A Holistic Approach for Energy Flow Simulations in Early Design

AbstractThe project focusses on the integration of energy saving technologies in the early design stage of ships, using advanced simulation models to be developed for the energy grid of the ship. The optimum combination of energy consumers incl. energy recovery systems is expected to significantly improve the vessels overall energy efficiency. The challenge will be to harmonize the modelling approach from technology providers in a way that component models can be used appropriately for energy modelling on ship level.The results of the simulation of the ship concepts as developed in the 11 application cases will be used for a screening life cycle assessment, using the “well to propeller” concept to properly address the use of alternative fuels. A LCPA (Life Cycle Performance Assessment)-Tool allows for the comparison of different technical solutions taking into account environmental and economic parameters. A suitable way of representing the external costs of air emissions will be integrated in order to be able to fully compare new technical solutions with existing state of the art technologies in ship designs for provision of political recommendations
