OCTOBER 30, 2016 — MAN Diesel & Turbo has won a breakthrough order for its 175D high speed engine, winning the contract to supply the first shipset (plus an option for six more, to be confirmed) of gensets for the Italian Navy's multipurpose, offshore patrol vessel – Pattugliatore Polivalente d' Altura (PPA) – program.

Each vessel will feature 4 × 12V175D GenSets, each delivering 1,640 kW. The newbuildings 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.

"The MAN 175D is compact, reliable and efficient - properties that are of essential importance for use on working vessels to allow safe maneuverability in the most challenging and roughest weather conditions," said the Project Lead responsible for the MAN 175D, Dr. Matthias Schlipf. "The business case behind it also has to be right for the customer. And this is where the engine sets standards in more than just fuel consumption. Our aspiration is to make the MAN 175D the overall most efficient engine throughout its lifetime."

The MAN 175D also scores highly in terms of 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 IMO Tier III requirements, while its compact dimensions and low weight make the MAN 175D an efficient powerhouse."

ORDERS FOR LSS AND LHD

MAN Diesel & Turbo has also won the orders to supply main and auxiliary engines for two more Italian navy vessels, a logistics support ship (LSS) and a landing helicopter dock (LHD). Its scope of supply for the LSS covers two 20V32/44CR main engines (delivering 12,000 kW each) for diesel-mechanical propulsion four 6L27/38 gensets (delivering 2,084 kW each).

For the LHD, the scope of supply is two 20V32/44CR main engines (delivering 12,000 kW each) and four 9L32/44CR gensets (delivering 5,400 kW each).

MAN Diesel & Turbo will also supply its in-house-designed SCR system for auxiliary engines.
