Abstract
The walking speed of passengers is important in estimating the time re-quired to evacuate a ship. Therefore we investigated the walking speed on stairs and in corridors during ship listing and dynamic ship motion condi-tions, using the TNO Ship Motion Simulator. Data were obtained from sub-jects between 18 and 83 years of age. Ship listing reduced walking speed up to about 35, dependent on the direction of tilt. Seniors were about 15 slower than other age categories. Ascending stairs slowed down walking speed up to 40 for all age categories, descending up to 30. Another find-ing was that people needed the handrail during ship listing. This imposes a considerable reduction on the specific flow through the escape ways. Dy-namic ship movements slowed down walking speed up to 15 with in-creasing frequency and with increasing amplitude. At large eccentric posi-tions, parasitic linear accelerations will be the main factor reducing specific flow: passengers need handrails if these accelerations exceed 0.5 m/s². For the purpose of predicting the time required for evacuations, the reduction in passenger walking speed and the reduced capacity of escape ways should be taken into account in the IMO guidelines.
