Turning ideas into action

Anasuria, Helix and Exceed: Proving that crew engagement drives measurable savings

November 26, 2025

The Anasuria campaign was short, focused, and practical, a 13-day well intervention designed to test how quickly crew-led initiatives can deliver measurable gains. Working with Anasuria Operating Company, Exceed Energy, and Helix Energy Solutions, Stepwise deployed SmartSaver, a low-cost, on-board programme that turns crew observations into structured energy actions. Within days, teams were identifying idle loads, improving power management, and sharing verified savings across shifts. The result demonstrated that even in a brief campaign, structured awareness and shared accountability can create lasting improvements in efficiency, fuel use, and emissions performance.

Key figures

Measured results from a disciplined, data-driven campaign.

The Anasuria campaign demonstrated how disciplined collaboration and clear data deliver measurable gains in operational efficiency. Over a 13 day programme, the team maintained full safety and transparency while embedding the Stepwise SmartSaver Energy Reduction Initiative (ERI) to drive crew-led actions. The campaign achieved a 22.3% reduction in daily fuel intensity compared to the previous year, supported by 36 logged SmartSaver ideas and engagement across six departments. Total emissions recorded were 582.6 CO2te. Analysis also identified potential for a further 8–10% reduction through future ERIs. This short, focused intervention proved that when insight are structured and shared, efficiency and engagement advance together: measurable, repeatable, and ready to scale.

Fuel cost and CO2 savings are annualised. * Performance metrics exclude Non-Productive Time (NPT) and Waiting on Weather (WOW) to ensure results reflect controllable operational efficiency. All totals and averages are calculated over the active operational phase only, following the Stepwise continuous improvement methodology. ** Total savings potential includes both implemented and recommended ERIs annualised.*** The operator was not exposed to a CO2 tax, as the campaign was conducted on the UK Continental Shelf under the UK Emissions Trading Scheme (UK ETS). A $100 per CO2te benchmark is applied for reference, reflecting typical market values in major trading systems. Cost benchmarks: Fuel cost saved calculated using $1,000 per m³ for marine fuel.

Total rig fuel cost per wellbore in USD (Planned vs Actual)
Across the five-well campaign, total planned fuel costs were $11.2 million compared to an actual spend of $10.19 million, a saving of approximately $1 million, representing a 9% improvement in overall fuel efficiency and a clear demonstration of measurable well economics in action. Where overrun occured, significant WOW was accountable.

How savings were made

Crew-led efficiency in practice.

SmartSaver embedded a culture of efficiency by giving crews the structure to turn insight into action. Five-minute energy huddles replaced informal conversations, creating disciplined follow-up. Observation cards logged small, repeatable actions: lights switched off in empty spaces, idle equipment isolated, fans and hot-water urns rationalised, and standby loads reduced. Bridge officers applied Green-DP planning before engagement, balancing safety with energy control. The result, lower idle power, tighter handovers, and a measurable 22% improvement in daily fuel use versus the previous baseline.

In this short video, listen to Tom Reeve, Wells Manager at Anasuria, explains how this took shape offshore and how the crews brought these improvements to life.

Total annualised savings potential: ≈ $3.4 – $3.5M

Savings from implemented ERIs.

Total savings (annualised): ≈ $1.7M.

Learnings and transferable insights for future campaigns.

  • Behavioural and cultural improvements: SmartSaver daily energy huddles, observation cards, simple baselines & targets
  • Incentives and recognition for crew engagement
  • Monitoring and feedback – track and display savings progress and encourage reporting of energy waste
  • Engineering/infrastructure solution improvements:
    • Propeller/thruster polishing prior to start
    • Hull cleaning (under water area incl. tunnels/moonpool)
    • Optimised DP operations (heading plans, engine/thruster set points, Green-DP windows)
    • DP weather prediction integrated with planning and WSOG (eWSOG/Eco Advisor or equivalent)
* Assumptions: Fuel cost savings are calculated using a benchmark of $1,000 per m³ for marine gas oil (MGO), reflecting a mid-range value for North Sea offshore operations in 2025. Actual savings may vary depending on fuel contract pricing and load profiles.
The goal

Collaboration made measurable.

To prove that disciplined collaboration, not just reporting, drives measurable progress. The Anasuria campaign aimed to maintain performance, reduce avoidable fuel use, and simplify compliance through shared, transparent data. The outcome directly supports NSTA Stewardship Expectation 9: Collaborative engagement, open data, and continual improvement.

The approach

A structured rhythm for continuous improvement.

Stepwise applied its One-Team Collaboration Model, uniting operator, well management, and vessel crew under a single performance baseline. The process followed the Stepwise framework – What → So What → Now What, capturing what occurred, contextualising why, and guiding what to do next.

Key enablers included:

  • Unified fuel and load tracking shared daily with the bridge and engine room
  • Observation-led insight sessions turning data into decisions
  • Transparent reporting aligned with ISO 14064 and NSTA ESG guidelines
  • Continuous learning reviews for follow-on wells

This structured rhythm of awareness, action, and verification delivered both operational discipline and lasting behaviour change.

Testimonials

Stepwise SmartSaver complemented the way we work at AOC. Observation cards and short briefs made it easy for supervisors to reinforce actions. The tone stayed positive, with safety first and efficiency always in view. We’re looking forward to the next one.
