Establishing an optimal decarbonisation path for your fleet

With the entry into force of IMO’s energy efficiency regulations approaching, it is no surprise that compliance with Energy Efficiency Index for Existing Ships (EEXI) and Carbon Intensity Indicator (CII) are dominating discussions in shipping. For fleet owners, knowing when and how to adapt will become critical for maximising the value generation and useful life of their assets.

    Find the best way to adopt alternative fuels for your vessel fleet

    Are you thinking about adopting future fuels for your vessels but unsure how to start? Perhaps you need to know whether to convert your existing vessel to run on alternative fuels, or to invest in a newbuild.

    For an existing vessel, the study outlines the modifications needed to accommodate engines capable of combusting your future fuel of choice as well as the related fuel storage and auxiliary systems. The study includes preliminary engineering drawings for the layout of the key equipment needed and key piping diagrams as well as a written report providing valuable high-level information on the conversion.

    What does a feasibility study include?

    • Engine conversion plan
    • Recommended solutions for fuel storage onboard
    • Estimated structural modifications for the vessel
    • High-level weight change calculations
    • Automation and control system modifications
    • Operational comparisons of using alternative fuel vs diesel
    • A preliminary high-level cost estimate and project schedule
    • Risk assessment.
