Jinye provided hub vortex fins, anti-vortex fins, and propeller boss cap trimming services for an 18,000 DWT bulk carrier to improve hydrodynamic performance, reduce fuel consumption, and enhance sailing efficiency. PSV consists of a duct and several pre-swirl vanes positioned ahead of propeller. The vanes sign as FIN 1~5. PSV can correct the flow into the propeller which essentially reduce the rotational losses in the propeller slipstream and increase the flow velocity towards the inner radius of the propeller.The expected reduction of PSV is the range of 3% to 8%.

For a 230,000 DWT bulk carrier, Jinye implemented hub vortex fins, anti-vortex fins, and propeller boss cap trimming modifications to improve vortex-induced resistance, improve propulsion efficiency, and achieve significant energy savings. HVAF is attached with small fins on the boss cap. The number of fins is same as that of the propeller blades. HVAF mainly recovers the energy loss of propeller hub vortex in propeller down stream. The geometry shape of HVAF is very simple, and HVAF can be installed behind the propeller easily as original boss cap, which rotates together with the propeller. HVAF can save fuel consumption by 2%~5% as operating at the same speed.

In the shipbuilding and marine engineering industry, every detail optimized can lead to a leap in overall performance. As an advanced manufacturer of high-performance propellers, we have collaborated closely with MSC to implement innovative scraping and fitting technology, significantly increasing the contact area between the propeller taper bore and the shaft system. This breakthrough sets a new benchmark for vessel stability and transmission efficiency. To meet MSC’s requirements, we applied advanced scraping and fitting techniques, utilizing high-precision machining and localized grinding. This optimization delivers multiple advantages: More uniform stress distribution: Reduces localized wear, extending the service life of the propeller and shaft system. Higher transmission efficiency: Tight contact reduces power loss and improves fuel economy. Enhanced operational stability: Effectively prevents vibration and loosening, ensuring safer navigation.
