DUQM Liquid Bulk Berths Project
Sultanate of Oman
Introduction
The Government of The Sultanate of Oman is in the process of developing Duqm town and the Port of Duqm, as a strategic dry dock, free trade zone, industrial and tourism destination. The Port of Duqm is seen as a catalyst for the development of the Al Wusta region. The Port and Dry Dock are being developed to increase the trade; i.e. cargo trans-shipments, ship repair, manufacturing and tourism. The site enjoys proximity to the busy regional sea-lanes of Oman’s coastal waters and is characterized by a friendly climate.
