Suitability of Royal Australian Navy Standard Work Week in Relation to Fatigue Levels for Operational Taskings

Abstract

This thesis assessed the manning structure of HMAS Warramunga in at-sea conditions against Navy Standard Work Week (NSWW) criteria such that a Scheme of Complement (SoC) is sufficient to meet the workload and sustainment requirements. IMPRINT Pro Forces Module was used to model planned activities and unplanned events of sailors to include the Marine Engineering Department to assess workload, daily sleep duration (DSD),training, service diversion activities, and task completion rates. Results showed that the crew slept less and worked more than the NSWW criteria. Also, completion rates for all but the highest priority events were low. These findings indicate crew had little surge capacity available without sacrificing administrative and maintenance tasks. With clearer understanding of the limitations on the ship imposed by crew size, decision-makers will be able to assign operational tasking based on knowledge of expected endurance of a ship to maintain such an operational tempo. Findings indicate that the NSWW in its current state should not be used solely to define ships SoC. However, using modeling and simulation (M and S) combined with SMEs knowledge will provide insight on crew workload, lead to improved SoC, and fulfill the ships Statement of Operating Intent (SOI). Another potential application of IMPRINT could be to assess the ships pre-sailing risk state based off the ships current manning levels and maintenance requirements.
