Ship engine maintenance and diagnostics

Model Based Development (MBD) simulation is used to significantly shorten the development time of ship engine control systems including testing, evaluation and calibration.

Faster than real-time engine plant models with predictive combustion, kinetics and emission sub-models are used within Model-in-the-Loop (MiL), Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL) applications to accelerate engine system development, complementing conventional methodologies. Control logic and the engine plant model are developed in software with MATLAB/Simulink before application to the target hardware, for subsequent maintenance and diagnostics of the engine.

Our simulation toolset provides a number of packages that can be used within MBD for maritime applications.

IGNITE is a complete physics-based hybrid simulation package with a library of building blocks, that the user can quickly and accurately model complete maritime propulsion systems as part of MBD.

WAVE is a 1D Computational Fluid Dynamics (CFD) tool that provides ICE data to the system model across a range of operating scenarios with predictive combustion models for maritime applications, including biofuel and methanol carbon-neutral fuels, as well as ammonia and hydrogen zero-carbon fuels.

WAVE-RT is a tool that replaces the need for a high number of physical test points collected over many hours or days to carry out engine calibration. It uses measured data to a limited extent to tune a digital twin which generates a data set of calibration simulation results which are used for calibration, speeding up the process and reducing costs. Replacing the majority of measured data with simulated results saves time and money whilst being fast and accurate, delivering results in real-time with no loss in model fidelity or complexity.
