Pon Power Scandinavia will supply engines for the new Siemens BLUEDRIVE PlusC™

A specially modified propulsion package to be used in a new offshore supply vessel for the Norwegian shipping company Østensjø Rederi.

Siemens and Østensjø approached Pon Power Scandinavia with an enquiry of supplying engines for the new and innovative propulsion system BLUEDRIVE PlusC™. The main objective for this project was a reduction in fuel consumption and operation of an SCR catalyst over the load range of 10-100 %. The goal is to have a significant reduction of environmental emissions, both NOx and CO2.

Along with the MaK factories in Germany we have modified two MaK 6M25C and two MaK 9M25C propulsion engines to function with the new Siemens floating frequency concept, developed specifically for this project for Østensjø Rederi.

From the outset it was very important to keep the fuel consumption on an average of around 200-210 g/kWh throughout an operation cycle for a PSV.

Another key objective was keeping a SCR application running at a load of 10-100% thereby giving NOx 0,5 g/kWh after the SCR implementation.

To keep load response also in the low rpm area it was necessary to develop an air assist system. This system will be further tested for this specific application to assure that the engines are operated at an ideal rpm-load curve.



The fuel consumption test results are very impressive as it is shown below. On average the fuel consumption is expected to be at least 15% below the fuel consumption of current systems for offshore vessels.



The vessel will be completed and in operation in autumn 2013.
