Classification society American Bureau of Shipping (ABS) is using advanced modelling and simulation technologies to develop emergency response methods to assist ports and crew in responding to ammonia leaks or spills.
ABS informed it combined the modelling and simulation techniques with Computational Fluid Dynamics (CFD) to create a high-fidelity model designed to replicate ammonia dispersion patterns in the engine room.
It said: “Using this new model, ABS specialists studied the impact of various ventilation approaches on the behaviour of ammonia plumes resulting from leakages from the fuel lines, revealing optimum methods to vent the ammonia plume.”
According to ABS, this is the first step towards a comprehensive and fast ammonia release response system, capable of predicting the behaviour of an ammonia plume and directing emergency mitigation services accordingly.
To note, ammonia is viewed as a promising fuel solution for a more sustainable industry but its high toxicity presents operational challenges on board and ashore.
Christopher J. Wiernicki, ABS Chairman, President and CEO, said: “Our advanced simulation and modelling approach is already shining a light on the unique behaviours of this fuel in a range of scenarios. This will inform the strategies of ports, crews and emergency services and enable immediate and informed response to an ammonia release.”
