MAN 175D Genset collects over 6,500 hours on offshore vessel

After more than 10,000 running hours on the testbeds and a successful DNV/GL type approval, an MAN 12V175D MEL genset including SCR equipment to fulfill IMO Tier III emission regulations has been installed on board of the platform supply vessel (PSV) “Edda Fonn” since 2016.

The vessel "Edda Fonn" from Østensjø Rederi is an advanced, cost effective, flexible 90 meter vessel used for inspection, maintenance, survey and light construction service. The vessel is equipped with a DP2 system and is designed for the most challenging sea applications. The retrofit into an offshore service & supply application with its challenging load profile – low engine load during dynamic positioning during working mode and high engine load during transit – was selected in order to ideally demonstrate:

     1. the easy and fast installation and commissioning of the MAN 175D Engine and Genset
         into already existing rooms, and
     2. its efficient operation and reliability.

An existing genset onboard was exchanged with the MAN 12V175D-MEL genset, rated at 1,920kW, at 60Hz. The MAN 175D genset is engineered with all auxiliary components attached on the base frame, whilst fitting into the existing vessel foundation.

Since the end of 2016, the MAN 12V175D MEL genset has collected over 6,500 running hours. Chief engineer onboard, Mr. Nils Are Hermansen, says “The genset is running smoothly for a few thousand running hours now. It’s more efficient than our former propulsion set-up both in terms of fuel consumption and maintenance efforts and costs. Due to the compactness of the genset and its small footprint, we could within a week and without any major modifications install it into the existing vessel system.”
