PTT Exploration and Production (PTTEP) has completed what it says is Thailand’s first full reuse of a decommissioned wellhead platform, relocating and redeploying an entire offshore structure instead of dismantling it for scrap or parts.
A wellhead platform is a fixed offshore structure that supports wellhead equipment and connects oil and gas production wells with downstream processing facilities.
The company estimates that reusing one platform can cut emissions by around 3,270 tonnes of CO2 equivalent compared with building a new structure, mainly by avoiding new steel and equipment production.
Unlock the full article to explore three key takeaways:
- PTTEP's first full platform reuse cut construction time by 70% and costs by 35 to 50%, with plans to extend the approach to around 10 more platforms by 2029.
- More than 200 offshore fields in Southeast Asia are expected to cease production by 2030 at a projected cost of USD 30 billion to USD 100 billion, making asset reuse strategies increasingly relevant across the region.
- Thailand's decommissioning framework covers removal plans, cost estimates, and financial security, but contains no provision requiring operators to evaluate reuse before dismantling — a gap that more developed regimes such as the UK's explicitly address.
