MAN auto-tuning package landmark

This follows MAN PrimeServ selling its 100th Pressure Mounting Instrument (PMI) auto-tuning retrofit package. The system will be retrofitted to the MSC Filippa, a 13,400 teu container ship owned by Germany’s Peter Döhle Group.

Hagen Koslowski, technical director, Peter Döhle Schiffahrts-KG, said: “The main driver for us in ordering PMI auto-tuning was to reduce fuel consumption and therefore become more attractive to the charter market. Taking a broader view, the CO2 reduction and our environmental responsibility, paired with our trust in MAN products, also played key roles in the decision.”

The Peter Döhle Group has already installed the system aboard a series of 6,800 teu vessels – MV Pangal, MV Puelche and MV Petrohue, which are all equipped with MAN B&W 10K98MEC-7 low-speed engines.

PMI auto-tuning measures the pressure in a cylinder’s combustion chamber through online sensors. These automatically send signals in real time and the data is used to automatically adjust the cylinders for optimal performance. Adjustments can be seen on the CoCoS computer and MOP, keeping engine parameters at an optimal level.

MAN PrimeServ said that many owners of newbuild engines which have included PMI auto-tuning as standard have been inspired to retrofit the rest of their fleet with the system after observing its effectiveness in the field.
