Wider in Italy has selected a pair of MAN 12V175D-MEV marine variable-speed genset engines for its new Moonflower 72 Project. The Wider serial hybrid propulsion system is made up of two 1,860 kW-rated variable speed engines and 1 MWh battery bank.In combination with the permanent magnet alternators providing electric power for a DC grid, the MAN 175D engines are ideal for guaranteeing the lowest fuel-consumption at variable speed. Both engines will be supplied along with MAN Energy Solutions’ versatile and efficient SCR exhaust gas after-treatment system, enabling the vessel to meet IMO Tier III emission standards.MAN Energy Solutions production facility in Denmark will deliver the engines to Wider in April 2023.MAN Energy Solutions has developed the MAN 175D engine range to supplement and complete its product portfolio in the maritime sector. In three variants of 12, 16 and 20 cylinders, the engine is available with an output ranging from 1,500 to 4,400 Kilowatts and is optimised for propelling ferries, offshore support ships, tugs and other working vessels. Other market areas, such as superyachts, planing yachts and naval marine applications are also served by additional engine variants.It is also an extremely eco-friendly engine, having been designed from the outset with a combination of low fuel-consumption, coupled with compliance with the latest exhaust-gas emission standards. It also takes into consideration future requirements by utilising a very compact and flexible SCR system, which enables vessel designers to optimise space on board to the maximum.Shortly after, Wider opened a site in Ancona, in the port’s industrial area. The shipyard pioneered the introduction of hybrid-electric technology for the propulsion and "hotel" services of its yachts. This technology remains unsurpassed to this day and has been successfully implemented on two yachts – a 45-metre yacht that has been sailing since 2015 and a 52-metre yacht launched in 2019.
