Reclamation works for Phase 1 on track to be completed by 2021
Mr Khaw Boon Wan, Coordinating Minister for Infrastructure and Minister for Transport, witnessed the installation of the 221st and final caisson for Tuas Terminal Phase 1 reclamation today. Commenced in 2015, Phase 1 reclamation works are three-quarters completed and on schedule to be fully completed in 2021. PSA Corporation will then begin terminal development of deep-water berths that are able to handle about 20 million twenty-foot equivalent units (TEUs) per annum.
2 The use of caissons in Phase 1 is a safer and more efficient method of reclamation compared to traditional methods such as piling. The caissons used for Tuas Terminal’s construction are one of the largest in the world. Pre-fabricated onsite, the caissons each weighs 15,000 tonnes and measures 40m in length, 28m in width and 28m in height – as tall as a 10-storey building.
3 “Our Mega Port project at Tuas will transform our port operation, to position ourselves for the future. The project itself is a mega infrastructure project, and hence, an opportunity to transform our construction and reclamation industry. We have been reclaiming from the sea since independence. But the Tuas reclamation project is not more of the same; it applies complex state-of-the-art engineering expertise, using caissons for higher efficiency and safety. Each caisson weighs 15,000 tonnes and is a 10-storey giant! Today, we install the 221st caisson; it is the final caisson for Phase 1 of the Tuas Mega Port. I congratulate the engineering team. I commend their spirit of innovation,” said Mr Khaw.
4 Together with Dredging International Asia Pacific - Daelim Joint Venture and Surbana Jurong, the Maritime and Port Authority of Singapore (MPA) has adopted innovative solutions, ranging from the pre-installation of geotextiles on caissons on land instead of at sea, and the use of artificial intelligence to the use of drones for site survey and progress monitoring. In particular, there are two innovations, which have pushed the frontiers of engineering:
(a) TEMAROCK. TEMAROCK is a next generation all-in-one rock mound construction vessel. The conventional process of rock mound construction requires multiple vessels for rock laying and compaction, one survey vessel to facilitate operation, and is supported by divers. TEMAROCK automates these tasks, eliminating the need for multiple vessels or divers’ assistance. This enhances efficiency and safety.
(b) Automatic Rebar Machine using Robotics System (ARMS). ARMS automates the bending and cutting of reinforcement steel bars (or rebars, which are used to strengthen concrete) to the desired design, and then transfers them onto the stacking area. The conventional practice requires workers to handle the rebar manually, which exposes them to mechanical hazards when they operate the rebar cutting and bar bending machines.
5 Tuas Terminal will open progressively from 2021. When fully completed in 2040, it will consolidate all port operations in a single location and be capable of handling up to 65 million TEUs per annum.
