What we do


The Government of Singapore aims to consolidate its world-class container port facilities at Tuas, starting in 2030. New technology is being introduced at the greenfield site to create a hypermodern, innovative and largely automated logistics hub. The consolidation will also free up existing port facilities near the city centre for future urban redevelopment.

The Tuas Terminal Project, of which Phase 1 is a crucial milestone, will ensure that Singapore’s leading global hub port continues to have sufficient capacity to meet industry demand in the long term.


This huge project entails the construction of a new port terminal with over 20 deep-water berths, representing a total capacity of 20 million twenty-foot equivalent units (TEU) per annum. It involves the erection of an 8.6 km quay wall including its foundation, the dredging of the fairway and basins, as well as the reclamation of 294 ha of new land.

To achieve this, DEME has to use more than 80 million of reclamation fill which will mainly comprise dredged materials from the seabed, excavated materials from other land-based projects and sand imported from distant sources.

Comprising 222 caissons each weighing about 15,000 tonnes, the quay wall was fabricated at a temporary yard on site and was transported using a 20,000-tonne floating dock vessel. The scour protection in front of the caissons was partly designed by the contractor and consisted of 8 m x 8 m concrete slabs.

One of DEME’s most powerful rock cutter suction dredgers (CSD) and a spread of trailer suction dredgers (TSHD) were also deployed for the dredging works. A limited part of the dredging works involved rock which had to be blasted using a specialised pontoon before being brought ashore by our CSD. After being brought ashore, the rock was crushed and reused as fill in the reclamation. Other parts of our scope included the design (in part) and placement of scour protection, soil investigation & compaction, the design and execution of soil improvement techniques, the installation of vertical drains and long distance sand supply.

The construction activities were all executed according to the strict environmental requirements in place, and subject to continuous environmental monitoring supervision by an independent environmental specialist appointed by the Maritime and Port Authority of Singapore (MPA).
