Zamil O&M was founded in 1977 by Al Zamil family of Saudi Arabia. It was registered as a limited liability company with the Ministry of Commerce, Dammam under Commercial Registration No. 2051003290.
With the creation of Zamil O&M’s sister company, Zamil Offshore Services Company (ZOSCO), in March 2008, Commercial Registration No. 2051003290 was absorbed by ZOSCO. Thus, Zamil O&M obtained a new Commercial Registration No. 2051037917 in 2008 from the Ministry of Commerce.
