Maritime transport generates around 2.5% of global greenhouse gas emissions while enabling 80% of global trade. With IMO targets driving at least 5% of shipping toward zero emissions by 2030, the industry is rapidly transitioning to carbon-neutral and zero-carbon fuels such as methanol, biofuels, ammonia and hydrogen.

Realis Simulation supports this transition with advanced physics-based modelling tools for the design and optimisation of next-generation propulsion systems. Our solutions help engineers reduce risk, accelerate development and meet evolving emissions regulations.

Our maritime simulation capabilities include:

• Combustion and thermal modelling using high-fidelity CFD and FE methods for conventional and alternative fuels
• Emissions prediction using detailed chemical kinetics and 3D-CFD
• Lubricant oil consumption (LOC) analysis with advanced piston and oil transport modelling
• Hybrid and electrified propulsion simulation including battery and shore-powered systems
• Predictive maintenance and diagnostics using real-time capable engine models

By combining fluids dynamics, structural mechanics and systems engineering, Realis Simulation enables cleaner, more efficient maritime propulsion.
