Crux has long been considered a likely second phase to Shell’s $16.6-billion (Aus.) Prelude development that has recently been brought on stream via the world’s largest FLNG vessel permanently moored in the field.
Initially the hook-up was not envisioned for many years, as a back-fill when production of gas from Prelude began to decline late next decade. A development plan recently submitted to Australia’s National Offshore Petroleum Safety & Management Authority (NOPSEMA), however, outlines the start of front-end engineering and design work for Crux later this year leading to a final investment decision in 2020.
