German engine maker Everllence (formerly MAN Energy Solutions) has completed what it hails as “the world’s first” conversion of its two-stroke engine to dual-fuel methanol running, following the sea trials wrap-up of a 20,000 TEU containership owned by China’s COSCO Shipping Lines.
As informed, the vessel in question is the 200,000 dwt COSCO Shipping Libra. The conversion involved the Everllence B&W S90 two-stroke engine, i.e., the retrofitting of the seven-year-old ship’s 11S90ME-C engine to an 11S90ME-LGIM (-liquid gas injection methanol) unit.
