Targets Project Background

Background

Energy efficiency and environmental considerations both are among today’s driving forces determining maritime operation. Economical pressure and international legislation require a sensitive use of energy resources and a reduction as well as a proper treatment of associated emissions. To address ship energy efficiency in a holistic way, HSVA, together with a group of twelve leading EU maritime research organisations and shipping operators, has initiated a new EU project:

The TARGETS – Targeted Advanced Research for Global Efficiency of Transportation Shipping – project was submitted to the 3rd Call of the Surface Transport Programme and will launch shortly after negotiations have been finalised. TARGETS aims to provide substantial improvements to ship energy efficiency by adopting a holistic approach to energy generation, transmission, consumption and operational management with focus on life-cycle issues. Use is made of all contemporary developments at scientific and practical levels to enable technologies, tools and strategies that could facilitate step changes in energy generation / utilisation onboard ships. For maximum benefit concerning impact on energy efficiency and the environment (energy efficiency and environmental sustainability are inextricably linked) ocean-going cargo ships are singled out, such ships undoubtedly being the largest consumers of energy as these ships constitute the backbone of maritime transport (hence the effect from any improvements of energy efficiency will be large scale).

Hydrodynamic aspects play an important role in energy consumption of cargo vessels. The following figure indicates that almost 80% of all practically available energy generated aboard an ocean going cargo ship is applied to overcoming hydrodynamic forces (and losses). This offers a vast potential for improvements, especially of ship resistance and propulsive efficiency.

Adopting a systematic methodology that integrates component-based knowledge of resistance and propulsion at system-based level (shipboard systems / plant configuration) and the development of a suitable simulation tool for the prediction, evaluation and management of energy performance in ship design and operation for varying operational profiles is a key aim of TARGETS. Whilst emphasis will be placed on improving understanding of the hydrodynamic aspects of energy consumption, advanced or unconventional energy generation and management concepts will also be considered. Comprehensive analyses of different operational profiles will reveal key design and operational parameters for optimum energy consumption during a ship’s life cycle.

Assembling leading European fluid dynamics and energy specialists and major EU shipping operators covering a broad range of cargo transport operations (containers, bulkers and tankers), the TARGETS project will deliver a systematic methodology for a holistic energy performance evaluation and prediction and a robust simulation tool, capable of facilitating life-cycle optimum energy consumption, coupled with all requisite design information at ship and systems levels, tools and operational guidelines; hence make a significant contribution to the cost effectiveness of shipboard transportation but much more significantly to the reduction of greenhouse gas emissions.
