Flowline modifications on semi-submersible rig

Drilling Contractor
Business Unit:

With only a few months to go before our client’s rig needed to be on location and drilling, the need for fast track modifications were identified.  With numerous stakeholders heavily involved and invested, this scope was perhaps not even possible, let alone financially viable, given the constraints of the schedule and the complexities fo the job.  However, Apollo were up for the challenge and set to work, maximising every opportunity to move the project forward safely and efficiently in spite of significant obstacles.  The key component that ensured success on this project was Apollo’s willingness and ability to effectively project manage the entire project, end to end – ultimately delivering ahead of schedule and ensuring enhanced drilling performance.



  • The drilling contractors client required fast track modifications on the mud flowline to accommodate a new flowmeter and add 3 automatic valves, remote monitoring and control system for the valves and flowmeter


  • Conducted offshore surveys and defined the scope, utilizing laser scanning as well as traditional methods to ensure the most accurate picture was built of the site
  • Provided a roadmap for execution, turning around swiftly as the rig was planned to mobilise to a new drilling campaign and the client wanted to install the system for testing
  • Solved multi-disciplinary engineering problems (piping, structural, electrical, instrumentation and controls) and provided a safe, functional solution
  • Provided a full, turnkey project - procuring equipment and materials on behalf of the client and mobilizing our construction team to install, test and commission the system


  • Apollo’s multi-discipline team used drilling specific knowledge, allowed valuable and effective communication across internal and external stakeholders, with the avoidance of confusion or duplication
  • Taking a full EPC / turnkey approach ensured our client piece of mind, quick progression and removed the need for management of multiple vendors
  • The project was fully executed ahead of schedule
  • Enhanced drilling performance was achieved, offering considerable commercial and operational benefits during a critical, high profile campaign
