Power * fuel consumption * CO2 emission factor Capacity * ship speed

Political, economic and ecological settings / TARGETS

Constraints and Issues (to be considered):

• Fuel price

• EEDI / (EEOI)

• Emissions

• Emission Control Areas

… Call for a careful and responsible use of resources (energy => emissions)


Setting the TARGETS

Objectives • Develop a holistic simulation and optimisation concept to

improve energy efficiency of transport shipping. • Based on a Dynamic Energy Model the most relevant energy

consumers on board and the use of new, alternative energy sources shall be analysed and subsequently improved.

• Simulating and optimising energy consumption at – the design stage and – during operation

• Providing Guidelines for future energy efficient cargo vessels.

Operation & Scenarios Energy Audits for validation and benchmarking of DEM


TARGETS performed a number of energy audits on board cargo ships: • container vessels, • bulk carriers , • tankers , • 1 RoRo vessel

Determination of optimal operational conditions • Case studies for several vessels incl. different speed and

operational profiles. • Life-cycle analysis

Compilation of a consolidated list of Energy Saving Potentials (ESPs) • Based on findings from energy audits, • Covering M/E performance as well as operational patterns. • Optimisation in the context of DEM.

Integration and simulation TARGETS Workshop, London 13 March 2014 14

• DEM integrates knowledge from component-level to ship-system level.

• Interactions between energy systems fully respected. • Example DEMs for Bulk Carrier and Container vessel have

been developed. • The performance of ship energy systems is assessed by

time-domain simulations. • To be shown in a life demonstration later.
