RETROFIT – LNG / DUAL-FUEL / exhaust gas and ballast water purification systems

Fit for the future
We take on all tasks required for the retrofitting of engines and propulsion systems.

LNG conversion, Scrubber installation and exhaust gas and ballast water purification systems
In green-shipping concepts, the conversion to LNG (Liquified Natural Gas) plays an important role as an alternative fuel concept. Thanks to our unique experience with gas engines, we are able, together with our Excellence partners German Dry Docks and BREDO Dry Docks, to implement solutions which are absolutely convincing, both ecologically and economically.

This also applies to retrofitting with modern exhaust gas scrubbers. Our more than 60 years of experience in engine and service forms, together with the expertise of the Excellence Partner Network, the basis for future-oriented solutions.

An additional business segment is retrofitting with ballast water treatment systems, which can be carried out together with other services of MWB Marine Services or partners. 


MWB Marine Services is your reliable service partner for the new installation of diesel and gas engines as well as exhaust gas and ballast water purification systems. For this task, we are well prepared in every respect and will be glad to advise you – from conception to commissioning.
