Should the project be given the green light, it will see the construction of 32 underground caverns with each cavern having a 125,000 cubic metre storage capacity. The caverns, which will not be lined with steel or concrete - will be constructed 40 metres to 80 metres underground. Whilst no construction schedule has been drawn up yet, JTC admits that a 500,000 cubic metre cavern could take between two to three years to build.

JTC feels that the facility will enhance Singapore's position as a regional oil trading and storage hub and free-up necessary land that could be used to house the country's growing population. However, according to JTC, final decision on the project will only be made at the end of the year following the completion of a feasibility study on the project.
