Introduction of an optimal propeller rudder arrangement

摘要

Van der Velden Marine Systems and Mecklenburger Metallguss GmbH (MMG) have entered a partnership, which has resulted in the development of a highly effective and efficient propulsion package: the Energy Saving Package. The Energy Saving Package consists of a tailor-made propulsion package which meets the customer's requirements. MMG and Van der Velden* combine the advantages of an optimised, efficient fixed pitch propeller with an asymmetric leading edge rudder with a propulsion bulb and adapted hub caps. Due to rising fuel costs and the highly competitive ship market, ship owners and charterers require efficient and fuel saving operation of their ships. Together with the ship owner, the naval architect and/or the yard, front end engineering design (FEED) will identify the needs according to the ship's operational profile and optimise the propeller rudder-arrangement depending on the particular criteria, such as fuel efficiency, good and effective manoeuvrability, minimising cavitations and vibration, and low maintenance effort, eventually resulting in an optimised propeller geometry and a slip stream adapted rudder geometry.
