In 2015, data of the Nordic Erika, a general cargo vessel trading in the North- and Baltic Sea, was analysed. The owner planned a conversion from HFO to MGO as fuel, following the SECA requirements. As the fuel bill would double, saving fuel was crucial. After analysing 8 different retrofit options, the best option proved to be a different combinator curve.
Sailing the vessel with the combinatory drive clearly resulted in a large saving reaching up to 20%, whilst the same speed was maintained. It means up to 2 tons per day less fuel, and at lower sailing speeds the savings become even larger. A significant saving like this is not only welcome, it is revolutionary!
