ExxonNeftegas Sakhalin Island Onshore Processing Facility - EPC

Fluor was responsible for engineering, procurement, and construction management of an onshore processing facility (OPF) for Exxon Neftegas Limited in a remote area near Chayvo, Russia, close to the rugged Sea of Othotsk and neighboring Sakhalin Island.

This project feature some of the greatest challenges faced in design, logistics, and construction.

It illustrates Fluor's ability to work with the Client as well as with a multicultural workforce, global offices, and subcontractors in a challenging environment, delivering  dependability, expertise, and safety.

Onshore Processing Facility (OPF) -Sakhalin Island - engineering
Client's Challenge

As the operator of Sakhalin-1, Exxon Neftegas Limited (ENL) had to decide whether to use a typical stick-build construction approach or modular design and construction to meet a fast-track schedule. After a thorough review, ENL decided to proceed with a modular approach for a majority of the OPF and a stick-build approach for other portions of the facility. Fluor and its subcontractors agreed to take on the highly aggressive schedule.

The location of the project also presented a challenge. With Chayvo winter temperatures dropping to – 40 °F together with blizzard whiteout conditions, Fluor had to schedule module deliveries in the summer months of 2005 and 2006 to stay on schedule.

Fluor's Solution

To meet the fast-track schedule, Fluor engaged a sophisticated multi-office execution to perform the detailed design of 36 large ocean-going modules, each weighing up to 1,700 metric tons. Additionally, Fluor worked closely with a number of Russian design institutes on this project. Fluor analyzed the capabilities of several module fabricators around the world, selecting a South Korean company that could meet the delivery schedules.

Fluor used a single shared global-engineering PDMS model, allowing multiple offices to work around the clock. It was called “The Project that Never Slept,” as the complex design and construction process spanned numerous time zones around the world every day, from Moscow to Houston to the Chayvo construction site to Ulsan, South Korea to New Delhi, finally winding up back in Moscow.

A satellite-based communication system and execution platform used on the project was one of the most advanced systems ever designed. It linked all design participants with more than 20 construction contractors on Sakhalin Island.

Fluor, with an onsite workforce more than 80 percent Russian, continued to work through the winter, facing extreme environmental conditions. The site was prepared to receive the final 2006 sealift of modules, which arrived smoothly and were quickly set in place.

Conclusion

Fluor achieved mechanical completion of the onshore processing facility slightly ahead of the October 2006 due date.

As a result of Fluor's successful completion of the Chayvo Onshore Processing Facility (OPF) in 2006, the company was awarded a contract by Exxon Neftegas Limited in August 2009, on behalf of the Sakhalin-1 Consortium, to expand the OPF.
