Jurong Rock Caverns
Jurong Rock Caverns (JRC), South-east Asia’s first underground rock cavern for oil storage, provides 480,000 cu metres of storage space.
JRC is located more than 100 metres below Jurong Island’s Banyan Basin and provides safe and secure storage for liquid hydrocarbons such as crude oil, condensate, naphtha and gasoil. Locating the JRC just beneath Jurong Island has added more infrastructural support to the major chemical companies operating there such as Chevron Philips, ExxonMobil and Shell.
Phase 1 of the project freed up about 60ha of usable land above ground and created 1.47 million cu metres of storage space, equivalent to 580 Olympic-sized pools. Completed in 2014, the cavern itself will be up to 27 m high – equivalent to a nine-storey building. 8 km of tunnels and five caverns housing a total of nine storage galleries were built using a technique that drilled and blasted sedimentary rocks and for greater stability, the inner walls were lined with rock bolts.
A planned phase 2 of the project will double JRC’s storage capacity. GK-JCPL Consortium, a Surbana Jurong with French engineering firm Geostock, was previously awarded the contract to provide basic engineering design and construction management services for the caverns and associated facilities.
