Jurong Island Westward Expansion


Following the successful four phases of reclamation, amalgamation and extension at Jurong Island (see here), the Jurong Town Corporation (JTC) expressed the need for further enlargement – driven by the requirement for ever expanding space at the booming petrochemical hub on the southwestern tip of Singapore.

The 32 km² Jurong Island is home of a cluster of global companies and oil majors, which are linked by a maze of enormous cylindrical tanks and a common pipeline service corridor, supplying products from one plant to another and servicing the industry with centrally provided steam and cooling water. Its refineries process a total of 1,3 million barrels of crude a day, and cracker plants produce speciality chemicals for global markets. Such an environment makes for just one challenge among many, when executing vast reclamation works.

An unusual level of co-ordination and planning is needed, as various contractors are busy on the same site at the same time, and production units sometimes begin operations before dredging or compacting is fully completed. The mere volume and the speed of unloading the vast amounts of sand from onboard the huge trailing hopper dredging vessels, requires an extensive experience. In addition, the reclamation campaign has to be executed in one of the busiest waters in the world and may not interfere with port activities which must go on in all circumstances.

Our solution

Dredging International’s subsidiary for the South-East Asia region (DIAP) was awarded a Design and Build contract for the westward extension of Jurong Island. The contract is executed in a joint venture with Starhigh Asia Pacific Pte Ltd. It also includes the realignment and deepening of the Temasek Fairway and the West Jurong Channel.

Beyond enlarging Jurong Island with 148 ha, various other works under this contract have to be carried out: sand bund construction; shore protection; deepening of shoreline; basin and channel realignment; soil improvement works; sand supply; re-use of marine dredged and land-based excavated material; construction of roads, drains and sewers; and preparation of a site for vacuum consolidation research.

The project is executed according to the provisions of an environmental assessment, and the requirements of the environmental monitoring and management program. Throughout the project, DIAP implements DEME’s high environmental and workplace safety standards.

The 1,02 billion SGD (plm 625 million euro) westward extension will be executed in three reclamation phases. Phase 1 has commenced by mid-December 2013 and Phase 2 will be finished by the end of 2017. Works for Phase 3 are to be completed by mid-August 2018.
