GNV has partnered with RINA to utilize its SERTICA Performance system for optimizing energy usage on its new vessel, GNV Polaris. The testing commenced during the ship’s inaugural journey from China to Italy. SERTICA Performance is designed to monitor operational data, enabling GNV to manage energy consumption efficiently and enhance overall performance. The system has successfully identified two optimal operating scenarios that lead to the lowest Specific Fuel Consumption (SFC) and developed a predictive model that serves as both a benchmark and a simulator for future operations.
This advanced monitoring system acts as a real-time data collector, leveraging sensors installed on the vessel to track essential metrics, including fuel consumption and the power output of diesel generators and engines. While its primary focus is on energy expenditure, the gathered data also facilitates the evaluation of the ship’s actual efficiency, offering a comprehensive view of its operational performance for both the onboard crew and onshore management. During the voyage, various operational scenarios were tested, including adjustments in speed and configurations, such as alternating diesel and shaft generators. These simulations aimed to discover the most fuel-efficient solutions, particularly for the Genoa-Palermo route.
The results demonstrated consistency with forecasts and validated the system’s precision in defining optimal configurations for fuel reduction. In addition to real-time monitoring, the project involves developing predictive models through machine learning techniques. A physical model of the ship, informed by the collected data, showed remarkable accuracy in estimating efficiency over time. These performance models serve crucial roles in assessing degradation and simulating various operational scenarios, enabling the identification of necessary maintenance actions.
GNV’s progress in sustainable shipping is highlighted by Ivana Melillo, the Energy Efficiency Director, emphasizing the introduction of the GNV Polaris, the first of four new eco-friendly ships. This vessel is expected to achieve over 30% fuel savings and significantly lower CO₂ emissions compared to existing ships in the fleet. GNV intends to expand its modern fleet with higher environmental standards and explore alternative fuels such as liquefied natural gas and biofuels, further contributing to sustainability in maritime transport. Lars Riisberg, Marine Digital Solutions Executive Director at RINA, praised SERTICA Performance for its data monitoring capabilities.
The system collects data every five minutes and transmits it for detailed analysis and fuel budget planning. Its real-time dashboards enable continuous monitoring, while alerts for sensor status support prompt detection of anomalies. SERTICA Performance also tracks hull deterioration and energy efficiency, allowing for informed decision-making against optimal conditions. Currently implemented on over 800 ships, SERTICA Performance is set to expand with additional installations on new vessels under construction.
