Many different energy-saving devices have been studied to either correct the performance of a suboptimal ship design or to improve on already optimal or near-optimal designs. A range of these devices are aimed at improving propulsion (e.g. wake-equalizing ducts, rudder bulb fins, etc.), reducing skin friction and utilization of renewable energy sources. Through the use of CFD to evaluate various compatible combinations, these devices can be explored to provide guidance to a vessel owners on enhancing energy efficiency.
In addition, we provide a CFD-based integrated hull, propeller, rudder and energy-saving device analysis of a complete vessel. This is a cost-effective approach to assess the ship’s performance under various operating conditions, providing an opportunity to evaluate various design concepts.
