Aiviq is an American icebreaking anchor handling tug supply vessel (AHTS) owned by Offshore Surface Vessels LLC, part of Edison Chouest Offshore (ECO). The $200 million vessel was built in 2012 by North American Shipbuilding Company in Larose, Louisiana and LaShip in Houma, Louisiana. She was initially chartered by Royal Dutch Shell to support oil exploration and drilling in the Chukchi Sea off Alaska where the primary task of the vessel was towing and laying anchors for drilling rigs, and oil spill response.[4][5][6]

The vessel has been called the world's most powerful privately owned icebreaker.[7]
