MAN Diesel & Turbo's retrofit concept consists of a broad range of solutions where our PrimeServ after-sales division applies the latest developments within diesel technology to engines in service, in the process bringing them up to current standards and meeting modern emission levels and lowering running costs. The concept applies to all MAN Diesel & Turbo engines (both marine and stationary), propellers and turbochargers. It can even be applied to engines from other manufacturers and has multiple benefits for engines, vessels and shipowners alike: 

  • Improved engine performance
  • Engines in service updated to modern standards
  • Longer time between overhauls

This includes such retrofits as the Alpha Lubricator, turbocharger retrofit and tailor-made slow steaming on requeest.
