MAN PrimeServ, MAN Diesel & Turbo’s service division, has announced the 100th sale of its PMI (Pressure Measuring Instrument) Auto-tuning retrofit package. The ‘MSC Filippa’, a 2011-built, 13,400-teu container ship owned by Germany’s Peter Döhle Group, will be retrofitted to accommodate the system. Hagen Koslowski, Technical Director of 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 previous experience with PMI Auto-tuning, having recently installed it aboard a series of 6,800-teu vessels – MV ‘Pangal’, MV ‘Puelche’ and MV ‘Petrohue’ – equipped with MAN B&W 10K98MEC-7 low-speed engines. Of their experience with this, Koslowski said: “On all our vessels, the system runs reliably. The PMI works really well and adjustments can be seen on the CoCoS computer and MOP, while engine parameters are always at the optimal value.” Koslowski also praised an “outstanding performance” by MAN PrimeServ’s service engineers who installed, commissioned and pre-adjusted the PMI Auto-tuning system aboard the container fleet.
He added: “With the PMI system in place, we observed an SFOC drop on our engines using Bluetraker® performance monitoring. In the long term, our main expectations are extended TBOs and a smaller workload for our crews as engine performance will be permanently, automatically optimised.
Autotuning PMI Autotuning 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. The system replaces the older PMI Offline and Online systems.
