Technology Innovation for Defence-platform Energy-efficiency Project (TIDE): energy-efficient design approaches for next-generation warships

Abstract

This paper contributes to the Technology Innovation for Defence-platform Energy-efficiency (TIDE) project, a collaborative initiative between BAE Systems and the Universities of Southampton and Strathclyde, aimed at enhancing the energy performance of future naval platforms. Within the hydrodynamic research stream, this study presents experimental and numerical investigations focused on reducing propulsion energy demands. Key contributions include stern foil experiments for wave energy interaction, resistance-based analysis supporting alternative RPM control strategies, and a voyage energy simulation framework using Simulink to evaluate full-mission power demand. Combined, these efforts support TIDE’s overarching objectives of improving ship-level energy efficiency by 5–25% and reducing through-life energy costs through integrated design and operational solutions. The results highlight the potential of combining low-order models, hybrid propulsion analysis, and flow control technologies to support energy-aware control and planning strategies. While ongoing, this work establishes a foundation for next-generation warship design aligned with sustainability and operational resilience goals.
