Wärtsilä Vasa 32LN 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 32LN engines is a comprehensive, tailored package that boosts engine performance, reduces operating costs and increases operational flexibility – all while helping you to comply with increasingly strict emission requirements.

The upgrade is suitable for all Wärtsilä Vasa 6R32LN and 12V32LN installations that mainly operate between 50% and 100% load and is particularly recommended for installations operating in extreme environmental conditions. In addition, Vasa 32 engines manufactured after 1991 may also be upgraded following a Low NOx conversion. The 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. 

    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
    • New camshaft for advanced Miller inlet valve timing
    • 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 of 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 6R32LN and 12V32LN installations that mainly operate between 50% and 100% load.
