  • How to minimise SOx the Alternatives

    CHANGE TO MGO Run full time on Marine Gas

    Oil (MGO).

    Convenient No change over ...but expensive


    CONVERT TO LNG Convert engines to run on

    gas (LNG).

    A solution which also reduces NOx and particulates ...Wrtsil believes

    strongly in marine gas markets

    USE SCRUBBERS Install an exhaust gas

    cleaning system (scrubber).

    Works with high % S fuel. ....works in combination with SCR.....lowest total lifecycle cost

    Key factors to start Bit Viking LNG Conversion project

    Why LNG Conversion?

    - Tarbit shipping together with Statoil want to have one of the safest and most enviromental friendly chemical tankers in the world

    - To fulfil new IMOs 2015 regulations concerning SOx emissions - Funding from the NOx Fund - Gas is the future for shipping
