An unexpected operational “trip” at the Shetland Gas Plant led to notable gas flaring last Friday, as reported by TotalEnergies, the facility”s operator. The incident resulted in a “blowdown” that was audible in nearby areas, prompting concerns from local residents.
A representative from TotalEnergies explained that the blowdown was the result of an unintended emergency release of pressurized gas, typically caused by equipment malfunctions. This particular episode occurred during the testing of the plant”s safety systems.
“The trip and associated blowdown were unintended consequences of our safety testing,” the spokesperson stated. “Events of this nature remain well within the plant”s design operating limits, and there was no safety concern.” This incident contrasts with planned flaring events for which the public is informed in advance.
This blowdown follows the recent commencement of gas transport from the Shell-operated Victory field, located northwest of Shetland, to the gas plant. In compliance with regulatory reporting requirements, TotalEnergies has notified the Scottish Environment Protection Agency (SEPA) regarding the incident.
The Shetland Gas Plant, which began operations in 2016, processes gas from the Laggan and Tormore fields in the Greater Laggan Area (GLA) before distributing it via pipeline to the Scottish mainland.
Looking ahead, TotalEnergies is set to finalize the sale of its 40 percent stake in the Greater Laggan Area to Serica Energy by the first quarter of 2026. Originally, Total”s share was intended for sale to Prax, but that deal fell through following the administration of Prax Group”s parent company earlier in 2025. However, Serica has now agreed to purchase Prax Upstream for $25.6 million, which includes the rights to Total”s share in the Greater Laggan Area and the Lancaster field, previously wholly owned by Prax.
Other stakeholders in the Greater Laggan Area include Kistos, Ineos, and Viaro Energy, each holding a 20 percent share.
