The history of the oil tanker is part of the evolution of the technology of oil transportation alongside the oil industry. ==Background== The technology of oil transportation has evolved alongside the oil industry. Although use of oil reaches to prehistory, the first modern commercial exploitation dates back to James Young's manufacture of paraffin in 1850.〔Chisholm, 19:316.〕 In the early 1850s, oil began to be exported from Upper Burma, then a British colony. The oil was moved in earthenware vessels to the river bank where it was then poured into boat holds for transportation to Britain.〔Chisholm, 19:320.〕 In the 1860s, the Pennsylvania oil fields became a major supplier of oil, and a center of innovation after Edwin Drake struck oil near Titusville, Pennsylvania.〔 The first oil well in the United States was dug here in 1859, initially yielding around ten barrels per day.〔Woodman, 1975, p 175.〕 Within two years, the Titusville field was providing .〔 The invention of oil refining led to the availability of kerosene as lamp oil, which has a smokeless combustion in contrast with the until then highly used whale oil. The lamp oil became known as ''Pennsylvania Kerosine''. Due to overfishing, whale oil became rare and expensive. By this time, petroleum oil had already begun to supplant fish, whale, and vegetable oils for applications such as indoor and outdoor lighting, and transatlantic export had already begun.〔 Break-bulk boats and barges were originally used to transport Pennsylvania oil in wooden barrels.〔 But transport by barrel had several problems. The first problem was weight: the standard empty barrel weighed , representing 20% of the total weight of a full barrel.〔Tolf, 1976, p. 54.〕 Also barrels were leaky, and could only be carried one way.〔 Finally, barrels were themselves expensive. For example, in the early years of the Russian oil industry, barrels accounted for half the cost of petroleum production.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of the oil tanker」の詳細全文を読む スポンサード リンク
