MAN Energy Solutions’ after-sales service arm says upgrade to dual-fuel ready specification on MAN 48/60 engine types will make the older engines technical equivalents of newly-built MAN 51/60 engines
MAN PrimeServ said the upgrade enables customers to prepare older engines already in service for “future, climate-neutral operation”.
“Converted engines will effectively be equivalent technically to newly built MAN 51/60 units and, as a result, achieve significant savings in fuel consumption, CO2 and pollutant emissions, and increased reliability. As a further option, newly converted engines can be upgraded for operation on synthetic fuels for a low premium,” a statement from the company read.
“With this lifecycle upgrade, we offer customers the opportunity not only to completely overhaul their old engines but also to upgrade them to the latest engine technology at the same time. 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 future-proof investment,” head of MAN PrimeServ Germany Stefan Eefting said.
The company said future conversion to dual-fuel operation is made more straightforward with the upgrade, as 80% of all necessary adjustments are performed during the lifecycle upgrade.
MAN Primeserv said its MAN 48/60 engine types (variant A or B) already in operation, and which have more than 80,000 operating hours, are particularly suitable for a lifecycle upgrade.
MAN PrimeServ sales manager Marcel Lodder said, “Depending on the design of the engine – whether L or V – and the number of cylinders involved, a lifecycle upgrade can be carried out within 25 to 45 days – only about 30% longer than the time required for major maintenance. Due to the fuel and lube-oil savings from the upgrade and the elimination of ’ageing effects’, we expect our customers to see a return on their investment within 1.5 to 4 years.”
MAN Energy Solutions reports that calculations based on an exemplary business case have shown that upgrading a /60 engine to a /60 type can save around 500 tonnes of fuel and 25 tonnes of lubricating oil per annum – based on an annual operating time of 6,000 hours under full load.
MAN PrimeServ has already successfully completed the first lifecycle upgrade for a southern European customer, converting an MAN /60A power-plant engine with over 100,000 operating hours to a modern MAN /60 unit and will implement a further five lifecycle upgrades for the same customer by Q2 2023.
