The 5-10% Illusion: Accepting the Complexity Behind Fuel Saving Claims
Across the shipping industry, claims of achieving 5-10% in fuel savings from various digital and physical solutions are widely stated; however, obtaining credible proof remains a challenge and is rarely part of the story.
As ships are bespoke assets operating in highly variable environments, small efficiency improvements are easily lost in “measurement noise” caused by weather, hull fouling, sensor drift, route variations, and cargo differences. While these 5-10% gains carry unprecedented economic and environmental weight, the repeated reliance on marketing hype over verified proof has created a severe credibility problem.
This erosion of trust has cascading effects: it fuels scepticism, slows the adoption of genuinely effective technologies, misallocates capital, and ultimately undermines the industry’s collective drive toward decarbonisation.
“The 5-10% problem is less about whether savings exist and more about whether they can be credibly measured and verified.”
What You Will Discover in This Report:
- Diagnosing the Credibility Gap: Understand the commercial pressures, behavioural factors, and technical complexities that drive vendors to overstate benefits and selectively report data.
- The Measurement Shortfall: An in-depth evaluation of why current measurement methods, including Computational Fluid Dynamics (CFD), model tank tests, sea trials, and the ISO 19030 standard, cannot reliably verify small efficiency gains in isolation.
- The Cost of Ambiguity: Discover how a single change in a charterparty’s weather terminology can shift a vessel’s measured daily fuel consumption by almost 50%, equating to a US $5,000 per day difference in bunker costs purely from contractual language.
- Unlocking True Value: Why the industry must shift from simply filtering out bad weather data to accurately normalising data for real-world conditions.
- A 5-Step Validation Framework: Actionable guidance on how to move from marketing claims to measurement discipline by defining clear baselines, building validation chains, and leveraging high-quality sensor data.
- Strategic Recommendations: Core steps to align the maritime industry, including the need for vendors to publish uncertainty ranges alongside efficiency claims and the critical importance of independent, third-party verification.
