When it comes to the size, Singapore doesn't disappoint either. With nearly 31 million TEUs in 2015, Singapore has remained a constant powerhouse in shipping—it was once the largest port in the world before Shanghai that crown.

A key port for ships flowing through the Strait of Malacca, Singapore has over 200 cranes to deal with the constant flow of traffic.
