Yadana pipeline

In January 1997, the Tasco Mannesmann Joint Venture (TMJV a Thai-German Company Joint Venture),[3] won the pipeline contract which included the procurement, construction and commissioning of the pipeline and related facilities, as well as the design of the Supervisory Control and Data Acquisition (SCADA) and Telecommunications system including a Fiber optic cable system.

With issuing the Tender documents for Bidding to Contractors the engineering was not finished and it was completed only during the execution phase of the project incorporating all the changes ordered by PTT.

Furthermore, as PTT's Engineer and Consultant Nova Gas/OGP was responsible for the entire construction supervision of the Yadana Gas Pipeline Project.

The pipeline has a diameter of 42 inches and is around 240 kilometers long and it has a total number of 12 Block Valve Stations that includes 6 Scraper Facilities, an operations and maintenance center including a gas meter station and a SCADA Telecommunications system that was connected to the Petroleum Authority of Thailand's (PTT) existing SCADA system.

According to PTT the Yadana Gas Pipeline is a highly sophisticated technical system[13] and complies to the Thailand Quality Award (TQA) criterion.
