The new Ice Class Tug was christened by the wife of the President of Irving Shipbuilding, Inc., Karen Durrell, her husband Steve Durrell hosted the event. The tug, Stevns Icequeen had undergone sea trials and was accepted by the owner as meeting all of the specification requirements.

After delivery, the tug transited the Atlantic Ocean to Denmark to begin work for the owner. Upon arrival at its home port, Esbjerg, it was dispatched almost immediately to assist a Danish vessel in distress due to heavy weather that had lost steering power and evacuated most of the crew.

The Ice Class tugs will develop 60 tonnes of bollard pull while the non Ice Class tugs will develop 70 tonnes of bollard pull. A Kamewa bow thruster of 150kW is also fitted on all four tugs.
