Interview with Commissioning Engineer Per Lunde

My name is Per Lunde. I have been working at MAN for 27 years, mainly in service departments and for the last 8 years in test department. The first 5 years, I was working as Field Test Engineer and presently I am working as Manager for High Speed Field Tests.

Being the closest to the engine testing, what is the most exciting aspect of your work?

Here, I have clearly three aspects in mind. At first, the process in having the engine ready for the pilot phase is very exciting. The next step is the installation on board. Of course, experiencing installations of new engine types feels very special every time. Furthermore, following the engines in their performance and seeing the inspections, if we have reached our targets or if we can do improvements, is also a very crucial aspect, which determines a lot for the next steps in engine development.

Looking back, what was your most impressive experience within the MAN 175D project?

I believe the most impressive experience, I had in the 175D project, was the process of handling the retrofit of the offshore vessel “Edda Fonn”. This included a very close and very good cooperation with our customer Østensjø Rederi. Østensjø wanted to exchange an existing genset on board with the MAN 175D and provided a spare alternator, which should be used for testing on the testbed. Furthermore, integrating new propulsion equipment into an existing on-board environment is a challenging task, but due to the modularity also of the electronics things could be fast and professionally handled. And not to forget the shipyard in Frederikshavn, which was the partner who took care of the rebuild onboard.

How did
Østensjø Rederi become a pilot customer for the MAN 175D?

We wanted to find a retrofit opportunity in order to quickly collect running hours. Østensjø Rederi is known for its innovation in the marine offshore sector. Therefore, using the most modern propulsion machinery and thus using a MAN 175D genset was a perfect match both for Østensjø and MAN. Finally, after a few phone calls and meetings all details regarding the set-up were agreed.

How is the feedback from Østensjø Rederi so far?

The crew is highly satisfied and the service inspections during 7.000 running hours were excellent – so all is good.

As a further first marine pilot application, a catamaran ferry was chosen. How was the experience during installation onboard of the “Oceanna 175” and its first fire?

Well, for the installation onboard of the catamaran ferry, we had to be smart, as we introduced the MAN 175D into an application, which had challenging requirements on tight and limited engine room installation space. But with the cooperation of the PT Palindo shipyard and with assistance from our local MAN Diesel & Turbo office in Singapore and, once again, good team work in all groups of the MAN 175D project we could prove that the MAN 175D fits also perfectly into very narrow engine rooms.

With our Alphatronic remote control system we could then quickly launch the ship and sail on full speed, as engine and propulsion control were already integrated systems. Finally, the MAN 175D high speed engines were performing as expected and the owner has been very satisfied with performance, vibration level, noise level and fuel consumption.


Thank you, Per, for your insights!
