Most shippers hear the term “project cargo” before they ever move a project cargo shipment. It comes up in a quote request, an engineering spec, or a call with a freight forwarder — usually without a clear definition attached to it.

This guide defines project cargo in plain terms, explains how it differs from breakbulk and out of gauge (OOG) freight, and walks through how a project cargo shipment actually moves through the Port of Savannah. If you are researching a project cargo shipping company or trying to understand what your quote actually covers, start here.

What Is Project Cargo?

Project cargo is freight that moves as part of a coordinated program rather than as a single, standalone shipment. It typically involves oversized, overweight, or high-value equipment that requires specialized transportation, permitting, and often installation at its final destination.

The defining feature of project cargo is not size. It is coordination.

A single transformer moving from a vessel to a substation is out of gauge freight. A substation expansion involving multiple transformers, switchgear, spare components, and a phased installation schedule is a project cargo program. Same port. Same equipment category. Different scope, different risk, and a different kind of logistics partner required to manage it.

In short: OOG cargo is a dimensional classification. Project cargo is a management discipline that often includes OOG freight, but is defined by the coordination across shipments, modes, and schedules.

Project Cargo vs. Breakbulk vs. Out of Gauge Cargo

These three terms get used interchangeably in the industry, but each describes something different. Shippers who understand the distinction ask better questions and get more accurate quotes.

• Breakbulk cargo: A general term for freight loaded and shipped individually rather than in standard containers. This includes bagged goods, steel coils, palletized freight, and oversized equipment.
• Out of gauge (OOG) cargo: A dimensional classification. Cargo that exceeds the length, width, height, or weight limits of a standard shipping container and requires a flat rack, open top, or specialized trailer.
• Project cargo: A management discipline. Coordinating multiple breakbulk or OOG shipments, transportation modes, permits, staging locations, and installation schedules into a single operating plan.

Most project cargo programs include breakbulk or OOG components. Not every OOG shipment is part of a larger project cargo program. Understanding which one you actually have changes what you should be asking a provider.

What Counts as Project Cargo?

Project cargo spans a wide range of industries. Some of the most common categories moving through the Port of Savannah include:

• Energy infrastructure: Power transformers, switchgear, wind turbine components, and solar infrastructure equipment tied to transmission and utility modernization projects.
• Construction and infrastructure: Cranes, excavators, structural steel, and modular building components, often arriving as multiple pieces across separate vessels and delivery schedules.
• Manufacturing and industrial expansion: Industrial presses, CNC equipment, and production machinery supporting new or expanding facilities across the Southeast manufacturing corridor.
• Oil, gas, and process equipment: Pressure vessels, skids, and process modules that require careful sequencing between fabrication, transport, and site installation.
• Agriculture and heavy equipment: Combines, tractors, and other large equipment shipped in volume or as part of dealer distribution programs.
• Marine and aerospace components: Vessels, hulls, and aircraft or satellite components that require specialized rigging and handling from vessel to final placement.

How Project Cargo Moves Through the Port of Savannah

The Port of Savannah is built to handle both containerized and non-containerized freight, which is part of why it has become a preferred gateway for project cargo shippers serving the Southeast.

Garden City Terminal handles the port’s container volume and is one of the largest single-terminal container operations in North America. Ocean Terminal and Colonel’s Island handle breakbulk, roll-on/roll-off (RoRo), and project cargo, including heavy equipment discharged directly from vessel to trailer.

On-dock rail service through Norfolk Southern and CSX extends the port’s reach into Atlanta and the broader Southeast manufacturing corridor, which matters for project cargo programs that combine ocean, rail, and inland trucking in a single move.

For most project cargo shipments, the process follows a consistent sequence:

• Pre-arrival planning: Confirming vessel schedule, cargo specifications, discharge method, and any special handling or lifting requirements before the vessel arrives.
• Vessel discharge: Moving cargo off the vessel at Ocean Terminal or Colonel’s Island using the appropriate lifting or rolling method for the equipment type.
• Permitting and route planning: Securing state and local permits for oversized or overweight loads, including route surveys, bridge and axle load analysis, and escort coordination where required.
• Heavy haul transportation: Moving cargo from the port to its final destination, whether that is a job site, a manufacturing facility, or a staging yard. See our Heavy Haul Trucking at the Port of Savannah guide for the equipment and permitting details behind this step.
• Staging and storage: Holding equipment when a project schedule requires phased delivery rather than a single drop.
• Rigging and final placement: Setting, aligning, and installing equipment at its final location, which is often the most technical part of the project.

A closer look at what happens after the cargo clears the port gate, including permitting, rigging, and final placement, is covered in our companion guide, Project Cargo at the Port of Savannah: From Vessel to Final Placement.

Why Project Cargo Requires a Different Kind of Provider

A standard drayage or trucking provider can move a container. Project cargo requires a provider who can manage equipment, permits, and schedule risk across an entire program, not just a single load.

Shippers evaluating a project cargo partner should look for a few specific capabilities:

• Asset-based equipment: Owned flat racks, chassis, and specialized trailers mean capacity is not dependent on a third-party carrier network during peak season.
• In-house permitting: A provider who manages permits internally, rather than outsourcing them, can move faster and give shippers real visibility into timing.
• Rigging and millwright capability: Providers who can carry equipment from vessel discharge through final placement reduce handoffs and the coordination gaps that come with them.
• Port-native operations: A team physically present at the terminal understands vessel schedules, local permitting realities, and regional transportation networks better than a provider coordinating remotely.
• Experience with your cargo type: Energy, construction, and manufacturing equipment each carry different handling and sequencing requirements. Provider experience should match the cargo, not just the port.

Savannah Logistics Services operates as an asset-based, port-native provider at both the Port of Savannah and the Port of Charleston, with more than 25 years of experience moving out of gauge and project cargo freight, TWIC-cleared drivers, and in-house rigging and millwright capability from vessel discharge through final placement.

Frequently Asked Questions

What is project cargo shipping?

Project cargo shipping is the transportation and coordination of oversized, overweight, or high-value equipment that moves as part of a larger program, often involving multiple shipments, transportation modes, and an installation schedule at the final destination.

What is the difference between project cargo and breakbulk cargo?

Breakbulk describes how cargo is loaded, individually rather than in a container. Project cargo describes how a shipment is managed, as a coordinated program that may include breakbulk or out of gauge freight alongside standard components.

Does project cargo require special permits?

Most project cargo shipments involving oversized or overweight loads require state and sometimes multi-state permits, along with route surveys and, in some cases, escort coordination. Permit requirements vary by state and by cargo dimensions.

How long does a project cargo shipment take?

Timelines vary by project. A single out of gauge shipment may move in a matter of days. A full project cargo program, involving multiple pieces of equipment and a phased installation schedule, is typically measured in months.

What industries use project cargo logistics?

Energy, construction, manufacturing, oil and gas, agriculture, marine, and aerospace are among the industries that most commonly rely on project cargo logistics to move oversized or specialized equipment.

Does the Port of Savannah handle project cargo?

Yes. Ocean Terminal and Colonel’s Island are equipped to handle breakbulk, RoRo, and project cargo, in addition to Garden City Terminal’s container operations, with on-dock rail service connecting to the broader Southeast.
