Weatherly History

Weatherly Inc. is an engineering design and construction company originally founded to perform consulting services as The D.M. Weatherly Company in 1954. The company was incorporated as a full service engineering operation in 1961. In January 1988, Nobel Industries Sweden purchased The D.M. Weatherly Company to become a subsidiary of its engineering operations division, Nobel Chematur. The new company was renamed Weatherly Inc. and was operated separately under direction of Nobel Chematur. The company was sold to Kellogg Brown & Root in 2016 and is organized in the Technology and Consulting Business group.

Weatherly entered the phosphate fertilizer industry in the late 1950s by commercializing the production of granulated diammonium phosphate (DAP) using the TVA rotary ammoniator/granulator process. Since that time, Weatherly has built approximately 30 granulation plants for phosphate, NPK, and urea fertilizers.

Weatherly then entered the nitrogen fertilizer industry in the early 1960s by developing a process for producing nitric acid. Weatherly's nitrogen fertilizer processes were further expanded in the mid-1960s with the introduction of technology developed in-house in the field of ammonium nitrate, urea and UAN solution.

Beginning in the late 1970s, Weatherly entered the international arena while continuing to serve its customers in North America. Through our association with KBR, Weatherly continues to expand and serve both its domestic and international customers.
