The Submarine Habitability Assessment Questionnaire: A Survey of RAN Submariners

Abstract

This paper reports on the development, method, and major findings from the Submarine Habitability Assessment Questionnaire (SUB-HAQ) undertaken as part of a lessons-learned review of the current RAN submarine platform. The questionnaire was completed by 167 Royal Australian Navy (RAN) Submariners and was developed to examine the perceived habitability of the main living and working areas. The results showed satisfaction with cleanliness, lighting, privacy of amenities, ventilation in certain areas, and location of amenities and facilities. The results also suggest dissatisfaction with aspects of the work areas (such as storage space for work materials, and space to conduct off-watch work), allocation of space and equipment for exercise, crowding, and ratio of crew to amenities. Best use of space on a submarine is an extraordinarily challenging design problem. However, it was concluded that significant benefit could be achieved through applying human systems integration methods early in the design of a future RAN platform. The importance of careful workforce planning and crewing analyses to prevent occurrences of overcrowding, lack of storage, and an unacceptable ratio of crew to amenities was observed. The findings from SUB-HAQ have led to a significant investment in evidence-based habitability design assurance by the RAN.
