NORSK HYDRO ASA.

H110 is blue with a white Viking ship at the upper hoist; H111 places it more centrally. A company photograph dated 15 March 2002 shows the H111 design on flags Rosanoski considers not intended for sea use.

Mitchell shows N504 in addition to H112 under a different name, noting Hydroship as an associate. N505 appears to represent Nordslandfjord, listed under Hydroship in Lloyds 1978–79.

Norsk Hydro-elektrisk Kvælstofaktieselskab was founded on 2 December 1905 to use Norwegian hydroelectric power in mineral-fertiliser production. It became Norsk Hydro ASA in 1971 and adopted Hydro as its general short name in 1993. Hydro Agri sold its ship agencies to Barwill in 2002 and was demerged as Yara International in March 2004. The Norwegian Government held 41% in the cited 2003–05 registers. Hydro subsequently combined its petroleum business with Statoil in 2007 and concentrated on aluminium.
