Project Background

The Tuas Terminal Phase 1 project is large in scope, and entails the construction of a new port terminal with 20 deep-water berths having a total capacity of 20 million twenty-foot equivalent units (TEUs) per annum. The Joint Venture will be responsible for the erection of an 8.6-kilometre quay wall and its foundation, the dredging of the fairway and basins, as well as the reclamation of 294 hectares of new land. This major project is expected to complete within six years (by 2020).

To achieve this, more than 80 million cubic metres of reclamation fill will be used comprising dredged materials from the seabed, excavated materials from other land-based projects and sea sand. Laid with a foundation of 222 caissons each weighing about 15,000 tonnes, the quay wall will be fabricated at a temporary yard on site and transported using a newly constructed 20,000-tonne floating dock vessel. One of DEME’s most powerful rock cutter suction dredgers and a trailer suction dredger will also be deployed for the dredging works. The construction activities shall be executed according to strict environmental requirements specified and with continuous environmental monitoring supervision by an independent environmental specialist appointed by MPA.
