Out-of-Gauge (OOG) cargo is freight that exceeds the dimensions of a standard shipping container. It may be wider, longer, taller or heavier than standard container limits and therefore requires specialist equipment, planning and handling.
At DC Global Freight, we understand that every OOG shipment is different. Moving industrial machinery, generators, steel fabrications or offshore equipment requires careful preparation long before the cargo reaches the port. Successful movements rely on accurate planning, experienced project coordination and clear communication between every party involved.
What is Out-of-Gauge Cargo?
Cargo is considered out-of-gauge when it cannot fit within the internal dimensions of a conventional 20ft or 40ft container. Depending on its dimensions, it may travel on a flat rack, in an open top container or as breakbulk cargo.
Typical examples include:
• Industrial machinery
• Generators
• Process vessels
• Offshore equipment
• Construction machinery
• Large fabrications
• Tanks and pressure vessels
Planning an OOG Shipment
Every shipment begins with obtaining accurate cargo dimensions and weight. We also review lifting points, centre of gravity, packaging, transport restrictions and destination requirements.
Planning normally includes:
• Equipment selection
• Road transport assessment
• Route surveys where required
• Port handling arrangements
• Lifting plans
• Customs documentation
• Vessel selection
• Delivery planning
Choosing the Right Equipment
Flat rack containers are often the preferred solution for cargo that exceeds the width or height of a standard container. Open top containers can be suitable where cargo exceeds height limitations but remains within width restrictions.
Where cargo is exceptionally large or heavy, breakbulk shipping or charter vessels may provide the safest and most economical solution.
From Our Experience
One of the most common causes of delay is discovering transport restrictions after collection has been arranged. Confirming bridge clearances, escort requirements, crane availability and port capabilities during the planning stage reduces both cost and project risk.
Securing the Cargo
Correct lashing and securing are essential. Every cargo item should be secured in accordance with recognised industry practices, taking account of weight distribution, lifting points and forces experienced during road and sea transport. Proper cargo protection also helps prevent weather damage and corrosion during transit.
Lessons from the Field
The sea voyage is rarely the greatest challenge. More often, the success of an OOG shipment depends on the planning completed before the cargo leaves the supplier. Time invested in preparation almost always saves time later in the project.

Frequently Asked Questions
What does OOG mean?
Out-of-Gauge refers to cargo that exceeds the dimensions of a standard shipping container.
Can OOG cargo travel on normal container vessels?
Yes. Many OOG shipments move on scheduled liner services using flat rack or open top equipment.
Does every shipment require a route survey?
Not always. Surveys are recommended where cargo dimensions or local restrictions create additional transport challenges.
When should I contact a freight forwarder?
As early as possible, ideally before packing or transport arrangements have been made.
