Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Application of pod propulsion on a variety of vessels such as cruise ships, ropax, and tanker vessels has increased significantly over the last two decades owing to the benefits offered by pods. Despite the clear benefits, operators are still reluctant to have this innovation on board because of unknown overall reliability. Many of the published research efforts in the area of pod propulsion have been concentrated on hydrodynamics and manoeuvring aspects with little in the area of quantitative pod reliability assessment. In this paper, the applicability and appropriateness of various quantitative fault tree solution techniques (exact and approximate) for the reliability assessment of a generic pod propulsion system are investigated. Also, the paper demonstrates that the proposed quantitative reliability assessment methodology can be used to make design changes by identifying critical components in system functionality and modifying the system with improvements, where needed.
