The Becker Mewis Duct At first glance, the Becker Mewis Duct is a relatively simple piece of equipment, consisting of a duct containing a number of integrated angled fins. of propeller and characteristic parameters of the Mewis duct. Current CO 2-Savings by Mewis Duct ®. A bulk carrier running at 14 knots per hour would have exhausted 29. The Becker Mewis Duct® is a highly-efficient energy-saving device developed, manufactured and distributed by Becker Marine Systems. Our Diver/Welders hold AWS D3. The use of all Becker Mewis Ducts delivered to date have already lowered emissions of CO2 by more than 2. For a 38,000-t bulk cargo ship, a wide range of duct loca-tions, duct radius, and angle of attack of the inner fins were. The Becker Mewis Duct is reinforcing the aim of attaining greater sustainability in the global shipping industry. As a model basin and research institute, the SVA Potsdam has the unique advantage of being able to use the experience gained from basic and applied research directly for the design of propulsion systems. 2 million t (October 2017). 0 m • 105,042 DWT Its Becker Mewis Duct® (retrofitted 2012) reduces CO2 by 1,574 t per year 858 Becker Mewis Ducts® have reduced CO2 by > 4. THE BECKER MEWIS DUCT® At first glance, the Becker Mewis Duct® is a relatively simple piece of equipment, consisting of a duct containing a number of integrated angled fins.

MODULE 4 Ship-Board Energy Management Module Aims and Learning Objectives This module is intended to provide the awareness, knowledge, skills and motivation required of ship-board and office-based staff on ship-board energy management techniques and activities. Prime Tanker Management supplied brand new MEWIS-duct parts which were installed in the Yard. The Becker Mewis Duct is a smart and economic way to considerably reduce CO2 and NOx emissions from our customers' fleets. Well savings from a Mewis Duct is from zero to maybe one tonne of fuel. The reasons for this are. Compared to using on-board diesel engines, power supplied by the LNG Power Barge will lead to a dramatic reduction of harmful CO 2, NO X, SO X and particle emissions during layovers in port. Following its appearance at Nor-Shipping, the 1,000th duct is to be fitted onto a 22,000 cubic-metre LPG carrier. ICE Class, strenghten for heavy cargoes, mewis duct fitted. Furthermore, advanced painting scheme by International and AkzoNobel, applied in vessel's hull. The high-tech energy-saving system, the Becker Mewis Duct®, created by Becker Marine Systems, is a pre-swirl propeller duct and reduces fuel consumption by approximately 3-5% on each vessel, resulting in the same level of CO2 emissions reduction. - and even more for retrofit upgrade solutions. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. of propeller and characteristic parameters of the Mewis duct.
