Abstract:
Rapid stopping capability is a critical safety feature for ferries operating in confined waterways. Otherwise known as the crash stop, this maneuvre is a well-studied characteristic of maneuvrability for large oceangoing vessels, in particular with regard to the ability of a large tanker to stop in the event of an impending collision or allision. However, crash stop performance is difficult to characterize for smaller, higher-powered vessels such as ferries with propulsion machinery that allows rapid reversal of shaftlines.
In addition, the influence of propeller geometry on crash stop performance is poorly quantified. This presentation proposes a simulation method using four-quadrant data to evaluate crash stop performance. Two notional case study vessels are introduced and used to develop insights into the influence of propeller design parameters on crash stop performance. This approach demonstrates how large-scale simulation can convert scattered design intuition into quantitative guidance for safer and more efficient operations.
This presentation is based on a paper Alex and Ben prepared for SMC 2025 called “Time Step Analysis of the Crash Stop Maneuver for Ferries.
