Founded in 1992 by João Coelhoso, CMN began operations with the aim of providing specialist solutions in metalworking and industrial maintenance. By 2007, international experience and the development of qualifications and certifications had led to a strategic restructuring of its business areas. This reorganisation resulted in CMN specialising in LNG (liquefied natural gas) tanks, consolidating its position in a highly technical and demanding sector.
