Built in Norway. Scrapped in India. Reconditioned in Hamburg.

Life cycle of an Ulstein KRG engine. In service on a FPSO for 20 years. Now powering an offshore supply vessel.

It all begins in 1977. At a shipyard in France, two Ulstein KRG engines are fitted as power-generating units in the MV Monge. Under different owners and names, the vessel sees over 30 years of service.


The end comes in 2010. Scrapped. On the beach in Alang, the steel from the vessel is swallowed by an Indian furnace. But not the Bergen KRGs.


Chance has it that the engines are offered for sale to Gold Engineering in Hamburg, which is familiar with them from earlier maintenance work.


Chance has it that at the same time on the other side of the world, serious damage is discovered in one of the main engines of a Canadian ocean-going supply vessel during overhaul work. Suitable cylinder covers have to be found urgently, or the vessel’s current charter contracts will fall through.


Luckily, the used K-series engines have already been dismantled by Gold Engineering and the key components are already being reconditioned, including the cylinder covers that are so urgently needed.


Following classification tests by Germanischer Lloyd, 1,500kg of components are put on the next plane to Canada. And so begins a second life for the 30-year-old components.


Ulstein Bergen K-series

Introduced in 1970, the K-series was designed mainly to be a genset drive, but they have been used for main propulsion in tugs, offshore supply ships, and fishing vessels.
