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.”
Previous experience
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 lowspeed 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.
Christian Ludwig – Head of Retrofit & Upgrade – MAN Diesel & Turbo, said:
“We introduced our first PMI Autotuning system in 2010 as a result of the
possibilities arising from the launch of MAN Diesel & Turbo’s electronic MEengines in 2005. The strong sales performance of our Autotuning package
shows how successfully the market has taken to it. So much so, in fact, that
we recently decided to make it standard on our newbuilding engines.” In fact,
MAN PrimeServ reports that many owners of newbuilding engines that have
featured PMI Autotuning as standard have been inspired to retrofit the rest of
their fleet with the system after observing its effectiveness in the field.
Ludwig also states that the next development within PMI Autotuning is ‘PMI
VIT’ for its MC engines. MAN Diesel & Turbo introduced the first prototype
system in 2013 that uses PMI data to adjust the VIT (Variable Injection
Timing) system to get an optimal combustion pressure. Ludwig said: “With
PMI VIT, we are addressing our sizable, mechanical MC-portfolio of engines
and aiming to emulate that which PMI Autotuning has achieved with electronic
engines.”
Benefits
PMI Autotuning offers a number of advantages:
•
confirmed fuel savings of 1-3 g/kW
•
contributes to engine safety by eliminating excessive cylinder
pressures
•
offers better combustion with less stress to the engine and a
commensurate reduction in maintenance
•
real-time surveillance that reduces engine maintenance.
