Real-world performance data is reshaping understanding of passenger ship efficiency in heavy weather. By analysing full-scale operational measurements, researchers quantify the combined impact of wind and waves through an added-power methodology. New insights into aerodynamic drag on large topside structures could improve voyage planning, energy efficiency and design decisions globally.

New methods for evaluating ship performance in calm seas are improving the reliability of operational efficiency assessments. Using onboard monitoring data, resistance-based filtering, and slip-ratio correction techniques, the OCTARVIA approach isolates environmental influences and ageing effects. The validated methodology offers more accurate performance benchmarking and supports smarter fleet management decisions.

High-frequency operational data from modern LNG carriers is providing a clearer picture of real-world energy performance. Analysing DFDE propulsion systems across an active fleet, researchers identified operational patterns with unprecedented accuracy, reducing reliance on assumptions. The findings strengthen efficiency benchmarking, support optimisation strategies, and inform future vessel design decisions globally.

Full-scale trials of the Gate Rudder® reveal striking efficiency gains beyond conventional steering systems. Comparing sister ships and supported by CFD analysis, researchers identified fuel savings of up to 33% alongside manoeuvring benefits. The findings highlight how innovative rudder technology can significantly enhance vessel performance, sustainability, and operational competitiveness today.
