Small cap. Big impact.

The innovative Energy Saving Cap (MMG-escap®) from MMG enables ship owners to increase the efficiency of their propulsion system by up to 3 %. In contrast to conventional propeller caps, the MMG-escap® has an elaborate fin design. It straightens the hub vortex and reduces torque loss. The MMG-escap® is not just suitable for new propellers. It is also the ideal solution for making existing propellers more efficient. And because the investments required are manageable, the return on investment can be achieved in less than three months.


An investment with multiple pay-offs

As model tests show, the average saving potential for a 7,000 TEU container ship running between Asia and Europe with the Energy Saving Cap is approx. 3 %. With a vessel speed of 17 knots and a price for IFO 380 of 600 USD per ton the operating costs for an Asia round trip will be reduced by USD 96,000. This is how the return on investment, for example, is achieved in less than 3 months. Another significant benefit: the optimised flow behaviour reduces cavitation on the rudder and hull, reduces wear and tear and, thus, increases the service life time of the vessel.


Fast installation. Global service.

Whether as a retrofit for an existing propeller, in combination with a redesign or as an extra for a new propeller on a new ship – MMG assembles the MMG-escap® quickly and all over the world.
