WebThe study presented here shows how shipowners can benefit from a preliminary Computational Fluid Dynamics (CFD) analysis before deciding to install a particular Energy Saving Device (ESD) to improve the Energy Efficiency Existing Ship Index (EEXI). CFD simulations offer a cost-effective way to reduce the risk when deciding on which ESD to … WebA diesel-electric propulsion system similar to SAVe Line, where generating capacity can be reduced by up to 30% by introducing energy storage. The vessel can operate on batteries alone when in harbour or for limited periods with zero emissions, dependent on the specified battery capacity.

WebAug 28, 2013 · The development of energy-saving devices is also underway in order to increase the ship’s propulsion efficiency. For example, specially designed fins on ship’s hull or propeller blades, waste ... WebSep 29, 2024 · The present paper numerically investigated the effect of different energy-saving devices (ESDs), which are mounted at the upstream zone on the ship propeller performance enhancement. Four types of ESDs are selected: the pre-swirl stator (PSS), wake equalizing duct (WED) and pre-swirl ducts, namely PSD-1 and PSD-2. The full … WebThe solution consists of multiple curved fins and a ring attached to the ship’s hull to prevent the power losses that typically occur in a propeller’s slipstream. Key benefits Improve fuel efficiency by up to 10% in combination with a new propeller design and Wärtsilä EnergoProFin Reduce NOx and CO2 emissions nw windows installation in yelm
