Construction and utilization of rock caverns in Singapore Part B: Development costs and utilization

Abstract

This part examines the potential uses of underground caverns such as shelter and recreational centre, water collection storage and treatment, sewage treatment, oil and gas storage, cold and dry storage, power station, underground pumped hydroelectric storage, military installation, and industrial waste repository in Singapore. It also presents the cost aspects of cavern-development. The costs of a crude oil storage and a warehouse scheme are closely examined and comparisons are made with above-ground development costs. The benefits of using underground caverns in Singapore are discussed.
