Following the launch of its Resid Upgrade Plant in 2014, Tüpraş İzmit faced rising crude oil type diversity, product complexity and pressure from port-based sales that increased jetty congestion. In response, the refinery launched a digital transformation, integrating planning, inventory and logistics across the value chain. By deploying AI-driven forecasting and optimization solutions, the site improved delivery reliability from 85% to 95%, shortened average truck loading times by 75%, increased forecasting labour productivity by 48%, reduced CO₂ emissions by 8% and water consumption by 31%.
