25
Tankers (marine)
Transport very large quantities of liquid products.Can carry different products in segregated tanks. Petroleum carriers - transport crude or finished petroleum Chemical carriers - transport many different chemical products Liquified flammable gas carriers - transport liquified natural gas (LNG) and liquified petroleum gas (LPG)
26
Cargo Vessel
Bulk Carriers - liquids or solids Break Bulk Carriers - variety of materials in different containers such as pallets, drums, bags, boxes, and crates Container Vessels - cargo in standard intermodal containers with standard widths and varying heights and lengths Roll-on/Roll-off Vessels - large stern and side ramp structures that are lowered to allow vehicles to be driven on and off the vessel Barges - typically box shaped, flat decked vessels used for transporting cargo. Not self propelled, require pushing or towing
