Offshore projects: Vår Energi and OneSubsea shift to early engagement and standardization

Vår Energi partnered with OneSubsea to overhaul its project delivery approach, emphasizing early involvement, integrated teams and standard solutions to reduce delays and improve predictability, leading to faster project completion.

Key Highlights

  • Early involvement of suppliers helps assess costs, risks and feasibility upfront, enabling better decision-making and project sanctioning.
  • Integrated teams foster faster issue resolution and stronger ownership, accelerating project progress through shared information and collaboration.
  • Aligning execution across the full chain allows for earlier manufacturing and fewer delays caused by bespoke components.
  • The partnership approach has already resulted in over 20 early-phase studies, with multiple projects underway and plans for five more by 2026.

In 2022, Vår Energi set a target for its future developments: deliver more projects and deliver them faster. Meeting that ambition required early visibility into cost, schedule and feasibility, right when key decisions were being made. However, this can be difficult, because in the traditional contracting model, scopes are fragmented and multiple handovers occur, slowing decisions and adding complexity.

“What we see is that the process gets cluttered,” said Frode Sivertsen, vice president of project development at Vår Energi. “There are too many interfaces and too much back and forth before we see real progress, and that’s what creates delays and extra work.”

Suppliers like OneSubsea face the same issues. Repeated bidding cycles add uncertainty, and each new project starts with a new team and new assumptions, making alignment more difficult.

In short, the traditional model disrupts continuity and hinders delivery.

The partnership approach

To address these challenges, Vår Energi chose to partner with OneSubsea as its primary supplier. Instead of restarting with every new project, the two companies now work through an integrated setup that brings the supplier in earlier and removes unnecessary steps.

This approach is not new; it’s proven. For nearly a decade, OneSubsea has used a similar model with Aker BP. The Subsea Alliance between Aker BP, OneSubsea and Subsea7 has demonstrated that early engagement and standardization improve speed, efficiency and predictability.

“Over the years, we’ve seen that projects are not just moving faster, they’re also more stable,” said OneSubsea Project Director Kai Erlend Aas, who has managed the Subsea Alliance for OneSubsea from the start. “With early commitment, we avoid the repeated resets that can otherwise hold projects back.”

The partnership between OneSubsea and Vår Energi is built on four principles:

1) Start early and stay connected 

OneSubsea joins the team well ahead of the first decision gate. Cost, schedule, risk and feasibility are assessed together, giving Vår Energi a clearer picture early on—improving the chances of a project being sanctioned—and enabling a leaner organization.

2) Work as one team

Integrated teams collaborate from the start, helping issues surface sooner and solving them faster. This camaraderie also builds stronger ownership, creating an “all for one and one for all” dynamic.

“The real change is how quickly teams start moving once they start sharing information,” said Theis Stray-Pedersen, OneSubsea senior project manager. “When people see the same picture at the same time, the pace picks up naturally, and we are all delivering together.”

3) Use proven standard solutions

Vår Energi bases new developments on the NCS2017 standard subsea production system (SPS) portfolio. Standard, pre-qualified equipment reduces engineering work, accelerates procurement and improves reliability. In addition, reusing the same building blocks across multiple projects strengthens consistency and creates scale benefits.

4) Align execution across the full chain

Standard equipment and familiar teams make each phase more efficient. Packages move to manufacturing earlier, and fewer bespoke components mean fewer delays.

Early gains and impact

Since adopting the model, more than 20 early-phase studies have been completed, the first full deployment is underway and five new projects are planned for 2026.

The "Balder Next - New Wells" project provides an early example. Vår Energi had set a schedule that many considered unrealistic, but through early commitment on equipment and standardized equipment, the joint team confirmed it was achievable.

“What the Balder Next - New Wells project has showed us is that the constraint wasn’t the schedule; it was the way we used to work,” Sivertsen said. “If the teams are aligned early, the path forward becomes much clearer.”

Is this approach competitive enough?

Some question whether a partnership model reduces competitiveness. Vår Energi takes a broader view: gains in speed, predictability and the likelihood of a project being sanctioned often outweigh any theoretical savings from repeated competitive studies and bids.

“Competitiveness is, of course, key, and we actively use benchmarks to ensure costs are at the right level,” Sivertsen said. “But if you only focus on achieving the lowest bid number, you miss the real value. This approach reduces uncertainty, and that’s what keeps projects moving instead of stalling.”

This collaborative approach also creates room for joint optimization and cost savings in offshore installations, drilling and life-of-field operations.

Conclusion

As expectations for predictable delivery grow, operators are rethinking how projects should be structured. OneSubsea’s experience with Aker BP and Vår Energi shows that a partnership model built on early engagement, integrated teams and standard solutions can meaningfully improve execution.

The approach requires trust and new ways of working, but the benefits are becoming clear across multiple developments.

“We’ve learned over the years that teams adapt quickly once they see the proof that the concept works. The approach removes noise from the process, and that gives everyone more time to focus on what actually moves the project,” Aas concluded.

For Vår Energi, partnership remains the most reliable path to delivering more projects, delivering them faster and reaching first oil earlier.
