TMT and Sapura Energy Australia successfully completed phase 1 of a historic offshore decommissioning campaign.
The challenge: Protect the environment by suspending legacy oil wells
When our client set out to secure seven legacy oil wells off the Australian coast, the scale and sensitivity of the task demanded more than just capable technology. It called for a partner with proven capabilities, deep offshore expertise, and an unwavering commitment to safety and sustainability.
TMT solved it.
Partnering with Sapura Energy Australia, TMT delivered Australia’s largest-ever Riserless Light Well Intervention (RLWI) decommissioning campaign – a 156-day offshore operation that not only met but exceeded environmental and technical expectations.
What made this project exceptional?
- 156 continuous days offshore.
- 7 wells safely secured with temporary downhole barriers.
- Largest LWI decommissioning project in Australian history.
- TMT’s biggest project of the year.
- From start to finish, this was a landmark achievement that raised the bar for what’s possible in offshore decommissioning.

TMT’s role: technically excellent, from concept to operations
TMT supplied our proprietary Riserless Light Well Intervention system and operated dual Remotely Operated Vehicles (ROVs) onboard the DSV Sapura Constructor. But tools alone don’t drive results.
What set phase 1 of this project apart was TMT’s highly skilled specialists who know what works in the field, and how to make it happen under pressure.
Our contributions included:
- End-to-end engineering support through all operational phases.
- Deployment and management of twin ROV systems.
- High-reliability LWI tools designed for extreme offshore conditions.
From initial planning, TMT worked concept to operations, ensuring nothing was left to chance.
It was a people-powered success
Behind every system was a team driven by belief, ingenuity, and grit.
TMT’s entire organisation came together:
- Finance ensured seamless vendor coordination.
- Logistics secured safe and timely movement of critical equipment.
- ERP systems held strong under 24/7 pressure.
- Our Malaysian team supplied key personnel to support frontline roles.
- Staff across the business volunteered their time after hours to keep operations moving.
Despite a lean headcount, our team proved what’s possible when you’re quick and nimble, focused, and all-in.
Navigating complexity with confidence
Every decommissioning project brings unique challenges, and this was no exception. But where others might stall, TMT leans in. Our response was rooted in:
- Deep domain knowledge.
- Strong cross-partner relationships.
- A culture of high-performance execution.
- A shared belief that solving hard problems is what we do best.
Leaving the ocean better than we found it
This project isn’t just about making old infrastructure safe – it’s about protecting the marine environment and advancing sustainable decommissioning practices.
By using Australian-developed technology, TMT is helping safeguard the marine environment and reinforcing Australia’s role as a leader in responsible offshore energy practices.
The result? A new benchmark for decommissioning in Australia
Phase 1 of this campaign showed what’s possible when technology, teamwork, and trust come together. It set new standards for complexity, collaboration, and care – and solidified TMT’s place as a leader in the offshore energy space.
In moments where technical certainty and environmental care must go hand-in-hand, TMT solves.
