Results: Interstream Barging’s two new tankers Spinoza and Huygens recently entered service. Both vessels have a length of 110 meters and 11.45 meters beam. The hulls came from Gebr. of Jonge Shipbuilding Service and both completed their outfitting at Asto Shipyard in Raamsdonksveer, the Netherlands. The design of these chemical tankers focused on a combination of load capacity, efficiency and comfort. In cooperation with our partner Berger Maritiem, VICUSdt took care of designing and delivering the propeller and nozzle for both ships.
This case study showcases how VICUSdt boosted inland waterway chemical tankers efficiency for two new Dutch vessels—Spinoza and Huygens. By applying CFD resistance predictions and hydrodynamic hull analysis, VICUSdt delivered bespoke propeller and nozzle designs that significantly improved propulsion performance.
Both vessels met expected speeds during sea trials, operating with exceptionally low noise and vibration levels in accommodation and wheelhouse. This led to optimized operational efficiency and enhanced crew comfort—demonstrating the power of CFD-informed vessel design.
Key Hydrodynamic Enhancements & Performance Outcomes
VICUSdt’s contribution included CFD-based hull resistance modeling, simulation of wave patterns, and precise propeller–hull interaction analysis through self-propulsion testing. From the CAD-generated hull geometry, CFD resistance calculations at multiple speeds allowed for accurate power and speed forecasts—not statistical estimates—coupled with cavitation assessment to reduce noise, vibration, and erosion risk.
This level of insight ensured that propellers designed for ICE Class requirements had thicker blades for robustness, while nozzles were tuned to match the operational profile of inland waterways. The resulting design delivered smoother, quieter, and efficient navigation for both tankers—which is key in environments where vibration and acoustic performance are critical.
Results & Operational Impact for Shipowners
Spinoza and Huygens achieved all design targets during trials—attaining expected speeds while ensuring high onboard comfort. Both operating smoothly with minimal noise and vibration, these tankers offer significant operational advantages: enhanced fuel efficiency, superior crew comfort, and robust performance.
Interstream Barging expressed full satisfaction with the results, noting the vessels as “very quiet chemical tankers that navigate smoothly with good propulsive performance.” This case highlights how inland waterway chemical tankers efficiency can be practically elevated through CFD-based engineering—benefiting shipowners with measurable performance gains and operational excellence.
