MAN PrimeServ, the after-sales brand of MAN Energy Solutions, has announced that it can now retrofit older MAN 48/60 marine engines to MAN 51/60 types as part of the company’s new lifecycle upgrade.
The upgrade enables older engines to be prepared for future climate-neutral operation. Furthermore, future conversions to dual-fuel operation can be undertaken because 80% of all necessary adjustments and changes are made during the lifecycle upgrade. Newly converted engines can also be upgraded to run on synthetic fuels.
Calculations carried out by MAN Energy Solutions based on an exemplary business case have shown that by upgrading a 9L48/60 engine to a 9L51/60 type, users could save approximately 500 tons of fuel and 25 tons of lubricating oil each year – based on an operating time of 6,000 hours under full load.
“With this lifecycle upgrade, we offer customers the opportunity to not only completely overhaul their old engines but also upgrade them to the latest engine technology at the same time,” said Stefan Eefting, senior vice president and head of MAN PrimeServ Germany. “The upgrade simultaneously prepares the engines for future operation with climate-neutral fuels without having to change the fuel type they use at this stage. This is because the 51/60 engine type enables further conversion to alternative fuels, making it a futureproof investment.”
