3 Designed for maximum flexibility and reliability, FMC s F Series Subsea Chokes and Flow Modules are ideal for production, injection, gas lift and waterflood applications. Best practice features leverage FMC s field proven subsea experience and technology, including metal and elastomeric seals, mechanical clamp technology, fluid dynamics, flow assurance and system design. FMC s subsea choke family includes the Non-Retrievable Choke, Insert Retrievable Choke, Insert Running Tool, Hydraulic Stepping Actuator and Electric Actuators. Additionally, FMC has introduced Retrievable Flow Modules, allowing modular packaging of chokes, flow meters, pressure/temperature sensors and erosion detectors in an easily retrievable/re-deployable and/or upgradeable package. bility 3

4 Testing Rigorous Qualification Testing API 6A/17D (ISO / ISO ) PR2, Annex F tested Extended FMC endurance tested at 300 F Independent Cv tested to ISA Independent erosion test Independent API 6A Annex I slurry test Hyperbaric tested to 10,000 feet (3,048 m) water depth Endurance tested at 1 million pulses/steps Subsea field-tested under severe operating conditions 4

5 Non-Retrievable Subsea Choke Features a multi-hole tungsten carbide plug and cage design with a steel protective jacket around the cage to prevent impact damage. The plug is fully guided, pressure balanced and rigidly attached to the stem to eliminate flow induced vibration. Large gallery to mitigate erosion and extend choke life Fully supported cage is capable of reverse flow at maximum working pressure Body outlet designed to accept a full tungsten carbide liner for complete wear protection Non-Retrievable Subsea Choke Hydraulic Stepping Actuator Designed as a fail as is with a Class IV ROV manual override, the FMC Hydraulic Stepping Actuator provides remote position feedback via a direct stem mounted LVDT. Two double acting spring return pistons Crossover tubing to guarantee operation in all hydraulic back pressure conditions No net actuator housing volume change during the stepping mode Large top mounted visual indicator Compensation via an enclosed diaphragm Hydraulic Stepping Actuator 5

6 Proven exp Insert Retrievable Subsea Choke Features an FMC field proven KL two piece hinged clamp connector with a horizontal Class IV ROV interface. Funnel type guide structure to interface with choke running tool Funnel equipped with ROV grab bar and electrical parking receptacle Choke body with twin stab wet-mate hydraulic connectors Hot stab test port between primary and secondary body to insert seals Multi-hole tungsten carbide plug and cage insert with steel protective jacket to prevent debris impact damage Insert Retrievable Subsea Choke Retrievable Flow Module 6

7 erience Subsea Choke Running Tool The FMC subsea choke insert running tool is wire line deployed with ROV assistance for insert retrieval and deployment. Three passive pistons provide soft landing Latching and unlatching the tool is purely a mechanical function Tool completely extends to protect the choke insert on retrieval and deployment Running tool provides a 45 rough alignment capture angle Hydraulic hot stab provided to assist in choke insert removal Subsea Choke with Insert Running/Retrieval Tool Retrievable Choke and Flow Module The FMC Retrievable Choke Module provides easy retrieval and deployment on a down line with ROV assistance; no running tool is required. Improved reliability and availability due to simplified interfaces Small compact footprint allowing straightforward subsea retrieval and deployment Increased visibility for guidance and connection Choke insert and body are recovered as an assembly, ideal for high erosion service Utilizes a cost effective bolted bonnet design Improved thermal performance due to simplified interfaces and ease of adding insulation onto entire choke body and actuator Upgradeable by adding retrievable flow meters and sensors Reconfiguration is contained in the flow module permitting standardization of core tree components Sensitive components can be retrieved and deployed without performing major workovers Allows for easy conversion from production tree to water injection service and vice versa 7
