The subject of investigation in this study is the extension of Ulsan Port in the south east of the Korean peninsula. The existing port of Ulsan is mainly an industrial port, with refineries, petro-chemical industries, car manufacturing and ship building. The Korean government is setting up an overall port development strategy, in which Ulsan Port must be transformed from a mainly industrial port to a multi purpose port. Besides this transformation, the existing cargo throughput is envisaged to increase significantly over the next decades. These trends require the development of new port facilities in the Ulsan region. A consortium of Korean consultants already has drafted a master plan for the Ulsan Port development. This plan contains many less preferable solutions. Therefore, this study tries to come up with other and better solutions.
