The Numerical Tow Tank: How CFD Can Help You Meet EEDI Requirements without Compromising Vessel Speeds
Thursday, November 13, 2014

In January 2013, the IMO (International Maritime Organization) introduced the EEDI (Energy Efficiency Design Index) as a way to evaluate the energy efficiency of new vessels. The purpose of the EEDI regulation is to reduce the CO2 emissions from ships. This often leads designers and operators to reduce engine sizes and consequently emissions and operation speeds.

This educational webcast demonstrates CFD (Computational Fluid Dynamics) is being used to evaluate and improve designs to reduce drag from the hull and appendages and maximize thrust from the propulsion system in order to reduce the vessel’s energy requirements.

In addition to accurately predicting the performance of design variants, CFD can be successfully used to predict performance in different waves and sea-states: real operating conditions.

Presenters provide an introduction on how naval architects are using engineering simulation software within the ship design process and on a new workflow automation tool EHP (Estimating Hull Performance). These tools reduce the learning curve and model set-up time, as well as embed best practices.
