Client context
A retrofit technology provider supplying energy-saving devices (ESDs) required independent technical substantiation to convince owners and charterers—beyond vendor marketing claims.
Problem
Owners sceptical of claimed fuel savings
Concerns over structural integrity, fatigue, and hydrodynamic side-effects
Need for third-party validation to support commercial guarantees
What we did
Coupled CFD + FEA assessment of retrofit devices across realistic sea states
Quantified net fuel benefit after accounting for drag, vibration, and structural penalties
Provided load envelopes and fatigue life predictions suitable for class discussion
Produced a neutral, auditable technical dossier
Outcome
Confirmed net 3–5% efficiency gain for selected duty cycles
Identified installation conditions where benefits would not materialise—avoiding mis-selling
Enabled supplier to offer performance-linked contracts with confidence
Strengthened acceptance by technically sophisticated operators
What's in it for you
Complements digital performance monitoring with ground-truth engineering evidence
Reduces noise in post-retrofit performance data
Creates cleaner signals for AI models tracking degradation, benefit decay, and ROI
