Moreover, total fuel consumption of a potential alternative is calculated simply using energy conversion factors in comparison to a conventional fuel. However, each compliance-option comprises of unique process-components which demand diverse operational, electrical and heating energy requirements which in turn alter their fuel consumptions and emission inventories. Therefore, each compliance-pathway should be assessed individually using in-situ data in order to estimate fuel consumptions and emission inventories rather than using energy conversion factors between them.
A case study which utilizes in-situ data is conducted to assess the effect of fuel-specific processes on energy/operational demand and the emission estimates between residual heavy fuel-oils and liquefied natural-gas for a bulk carrier. The findings reveal that allocation and apportion of fuel-specific electrical/heating energy demands as well as operational components to each compliance option would produce more accurate emission estimates as well as realistic cost comparisons. Moreover, the study endorses that the use of natural gas as a marine fuel is highly commendable and asserts that in fact more emission reductions can be achieved than previously estimated.
