Project to cut fuel consumption by up to 10%


Joint initiative aims to merge existing technologies to reduce fuel consumption and emissions.

MAN Diesel & Turbo has revealed that it recently signed a cooperation agreement with Swedish energy and environmental technology company Opcon to exploit the possibilities arising from the merging of Opcon's ‘Powerbox' WHR technology with MAN Diesel & Turbo's diesel engines in order to cut fuel consumption and reducing emissions.

The companies will examine how best to exploit the possibilities offered by re-using waste-heat energy from low-temperature heat sources utilising the Opcon Powerbox technology.

The first reference - a marine installation that utilises waste heat for electricity production - is currently underway with the Opcon Powerbox integrated with a two-stroke MAN B&W 8S60ME-C8 engine aboard a newbuilding owned by Wallenius, the Swedish shipping group.

The Opcon Powerbox can be integrated with smaller engines in contrast with existing WHR units that are targeted at higher-temperature applications and larger engines.

It is said to directly influence the performance of ships by reducing the amount of fossil fuels they consume during operation by 5-10 percent. As a result, MAN Diesel says the technology also cuts carbon, NOx and sulphur emissions.
