Over Sized Cargo
Over height cargo in Open Top Container, Over width and/or Over height cargo on Flat rack containers create dead spaces or voids on board.
Following items are observed when loading Special Cargo:
1. Can it be securely lashed?
Top-heavy cargo may be in danger of falling. Cargo that protrudes at the sides should be properly balanced.
In case of heavy and/or tall cargo, center of gravity needs to be shown with care mark.
2. Are they completely protected from wetting?
Cargo on flat rack containers is different from those in water-tight dry containers since cargo on flat rack containers is exposed to seawater and rain.
Open top containers have canvas covers on top which, however, cannot be said perfect against the air outside/water drop.
If cargo is stowed in the hold, it is still possible for rain to permeate the cargo while it is stored in the terminal or transported overland, thus water proof packaging is necessary.
3. Restrictions on inland transportation.
Even when lashings are secured at the factory, think about getting the cargo from there to the harbor. When cargoes that exceed regulations are transported, special permission is required in advance. Consult with NYK in advance about regulations in destination countries.
4. Terminal/Vessel Restrictions.
Overwidth cargo, such as cargo that bulges out over the sides of the container, is limited by the cell structure of the vessel when it is loaded into the hold. At terminals that use straddle carriers, the overwidth side is restricted to 10 cm (3.9inches) of protrusion.
On board restrictions are determined primarily by the shape of the entry guide of the cell structure. The holds of containerships are fitted with entry guides around the entrance to the hold in order to enable containers to be easily guided into slots. These entry guides protrude approximately 50cm (19.6 inches) from the interior of the hold.
If overwidth cargo is stowed covering the cornerposts of the container it may become incapable of being properly loaded into the hold due to the protruding part of the cargo contacting the entry guide.
Therefore, when overwidth cargo is loaded into a flat rack container, be sure to load it so that the front and back of the container are at least 50cm (19.6 inches) from the front and back of the slot (cell).
