RGP2 — Orebody 18 (OB18)
Approved 25 October 2004
Portfolio window: 2002 (early RGP2 study) → ~2031 (Western Ridge greenfield first ore) · ~29 years of FEL → execution
The full WAIO portfolio view: the back-to-back Rapid Growth Projects (RGP2 OB18, RGP3 Area C, RGP4 Jimblebar/Newman Hub, RGP5 Yandi, RGP6 standalone Jimblebar), the JBx completion of the Jimblebar Hub (3rd primary crusher, ~2017), then the post-RGP "sustaining-capital" era — South Flank, the Western Ridge Crusher, the Jimblebar Optimisation program and the broader Western Ridge greenfield. Each card links to the original public announcement or regulatory filing.
The Rapid Growth Projects were not delivered by BHP in isolation — they were executed through two successive EPCM joint ventures between Fluor and Sinclair Knight Merz (SKM):
The continuity of an integrated EPCM team across all five RGPs — same engineering standards, same delivery model, same key personnel rolling between projects — is one of the structural reasons the RGP portfolio largely landed on time and on budget.
Each row tracks a project from early study (IPS / FEL1) through SPS (FEL2) and DPS (FEL3) to FID and execution. Only rough estimate on study durations have been used. Diamond ◆ marks FID; triangle ▲ marks first ore.
IPS / SPS / DPS durations are typical estimates for major Pilbara iron-ore expansions (BHP's stage-gate naming for FEL1 / FEL2 / FEL3). FID dates and first-ore targets are taken from BHP's public announcements.
Annual shipments from BHP's Western Australia Iron Ore business (100% basis). Markers show the fiscal year in which first ore was achieved for each major project. The flat plateau from ~FY15 onward reflects the end of the rapid-growth era and a deliberate shift to debottlenecking and sustaining capital. Its hard to underestimate the magnitude of the depletion of high grade ore bodies that will neccessitate nearly continuous ongoing projects unlocking new sources.
The popular narrative is that megaprojects always blow out on cost and schedule. The RGP portfolio is a counter-example: across five back-to-back expansions BHP largely delivered the sanctioned capex and first-ore dates, and South Flank — the next major mine — landed on schedule and on budget through COVID. Post-RGP projects in execution (WRC, JBx) are tracked here as they progress.
