Typical Challenges for Operators

 

Do any of these apply to your drilling operations?
  • One rig operating multiple fields and a dynamic rig schedule
  • Multiple subsea vendors and XT systems
  • System limitations with conventional systems
  • High cost with use of ROV and other tooling

 

Subsea control systems are a critical part of all operations linked to subsea wells. 4Subsea, with the prominent developers and technical experts from Astori on board, now delivers an innovative well access system for well intervention. The module may also be used as a subsea HPU for production.
