SST - History of Seagoing Oil Tankers
The term "SST" is often used interchangeably with "Very Large Crude Carrier" (VLCC), referring to large ocean-going tankers designed for transporting crude oil. In the context of maritime transport history, these vessels have played a significant role since the end of World War II.
A brief history of seagoing oil tankers can be traced back to the late 19th century when small wooden steam tankships were introduced. However, it was during the early 20th century that efficient steel-hulled ships became dominant. One of the earliest major milestones came after World War I, when oil tankers began to replace sailing ships due to their speed and efficiency.
In the years leading up to World War II, many countries built their own tanker fleets. For example, the United States had developed its largest fleet by 1938. By this time, tankers were an essential part of international trade, facilitating the distribution of petroleum products worldwide.
After World War II, there was rapid growth in the demand for oil, which led to a corresponding expansion in tanker capacity. This period also saw the introduction of the modern Very Large Crude Carrier (VLCC). These vessels could carry over 200,000 deadweight tons, making them significantly larger than earlier designs. The VLCCs were typically equipped with double bottom tanks and triple-bottom ballast tanks to improve safety and reduce risk of oil spills.
By the 1970s, U.S. flag tankers were phased out, replaced largely by vessels from other countries such as Norway and Japan. This shift coincided with a global recession in the shipping industry, causing many older tankers to be scrapped. Despite challenges, new technologies like computerized navigation systems and improved engine efficiencies helped revitalize the sector.
Today, the world's seagoing oil tanker fleet remains integral to global energy markets. With ongoing advancements in technology and environmental concerns, future developments will likely continue to reshape the landscape of international petroleum transportation.
