Wärtsilä Vasa 32 Performance upgrade

An ageing VTR turbocharger can affect engine performance, increase specific fuel oil consumption (SFOC) and limit the maximum power output. The Wärtsilä Performance Upgrade for Vasa 32 engines is a comprehensive, tailored package that boost engine performance, reduces operating cost and increases operational flexibility - all while helping you to comply with increasingly strict emission requirements.

The upgrade is suitable for all Wärtsilä Vasa 6R32 and 12V32, as well as most 16V32 and 18V32 that mainly operate between 50% and 100% load and is particularly recommended for installations operating in extreme environmental conditions. In addition, most of the Vasa engines manufactured after 1991 may also be performance upgraded following a Low NOx conversion.

The upgrade process involves replacing the VTR turbocharger with a modern, state-of-the-art, high-efficiency turbocharger, enabling the use of earlier inlet valve closing, known as the Miller concept. The upgrade reduces SFOC by up to 5 g/kWh, according to laboratory tests performed with an engine running at 85% load. Depending on the initial engine configuration, a combination of NOx Tier I or II and SFOC benefit level can be chosen.

Key benefits

  • Enable fuel savings up to 5 g/kWh
  • Maintain or increase NOx compliance to Tier I or II
  • Reduce maintenance costs
  • Increase operational flexibility

    Technical info

    The upgrade is a package solution that includes all the necessary parts. The need for engine tuning will be determined on a case-by-case basis. 
    Delivery includes:

    • New turbocharger for increased efficiency
    • New camshaft for advanced Miller inlet valve timing
    • Re-designed cylinder liners, pistons and connecting rods for older engines
    • Engine tuning
    • SOLAS insulation for the turbocharger
    • Automation components
    • Components needed to install the new turbocharger on the engine
    • Installation and commissioning

    The upgrade is particularly recommended for installations operating in extreme conditions where high environmental temperatures limit the engine’s maximum continuous rating.

    Benefits

    • Enable fuel savings up to 5 g/kWh
    • Reduce maintenance costs
    • Enable a reduction in NOx emissions in line with IMO Tier I and II limits
    • Increase operational flexibility
    • Increase turbocharger speed margin by 10%
    • Payback period as short as two years

    Application

    The upgrade is suitable for all Wärtsilä Vasa 6R32 and 12V32, as well as for most 16V32 and 18V32 installations that mainly operate between 50% and 100% load.
