Russia’s largest shipowner, Sovcomflot, has chosen dual-fuel MAN 51/60DF engines for an LNG carrier newbuilding programme comprising two firm newbuilding orders with an option for two further vessels.

According to MAN Diesel & Turbo, the dual-fuel diesel electric propulsion system with MAN 51/60DF prime movers have been selected to provide high efficiency in a low-emission propulsion system, especially when running in gas mode. A high degree of redundancy and the MAN 51/60 DF engine’s multiple fuelling options have been taken into account.

The ships are currently under construction at STX Offshore & Shipbuilding in South Korea and will each be driven by sets of two 8L and two 9L51/60DF engines. The engines will be built at the Augsburg plant in Germany with delivery to the Korean yard due in the fourth quarter of 2012. The first vessel is expected to enter commercial operation in the fourth quarter of 2013.

MAN says that this latest 51/60DF orders marks another milestone in its strategy of expanding its environmentally friendly dual-fuel-engine technology into the marine sector. The first 51/60DF order for a marine application was signed in 2007 for an LNG Carrier – Castillo de Santisteban – with five 8L51/60DF units owned by Spanish shipowner Empresa Naviera Elcano. This vessel has successfully operated commercially since summer 2010 in transporting LNG worldwide.
