REI® Model Testing
The Rapid Empirical Innovation (REI®) design & development services program by MSHIPCO literally takes testing “out of the box” of traditional tow tanks to quickly and accurately evaluate valuable design concepts that otherwise would lie dormant and unexplored. The REI® services process is a means for developing and refining innovative marine concepts in time- and cost-effective manners.
Hull models are evaluated on a self-powered, open-water tow testing platform that provides real-time force, trim and acceleration measurements to optimize performance and ride quality.
The platform is fully rough-water capable. High-frequency 6-DOF accelerometers are outfitted to each model yielding comprehensive motion and acceleration comparisons in identical as-tested wave conditions.
Three (3) models, including the historically tested Series 62 model, were tested at DTMB for both smooth and rough water testing so comparison could be made between the towing tank data (DTMB) and the REI® services system.
The results were excellent for both calm and rough water, even exceeding our 95% threshold. The REI® services calm water resistance measurements have been shown to have an absolute accuracy to +/- 3% at 15 knots model scale. Notably, when resistance differentials are normalized to a baseline test configuration, the resistance and performance trending across a spectrum of model fabrication is improved further.
