Norsk Hydro is one of the largest aluminium companies worldwide. Norsk Hydro had a significant presence in the oil and gas industry until October 2007, when these operations were merged with Statoil to form what is now called Equinor. Norsk Hydro started off as a fertilizer producer and agricultural products: its agricultural division was in 2004 demerged into the independent company Yara International.
Norsk Hydro was represented by Knut Wiig MATHISEN both in Global CAPE-OPEN and in CO-LaN. Knut Wiig MATHISEN led the UNIT Special Interest Group from its inception at the beginning of 2002 till mid-2003 when Norsk Hydro resigned from CO-LaN.
CO-LaN has kept in touch over the recent years with Yara International: as employee now of Yara International Knut Wiig MATHISEN attended the CAPE-OPEN 2012 Annual Meeting while Volker SIEPMANN attended the CAPE-OPEN 2016 Annual Meeting and the CAPE-OPEN 2020 Annual Meeting.
