[3] The primary mission of the vessel is to provide supplies of fuel, ordinance and equipment for warships that are part of the Norwegian Task Group (NorTG) to expand the force's operational endurance at sea.

[3] Because of the delays during construction of HNoMS Maud, two Reine-class patrol vessels of the Norwegian Coast Guard, Olav Tryggvason and Magnus Lagabøte, were transferred to the navy as auxiliary ships.

According to the Navy and the Ministry of Defence, all problems with the ship were to be tackled during its test run, with the goal of having the vessel in operation during the second quarter of 2020.

[12] In September 2020 Maud was declared safe and she sailed to Nieuwe Haven Naval Base of the Royal Netherlands Navy in Den Helder for work needed on her replenishment at sea masts.

[16][17] In September 2021 the ship started her maiden deployment, joining Standing NATO Maritime Group 1 as a "fleet oiler".

[18][19] Later that month, she performed her first replenishment at sea operation with an allied vessel, the Dutch frigate HNLMS Van Amstel.
