MAN Energy Solutions’ new MAN 49/60DF four-stroke engine has been approved by six classification societies after successfully passing a five-day programme of type approval tests (TAT) at MAN ES’s Augsburg facility in Germany in March 2023.

The Type Approval Test (TAT) was witnessed by inspectors representing the ABS, BV, CCS, DNV, LR and RINA classification societies, who signed the test protocol upon the successful completion of the schedule.

 The most recent addition to its four-stroke engine portfolio, the dual-fuel engine is capable of running on LNG, diesel and HFO as well as a number of more sustainable fuels including biofuel blends and synthetic natural gas.
