Changing tankers to inexperienced fuels is possible, MMMCZCS says

Changing tankers to inexperienced fuels is technically and economically possible with cautious fleet transition planning and consideration of asset age, a brand new report discovered.

The report, launched by the Mærsk Mc-Kinney Møller Middle for Zero Carbon Delivery (MMMCZCS), outlines the mission outcomes associated to changing tankers to methanol or ammonia fuels.

Transitioning the world fleet to climate-friendly different fuels is seen important for the decarbonization of the delivery business. Nonetheless, vessels being constructed or ordered at present will probably be working for many years to return, and many different fuels aren’t but out there at scale.

Subsequently, shipowners face a problem in selecting which different gasoline and applied sciences they need to construct their decarbonization methods round, in addition to most successfully time their investments in these options. For instance, is it higher to construct a vessel that is able to function instantly on different fuels akin to methanol or ammonia, or a vessel that may be transformed to operation on these fuels at a later date – and, if the latter, how a lot ought to be invested in preparation for the choice gasoline on the newbuilding stage versus in later retrofitting?

MMMCZCS has analyzed the technical, financial, and environmental impacts of getting ready vessels for conversion to different fuels.

The report thought-about reference designs for 2 forms of tankers: LR2 and VLCC. As defined, these vessel varieties are two of the biggest within the tanker section, usually journey lengthy routes, and have a excessive gasoline consumption ― due to this fact, they’ll present a superb illustration of the financial and environmental impacts of various selections regarding vessel conversion.

One primary takeaway is that the business possesses the required know-how and engineering experience for these conversions.

On the subject of the financial influence, the variations in CapEx differ relying on the specified inexperienced gasoline and vessel vary chosen. Typically, essentially the most cost-effective possibility is tanker conversion from gasoline oil to methanol, adopted by conversion to ammonia.

MMMCZCS highlighted that conversion to different fuels impacts a vessel’s working envelope, because of the vitality density of the choice fuels and their corresponding gasoline tank measurement necessities. To maintain the identical operational vary as on fossil fuels, shipowners should contemplate both including tanks on deck (with a ensuing influence on dwt) or giving over a part of the cargo capability to gasoline tanks.

“As a part of this mission, we now have centered on choices that cut back the vessel’s working vary however protect its cargo capability. Primarily based on business data, we consider that such options have business applicability,” the middle stated.

“Our evaluation right here exhibits that even conversions after ten years of operation on fossil fuels can nonetheless yield appreciable environmental influence. Nonetheless, one should additionally contemplate the monetary viability of creating such a CapEx funding at this level within the vessel’s lifetime,” MMMCZCS concluded.
