European researchers focus on ship energy efficiency
Energy efficiency and environmental considerations are today’s driving force for ship operators to reduce costs and become greener. Dr Jochen Marzi, director CFD and Research at HSVA explains the latest programmes
of the associated emissions. While these constraints became apparent some years ago, major European maritime stake holders started a number of research activities to aid the industry to meet expected environmental targets as well as cut costs related to energy consumption for seaborne transportation. At present, the Sustainable Surface
E
Transport Programme within the EU’s 7th
Framework Research Programme
contains no less than eight R&D projects directly addressing energy efficiency and environmental aspects. Tese projects form the core of an initiative gathered under the name of Green Ship Energy Efficiency Network – GreenSEENet – which is further complemented with other research performed for example on national levels at the various member states. Tis network of energy efficiency and
greening activities is expected to deliver the technologies of the future which will help to render shipping greener and more cost efficient in the future. Te following article describing the TARGETS project is meant to start a series of similar stories on a number of related on-going developments.
TARGETS for seaborne transportation The EU funded TARGETS project – Targeted Advanced Research for Global Efficiency of Transportation Shipping (
www.targets-project.eu) – provides substantial improvements to ship energy efficiency by adopting a holistic approach to model and optimise energy consumption with a focus on a variety of operational conditions encountered through the life-cycle of a vessel. Lead by coordinating partner HSVA, 11 partners form industry and research / academia have joined forces

conomic pressure and international legislation require a sensitive use of energy resources and a reduction
in this project. Tese include: University of Newcastle, University of Strathclyde/SSRC, Maersk, Alpha Marine Systems, CMT, Istanbul Technical University, Technical University of Hamburg-Harburg, Marterra S.A., Safety at Sea and the Shipbuilders and Ship repairers Association UK. Developments comprise tools and
concepts to be applied in ship design and operation. Integrating component-based knowledge of resistance and propulsion, main on-board energy consumers and alternative/renewable energy sources at system-based level, the TARGETS energy model will allow the group to achieve significant improvements to the overall energy efficiency of ships through using advanced modelling techniques.
The TARGETS concept Ship emissions are directly related to
the energy efficiency of
with a ship not optimised for energy consumption. The most efficient solution will consequently be to first save energy and, in a second stage apply additional technologies to artificially reduce emissions, which in turn will consume mostly additional energy. The TARGETS project focuses on a holistic analysis and improvement of energy aspects related to ship operation at sea. To achieve the goal of a ship optimised
for energy consumption the TARGETS project takes a holistic view at the causes of the use of energy during ship operation. In doing so, the project addresses:
• The most important hydrodynamic
causes for energy consumption, for example ship resistance and propulsion.
• Promising technologies for auxiliary energy generation (from non-
fossil sources) ship
operations. Besides technical features such as exhaust gas cleaning or similar, an energy efficient vessel will always prove to be a “cleaner” vessel compared
• Te management of energy consumption onboard a ship
• Te integration of technologies to reduce energy consumption into a holistic
management & simulation system. Figure 1. The TARGETS Concept – a holistic energy model for transport vessels
