Strathprints makes available scholarly Open Access content by researchers in the Department of Architecture based within the Faculty of Engineering.

Research activity at Architecture explores a wide variety of significant research areas within architecture and the built environment. Among these is the better exploitation of innovative construction technologies and ICT to optimise 'total building performance', as well as reduce waste and environmental impact. Sustainable architectural and urban design is an important component of this. To this end, the Cluster for Research in Design and Sustainability (CRiDS) focuses its research energies towards developing resilient responses to the social, environmental and economic challenges associated with urbanism and cities, in both the developed and developing world.

Abstract

In this paper, a new ship weather routing system is developed towards enhancing energy efficiency. The routes searching is essentially regarded as an optimisation process with two objectives, which are respectively ETA (estimated arrival time) and fuel consumption. When ship characteristics, loading conditions, ship speed, and sea conditions (wave, wind and currents) are imported to this system, together with departure and final points and departure time, a set of minimum fuel consumption routes under different ETA can be achieved. In this way, an optimal and safe enough route can be decided according to shipping schedule. A combination of global and local optimisation strategy is used in weather routing optimisation. Finally, an Aframax Oil Tanker is taken as a case study to prove the validity of this ship weather routing decision system.
