SJ’s Coastal Engineering was appointed by Maritime and Port Authority of Singapore (MPA) in 2012 when the Tuas Terminal Phase 1 (TTP1) reclamation project was first conceptualised. The team worked on the planning of the new port, envisioning the type of future vessels that it would have to cater for. The planning scope included the infrastructure services at the new port, the reclamation scheme and the ground improvement required by the port operators.
Tuas Terminal is an engineering feat with many innovative features that increase productivity, optimise land use, improve safety and security, and enhance sustainability. For instance, the design adopts the concept of circular economy through the massive re-use of dredged and excavated materials as reclamation fill and caisson infill materials which resulted in significant material cost savings. The use of innovative caisson design for the wharf structures helped to improve productivity and quality as the caissons are of standard sizes and prefabricated in a controlled environment on site. The finger-piers with caisson quay walls were adopted to maximise the limited land and sea space. Coupled with long linear berths and a design depth of -23m at CD, Tuas Terminal will be able to accommodate mega container ships exceeding 450m in length.
In 2015, SJ’s Coastal Engineering won a separate contract by MPA for the construction supervision, project management and contract administration of TTP1. The team oversaw the creation of 8.6km of caissons wharf; reclamation using almost 88 mil m3 of material; dredging of navigational channel and wharf basin, and soil improving 414ha of land for container port use. When operational, Tuas Terminal Phase 1 will have a capacity of 20 mil TEUs.
