MAN Diesel & Turbo SE has delivered four MAN 12V175D generating sets to Fincantieri Muggiano Shipyard, where the first of a class of seven multipurpose offshore patrol vessels (PPA) for the Italian Navy is currently under construction.
This application means the engine is “now available as a fully qualified and referenced product” for the defense market, the company said.
The MAN 12V175D gen-sets for the PPA class are specifically designed for navy applications and incorporate a double elastic mounting layout designed to fulfill strict vibration and shock requirements. Two of the gen-sets are equipped with a high-performance noise enclosure designed to provide a very low acoustic signature and MAN’s designed selective catalytic reduction (SCR) exhaust after-treatment systems, already compliant with the latest IMO Tier 3 emission regulations.
“MAN Diesel & Turbo SE is proud of having contributed with the MAN 175D to such an ambitious and technologically advanced fleet renewal program,” Lex Nijsen, head of Four-Stroke Marine. “The close cooperation with Fincantieri and the Italian Navy has been the key factor for a successful project and has laid the foundation for securing the order for the second shipset.”
Italy’s Programma di Rinnovamento Navale is a major fleet renewal project that will comprehensively modernize the Italian fleet, allowing a number of older vessels to be retired in the process. MAN Diesel & Turbo SE has also won the order to supply main and auxiliary engines for a logistics support ship (LSS) and landing helicopter dock (LHD).
MAN Diesel & Turbo’s scope of supply for the LSS covers two 20V32/44CR main engines (delivering 12 000 kW each) for diesel-mechanical propulsion and four 6L27/38 gen-sets (delivering 2084 kW each). The scope of supply for the LHD is two 20V32/44CR main engines (delivering 12 000 kW each) and four 9L32/44CR gen-sets (delivering 5,00 kW each). MAN Diesel & Turbo will also supply its in-house-designed SCR system for the auxiliary engines.
With the MAN 175D engine, MAN Diesel & Turbo SE complements its marine product portfolio with a powerful high-speed engine in the power range from 1,500 to 2,200 kW. Typical applications include ferries, offshore supply vessels, tugs, working boats and naval vessels. In combination with the MAN own-designed SCR after-treatment system, the MAN 175D already fulfills the latest IMO emission regulations. Since 2014, MAN 175D propulsion and gen-sets solutions have proven their superior efficiency and reliability with thousands of operating hours in several applications.
