How to minimise SOx – the Alternatives

CHANGE TO MGO Run full time on Marine Gas

Oil (MGO).

Convenient No change over ...but expensive

fuel

CONVERT TO LNG Convert engines to run on

gas (LNG).

A solution which also reduces NOx and particulates ...Wärtsilä 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 IMO’s 2015 regulations concerning SOx emissions - Funding from the NOx Fund - Gas is the future for shipping
