Propeller Boss Cap Fins for Fixed Pitch Propellers
Custom Ni-Al Bronze (Cu3) propeller boss cap fins for fixed pitch propellers, designed to weaken the hub vortex and smooth flow behind the propeller; made to propeller drawings for cargo ships, tankers, container ships and retrofits.
Description
JinYe Propeller's Propeller Boss Cap Fins (PBCF), also called Hub Vortex Absorbed Fins, are energy-saving appendages for fixed pitch propellers. Fitted behind the propeller hub, the fins weaken the concentrated hub vortex and guide water flow more smoothly, reducing energy loss and supporting propulsion efficiency without increasing engine output.
Key features
- Hub vortex reduction and flow guidance behind the propeller
- Custom fin arrangement matched to blade number, rotation direction and hub geometry
- Drawing-based manufacturing for fit with the existing propeller and shaft arrangement
- Compact retrofit option for propeller replacement, maintenance or dry-dock projects
- Fuel savings depend on vessel-specific analysis; can form part of an EEXI/CII improvement plan
Design inputs
Propeller diameter, hub dimensions, blade number, rotation direction, vessel type, operating speed range, material, classification and installation requirements.
Materials and quality
- Ni-Al Bronze Cu3
- Chemical composition analysis, surface inspection, dimensional verification, fitting checks and NDT per order
- ISO 9001 / ISO 14001 / ISO 45001; projects with DNV, ABS, RS, RINA, BV, KR, BKI and CCS
Applications
Cargo vessels, bulk carriers, tankers, container vessels, workboats and engineering vessels, and retrofit or replacement projects.
