Crate oil
When case oil ( tight. : Case oil ) were in the Seamen and commercial language in the late 19th and early 20th centuries transported oil fractions in a special wooden box packaging referred. It was kerosene u. filled in 5- gallon metal canisters and packed two each in a wooden box. This enabled larger quantities to be shipped before ships and vehicles with built-in tanks and filling systems (“real” tankers and vehicles) were built. In contrast to crate oil, this oil is called tank oil ( bulk oil ). The seven- masted schooner Thomas W. Lawson is an example of this. Before being converted to a tanker, it transported crate oil from Texas to the north along the US east coast .
