Abstract
As part of a project for the National Research Council, a functional analysis model previously was developed and initially validated on two large maritime vessels for determining minimum safe crew size. The present study collected operations and maintenance data for all functions performed in port, in restricted waters, and at sea for three voyage profiles for two identical tankers. Structured interviews with crew members were used to collect the data. One ship was crewed by an all Korean crew; the other by Italian officers and Philippine seamen. Results from the two independent applications of the model were highly consistent for both qualitative and quantitative crew requirements. These results provided further validation both for the model and the method of data collection. The model then was used to project changes in crew requirements for different voyage profiles, thus demonstrating its utility as a management tool. Cultural differences in operations management were noted.
