Port of Singapore

The Port of Singapore is a collection of facilities and terminals that conduct maritime trade and handle Singapore's harbours and shipping. Since 2015, it has been ranked as the world's top maritime capital. Currently, it is ranked as the world's second-busiest port in terms of total shipping tonnage, while also transshipping a fifth of the world's shipping containers, and half of the world's annual crude oil supplies, alongside being ranked as the world's busiest transshipment port. Furthermore, it was also ranked as the world's busiest port in terms of total cargo tonnage handled until 2010, when it was surpassed by the Port of Shanghai.

Due to the city-state's strategic location, Singapore has served as a significant entrepôt and trading post on an international level for at least two centuries. During the contemporary era, its ports have been regarded not merely as an economic boon for the country, but as vitally important for the country's economic development since Singapore lacks land and natural resources. Additionally, the port is regarded as particularly important for importing natural resources, and then later re-exporting products after they have been domestically refined and shaped in some manner, for example, wafer fabrication or oil refining to generate value-added revenue. The Port of Singapore is also the world's largest bunkering port. Moreover, the majority of ships that pass between the Indian Ocean and the Pacific Ocean go through the Singapore Strait. The Straits of Johor on the country's north are impassable for ships due to the Johor-Singapore Causeway, built in 1923, which links the town of Woodlands, Singapore, to the city of Johor Bahru in Malaysia.
