Wärtsilä 32

The Wärtsilä 32 was developed in response to a need in the market for a new engine in the 320 mm cylinder bore class and since 1998 more than 2500 of these engines have been sold to the marine market, in total more than 4500 Wärtsilä 32 bore engines have been delivered to the marine market since the 1980s.

Based on the latest achievements in combustion technology, it is designed for efficient and easy maintenance in combination with long maintenance-free operating periods. The engine is fully equipped with all essential ancillaries and a thoroughly planned interface to external systems.

The Wärtsilä 32 engine is fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention.


    Exellent fuel flexibility allowing operation on HFO, LBF, MDO and ultra low sulphur fuel. Low fuel oil consumption over a wide load range.

    Utmost power-to-weight and power-to-space rations in combination with a great flexibility in engine support arrangements allows optimised rigid or flexible installation for a wide range of vessel applications.

    Fast starting times and great load acceptance makes the Wärtsilä 32 a preferred choice in many offshore applications.

    High reliability and proven in service makes the Wärtsilä 32 an excellent choice for any application.

    The Wärtsilä 32 can be installed in a vast range of applications such as drillrigs and ships, AHTS, PSV, dredgers, Fishing vessels, Tugs and Ferries.

    • Voyager
      The Voyager is deployed in the Irish Sea. Pelagic trawlers are huge vessels built for deep sea fishing, with facilities for keeping the catch fresh over prolonged periods at sea. The hull is designed to ensure safety, and to give good fuel efficiency and high speed.


    • Quantus
      The Quantus is a modern trawler designed and built for efficient fishing. The vessel incorporates a number of innovative ideas, including a new hull form designed to combine optimum steaming and towing characteristics with fuel efficiency.


    • Arctia Offshore
      The turnkey project involved the fitting of combined Wärtsilä NOx Reducer (NOR) and Oxidation Catalysts (OXI) to the MSV Fennica and MSV Nordica.
