Executive Summary


Initially selected for engineering consulting by Petroleum Authority of Thailand (PTT), Fluor played a major role in Thailand's natural gas development project. We designed, engineered and managed construction of 360 miles of offshore and onshore pipeline.

The 34-inch diameter pipeline originated at the Union Oil Company of Thailand's offshore gas production in the Gulf of Thailand and extended 260 miles north. Onshore, the 28-inch diameter pipeline stretched 100 miles to the Bang Pakong and South Bangkok power plants. At the time of construction, it was the longest submarine pipeline in the world.

Client's Challenge


PTT is a fully integrated petroleum company with activities in exploration, production, logistics, transportation, refining, distribution and other petroleum related industries. The significant capital investment to develop Thailand's natural gas industry would reduce the country's dependence on foreign oil. It would also support and foster growth in Thailand's internal chemical and petrochemical industries.

Fluor's Solution


In the early study phase, we developed feasibility and optimization studies that established the master plan for the pipeline and onshore pipeline distribution systems.

Construction began with the establishment of a massive pipeline at Sattahip. Pipe laying for both the offshore and onshore lines began the following year. The offshore work was accomplished at an average rate of 1 ½ miles per day.

Conclusion


In subsequent projects, we continued to support PTT in its development and expansion of Thailand's energy processing and production infrastructure.
