Wärtsilä Propellers to Drive Greek Tankers
by the EnergoProFin. We place great value on being selected by this large and successful shipping company, which is an endorsement of Wärtsilä's propeller technology and evidence that fuel efficiency is still of great importance, even with the current low fuel prices," says Arto Lehtinen, Vice President, Propulsion, Wärtsilä Marine Solutions. Wärtsilä Fixed Pitch Propellers are based on OPTI Design methodology, which ensures optimum performance and minimum levels of noise and vibration. The result is a robust propulsion solution covering the full range

parameters of the propeller blades, by careful attention to the flexural modes of the propeller blades, and by careful attention to the specific geometry at the trailing edge of the blades. It has shown that all these aspects are interacting and can prevent the 'singing' of propellers," says Arto Lehtinen, Vice President, Propulsion, Wärtsilä Marine Solutions. Finite Element Method (FEM) analysis tools have been used in the identifying of the risk indicators related to the main propeller design parameters. By correctly adjusting these parameters, the response side risks can be minimised
