Greenland only six months of the year.

Between her launch and February 2015 she has put 7371 hours on her Cummins main without any problems. To meet the extensive electronic needs of mul- tiple winches, bow thruster as well as laboratories and navigational equipment the R/V Sanna has a pair of Cummins

QSM11D-powered generators to pro- vide 220 kW of power. Given her qual- ity build and strong service support by the Esbjerg branch of Granly Diesel A/S the research vessel can be expected to continue and an important asset to arc- tic ? sheries research for many years to come.
