo that needs to wait, get reconfigured, or stage before a project window opens, that proximity and continuity of operating team eliminate the third-party handoff that often costs shippers more than the drayage itself.
