Background• FMC Technologies have been working with Subsea Systems
in Russia for 6-7 years
• Main focus have been study work at different fields in the arctic area
• Late 2009 we were challenged by Gazprom Dobycha Shelf to develop a gas field in the Sakhalin area as a fast track subsea to beach development. Deliveries to take place summer 2011!
• An impressive decision making ability was demonstrated on the Russian side
• A start up contract was signed in April 2010, including long lead items.
• Signing of the final Hardware Contract (EPC) took place end June 2010.

Kirinskoye Subsea DevelopmentLocation
• 28km east of the Sakhalin Island in the Sea of Okhotsk
• Located within the Kirinsky Block
• Developed as part of Sakhalin III.
• Gas /gas condensate field discovered in 1992

Kirinskoye Subsea DevelopmentHydrate Prevention Strategy
• Cold temperatures and cooling effect of choking combined with produced water necessitate hydrate mitigation
• Chosen strategy is for continuous injection of MEG to inhibit produced water
• MEG injected at each Xmas Tree down stream of multiphase metering
• Remedial action by depressurizing
