ESPAC™ Rudder of 97m2 for 16.000 TEU MARIC Design for CMA CGM
21 October 2013
Van der Velden Marine Systems designed and manufactures ESPAC™ (Energy Saving Package) rudders for the largest container ships ever designed and built in China. The series of three vessels will be built by CSSC-affiliated Shanghai Waigaoqiao Shipyard (SWS), and the first delivery is scheduled in September 2015.
With an area of 97m2, these will be the largest rudders built by our company to date. The ESPAC™ design, asymmetric with a Van der Velden Bulb, is an integrated rudder-propeller solution developed in cooperation with propeller maker MMG. The propulsion package has proven significant fuel saving during the tank test carried out at MARIN. The MMG propeller has a diameter of 10 meters.
The 390 meter long vessels are designed by the Shanghai based Marine Design & Research Institute of China (MARIC) in accordance with the latest environmental regulations. Their fuel consumption is 30% less compared to existing vessels of the same size. They will be operated by French Line CMA CGM in the trade between Asia and Europe.
Efficiency by MMG in cooperation with Van der Velden® Marine Systems
Van der Velden Marine Systems and Mecklenburger Metallguss GmbH (MMG) have founded a partnership to combine their knowledge and develop a highly effective and efficient propulsion package.
The ESPAC™ (Energy Saving Package) consists of a propulsion package which is tailor-made to meet customer requirements. MMG and Van der Velden combine the advantages of an optimised, highly efficient fixed pitch propeller and an asymmetric leading edge rudder with a propulsion bulb and adapted hub caps.
