Our Services

We offer you a maintenance concept tailored to fit your needs and ensure the safe, efficient, and reliable operation of your MAN engines, propellers and equipment worldwide. From inspection to overhaul and reconditioning of parts, to your individual service agreement, retrofit and training programs.

Inspection and documentation

Inspection on a regular basis and the associated documentation are essential for reliable operation. We offer inspections both in the workshop and on board vessels. In cooperation with the customer, a method description is prepared, which lists and describes all planned activities in connection with the order.

Prior to overhauls and repairs in the workshop, it is possible to have a pre-inspection carried out. This provides information on condition, machining recommendations, and which spare parts are recommended for replacement, and includes pictorial documentation of recommended repairs and replacements.

Afterwards, the responsible MAN PrimeServ technician describes in a detailed service report what was changed and repaired.

Retrofits and upgrades for a longer product lifetime

In order to extend the product lifetime and the time between overhauls, reduce CO2 emissions, and increase product performance, we at MAN Energy Solutions, together with our partners, offer retrofit solutions for all product categories. Retrofitting is possible for alternative fuels such as gas and electricity, but also for diesel. 

Popular examples:

  • Tier II retrofit: reducing NOx emissions.
  • Retrofit of turbochargers
  • Upgrading of exhaust gas purification systems
  • Upgrading of seals
  • Improving the life of valves and valve seats for low-sulfur operation
