What is the difference between out-of-gauge and break bulk cargo?

If the item or items to be transported are too large to fit inside a standard container, it is deemed to be ‘out of gauge’ (OOG). Such cargo might require an open top container, platform or flatrack.

If, however, the cargo is too big to be loaded onto a single flatrack, it is termed as ‘breakbulk’ or project cargo. Typically we have to load this type of cargo across multiple flatracks on the deck of a vessel.
