MAN D&T announced that it has won the contract to supply the first shipset (plus an option for six more, to be confirmed) of GenSets for the multipurpose, offshore patrol vessel – Pattugliatore Polivalente d‘ Altura (PPA) – program. Each vessel will feature 4 × 12V175D GenSets, each delivering 1,640 kW. The new buildings have been ordered as part of the Italian Navy’s “Programma di Rinnovamento” – fleet renewal, a major project that also features other vessels with MAN technology.
Lex Nijsen, Head of Four-Stroke Marine, MAN Diesel & Turbo said: “We already have several 175D test installations in operation but this is really the breakthrough for the engine. Its excellent performance data and fuel consumption figures have created huge interest in the market and we are looking forward to following its development.” MAN Diesel & Turbo reports that the new GenSets were chosen for their highly reliable and fuel-efficient design that meets the multiple scenarios and demands that such patrol vessels encounter.
Fincantieri, one of the world’s largest shipbuilding groups and reference player in naval shipbuilding, will build the ships in Italy. Delivery of the first vessel is scheduled for 2021, with subsequent deliveries in 2022, 2023, 2024 (two units) 2025 and 2026. The PPAs are highly flexible vessels with the capacity to serve multiple roles, ranging from patrolling with sea-rescue capabilities, to civil protection and – in its most highly equipped version – as front-line fighting vessels.
Each PPA is 133 m long between perpendiculars, has a top speed of over 32 knots, and can host a crew up to 180 persons. The MAN 175D GenSets will, on account of the demanding operating conditions, feature double-elastic mounting and, in the Aft Machinery room only, sound enclosures. In addition to the engines and their related plant equipment, MAN Diesel & Turbo will also supply, in the Aft Machinery room only, its in-house-designed SCR system to ensure an environmentally friendly footprint.
“Programma di Rinnovamento”
“Programma di Rinnovamento” is a major fleet renewal project that will comprehensively modernise the Italian fleet, allowing older vessels to be retired in the process. MAN Diesel & Turbo has furthermore won the order to supply main and auxiliary engines for a logistics support ship (LSS) and landing helicopter dock (LHD). The engine manufacturers scope of supply for the LSS covers 2 × 20V32/44CR main engines (delivering 12,000 kW each) for diesel-mechanical propulsion + 4 × 6L27/38 GenSets (delivering 2,084 kW each). The scope of supply for the LHD is 2 × 20V32/44CR main engines (delivering 12,000 kW each) + 4 × 9L32/44CR GenSets (delivering 5,400 kW each). The engine company will also supply its in-house-designed SCR system for auxiliary engines.
About the MAN 175D Engine
MAN Diesel & Turbo developed the 12-cylinder model to supplement and complete its product portfolio in the maritime sector. The new engine is available with an output spectrum from 1,500 to 2,200 Kilowatts and is optimised for propelling ferries, offshore supply vessels, tug boats and working vessels. Other central areas of application such as the markets for super-yachts and marine applications are served by additional, specialist model versions. According to the engine maker scores the 175D also highly in terms of its eco-friendliness: Its compact and modular exhaust gas after-treatment system uses the selective catalytic reduction (SCR) method and is based on the MAN Ad Blue® technology that has undergone many thousands of hours of testing. The engine therefore satisfies the strict environmental standards of the IMO Tier III, while its compact dimensions and low weight make the engine an efficient powerhouse.
