An expansion project at the port is currently underway to boost the port's handling capacity, which was designed to handle a maximum capacity of 10 million TEUs.
The first phase of the construction of a new 16-metre (draft) deep-water container terminal, should increase the port's handling capacity by two million TEUs a year.
The first of four 375-metre wharfs is scheduled to be operational by 2011, and the rest by 2013.
Kaohsiung port was the world's sixth largest container port when it handled a record 9.8 million TEUs last year.
Despite hitting new highs this year, it is unlikely to retain its spot as Rotterdam port has overtaken Kaohsiung when it hits 10 million TEUs in November.
