When a piece of cargo does not fit inside a standard container, it requires special handling. Oversized or Out of Gauge (OOG) cargo requires careful planning, specialized equipment, and experience. In this guide, we explain what it is and how it is transported.
What Is OOG Cargo (Out of Gauge)?
Out of Gauge (OOG) cargo refers to any cargo that, due to its height, width, or length, exceeds the internal dimensions of a standard closed container and protrudes beyond it. Typical examples include machinery, pipes, steel structures, generators, and oversized vehicles.
What Equipment Is Used to Transport It?
Depending on the type and dimensions of the cargo, different specialized equipment may be used:
- Flat Rack: An open platform without side walls, suitable for cargo that protrudes from the sides.
- Open Top: A container with an open roof, used for cargo that must be loaded from above or exceeds the container's height.
- Breakbulk: Loose cargo that is not containerized and is transported as individual pieces in the vessel's cargo hold.
Key Considerations When Moving Oversized Cargo
A successful OOG shipment starts with careful planning:
- Technical assessment of dimensions, weight, and critical points along the route.
- Calculation of stowage, lashing, and securing requirements to ensure the cargo remains stable throughout the journey.
- Management of special oversized cargo permits when required.
- Coordination of cranes and loading and unloading operations.
OOG and Project Cargo: Close Relatives
OOG cargo is often part of larger projects. When a shipment involves multiple pieces, engineering requirements, and coordination among several parties, it becomes Project Cargo, which we manage through an integrated approach.
