Project C5 - Targets - Targeted Advanced Research for Global Efficiency of Transportation Shipping

Principal Investigator: Thomas Rung

Scientific Background and Motivation

The prime goal of TARGETS - Targeted Advanced Research for Global Efficiency of Transportation Shipping – is a global analysis of the most important causes of  energy consumption on board of cargo ships in a comprehensive and holistic approach. Having identified resistance and propulsion aspects as primary causes of energy consumption, work will be dedicated to the improvement of such characteristics. In addition, a global energy consumption simulation system will be developed to be applied during new vessel design as well as during operation. Assembling leading fluid dynamics and energy specialists the project will contribute designs, tools and operational guidelines for an energy efficient operation of cargo ships, and hence make a significant contribution to the reduction of green house gas emissions.

Aims and Objectives

A focal point of the project is the improvement and application of a resistance-based aft-body shape optimisation tool using a continuous adjoint approach to full-scale configurations. The method provides the gradient distribution over a complete surface at the cost of one primal solution and is perhaps the most efficent approach to shape optimisation. Moreover the continuous sensitivity distribution provides a particularly rich insight into the design opportunities. All efforts will be performed in the framework of the inhouse adFreSCo+ solver.
