OOG Shipping FAQs
Essential answers regarding Flat Racks, Open Tops, and over-dimensional freight shipping.
What is Out of Gauge (OOG) shipping?
Out of Gauge (OOG) shipping refers to ocean freight cargo whose dimensions exceed the standard dimensions of a 20ft or 40ft dry container in length, width, or height, requiring specialized equipment like Flat Racks or Open Tops.
What is the difference between Flat Rack and Open Top containers?
Flat Rack containers have no side walls or roof, making them ideal for over-width and over-length machinery. Open Top containers have hard side walls but a removable tarpaulin roof, designed specifically for over-height cargo requiring top-loading by crane.
How are OOG slot loss surcharges calculated?
Slot loss surcharges are based on the number of container slots on a vessel that cannot be used because your cargo protrudes into adjacent vertical or lateral spaces.
What cargo securing standards are enforced for OOG ocean transport?
OOG cargo must be lashed, blocked, and braced in full compliance with IMO/IMO-CSO regulations using certified steel chains, wire ropes, turnbuckles, and dunnage certified for marine transport.
How far in advance should OOG container space be booked?
Due to equipment availability and carrier technical approvals, OOG shipments should ideally be booked 2 to 4 weeks prior to the target vessel departure date.
Do you provide inland drayage and port handling for OOG equipment?
Yes, we handle complete end-to-end logistics including heavy haul transport, specialized lowboy trailer drayage, port stevedoring, crane rigging, and terminal ops.
