Компании Furuno и Shin Kurushima подтвердили точность масштабных CFD-симуляций для танкеров

KEY POINTS Furuno Electric and Shin Kurushima Sanoyas Shipbuilding validate full-scale tanker CFD simulations for port and starboard turns Turning-circle errors stay below 1% for starboard turns and below 5% for port turns Research supports maneuvering-performance forecasts based on operating data, targeting safer operations and improved energy efficiency Furuno Electric Co. and Shin Kurushima Sanoyas Shipbuilding have validated computational fluid dynamics, or CFD, simulations of a tanker's full-scale turning maneuvers by comparing the results with measurements from an operating vessel, Furuno said on September 8. The companies analyzed port and starboard turns of Shin Kurushima Sanoyas Shipbuilding's Sanoyas Tanker design directly at actual vessel scale. The project is intended to improve the accuracy of maneuvering-performance forecasts based on operational data and strengthen technologies supporting safer vessel operations, Furuno said. The simulations produced advance-distance and turning-circle results that closely matched the shipboard measurements. Errors in the turning circle were below 1% for starboard turns and below 5% for port turns, according to the release. The study accounted for surface roughness equivalent to that of the vessel hull and rudder in service. Furuno said the results show that direct full-scale CFD analysis can reproduce the ship's turning characteristics with practical accuracy. The analysis used FINE/MARINE 2025.1 software and incorporated six-degree-of-freedom vessel motion, the free water surface and propeller thrust. The companies also examined factors behind differences between simulated and measured values, as well as potential simplification of the analysis model, to identify areas for further accuracy improvements. Turning trials traditionally require sea trials or model-basin testing, both of which can involve extensive equipment and personnel and can be affected by weather and sea conditions. CFD modeling is being used to numerically reproduce fluid behavior and vessel movement as an alternative method for assessing maneuvering performance. Furuno presented the research at the Japan Society of Naval Architects and Ocean Engineers' Autumn Conference 2025 and at the Symposium on Naval Hydrodynamics 2026. The company said it plans to continue improving forecasting accuracy for applications in vessel safety and energy conservation.
