Hanwha, Acceleron conduct engine optimization on Höegh Autoliners’ ship

South Korean engine manufacturer Hanwha Engine and Swiss turbocharger producer Acceleron have performed an engine part load optimization (EPLO) for Höegh Autoliners’ 7,850 CEU car carrier Höegh Detroit.

Working with engine builder Hanwha Engine, Accelleron optimized 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.

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.

According to the partners, 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, Acceleron noted.

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.

“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 optimization 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,” Sebjørn Dahl, Chief Operations Officer at Höegh Autoliners, said.

“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 decarbonization in practice.”

Accelleron has received orders for more than 20 EPLOs to date, many for multiple sister vessels.

“Accelleron’s EPLO upgrade solution delivers peace of mind for shipowners dealing with complex decarbonization demands, a simple and effective measure contributing to compliance with greenhouse gas regulation while benefitting from substantially reduced fuel costs,” Accelleron, Product Manager Upgrades, Matthias Reichmann, said.

Earlier on, Acceleron signed a strategic cooperation agreement with China Classification Society (CCS) to work on the development of green fuels and upgrade of ammonia and methanol engines for ships.
