Heading into the twentieth century, fortunes were often made in Singapore via trade, tin smelting, pineapple canning, mining, and rubber processing.  In 1891, the predecessor of what is now the Shell global group began storing oil on the nearby island of Pulau Bukom.  Thus began a long-standing business relationship of over 120 years.  Today, the 500,000 barrels-per-day Bukom refinery ... is “the largest Shell refinery in the world in terms of crude distillation capacity.”  Because of successful ventures such as this, by the year 1903 Singapore had become the world’s seventh busiest port.  Since that time, Singapore has climbed the charts rapidly and currently maintains the world’s second busiest port, with container traffic measured behind only that of the Port of Shanghai, China.
