Helix Energy To Decommission Wells Offshore New Zealand


Houston-based offshore services firm Helix Energy Solutions has won a 5-well complete abandonment project by New Zealand’s Ministry of Business, Innovation & Employment (MBIE).

The contract with MBIE is the second recent award for Helix in the Asia Pacific region, following the award of Cooper Energy BMG wells abandonment in Australia’s Bass Strait.

Helix said that the work would be performed using the Helix Q7000 and 10K Intervention Riser System. The Q7000 is expected to mobilize late 2022 to the Tui Field, offshore New Plymouth, and perform the work in three phases, including well abandonment, recovery of XTs, and wellhead severance and recovery. Excluding mobilization, the project is anticipated to last approximately 60 days.

“This award, coming on the heels of our award with Cooper Energy, shows that an integrated vessel package such as the Q7000 can address a wide range of subsea decommissioning challenges. With Schlumberger, our partners in the Subsea Services Alliance, we provide a complete solution to complex decommissioning scopes. As we commence this project, we look forward to working with tangata whenua, MBIE, and the wider community to protect and restore the mana of this location,” David Carr, Senior Vice President for International for Helix Well Ops, said.

“We are thrilled to be awarded our first-ever decommissioning project offshore New Zealand,” stated Scotty Sparks, Helix’s Executive Vice President and COO.

“We are industry leaders and are excited to continue expanding our service offerings and global operational footprint into the APAC region, helping our clients navigate energy transition, optimize subsea infrastructure, and maximize their economic returns,” he added.

“Helix was awarded the contract after a competitive procurement process to select a supplier that met MBIE’s objectives of a robust technical solution, flexibility in timing, competitive pricing, and a commitment to working with iwi and local stakeholders,” said MBIE Tui Project director Lloyd Williams.

“Helix is widely recognized internationally as one of the largest and most capable contractors for well intervention and abandonment, and we are looking forward to working with them to complete the final phase of the decommissioning. Helix’s proposed vessel to carry out the work, the Q7000, is a state-of-the-art unit which is optimized for well decommissioning and features specialized equipment required to complete the work safely and efficiently,” Williams claimed.

The Q7000 can execute well intervention and decommissioning operations in water depths ranging from 280 to 9,850 feet. With its open deck plan and tri-axial configuration, the Q7000 is capable of a wide range of production enhancement operations like well clean-up and field development support.

The vessel is optimized for well decommissioning, including suspension, tubing removal, tree recovery, and seafloor clearance.

The Q7000 features Schlumberger equipment as part of the joint Subsea Services Alliance, providing integrated subsea well services including coiled tubing, slickline, e-line, and cementing services.
