Wärtsilä Ship Propeller Solutions
Wärtsilä propeller portfolio: controllable pitch (CPP), fixed pitch (FPP) and built-up propellers, plus EnergoProFin, EnergoFlow and OPTI Design efficiency solutions for a wide range of vessel types.
Description
Wärtsilä ship propeller solutions cover fixed and controllable pitch propellers and related efficiency devices, matched to the vessel type, operating conditions, propulsion power and shaftline requirements.
Portfolio
- Controllable pitch propellers (CPP): blade angle adjustable in operation for varying conditions; suited to ferries, short sea ships, trawlers, icebreakers and dredgers
- Fixed pitch propellers (FPP): no blade actuation system, the most robust type; common on container vessels, tankers, bulk carriers and dry cargo vessels
- Built-up propellers: blades replaceable under water, for vessels with frequent risk of propeller damage
- EnergoProFin: propeller cap with fins rotating with the propeller; average fuel savings of 2% with payback under one year
- EnergoFlow: pre-swirl stator optimising propeller inflow; propulsive efficiency improvement of 2–7%
- OPTI Design: CFD-based methodology matching propeller, engine and hull
Services
Maintenance, inspections, repairs and lifecycle upgrades are available worldwide.
