When steel pipe cargo is going to be transported in a RO-RO type vessel, it shall be packed accordingly (in units as super packs, special racks or bundles defined on PRD04941 “Steel Pipes Packing”) in order to facilitate its handling within the vessel. Pipes are entered into the vessel through a ramp by means of trucks, trailers or mafies. Once inside the vessel, pipes units are handled and stowed by forklifts.
