9th Russian-Norwegian Oil & Gas Conference
Subsea Development of the Kirinskoye Field
Presented by: Endre Smedsrud, FMC Technologies
St Petersburg, 27th January 2011
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 DevelopmentWell Location
Kirinskoye Subsea DevelopmentXmas Tree
• Enhanced Horizontal Xmas Tree (EHXT) System
• 5-1/8” Production x 2-1.16” Annulus bores
• Tubing Hanger located within XT body
• Connects to a UWD-15 wellhead
• Separately retrievable modules:– Choke Module (CM)
– Subsea Control Module (SCM)
Choke Module
Contains instrumentation in a retrievable module:
• 5” Production Choke Valve
• 2” MEG Flowloop
• Multi Phase Flow Meter
• MEG Dosing Throttle Valve
• Acoustic Sand Detector
• Erosion Probe
• Dimensions: 1,4 x 2,8 x 2,6 m
Kirinskoye Subsea DevelopmentSubsea Control Module
Kirinskoye Subsea DevelopmentSubsea Control System
• Electro-hydraulic closed control system
• Flow metering system• Provides live feedback of well data• Controlled by operator from Master
Control Station (MCS)• Connects to subsea equipment via
dedicated control Umbilical• XT mounted Subsea Control
Module• 2 x SCM on manifold• ESD and PSD link to onshore plant
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
