Green light for wellhead removal ops at Australian oil field
What happened
Jadestone received NOPSEMA approval to remove three Montara wellheads offshore Australia. The plan uses one vessel, includes ROV ‘as found’ and ‘as left’ surveys and allows an operational window for mobilisation, removal and demobilisation plus onshore disposal after recovery. Procurement should watch vessel/ROV availability, port handling and waste‑facility timelines as the immediate operational constraints
Buyer takeaway
Treat this as a real, bounded decommissioning demand: the single‑vessel profile and explicit survey/disposal steps make mobilisation and waste handling the procurement focus
Cost / money
Concentrated vessel/ROV and disposal requirements increase near-term logistics and port-handling exposure that can attract premium fees if not locked down
Supplier / commercial
Vessel and ROV contractors can press for narrow bid validity, mobilisation SLAs and explicit demobilisation pricing given the compact campaign profile
Safety / operations
ROV and recovery tasks plus marine growth removal create HSE staging needs; incomplete staging or missing spare parts risks offshore rework
What to watch
Watch supplier timelines for vessel/ROV mobilisation and the nominated receiving port’s capacity to accept and process recovered wellheads
Key facts
- Three Montara wellheads approved for removal
- One vessel required for recovery operations
- Allowance provided per wellhead campaign to cover mobilisation, surveys, removal and demobili
- Dismantling and disposal due to complete within 12 months after arrival at receiving port

The EP underlines that the wellhead removal will be subject to the availability of a suitable vessel, and whenever feasible, will be a vessel of opportunity mobilizing to the Montara field for other activities. As a result, the exact timing of the wellhead removal is unknown

The accepted EP, which provides for the removal of Montara-1, 2, and 3 wellheads, includes remote operated vehicle (ROV) activities such as ‘as found’ and ‘as left’ surveys, marine growth removal, and wellhead area preparation
