Knutsen NYK Offshore Tankers (KNOT) is the second largest shuttle tanker operator in the world. KNOT is a joint venture between Norwegian-based Knutsen OAS Shipping and Japanese-based Nippon Yusen Kabushiki Kaisha (NYK), and was set up in 2010 following NYK's acquisition of 50 per cent of the shuttle tanker fleet from Knutsen OAS Shipping. Today KNOT has a fleet of 25 advanced shuttle tankers, 3 new buildings, and one Floating Storage and Offloading Unit (FSO).
