Your free guide to the rules of offshore decommissioning in Commonwealth waters, from international obligations to title surrender.

Australia's decommissioning activity is accelerating, but the rules were written for exploration and production. This 20-page briefing, adapted from CODA's national regulatory mapping study, shows you which laws apply, which approvals you need, and how long they take.

Inside you'll find:

1. The four layers of regulation and where the 3 nm line matters
2. The three documents NOPSEMA must accept before work starts
3. What it takes to leave infrastructure in place
4. Title surrender, trailing liability and a permit timeline
   

From Quayside to Final Disposal: Waste, Ports and State Regulation in Australian Oil and Gas Decommissioning

Understand the regulatory requirements, approval timelines and waste management challenges that shape offshore decommissioning in Australia, with a focused look at Western Australia.

What happens when decommissioned offshore infrastructure reaches shore? From hazardous waste classification and port permits to interstate transport and final disposal, every stage introduces new regulatory requirements that can affect project timelines, costs and execution.

This free industry report, adapted from the Centre of Decommissioning Australia (CODA)'s public regulatory mapping study, provides a focused briefing on the onshore regulations governing oil and gas decommissioning across Australia.

What You'll Discover

Navigate Australia's regulatory landscape: Understand the key Commonwealth, State and Territory requirements governing waste, transport, recycling and disposal.

Plan for Western Australia's approval timelines: Explore key permits, licensing requirements and lead times, including approvals that may need to be initiated 12 months or more before decommissioning begins.

Identify hazardous materials and disposal pathways: Learn how NORM, mercury, asbestos, PFAS and other materials can affect handling, transport and disposal options.

Understand port and logistics requirements: Review the permits and regulatory considerations involved in moving decommissioned structures and hazardous waste through Australian ports.

Compare waste destinations and transport requirements: Explore the regulatory considerations for interstate waste movements, overseas exports and Australia's hazardous waste disposal facilities.

Build a more effective decommissioning roadmap: Identify practical steps for planning waste strategies, coordinating regulators and accounting for long approval lead times.

Reuse Before Removal: What the Gulf of Thailand reveals about the next phase of offshore decommissioning

In mid-2026, Chevron and PTTEP each relocated and redeployed an entire wellhead platform in the Gulf of Thailand. This free white paper explains what it means for decommissioning across Asia-Pacific.

Inside, you'll find:

• What happened at Chevron's Chaba B and PTTEP's Jakrawan K, and how both projects built on nearly a decade of topside reuse
• The three types of "reuse" (topside reuse, total reuse and reefing) and why the difference matters for pricing, permitting and bidding
• Why the business case is about speed and cost, not only carbon, including PTTEP's estimate of 6 months to install versus about 20 for a new build
• Where reuse works best, and why nearby demand for the asset matters
• Why removal still isn't going away, with lessons from the Erawan field handover
• What reuse asks of the supply chain, from structural assessment to heavy lift and regulatory approvals
• What Australia and wider APAC can learn, including Australia's A$43.6 billion decommissioning liability estimate
  

The Conversation Has Moved from "When?" to "How?"

Ageing offshore platforms across Australia, Malaysia, Thailand, Indonesia and beyond are moving from production into retirement. Northern Endeavour's Phase 3A tender is out. PETRONAS is running its largest coordinated retirement program to date, covering 31 platforms. Operators are looking beyond removal toward reuse, reefing and recycling. But vessels are scarce, specialist skills are thin, and recycling capacity is lagging behind. This report looks at whether the region is ready, and what needs to happen next.

What You'll Learn:

• The scale of the challenge. A market-by-market view of ageing platforms across Indonesia, Malaysia, Thailand, Brunei and Australia. It also explains why Australia carries the biggest liability despite having fewer assets.
• Three regulators, one region. How NOPSEMA, MPM/PETRONAS and the UK's NSTA approach compliance. It also makes the case for replacing Australia's three separate approvals with a single integrated plan.
• Design it, don't retrofit it. ADNOC's lifecycle approach to well integrity, which builds P&A into well design from day one.
• From removal to reuse. Case studies from PETRONAS, PTTEP and Chevron Thailand. One is a platform reuse that cut execution time from around 20 months to 6 and construction costs by 35–50%.
• What APAC can learn. Benchmarks from Norway, the UK and Brazil on regulation, cost discipline and deepwater scale.
• The supply chain question. Where vessels, workforce and waste capacity fall short, and why visibility is the missing layer.
• Five priorities for what comes next. A practical agenda for operators, regulators and the supply chain.

"Essentially, we needed everything. We needed the skills, the knowledge, the experience, the technologies, and the vessels." - Dr Francis Norman, CEO & Managing Director, CODA
