Green light for wellhead removal ops at Australian oil field
What happened
NOPSEMA approved Jadestone’s environment plan allowing Montara wellhead removal operations off Australia, which specifies ROV surveys, marine growth removal and wellhead recovery. The plan expects one vessel for recovery and allows a short onsite window per wellhead plus an overall mobilisation/demobilisation allowance; recovered wellheads will be dismantled and disposed of onshore within 12 months. Watch whether Jadestone confirms firm mobilisation dates and whether vessel availability drives quote validity or deposit requests
Buyer takeaway
Treat this as a real, near‑term mobilisation requirement in Australia and validate vessel and ROV availability before issuing or awarding scopes
Cost / money
Mobilisation, recovery and onshore disposal introduce pass‑through cost risk; unless contracts assign waste handling clearly, buyers will face cashflow and cost surprises
Supplier / commercial
Vessel owners and turnkey contractors can shorten bid validity or seek mobilisation deposits because the single‑vessel execution concentrates leverage
Safety / operations
Tight onsite allowances and ROV activities increase readiness needs for certified crews, lifting plans and onshore handling; verify before mobilisation
What to watch
Watch for suppliers shortening quote validity or asking for deposits once Jadestone issues firm mobilisation dates
Key facts
- One vessel required for wellhead recovery
- Approximate per‑well onsite allowance with a 14‑day mobilisation/demobilisation window included
- Onshore dismantling and disposal to be completed within 12 months of arrival at the receiving

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
