Russian energy major Gazprom has confirmed a lengthy delay to its Sakhalin 3 offshore project, with first gas now unlikely before 2028, three years later than previously anticipated and one year after it is supposed to start supplying China through a new cross-border pipeline.
The revised schedule was disclosed by Sakhalin Governor Valery Limarenko during an industry gathering in Yuzhno-Sakhalinsk, where he noted that production at the complex would not begin until at least 2028.
Sakhalin 3 covers four separate deposits. The smallest, Kirinskoye, holds around 162bn cubic metres of reserves and began output in 2013 using subsea equipment supplied by FMC Technologies, now part of TechnipFMC.
Gazprom had initially intended to apply the same approach at South Kirinskoye, the largest field in the block with an estimated 815bn cubic metres of reserves.
That strategy collapsed in 2015 after the United States introduced sanctions following Russia’s annexation of Crimea. Since then, Gazprom has been forced to turn to domestic suppliers.
In 2019, it awarded a contract to defence manufacturer Almaz-Antey to design and build subsea production systems. While the company delivered two specialised subsea wellheads in 2023, progress on the remaining infrastructure has stalled, with no clear delivery schedule announced.
The continued delays underscore the difficulties Gazprom faces in developing technically complex offshore projects without Western technology, particularly as pressure mounts to secure new export flows to China.

UK's Serica Energy has revised its 2025 production guidance following maintenance challenges and scheduled subsea work on fields tied to the Triton FPSO.
The Triton Floating Production Storage and Offloading (FPSO) vessel is operated by South Korea's Dana Petroleum.
Serica Energy said production guidance has been reduced to between 29,000 and 32,000 barrels of oil equivalent per day (boepd), down from a previous range of 33,000–35,000 boepd.
Operator Dana Petroleum notified Serica of a temporary reduction in output from the Triton FPSO due to a vibration issue within the compression trains.
Production is currently running at a significantly reduced rate but is expected to return to normal levels by the end of September once repairs are completed.
Production net to Serica from the Triton FPSO exceeded 25,000 boepd in August. Once both compressors are operational, output will be boosted further, supported by additional production from the EV02 well on the Evelyn field.
