“…To investigate human behaviors in evacuations on inclined ships, researchers from many institutions, including the Korea Research Institute of Ships and Ocean Engineering (KRISO), 26 Netherlands Organization for Applied Scientific Research (TNO), 27 Swiss Federal Institute of Technology in Zurich (ETH), 28 BMT Fleet Technology (BMT), 29 Research Institute of Marine Engineering of Japan (RIME), and Maritime Research Institute of Japan (NMRI), 30,31 Hamburgische Schffbau-Versuchsanstalt (HSVA) 10 and Dalian Maritime University (DMU) 32 have conducted studies based on real data or simulators. Sun et al 33 conducted a series of experiments in which 17 students walked on an inclined corridor simulator with a length of 10.0 m, width of 1.8 m, and height of 2.2 m. The results showed that trim angles have a greater influence on the free and fast walking speed than heeling angles.…”

“…36 BMT Fleet Technology conducted relevant experiments on a motion simulator SHEBA, which consists of a corridor model with stairs and a room, and the simulator can be inclined around one axis up to 22°. 29 Katasuhara et al 30,31 from the RIME and NMRI not only reported that the average walking speed of students who participated in their experiment was 1.4 m/s but also designed a device that can change the width of the corridor for inclination tests to study how pedestrians’ speeds influenced by trim and heeling angles. Considering the factors of safety and experimental costs, simulations of ship evacuation have gained popularity, and inclination angles were extended in these simulations.…”

The emergency scenarios of passenger ships are reproduced unrealistically by evacuation drills due to cost and safety limitations, and model simulation is an effective alternative method. To study the evacuation efficiency of an inclined ship, a deck of a Ro-Ro ship with 1065 passengers was modeled on a simulation platform developed based on a social force model (SFM). A series of inclined scenarios were produced by adding the walking speed attenuation factor to the individual parameters. Furthermore, the influence of crew’s guidance was considered in this model, and the effects on evacuation were also analyzed for the entire deck. The simulation results show that the larger the inclination angle is, the more evacuation time that is needed. When the largest inclination angle was 20°, the evacuation time increased by 32.6%. In addition, the participation of crew’s guidance in all of these scenarios significantly accelerated the evacuation efficiency, and this benefit was achieved by the evaluation of the exit flow and congestion level by crew. However, organizing orderly evacuations as soon as possible when the inclination angle is less than 15° and making maximum efforts to ensure evacuation success are still recommended. The findings provide useful insights into a large group of Ro-Ro passenger vessels under inclined emergency evacuation.
