Deutsche Bundesstiftung Umwelt (DBU): “For the Shipping Industry, This Is a Gyro Gearloose Moment”

Share

German Environmental Award for Energy and CO2 Reduction.

(Osnabrück, Germany): With their considerable ingenuity and entrepreneurial courage, the qualified engineers Friedrich Mewis and Dirk Lehmann have revolutionized the shipping world. With the Becker Mewis Duct (BMD), they have not only saved millions of tons of heavy fuel oil since its market launch in 2008, but have also saved around twelve million tons of the greenhouse gas carbon dioxide (CO2) which is harmful to our climate. The German Federal Environmental Foundation (DBU—Deutsche Bundesstiftung Umwelt) is honoring this innovative achievement with this year’s German Environmental Award, one of Europe’s most prestigious awards, which will be presented for the 30th time in 2022. The two engineers will share the total sum of 500,000 euros with the biologist Dr. Christof Schenck. President of Germany Frank-Walter Steinmeier will present the 2022 German Environmental Award in Magdeburg on October 30.

Interplay Between Cutting-Edge Research and Entrepreneurial Courage

DBU Secretary General Alexander Bonde says that it is extremely important to “bring the shipping industry in line with climate requirements”. After all, international shipping accounts for almost three percent of global greenhouse gas (GHG) emissions. This is more than 1.1 billion tons of CO2 equivalent. In comparison, according to the Federal Environmental Agency, Germany’s annual GHG emissions are 762 million tons. Bonde: “For the shipping industry, the BMD is a Gyro Gearloose moment.” The collaboration between the two engineers is a great example of how fruitful cooperation between cutting-edge research and entrepreneurial courage can be for product innovation. “And their invention, the Becker Mewis Duct, is truly a win-win. It will save fuel, and thus energy, for the shipping industry. Above all, however, it is good for the environment, as it reduces the pollution of greenhouse gases.” In fact, it is calculated that the BMD has saved around twelve million tons of CO2 since 2008—corresponding to approximately the annual CO2 emissions of Tanzania or Hamburg. Bonde explains: “The key factors here are the increase in efficiency brought about by the Becker Mewis Duct and the positive impact on the environment. These will both persist—even if the shipping industry eventually moves to other, more environmentally friendly, fuels in place of heavy oil.”

Professional Experience, Inventions and Numerous Patents

The collaboration between Mewis (79) and Lehmann (58) dates back to 2001. Mewis had already made a name for himself as an innovator in shipbuilding, while Lehmann was the new head of the medium-sized maritime company Becker Marine Systems based in Hamburg, of which he is still a managing director today. Mewis, who was born in Wittenberg, once home to Martin Luther, in 1943, first worked at the Potsdam shipbuilding research institute after studying shipbuilding, before moving to the Hamburg shipbuilding research institute in 1996, a few years after reunification. After retirement, Mewis continued to work from Dresden as a consultant for shipowners, shipyards and shipbuilding suppliers, and has almost a dozen patents in his name. Lehmann is a proud Hamburger and also has numerous patents. In addition to his main job, he is a shareholder in start-ups working in electric and hydrogen mobility. He is also involved in several organizations, including as Vice-Chairman of Sea Europe, the shipyards’ and maritime equipment association of Europe.

Emergence of a Dazzling Idea

While Mewis and Lehmann initially focused on enhancing rudders for very large container ships, they began working more intensively on other areas from 2007 on. It all came down to the question of how the efficiency of large, slow, “full-form” ships could be increased—from tankers to bulkers, in other words bulk carriers for ore, grain, and other materials. Container ships were subsequently also added. Mewis: “All the technical tricks had actually already been invented.” At some point, however, he came up with a dazzling idea—to combine different, already existing, components. The Becker Mewis Duct was thus born—a hydrodynamic energy-saving duct positioned in front of the propeller, or an “energy-saving device”, as it is referred to in technical speak. Weighing up to 60 tons, and with a diameter of up to seven meters, it is produced in two halves that are welded together on the ship. Lehmann believed strongly in this invention, pressed ahead with it with great passion, convinced doubters, and overcame the necessary red tape. This is how he explains the BMD in layman’s terms: “A ship is like a shoe box being pushed through the water. At the front, there’s a wave, and at the back, the water doesn’t know where to go.” Mewis set his sights on this “wake field”. Lehmann: “It’s like cutting a yogurt pot crosswise and positioning it behind the box as a funnel—and in front of the propeller. This bundles the water together.”

Increased Environmental Protection Through Technological Advancements

As a technical refinement, asymmetrical flow-guiding parts, known as fins, were integrated into this front duct. In short: the working principle for the Becker Mewis Duct. Lehmann: “The result is a negatively generated swirl in the opposite direction to the propeller rotation.” This is the prerequisite for the Becker Mewis Duct to ensure more effective ship propulsion, to reduce the consumption of heavy fuel oil by up to ten percent, and thus to protect the environment from greenhouse gases. A positive side effect: quieter ships and thus less noise pollution for marine life such as whales. The Becker Mewis Duct has so far been installed in 1,400 vessels worldwide, with 300 more soon to follow. The two award winners regard the German Environmental Award as a “great honor”. Lehmann also hopes that politicians will put “zero emissions in the shipping industry at the top of the agenda”.

R-Biopharm AG: Flu tests from R-Biopharm also detect new virus variants25.11.2022 11:23:27 CET | Press release

Darmstadt, November 25, 2022: The flu season has begun and different virus variants are also circulating in Germany. With the flu tests from biotechnology company R-Biopharm, patients quickly have certainty: Its RIDA®GENE Flu assays also reliably detect the two novel variants. The company made the announcement with regard to influenza A H1N1pdm09, which is circulating primarily in the United Kingdom, and the H3N2 subtype, which was rampant in Denmark in the spring and is currently dominating influenza activity in Germany. "Mutations in the target gene (MP gene) can affect the diagnostic performance of influenza screening assays, producing false-negative test results," explains Dr. Andreas Simons, Head of Product Management at R-Biopharm. " Alignments of the detection systems we used with the described sequences of the two novel virus variants showed no mismatches. Their reliable detection is not affected by the described mutations." This means laboratories can continue to reliably conf

The high-performance single-seater 777 hypercar is born in Monza22.11.2022 11:05:00 CET | Press release

(Monza, Italy): – The 777 hypercar is a new Italian hypercar born of the excellent partnership with Andrea Levy, Dallara, and Gibson, built from technology used in motorsports and all informations and images are on www.777hypercar.com. 777 hypercar is built by 777 Motors, the car manufacturer based in the Autodromo Nazionale Monza and founded by Andrea Levy, an entrepreneur, car collector, racing driver, and president of MIMO Milano Monza Motorshow. The 777 hypercar project will be presented on November 22, limited to just 7 units, each of which will cost 7 million euros. 777 hypercar is at the top for performance thanks to an FIA-homologated carbon monocoque developed by Dallara, which generate an incredible downforce of 2,100 kg at a speed of 370 km/h, an extremely low weight of 900 kg, and a lateral acceleration from 3.5 to 4 g that keeps the car glued to the asphalt, giving an incredible estimate lap time of just 1 minute and 33 seconds in the Monza Circuit. The engine is a natural
