Wärtsilä Coastal and Inland Waterway Propellers
Custom-designed fixed pitch propellers, nozzles and shaft assemblies for inland waterway, coastal, fishing, yacht and government vessels; bronze or stainless steel, 3–7 blades.
Description
Wärtsilä Coastal and Inland Waterway Propellers are fully optimised, non-standard fixed pitch propeller designs for vessels on local waterways and coastal and fishing vessels, as well as large luxury yachts and governmental and special vessels. Designs account for varying operating conditions such as changing draft with water levels, and cavitation and pressure pulses are simulated under varying conditions – also for vessels lacking wake field or resistance data.
Key features
- Bronze or stainless steel
- Tailor-made with 3, 4, 5, 6 or 7 blades
- Accuracy to ISO class II, I or S
- Fixed pitch propellers for any diameter above 1000 mm; in this segment seldom larger than 3500 mm
- Supplied with nozzles, propeller shaft assemblies and stern tube systems
- Optional Wärtsilä High Performance (HP) nozzle for increased bollard pull and sustained vessel speed
- Optimised for maximum efficiency with minimum noise and vibration
Applications
Inland waterway and coastal vessels, fishing vessels, large fast luxury yachts (e.g. the 83 m yacht Samar), government-owned ships and special vessels.
