MAN Energy Solutions has announced an order for 16 of its MAN 175D four-stroke engines, in connection with the building of four corvettes - known as the Squadron 2020 project - for the Finnish Navy, with each ship powered by a diesel-electric plant, centred on four MAN 12V175D-MEL gensets, with a total output of 7,700 kW, driving twin ice-strengthened CP propellers.

Jyrki Heinimaa, CEO Rauma Marine Constructions, which is building the corvettes, said: “Due to COVID-19, the negotiations were challenging and required additional effort and patience from both parties. RMC has good experience in working with MAN and looks forward to continuing the cooperation for the Squadron 2020 project from Augsburg.”

Ben Andres, Head of High-Speed Sales, MAN Energy Solutions said: “This is a very welcome order that owes much to our broad experience with the 175D engine in the naval sector, and is the latest in a series of demanding and varied naval orders that we have landed. In this particular instance, the MAN 175D’s technical and economical credentials stood it in good stead, while its compactness, shock capability, and best-in-class fuel-oil consumption were also key criteria for the customer. Integrated Logistics Support (ILS) for the power systems will ensure efficient and cost-effective maintenance throughout their entire service life.”

The first test-runs at sea are scheduled for 2024 with all vessels projected for completion by 2028.

The MAN 175D gensets bound for Finland will feature double-elastic seating, with a number of the gensets inside noise enclosures for silent operation.

MAN says that its 175D is the only high-speed navy genset able to reach the required power level with 12 cylinders, which makes it more compact and more effective in terms of maintenance. The engines will be suitable for arctic operation and capable of functioning in extremely low air-intake temperatures.

The Squadron 2020 project aims to replace seven older vessels; the four modern corvettes will then form the backbone of the navy into the 2050s. The overall length of the Pohjanmaa-class corvettes is 114m, with a beam of 16m and maximum draught of 5m – corresponding to a displacement of some 3,900t.
