The Use of the Crew Size Evaluation Method to Examine the Effect of Operational Factors on Crew Needs
Abstract
The Crew Size Evaluation Method (CSEM) is a task-based approach to determining crew size on commercial ships. CSEM was used to examine the effects of three factors on crew needs: port call frequency, shoreside maintenance support, and three different sets of work/rest standards (U.S. Oil Pollution Act of 1990 (OPA 90); Seafarers' Training, Certification, and Watchkeeping Code (STCW); and International Labor Organization Convention 180 (ILO 180)). The analyses identified how these changes resulted in differing needs for particular crew types and shipboard tasks. This demonstrates CSEM's ability to clarify how different operational scenarios impact crew needs and to aid in determining how to redistribute tasks to other crew members or add additional crew in order to avoid overloading particular crew members. This is one of two reports on the use of CSEM to evaluate crew needs under different operational scenarios. This report contains a detailed description of how CSEM is used to analyze scenarios and discusses several criteria, which can be applied in the evaluation of sufficient crew. A related paper, "Simplified Crew Size Evaluation Method," CG-D-13-00, explains how the full-scale analyses from CSEM can be packaged into simple lookup tables, yielding a quick and practical tool for crew size evaluation.
