Wärtsilä Oil-to-Water Conversion Services
Revolutionising the industry

Made for the modern world

From environmental compliance to risk reduction, a sea water lubricated system can bring significant benefits to ship owners and operators.

Experienced in oil-to-water conversions, we can manage the entire conversion process and supply Original Equipment Manufacturer (OEM) spare parts. 
Looking after our environment.

    Converting to a sea water lubricated system can offer significant benefits to ship operators and owners by:

    • eliminating of accidental oil pollution risk and associated fines relating to green ship certification;
    • reducing the risk of a vessel being impounded as a result of accidental stern tube oil loss;
    • providing an environmentally sound solution;
    • ensuring compliance with Marpol Annex 1;
    • removing the likelihood of shaft seal damage following cable or rope entanglement; and
    • simplifying the mechanical makeup. 

    We can oversee the entire oil-to-water conversion process by:

    • removing seals, bearings, pipe work and tanks from the vessel;
    • shrink fitting journals to the shaft;
    • applying a corrosion-preventative coat; 
    • installing water lubricated composite bearings and an inboard water lubricated seal; and
    • preparing a proposal and assisting with long-term cost analysis.
