Atyrau, Kazakhstan – September 19, 2023 – Tengizchevroil LLP (TCO) has successfully completed one of the most complex turnarounds in its history ahead of schedule. Production at all TCO’s units at Tengiz has safely resumed.
For three years, TCO has meticulously planned the Complex Technology Line-2 (KTL-2) turnaround, which involved over 5200 Kazakhstani professionals at its peak. The turnaround activities are aimed at ensuring the reliability and safety of the Tengiz KTL-2 equipment and have included the implementation of additional environmental protection projects.
“I would like to express my appreciation for the strong partnership between TCO and its contractor business partners, as well as the dedication of TCO team, in managing this turnaround and reaching this significant milestone. I would also like to recognize the support we received from the Republic of Kazakhstan’s authorities,” said Kevin Lyon, TCO General Director.
For the first time in TCO’s history, its team successfully replaced an approximately 100-ton, 37-meter-tall vessel, with a new, metallurgically upgraded column as well as replaced three sweet gas mole sieve dryers, all of which were fabricated in Kazakhstan by local companies.
“TCO is committed to the continued development of Kazakhstani manufacturers and service providers in order to create significant benefits for Kazakhstan,” said Konilkosh Suyessinov, TCO Deputy General Director.
The turnaround work was conducted in accordance with Republic of Kazakhstan (RoK) legislation and in alignment with international oil and gas standards.
