M.W. Kellogg Ltd. (MWKL) was a British full service contractor primarily serving the hydrocarbon market. It had the capability to execute large international projects from conceptual feasibility studies through fixed price turnkey mega-projects.
Established in the 1930s, it was a wholly owned subsidiary of the M.W. Kellogg Co. It was a private limited company jointly owned by KBR and JGC Corp. Formal joint ownership between KBR and JGC was established in 1992, when JGC purchased 45 percent of MWKL stock—although a strong relationship between the two companies existed for much longer. It is now wholly owned by KBR after a takeover that occurred December 2010 – January 2011. M.W.Kellogg Ltd. has now changed its name to KBR UK Ltd.
