Last year, Bechtel released a report on an incident at the Port Arthur LNG construction site in Texas.
Bechtel has identified seven factors that together contributed to the incident, which resulted in three fatalities and two injuries.
In March 2023, Sempra Infrastructure, in which Sempra is reducing its ownership to 25 percent, took a final investment decision on the first phase of its Port Arthur LNG export project worth about $13 billion.
Bechtel won the $10.5 billion EPC contract, which includes building two trains with a total capacity of about 13 mtpa and two storage tanks with a capacity of 160,000 cbm.
The expected commercial operation dates for train 1 and train 2 are 2027 and 2028, respectively.
In addition, Sempra Infrastructure took FID on the second phase of the Port Arthur LNG project last year.
Including the first 13 mtpa phase, the facility will have a total capacity of about 26 mtpa.
The expected commercial operation dates for Train 3 and Train 4 are 2030 and 2031, respectively.
