New Dimension of Propeller
New Dimension of Propeller For more than 60 years, ship propellers from MMG have been setting new standards – in size, quality and efficiency. The key to our success are propellers that perfectly match the vessel, its engine and the purpose of the ship. As fuel prices are increasing, fleet owners are revising their requirements. The trend towards slow steaming has made propeller efficiency a top priority. Thanks to our dedication, professional approach and foresight, we have been able to step up to the challenge. Our new »Efficiency by MMG« label is reserved for propellers of the last generation that offer not only powerful propulsion but help protect resources, minimise CO2 emissions and reduce operating costs. With »Efficiency by MMG«, we respond to the ever more stringent environmental and fuel efficiency requirements for maritime vessels. Our objective: Making transport by sea as efficient and environmentally friendly as possible – now and in the future. All our activities – from the design department and the production floor to the sales office – are dedicated to this challenge.
At MMG, innovation has a long tradition. From the very first day, MMG has pursued a philosophy based on advanced technology. We are therefore always a ship‘s length ahead
Shaping the future
of our competitors. For more than 60 years, MMG has pushed the boundaries and set new standards in ship propeller design. MMG propellers drive the fastest container ship in the world, the largest double-hull tanker and the container vessel with the largest engine capacity. We are also the leading manufacturer of low-noise propellers made of high damping alloys for research vessels and navy ships. Based on our success in the past, we want to help shape the future of modern maritime propulsion technology.

Ship propellers from MMG are a striking sight. Our golden giants are not only extremely powerful but also very elegant in design.
Functionality is the benchmark
However, aesthetic considerations are of course of no concern to our propeller designers. All their efforts are focused on thrust and power. Sometimes, limited modifications are all that is needed to increase efficiency and reduce fuel consumption. In other cases, a new revolutionary design is required, especially in connection with new functions and uses of vessels. For our designs, we therefore do not only take into account the ship‘s hull and its engine, but also the envisaged operation profile of the vessel. It is our aim to come up with solutions that offer exceptional efficiency at fast and slow speeds as well as with full and partial loads.
Perfection in every detail
To implement innovative designs of our engineers, our production team must work to exacting standards. We therefore continuously invest in further training of our staff and
constantly upgrade our production processes. We operate the largest induction furnace for copper alloys and have invested in high-end machining centres that enable us to master even the most complex designs. Our computer-controlled five-axis mills guarantee highest precision in production. Experts use high end measuring instruments to prove the quality of our products. Only when the propeller meets our exacting standards is it assigned with the ÂťMade by MMGÂŤ mark. All production processes are completed under one roof in our 400 metre long production hall. This is not only highly efficient, but also provides the MMG propellers with a positive resource balance even prior to commissioning.
To stay ahead of the competition, we need to look far ahead. MMG pursues a multidisciplinary ap-

proach and cooperates with global partners. Together with other specialists, we solve complex problems and develop future-proof comprehensive solutions for the maritime industry. MMG is involved in numerous cooperation projects with universities, research institutes and certification bodies in the ship building sector all over the world. Among our partners are the Hamburg University of Technology, Rostock University, Hamburg Ship Model Basin (HSVA), Potsdam Model Basin (SVA Potsdam), the government-accredited training centre for welding SLV M-V GmbH and many more. In order to exploit potential synergies, we work closely together with leading ship-building companies who involve us from the very start when designing new vessels.
Acting today for a better tomorrow
Sustainable business practices ensure profitability in the future. We therefore take our responsibility towards society and the environment seriously.
Apart from economic aspects, we always consider the ecological impact of our activities. MMG is working hard to develop ever more efficient propellers in order to reduce greenhouse gas emissions and fuel consumption. In our production, we use technologies that help to protect resources. Our computerised energy management system allows us to optimise the efficiency of all our processes. We want to preserve our planet for future generations.
You can always trust MMG. We are with you on all the oceans of our world. Our customers can benefit from a comprehensive
Trust based on reliability
after-sales service pack. Our life-cycle management approach spans the entire service life of our propellers – installation; supervising; maintenance; modifications; as well as guidance or repairs in the event of damage. Of course our repair service also covers propellers made by other manufacturers. Should the operating conditions of vessels change, we will re-design the propulsion system accordingly to ensure optimum efficiency. Our re-design service does not only cover parts manufactured by MMG but the entire propulsion system, including rudders and shafting.

MMG – powering sea traffic on all oceans
No propeller is the same. Before coming up with a design, our engineers carefully analyse the envisaged use of the ship and its technical data. Based on detailed calculations and model trials, we then define the basic geometric shape of the propeller. Prior to production, every design is approved by the respective classification society.
The durability of a propeller depends heavily on the quality of the casting. That is why MMG carries out a number of simulation casting runs to analyse the casting and solidification processes. By using top-quality basic materials and accurate analysis equipment, we can achieve high-grade alloys that meet even the most stringent requirements. In our medium-frequency induction furnace – the largest and most modern in the industry – we produce flawless castings of the highest quality.
MMG uses high-precision, computercontrolled drillings and five-axis milling technology to convert the casting into a high-precision propeller. Even ship propellers of more than eleven metres in diameter can thus be machined with an accuracy of a few hundredths of a millimetre. The same precision is of course applied to the hub bore. Our specially designed balancing machine ensures that the propellers run perfectly true.
At MMG, state-of-the art machining technology goes hand in hand with true craftsmanship. The milled block is precision-ground for grinding manipulators. Sensitive sections such as the leading and the trailing edges are ground and polished by hand. Subsequently, each propeller is again carefully inspected and measured. Only if everything is exactly in accordance to design and specifications the propeller is approved with our quality seal.
The quality management system that ensures the high quality standards of our products and services is certified by Germanischer Lloyd in accordance to DIN EN ISO 9001:2008. In addition, MMG operates an environmental management system certified according to EN ISO 14001:2004 and is certified for occupational health and safety according to OH SAS 18001.
MMG is well known for its innovative solutions and designs. The »Efficiency by MMG« label has been specially devised to promote our latest generation of propellers that offer not only the propulsion necessary for large ships, but also significantly reduce the fuel consumption. With »Efficiency by MMG«, we respond to the ever more stringent environmental requirements for maritime vessels and the need to protect resources. Our objective: Making transport by sea as efficient and environmentally friendly as possible – now and in the future.
Since 1948, Mecklenburger Metallguß GmbH has been a major player in the development and production of ship propellers. Thousands of vessels equipped with MMG propellers are at the moment crossing the oceans. Among them are many ships that are the largest in their category. Whatever the future developments in the international maritime sector are: MMG will continue to produce propellers for tankers, bulk carriers, container ships and luxury cruisers that meet the requirements of their operators.
