For the third time this year, a Paris-based firm has won a major engineering and design contract with a Lake Charles petrochemical company.

Sasol’s GTL complex is expected to produce more than 96,000 barrels of diesel fuels and chemicals each day.

Sasol officials announced Monday that Technip has been awarded the front-end engineering design contract for the company’s gas-to-liquids complex. Sasol expects to conclude that phase and reach final investment decision for the GTL project in 2016.

The estimated project cost is between $11 billion and $14 billion.

Last month, Sasol awarded Technip a contract to supply proprietary ethylene technology for its proposed ethane cracker facility.

In July, Flour Corp., an engineering firm based in Irving, Texas, was awarded Sasol’s main contract for the ethane cracker project.

Technip was also awarded a contract in August for Trunkline LNG’s proposed expansion in Lake Charles.
