Out-of-Gauge Cargo (OOG)
Out-of-Gauge (OOG) cargo is cargo whose dimensions exceed those of a standard container, so it protrudes beyond the container's length, width or height. Because it will not fit inside a closed box, OOG cargo is carried on flat-racks, open-top containers or as break-bulk, secured to take account of the overhang.
Machinery, transformers, boats, vehicles, pipes and construction plant are typical OOG loads. Shipping them requires special stowage planning, extra lashing and often the loss of adjacent container slots to accommodate the overhang, and attracts out-of-gauge surcharges. Handling OOG well means accurately measuring the overhang in each dimension, planning the stow, and pricing the extra space and effort — a specialised corner of freight closely tied to project and heavy-lift logistics.
Out-of-gauge cargo breaks the neat economics of the container — it overhangs, blocks neighbouring slots and needs bespoke stowage and lashing, all of which must be measured and priced correctly. Misjudge the overhang or the surcharges and a project shipment loses money or safety. OOG handling is where standard container freight meets heavy-lift discipline.
How is out-of-gauge cargo shipped?
On flat-racks or open-top containers, or as break-bulk, with special stowage and lashing for the overhanging dimensions.
Why does OOG cargo cost more?
The overhang often blocks adjacent container slots and needs extra planning and securing, so out-of-gauge surcharges apply.
