A CFD study on the assessment of a naval ship manoeuvrability in steering and engine failure situations
A CFD study on the assessment of a naval ship manoeuvrability in steering and engine failure situations
A critical concern for naval vessels is survivability during manoeuvring operations. When failures occur in steering and propulsion systems, the ship's overall survivability can be severely compromised. Twin rudders and propellers are commonly employed in naval ship design, offering redundancy when systems on one side fail, thereby enabling twin-screw vessels to continue operating using the functioning systems on the opposite side. This study evaluates the manoeuvring performance of twin-screw warships during system failures. The research examines three failure scenarios: engine failure, steering failure, and combined failures (simultaneous engine and steering failures). These effects are assessed using a free-running manoeuvre model of the Office of Naval Research Tumblehome (ONRT) hull through Computational Fluid Dynamics (CFD) simulations. The findings from this study provide insights into twin-screw vessel manoeuvrability under critical system failure conditions.

Abstract
A critical concern for naval vessels is survivability during manoeuvring operations. When failures occur in steering and propulsion systems, the ship's overall survivability can be severely compromised. Twin rudders and propellers are commonly employed in naval ship design, offering redundancy when systems on one side fail, thereby enabling twin-screw vessels to continue operating using the functioning systems on the opposite side. This study evaluates the manoeuvring performance of twin-screw warships during system failures. The research examines three failure scenarios: engine failure, steering failure, and combined failures (simultaneous engine and steering failures). These effects are assessed using a free-running manoeuvre model of the Office of Naval Research Tumblehome (ONRT) hull through Computational Fluid Dynamics (CFD) simulations. The findings from this study provide insights into twin-screw vessel manoeuvrability under critical system failure conditions.
