During its service to the Oman oil and gas industry for over five decades, The Oman Construction Company (TOCO) has placed itself as a symbol of ‘Operational Excellence’ in its chosen areas of business. Since 1965, the company has been a trusted partner of major national and international oil and gas asset owners and operators in the Sultanate.

TOCO is part of Oman’s oil and gas legacy with several ‘Firsts’ to its credit. The list includes construction of the first pipeline, flow line, production station, tank farm, overhead power line. In 1967, TOCO moved the first rig at Fahud.


The Oman Construction Company L.L.C (TOCO) has been associated with Occidental of Oman Inc (OXY) since very early days of oil exploration and the relationship still continues. TOCO had created history way back in 1965 by constructing the very first oil facilities for PDO after commercial discovery of oil in Oman in 1962. TOCO then went on to add another page in the oil history of Oman by assisting Occidental to build their initial exploration and production facilities at Safah field.

Occidental found oil in 1983 at Safah in western Oman, close to the border with the United Arab Emirates. On 6th January 1991, New York Times reported the Safah oil discovery as “A Big Oil Find By Occidental”.

In 1984, OXY tasked TOCO to provide desert crew and equipment to support operation & maintenance of the facilities. The scope of work included:

  • Maintenance and enforcement of safety, environmental and work permit procedures
  • Fabrication and installation works
  • Maintenance of rotating equipment
  • Construction of steel and GRE pipelines, flow lines and piping
  • Electrical and instrumentation works
  • Facility maintenance
  • Transportation works


After a short break of two years, TOCO was once again awarded Safah field contract in April 2013.

The unique combination of unparalleled local knowledge, international expertise, excellent HSE track record, unmatched quality, ability to meet tough deadlines and ability to handle complex projects has maintained TOCO among the most sought after Oil & Gas service providers in the Sultanate of Oman.
