Propeller re-blading

Propeller design techniques continue to improve, and when a vessel has been in service for some time it can often pay to invest in a new set of propeller blades.

Due to advances in hydrodynamic analysis and blade manufacture the new blades will be more efficient than the old ones, which will also be suffering from normal wear and tear. If the vessel has changed its operational profile the gains can be even higher.

Rolls-Royce has carried out numerous reblading jobs that have resulted in substantial reductions in fuel consumption and short payback times, with a subsequent reduction in emissions. An added bonus is usually a reduction in vibration and propeller induced noise.

Ships are studied to see if new propeller blades will pay off – contact your local Rolls-Royce service centre if you have a candidate vessel and determine the potential savings.
