Project Profile
Value: US$761 million
Location: Jurong Island’s Banyan Basin,
Storage capacity: 1.47 million cu metres
Send out capacity: 33.9 billion cubic metres of gas per year
Jurong Rock Cavern, South-east Asia’s first underground rock cavern for oil storage, with its two access shafts almost completed, will begin its first phase of proper construction at the end of 2012, with the first two caverns providing 480,000 cu metres of storage. The project is estimated to cost around US$761 million. JRC is located more than 100 metres below Jurong Island’s Banyan Basin and it will provide safe and secure storage for liquid hydrocarbons such as crude oil, condensate, naphtha and gasoil. Locating the JRC just beneath Jurong Island will add more infrastructural support to the major chemical companies operating there such as Chevron Philips, ExxonMobil and Shell. Phase 1 of the project will free up about 60ha of usable land above ground and it will create 1.47 million cu metres of storage space, when completed by 2014.
The cavern itself will be up to 27 metres high - equivalent to a nine-storey building. This first phase will consist of 8 kilometres of tunnels and five caverns housing a total of nine storage galleries. The caverns will be built using a technique that drills and blasts sedimentary rock and for greater stability, the inner wall will be lined with rock bolts. A planned phase 2 of the project will double JRC’s storage capacity. JTC Corporation awarded GK-JCPL Consortium, a Jurong International partnership with French engineering firm Geostock, the contract to provide basic engineering design and construction management services for the caverns and associated facilities. Jurong International is also previously responsible for many of the heavy infrastructure and engineering projects associated with Jurong Island including its initial formation via reclamation and amalgamation of seven islands. EPC design and build contract for the proposed jetty work to Phase 1 Jurong Rock Cavern was awarded to Antara Koh Pte Ltd by the main contractor Hyundai Engineering & Construction Co. Ltd. The package includes dredging, soil investigations, design and construction of the Jetty. The contract duration was 16 months.
