Optimising your operational fleet.
Up to 14 % fuel saving.

Overcapacity, falling cargo rates and rising fuel prices have been putting pressure on maritime trade for years. Many ship owners are already using slow steaming to reduce fuel costs and bring more ships in charter. Many shipping companies have now fully exhausted the potential savings of reduced speed with the existing technology. MMG redesign offers additional saving potential. Swapping the ship‘s propeller for one aligned with the new operating profile increases efficiency and reduces consumption. In combination with the MMG-escap®, ship owners can achieve fuel savings of up to 14 percent. An additional plus: MMG rebuys the old propeller. Thus, the return on investment is achieved in just six months.

For a secure investment: Model test reviews saving potential

MMG performs extensive calculations to determine the achievable saving potential of the redesign programme for every ship. We are the only propeller builder able to incorporate over 2,000 operating points thanks to our Multidata Design Concept (MDC) – from real-life ship speeds to weather and load conditions. We test the predicted saving potential with our Numerical Propulsion Simulation (NPS). Model tests performed at ship model basins confirm the NPS results.

Perfection down to the last detail.

MMG is setting new standards in production precision with digitally optimised 5D Propulsion to exploit the potential of the design to the full scale. The firm has the largest induction furnace in the world for copper alloys, computer-controlled five-axis milling machines and high-end machining centre, facilitating an array of production possibilities for ship propellers. Experts use the latest measuring techniques to monitor quality. The propeller is only delivered once everything is perfect.

Quick replacement. Complete service.

MMG has developed the Virtual Contact Test (VCT) to ensure that propellers can be replaced within one docking interval. With VCT the conical hub bore is measured precisely down to a hundredth of a millimetre and aligned with the design data of the existing shaft while still in the MMG works. The MMG engineers will test the dimensions of the ship’s shaft using a mobile measuring unit if required.

The VCT makes the traditional spot check for fit accuracy between the propeller and shaft cone fully superfluous.

MMG also offers extensive services after fitting. Whether supervision, modification, consultation or repair after an accident – LifeCycle Management applies for the entire service life of the propeller. You can rely on MMG. On all oceans. That’s »Efficiency by MMG« too.
