Trinidad and Tobago LNG exporter Atlantic sees 2017 as the worst year yet of a prolonged natural gas deficit, and is raising concerns about the risk of operating with diminishing supply.
The 14.8mn t/yr Atlantic liquefaction complex in Point Fortin "has suffered on average an over 30pc gas supply shortage and there is no significant improvement in the foreseeable future," chief executive Nigel Darlow says. "In fact, 2017 is predicted to be worse still with an overall gas shortage close to 35pc."
The shortage "is very serious for us, equating to something like 75 LNG cargoes lost each year," Darlow said. "Atlantic is suffering the vast majority of the gas supply shortage in the country."
The supply gap poses operational risks, he said, adding that the current combination of
low gas supply and low global commodity prices present "challenges to how the company manages safety."
The company faces "daily challenges in continually turning turbines and compressors up and down and on and off," he said. "That's not how they were designed. We must ensure that the low levels of plant utilization do not present process safety risks which are not fully understood and properly managed."
The four-train Atlantic complex is owned by BP, Shell, China's sovereign wealth fund CHIC unit Summer Soca and Trinidad's state-run gas company NGC. But different shareholding structures in each train complicates the allocation of feedstock restrictions.
The deficit in local gas supply depressed LNG production by 17.7pc to 18.2mn m³ in January-September compared with the corresponding period of 2016, the energy ministry reported.
Gas production fell by 13.8pc to 3.338bn ft³/d (93.5mn m³/d) in the nine-month period.
LNG production consumed 1.662bn ft³/d of Trinidad´s gas in January-September, 13.8pc less than a year earlier.
The gas shortage is the result of limited upstream investment, NGC has said.
South American markets currently account for 62pc of Trinidad´s LNG exports, with 12pc going to Europe, 6pc to the Middle East and 4pc to Asia-Pacific, according to the energy ministry.
Trinidad hopes to ease the curtailments by purchasing gas from Venezuela's offshore Dragon field, and has a tentative agreement with Caracas to establish a commercial venture to exploit gas deposits that straddle their maritime border.
Increased gas will be delivered in 2017 from projects operated by BP, BHP Billiton and EOG Resources, the companies and the energy ministry say.
