The company took the whole facility offline for annual maintenance in July, the 1st time both production trains entered maintenance simultaneously
Yuzhno-Sakhalinsk, August 18 - Neftegaz.RU.
The Amur River LNG carrier has departed from the Port of Prigorodnoye with the 1st LNG
cargo loaded after the Sakhalin-2
integrated gas system major turnaround campaign.
LNG train 1 has been restarted, while post-shutdown commissioning continues at train 2.
Alexander Singurov, Deputy Production Director, said:
- Some activities were completed for the 1st time, not only in Sakhalin-2 project’s history, but also in Russia
Once of such unique technical challenges was the replacement of 2 out of the 4 LNG loading arms at the LNG jetty
This complex operation was carried out using Pijlgracht, a specialised vessel equipped with 2 main cranes with a lifting capacity up to 700 metric tonnes each
At the production complex, we also modified the mixed refrigerant compressor and the emergency shutdown system
According to Evgeny Udovenko, Head of Engineering and Maintenance, the 2021 major turnaround campaign was preceded by a lot of preparations and case reviews that took into account COVID-19
-related risks and international vendors’ personnel travel restrictions.
Overall, 3,000 company and contractor team members completed approximately 1,600 work orders and accumulated over 1.2 million man-hours without a single lost time incident.
- Moreover, in view of the scale and duration of our summer turnaround campaign, the company decided to complete some of the scope originally scheduled for autumn and winter 2021 and for 2022 during this TA
He also mentioned that, thanks to the scheduled and extra maintenance performed this year based on equipment inspections and diagnostics, the company
intends to skip a major turnaround next year.
This will allow Sakhalin
Energy to reduce OPEX, do activity planning more efficiently and effectively, and transition the entire integrated gas chain to a four-year maintenance cycle going forward.
With this approach, each train will be shut down once every 2 years.
