Project Period:

2009 - 2010

Issues concerning emission reduction of particular relevance in the design stage may be summarised in four key factors, none of which may be neglected during the different design stages, but where DEO will focus on items 1 and 2: 1.Increasing the logistic s chain efficiency (kWh /work) 2.Increasing the efficiency of the ship(s) (kWh /work) 3.Increasing the specific fuel efficiency (g fuel/kWh) 4.Reducing the specific emission per fuel unit (g emission/g fuel) Uncertainty and lack of knowledge within the a rea makes the task difficult for a ship designer or a ship owner who wishes to design the optimum solution for a particular maritime logistics chain. Thus, there is an urgent need to develop methodology and tools supporting this early stage design process . The project has therefore defined the following sub-goals, taking into consideration the fact that the span in level of detail, and also knowledge needed, is very large: -Prediction of actual fuel consumption and emissions from overall ship characteris tics (speed, deadweight/displacement, power and/or main dimensions) in combination with a realistic vessel operation profile. -Estimation of energy and environment efficiency of a particular ship in terms of a modeling and prediction of its real behavior or formal standard indices (such as those mandated by IMO). -Modelling important decisions made during logistics chain, fleet optimization analysis, or ship basic design, so as to view their effect on important indicators (as in 2). -Integration of ship design tasks into value chain scenarios in order to at design time compare total work performed by a fleet setup/logistics chain (e.g. ton-mile transported per year) to total emission to air, fuel consumed or energy costs incurred. -Enabling where applica ble the evaluation of environmental efficiency of ships not covered by IMO, such as offshore vessels/work boats. The project will include use cases covering 1 offshore and 1-2 merchant supply ch cases
