ROI Calculation Logic

This technology could reduce model ship test preparation by ~80%. For a facility conducting 200 test days/year, with 2 operators spending 2 hours/day on draft adjustment, this could save 800 hours annually. At an hourly rate of ~$35/hour (AI est.), this translates to direct labor cost savings of ~$25K/person/year (AI est.), totaling ~$50K/year (AI est.) for two operators. Additionally, accelerated test cycles could reduce opportunity costs by ~$65K/year (AI est.) from shortened development periods, leading to a total estimated economic impact of ~$100K/year (AI est.).

Speed to Market
4× faster than in-house development
Developed by a national research institute, this technology's automated draft adjustment algorithms and control systems are already established and proven. Licensees can bypass ground-up R&D, focusing instead on integration and calibration with existing model ship testing facilities. This approach could significantly accelerate development timelines, potentially reducing time-to-market by approximately 2.7 years.
