Chokes and Flow Modules

FMC Technologies' F series Subsea Chokes and Flow Modules are suitable for production, injection, gas lift and waterflood applications. They are designed for maximum reliability and include "Best Practice" features that leverage FMC Technologies' field-proven subsea experience and technology, including: metal and elastomeric seals, mechanical clamp technology, fluid dynamics and flow assurance.

Systems & Products

Subsea Choke Running Tool
The tool is wireline deployed with ROV assistance for insert retrieval and deployment.

Features and Benefits:
  • Three passive pistons provide soft landing
  • Latching and unlatching the tool is purely mechanical
  • Tool completely extends to protect the choke insert on retrieval and deployment
  • Running tool provides a 45 degree rough alignment capture angle
  • Hydraulic hot stab provided to assist in choke insert removal
Insert Retrievable Choke
Features a FMC Technologiesfield proven "KL" two piece hinged clamp connector with a horizontal Class IV ROV interface.

Features and Benefits:
  • Funnel type guide structure to interface with choke running tool with ROV grab bar and electrical parking receptacle
  • Choke body with two stab type 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
Non-Retrievalbe Subsea Choke
Features a multi-hole tungsten carbide plug and cage design with a steel protective jacket to prevent impact damage.

The plug is fully guided, pressure balanced and rigidly attached to the stem to eliminate flow induced vibration.

Features and Benefits:
  • Large gallery to mitigate erosion and extend choke life
  • Fully supported cage is capable of reverse flow at maximum working pressure
  • Body outlet designed for complete wear protection
Retrievable Choke and Flow Module
FMC Technologies' retrievable choke and flow module provides easy retrieval and deployment on a down line with ROV assistance, no running tool is required.

Features and Benefits:

  • Small compact footprint allows for 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
  • Upgradeable by adding retrievable flow meters and sensors
  • Sensitive components can be retrieved and deployed without performing major workovers
  • Improved reliability and availability with simplified interfaces
  • Utilizes a cost effective bolted bonnet design
  • Improved thermal performance due to simplified interface and ease of adding insulation onto entire choke body and actuator
  • Reconfiguration is contained in the flow module permitting standardization of core tree components
  • Allows for easy conversion from production tree to water injection service and vice versa
