Installation and Workover Control Systems (IWOCS)

Disciplines: Management

Course Description

This 1-day course provides participants with a background review of subsea production control systems and specific knowledge of Intervention Work-Over Control Systems (IWOCS) as they interact with subsea productions systems. This is followed by an interactive class discussion of operations scenarios, illustrating IWOCS usage and some situational challenges encountered during subsea hardware installation and well interventions. 

Topics discussed will be:

  • Review of subsea production controls
  • IWOCS architecture and operating philosophy
  • Deployment methodologies
  • Safety and Well Control Protocols
  • Operational requirements for New Installations
  • Operational requirements for Well Interventions
  • Commissioning and Troubleshooting
  • Case history scenarios

Learning Level

Intermediate to Advanced

Course Length

5 hours (with 1 hour break for lunch)

Why Attend

This course will give you a better understanding of how IWOCS differs from other control systems, how its tailored to hardware installation and well intervention work, and better understand the operating philosophies behind well control and well integrity.

Who Attends

Trainees, offshore personnel, well site leaders, and completions/drilling engineers dealing with Subsea Intervention Operations

Special Requirements

  • Laptop or Smart phone for Downloading the app for Poll Everywhere
  • Participants should have some exposure to topic. Moderate experience or exposure to the topic will be a plus for the case study scenario session.
