Marine dual fuel engine control system modelling and safety implications analysis

Research output: Chapter in Book/Report/Conference proceedingConference contribution book

Abstract

The present study focuses on the modelling of a marine dual fuel engine and its control system with an aim to study the engine response at transient conditions and identify and discuss potential safety implications. This investigation is based on an integrated engine model developed in GT-ISE™ software, capable of predicting the steady state performance as well as the transient response of the engine. This model includes the appropriate modules for realising the functional modelling of the engine control system to implement the ordered engine load changes as well as switching the engine operating mode. The developed model is validated against available published data. Subsequently, two test cases with fuel changes, from gas to diesel and diesel to gas were simulated and the derived results were analysed for investigating the safety implications that may arise during operation. The results showed that the matching of the engine and the turbocharger as well as the exhaust gas waste gate control are critical factors for ensuring compressor surge free operation during fuel changes.
