Kaohsiung Harbor is the largest international commercial port in southern Taiwan and also the largest container exporting centre in Taiwan. In response to the growing trend of large-scale container ships in the international shipping and to strengthen the competitiveness of the Kaohsiung Container Hub port in the Asia-Pacific, a new container base in the hinterland of the southern tip of Kaohsiung Harbor is built. As this new land-reclaimed container base will be completed in phases over a period of years, a temporary cofferdam is needed after the 1st phase of reclaimed work (the 1st phase of the reclaimed area is 43 ha and the total area is 162 ha). Because of the deep water (4–5 m deep after dredging), it is recommended to enlarge the size of single geotextile tube to assure the stability of cofferdam and to achieve the goal of reducing the usage of geotextile tubes.
