On the basis of a scientific study (eg literature, analyzing current fleet, studying available data from previous fade tests (sea) ships, ...) identify measures to reduce energy consumption and / or to reduce emissions in the transport can lead by considering in detail how the design of a barge can be optimized in order to: - reduce the sailing resistance (design hull); - to increase the efficiency of the propulsion propeller (increase hydrodynamic efficiency screw by improving the design and making the right choice of screw) - to optimize the efficiency of the engine (increased engine thermal efficiency by improving the design and making the correct choice of engines), and; - in yet another way to reduce fuel consumption and emissions. a measure described perform a cost-benefit analysis by quantifying the one hand the financial and environmental benefits can be realized with it (% less fuel consumption and related costs for the owner / operator% less CO2 and other greenhouse gases and% fewer emissions of other pollutants such small particles, sulfur and NOx) and secondly to estimate what each expected additional costs for the owner / operator of the barge (more costs in the purchase and / or use, any loss of load efficiency, ...).
