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

Treating the ship as an autonomous floating vehicle, onboard energy systems have to be designed to ensure high reliability for the safety of the ship per se and, also, of the passengers and crew under all operating conditions and emergencies at minimum cost. To date, these objectives have been achieved by strict safety regulations, design simplicity and component redundancies in safety-critical systems at the design stage. However, designing the systems with the current measures, the cost-ineffectiveness of the former approach would suffer. In addition, lack of strict regulations concerning environmental impact and also the relatively low vessel operation costs, lead to energy savings not being considered as driving force in the shipping industry. The recently introduced IMO regulations came into force to address the above objectives, imposing specific requirements during ship design and operation. This paper introduces a novel methodology for improving onboard systems availability and energy efficiency by logical and numerical modelling of the shipboard electrical energy systems during design and operation through the combined assessment of electrical power systems availability and quantitative performance. These, i.e. availability and performance, linked to initial and operating costs allow for multi-objective design optimisation of the electrical power systems.
