Fuel savings and long-term CII compliance
Hanwha and Accelleron have performed an engine part load optimisation (EPLO) for Höegh Autoliners supporting long-term energy efficiency for its 7,850 CEU (Car Equivalent Units) car carrier Höegh Detroit. The success of the project to improve the vessel’s Carbon Intensity Indicator (CII) rating has led to an order for EPLOs on a further seven vessels owned or operated by Höegh.
At a recent sea trial, EPLO demonstrated fuel saving of 10g/kWh, equivalent to 5% of total fuel consumption. The improvement not only enables the vessel to operate in a high CII rating but also provides substantial operating cost reduction in terms of fuel costs and EU ETS expenses and reduced CO2 emissions.
Working with engine builder Hanwha Engine Co, Accelleron optimised both engine tuning and turbocharger configuration, including the installation of components more suitable to the vessel’s lower speed profile. Turbocharger nozzle rings, turbine blades and compressor wheels were all adapted, alongside various engine parameters, optimising efficiency for a de-rated engine output of 79% of the original maximum continuous rating, tailor edged to the new propulsion upgrade. During the project, Höegh Detroit was also equipped with a new propeller that enables the vessel to reach same maximum speed as before the modifications, the only difference is the lower fuel consumption.
Sebjørn Dahl, Chief Operations Officer at Höegh Autoliners, said: “Operating with lower engine power is one of several energy efficiency measures being deployed by Höegh Autoliners as part of our commitment to being a leader in sustainable deep-sea shipping. The fuel efficiency impact of EPLO optimisation on Höegh Detroit exceeded our expectations, safeguarding the vessel’s long-term energy efficiency and market value. We are confident of similar success in future EPLO projects.”
“Sustainability and emission reduction is at the core of Höegh Autoliners’ strategy. This joint project with Accelleron and Hanwha shows very good results and is an example of decarbonisation in practice, said Sebjørn Dahl, COO, Höegh Autoliners.
